Therefore, categorization of subjects on the basis of the estimated apparent age is suitable for further spectral analysis and the measurement of biological and chemical compounds, such as blood analytes. Furthermore, age determination of subjects has particular benefit in assessment of therapies used to reduce the effects of ageing in tissue and measurement of tissue damage.

An enhanced filling/weighing system utilizes first and second weighing stages. The first stage includes a first top container having an associated weighing device, e.g., a load cell. The second stage includes a second bottom container having an associated weighing device, e.g., a load cell. A high speed bulk feed subsystem supplies product to the top cup. A low speed dribble feed subsystem supplies product to the lower cup. In operation, the bulk feed subsystem feeds product to the top cut at a high speed. The top cup fills to its first setpoint (plus overfill, e.g., attributable to feed momentum) once per cycle. When the system controller recognizes that the top cup weight has reached the first setpoint, it pauses th bulk feed, discharges the top cup into the bottom cup, starts the dribble feed into the bottom cup, and starts the next cycle of bulk feed into the top cup. Thus, the top cup fills at high speed during cycle N+1 concurrently with the bottom cup filling at low speed during cycle N. When the system controller recognizes that the bottom cup weight has reached a second setpoint, the dribble feed is interrupted and the content is transferred out of the bottom cup awaiting the next transfer from the top cup.

A method and apparatus for evaluating the end cap round transducer horn assemblies used in debubbling operations wherein the ECR THA can be evaluated off-line at both high and low power and on-line by making electrical measurements on the ECR THA. The electrical measurements are used to characterize the physical condition of the piezoelectric ceramics of the THA. A test box is employed to practice the method. The test box is connected between the THA and a signal analyzer. Power is supplied to the THA and the electrical signals across the THA are sampled. The sampled electrical signals are transmitted to the signal analyzer while maintaining the amplitude and phase relationship thereof. The sampled electrical signals are used to generate an impedance trace for the particular THA. That impedance trace is compared to a model impedance trace. In such manner, it can be determined whether the ECR THA is operational. Further, if the ECR THA is in working condition, the impedance trace can be used to determine how efficiently it is operating. This allows for an ultimate determination to be made of how well a particular ECR THA is functioning.

Methods and compositions are disclosed for producing air-activated, i.e., oxygen (O2) activated, disinfectant-sterilent solutions. Solutions containing a haloperoxidase (i.e., a halide:hydrogen peroxide (H2O2) oxidoreductase, such as myeloperoxidase, eosinophil peroxidase or lactoperoxidase) plus a halide or combination of halides (i.e., chloride, bromide and/or iodide), an oxidase (i.e., a substrate:O2 oxidoreductase) capable of generating H2O2, and a substrate specific for that oxidase, are separately prepared under aerobic conditions, but all of the component solutions are made anaerobic prior to final combination and mixing. The anaerobic formulations are dispensed into containers capable of maintaining the anaerobic condition (e.g., pressurized canisters). Dispensing the solution at the time of use exposes the formulation to air (i.e., O2) which activates its disinfectant-sterilent properties. O2 is the rate limiting component for oxidase generation of H2O2. Under aerobic conditions the oxidase catalyzes the oxidation of its substrate and the reduction of O2 to generate H2O2. In turn, H2O2 serves as substrate for haloperoxidase which catalyzes the oxidation of halide to hypohalous acid. Hypohalous acid reacts with an additional H2O2 to generate singlet molecular oxygen (1O2). Hypohalous acid (e.g., hypochiorous acid) and especially 1O2 are potent microbicidal agents. Both haloperoxidase generation of hypohalous acid and its reactive consumption to yield 1O2 are dependent on the availability of H2O2. A high rate of H2O2 generation does not result in the accumulation of hypohalous acid, but instead results in a high rate of 1O2 production. The microbicidal capacity and toxicity of 1O2 are limited by the half-life of this metastable electronically excited reactant, and as such, disinfectant-sterilent activity is temporally defined by and confined to the dynamics of oxidant generation.

A light emitting device and a method of increasing the light output of the device utilize a chirped multi-well active region to increase the probability of radiative recombination of electrons and holes within the light emitting active layers of the active region by altering the electron and hole distribution profiles within the light emitting active layers of the active region (i.e., across the active region). The chirped multi-well active region produces a higher and more uniform distribution of electrons and holes throughout the active region of the device by substantially offsetting carrier diffusion effects caused by differences in electron and hole mobility by using complementary differences in layer thickness and/or layer composition within the active region. Thus, the chirped design of the multi-well active region increases the probability of radiative recombination of electrons and holes within the light emitting active layers of the active region, which results in an increased light output of the device. The multi-well active region of the device may be chirped with respect to light emitting active layers and/or barrier layers of the active region. The light emitting device may be a III-V material LED, a II-VI material LED, a polymer or organic LED, a laser diode or an optical amplifier.

In an optical printing apparatus, an image having a high image quality is desirably produced under stable condition, even when variations occur and exposure conditions are different from each other, which are caused by differences in response speeds of a light source and a liquid crystal shutter element, and also by differences in element driving conditions. The optical printing apparatus is arranged by including: image data input for inputting image data; reference level generator producing a reference level; comparator for comparing multi-value data outputted from the image data input with the reference level so as to convert the multi-value data into binary data; data transferring element for transferring the binary data outputted from the comparator as head data to the print head; latch controller for latching data of the print data; and strobe controller capable of causing the print head to expose the light therefrom. Then, the liquid crystal shutter element corresponding to a non-recording pixel is also ON/OFF-driven. Accordingly, deterioration in the image quality and color shifts, which are caused by a difference in driving intervals, can be solved.

An object oriented mechanism and method allow allocating a greater number of objects on a method's invocation stack. Each instruction that creates an object (i.e., allocation instruction) is first analyzed to determine whether it is one of the following three types: no escape, global escape, and arg escape. If an allocation instruction is global escape, the object must be allocated from the heap. If an allocation instruction is no escape, it can be allocated on the method's invocation stack frame. If an allocation instruction is arg escape, further analysis is required to determine whether the object can be allocated on an invoking method's stack or must be allocated from the heap. If the method that contains an arg escape allocation instruction can be inlined into a method from which the lifetime of the object does not escape, the object can be allocated on the invoking method's stack. This inlining can be done for several layers up, if needed and possible. This allows for nested objects to be potentially allocated on a method's stack, instead of forcing each of these objects to be allocated from the heap.

If there are free result slots available, the proper compares are generated and folded into the initialization. If no free slots are available, it is determined if there is a use of a gp between the dp and gp. If not, the dp is renamed to gp, and the proper compares are generated and folded into the initialization. If there is such a use, the guarding predicate of the compares is found and the process reiterates until it ends with the failure to find a new dominating predicate dp.

An improved blocking member and vegetation barrier for the bottom of fences. A ground covering member has first and second opposite ends and opposite rolled under edges, and it somewhat rigid but somewhat flexible. The ground covering member can be placed directly on the ground even if the ground undulates relative to the fence bottom, and can be kept in that position once the riser is secured to the fence. The ground covering member can be resilient and create reactionary force if it is pressed against the ground. This can further assist in maintaining the blocking member and vegetation barrier in a fixed position relative the ground and the fence. The device can be made in lengths that can be interconnected with one another and/or installed between fence posts.

There is provided a method by which lightly doped drain (LDD) regions can be formed easily and at good yields in source/drain regions in thin film transistors possessing gate electrodes covered with an oxide covering. A lightly doped drain (LDD) region is formed by introducing an impurity into an island-shaped silicon film in a self-aligning manner, with a gate electrode serving as a mask. First, low-concentration impurity regions are formed in the island-shaped silicon film by using rotation-tilt ion implantation to effect ion doping from an oblique direction relative to the substrate. Low-concentration impurity regions are also formed below the gate electrode at this time. After that, an impurity at a high concentration is introduced normally to the substrate, so forming high-concentration impurity regions. In the above process, a low-concentration impurity region remains below the gate electrode and constitutes a lightly doped drain region.

A three electrode plasma display panel (PDP) operates in concurrent sustain and addressing periods, rather than separating the sustain and addressing periods. Because of this concurrent operation, a PDP with a brighter display is produced. Crosstalk between sustain electrodes and the column electrodes of non-selected rows is mitigated by implementing column voltages such that there is no difference in crosstalk brightness levels in non-addressed pixels in the on state compared to non-addressed pixels in the off state. This is accomplished by choosing column voltages that are approximately symmetric about one-half of the sustain voltage.

Emerging patterns (EPs) are itemsets having supports that change significantly from one dataset to another. A classifier, CAEP, is disclosed using the following main ideas based on EPs: (i) Each EP can sharply differentiate the class membership of a (possibly small) fraction of instances containing the EP, due to the big difference between the EP's supports in the opposing classes; the differentiating power of the EP is defined in terms of the EP's supports and ratio, on instances containing the EP. (ii) For each instance t, by aggregating (124) the differentiating power of a fixed, automatically selected set of EPs, a score is obtained for each class (126). The scores for all classes are normalized (144) and the largest score determines t's class (146). CAEP is suitable for many applications, even those with large volumes of high dimensional data. CAEP does not depend on dimension reduction on data and is usually equally accurate on all classes even if their populations are unbalanced.

A tomographic spray momentum mapping system and method of use for determining the spray momentum of dense, high-pressure sprays such as petroleum-based fuel sprays discharged from electronically-controlled fuel injection systems is disclosed. The present system comprises a mechanical probe assembly having a probe wire drawn across a Y-shaped handle, which includes a force transducer attached in operative relation thereto that receives force input from the impact of the spray impinging on the probe wire and generates output signals in response thereto. The probe assembly is traversed through the spray to obtain force measurements at selected points therein. The present system includes a coordinate measuring apparatus for precisely positioning the probe wire within the spray structure. The output signals derived from the transducer are processed through signal conditioning electronics and input to a computer system, which utilizes a computed topography software program to process the force measurements and convert the integrated measurements into tomographic reconstructions showing the spray momentum distribution in a two- or three-dimensional domain. This information is used directly for understanding spray structure and improvement of injection systems, and indirectly for improvement of computer spray models used to simulate engine performance.

The present invention has several aspects to it, one of which is the provision of a chisel point which is straight and tapered from its thinnest part at the extreme front to a thicker part at the rear thereof for causing a sweep to wear longer than prior art sweeps. This sweep also improves soil penetration and is self-sharpening. Another aspect of the present invention is to provide an earth working sweep having a front end, a right side, a left side, and a central upper portion for connecting the sweep to an implement. It also has a right rear wing portion and a left rear wing portion with an intermediate portion connecting the front end to the central upper rear portion and the left and right rear wing portions. A right edge and a left edge have concave edges on the front and convex edges on the back so as to form a somewhat S-shaped configuration which reduces scrap when being made and adds to the longevity and performance of the sweep. Another aspect of the present invention is a method of making a ground engaging sweep from a sheet of metal which has two parallel sides, a first end and a second end. The edges of the sweep are cut so that the right side of one sweep is a mirror image of the left side of the next adjacent sweep so that no material is wasted therebetween as they are cut from one sheet of material. By using this method, as much metal as possible is utilized in the sweep itself rather than having wasted metal as scrap and thereby enhancing the life and performance of such sweep.

A disc brake assembly includes a stationary member, a rotating member defining an axis of rotation, a plurality of stationary discs spaced axially along the axis of rotation within the stationary member, and a plurality of movable discs interspaced with the stationary discs. A brake coupler supports the movable discs. During non-braking vehicle operation, the movable discs and the brake coupler remain stationary relative to the stationary discs. During a braking maneuver, the coupler couples the movable discs to the rotating member such that the movable discs are caused to rotate with respect to the stationary discs. Once the coupler and rotating member are interconnected a piston moves the stationary and movable discs together to reduce rotation of the rotating member and brake the vehicle. Once the braking maneuver is completed, a first return spring moves the stationary and movable discs apart and a second spring disengages the coupler from the rotating member to return the movable discs to their original position. This eliminates undesirable drag that occurs between stationary and rotating discs in a disc brake during non-braking vehicle operation.

A lightweight cathode ray tube is formed by reducing a cross-sectional area on the apeture grill tapes in the aperture grill. One exemplary embodiment of the reduced cross-sectional area aperture grill tape includes a central longitudinal channel in a side of the aperture grill tape that faces away from the screen. The reduction in cross-sectional area reduces a linear density of the tape thereby decreasing the tension required by the frame. As each of the aperture grill tapes includes this central longitudinal channel, the weight of the overall aperture grill is significantly reduced and the aperture grill frame weight is reduced due to the lower aperture grill tension. A method for producing the reduced cross-sectional area aperture grill tape is possible without significantly increasing the cost of manufacturing the aperture grill tape. One exemplary embodiment of this method includes a two-step etching process, in which one of the etching steps involves etching both sides of the aperture grill, during which step a central longitudinal channel is etched in each of the aperture grill tapes and the other etching step involves etching the screen side of the aperture grill only.

An efficient process is described for making rubber tube segments, such as lathe-cut gaskets or conveyor roller covers, by cross-head extrusion of uncured rubber onto an axially aligned string of mandrels. Each mandrel in the string is separated from its two neighbors by respective spacers. The outer diameter of the extruded tube is kept within precise tolerances by making a non-contact measurement of the outer diameter at the output from the extruder and using the measured diameter to control the extrusion process. The extruded tube is cut into segments by a cutter that acts responsive to a spacer sensor and that makes the cuts between the mandrels. In one version, the extruded tube is conveyed through a curing oven by apparatus that only contacts and supports the tube adjacent ones of the spacers.

A method and device for increasing the horizontal resolution of both a color flat panel display and a cathode ray tube (CRT) display. The method involves fine horizontal positioning of pixels according to information encoded in the color. Since pixel size is not changed, the display and processing bandwidth requirement is not increased. For the case of the color flat panel display, the fact that each pixel is constructed of a horizontal stripe of 3 primary color sub-pixels is utilized. Complex color information is spread across adjacent pixels to increase the apparent horizontal resolution by a factor of three. For the case of the CRT, a clock multiplier is used to multiply the video clock frequency by three. The apparent horizontal resolution of the CRT is increased by a factor of three by delaying pixels a varying multiple of this high clock speed. By encoding the fine repositioning information in the pixel color, the same display output can be post-processed respectively for the color flat panel and the CRT, allowing them to be driven and resolution enhanced simultaneously.

The thin film magnetic head of the present invention includes an improved P2 pole tip/yoke interface structure. The interface structure includes yoke material that is formed in a concave curved shape at the interface between the P2 pole tip and the yoke, such that a right angle interface between the P2 pole tip and the yoke is eliminated. The process for forming the P2 pole tip/yoke interface includes a second CMP polishing step that is performed on the surface of the write head wafer subsequent to the plating of the P2 pole tip thereon, and subsequent to a first CMP step. This second CMP step utilizes a relatively soft polishing pad and an acidic polishing slurry having a pH within the range of approximately 1 to approximately 5, and preferably approximately 2.5. The acidic polishing slurry contains a chemical agent which preferentially attacks the P2 pole tip material, such that the second CMP step results in the recession of the upper surface of the P2 pole tip relative to the dielectric layer surrounding it, as well as the significant rounding of the upper edges of the dielectric trench in which the P2 pole tip is formed. Thereafter, when the yoke is plated onto the P2 pole tip the rounded upper edges of the dielectric trench result in a concave curved interface between the yoke and the P2 pole tip. The resulting P2 pole tip/yoke interface possesses improved magnetic flux flow control properties and results in decreased side writing. Greater track per inch areal data storage results from the reduced side writing of the improved write head.

The present invention incorporates an optical fiber cleaving mechanism within a prior art optical fiber impact mounting device. The optical fiber cleaving mechanism is pivotally mounted within the fiberoptic connector holding mechanism, such that an optical fiber cleaving blade is disposed proximate the tip of the fiberoptic connector. After the optical fiber has been engaged within the fiberoptic connector an end of the optical fiber protrudes from the tip of the fiberoptic connector. An actuator member is then manipulated to cause the optical fiber cleaving mechanism to rotate downwardly, such that the cleaving blade will make cleaving contact with the surface of the optical fiber. Immediately prior to the contact of the cleaving blade with the optical fiber, a portion of the cleaving mechanism makes contact with the protruding end of the optical fiber to bend it downwardly, and the subsequent contact of the cleaving blade will cleave the optical fiber. In the preferred embodiment, the cleaving blade is movably mounted, such that it makes a scoring contact with the optical fiber to aid in the cleaving process. After the cleaving step, the optical fiber is mounted within the fiberoptic connector and its protruding end has been cleaved, whereupon it is removed from the apparatus for subsequent polishing.

A system and method for data communication with adaptive security in which a send host transmits a data stream to a receive host in packets which contain an authentication data block with an authentication header and a signature block. The authentication header advantageously contains various fields including a verification type, a security algorithm, a minimum security level, a target security level, and an actual security level. The receive host adaptively performs verification of the data packets using varying security levels based in part on the availability of security operations per second (SOPS) in the receive host. Where a data stream in the receive host is delayed by a security processing bottleneck, the receive host may alter the verification type, security algorithm, or the actual security level to speed up the processing of the data stream by reducing the amount of security processing performed. The receive host further allocates the SOPS among the data streams received based on a priority assigned to each data stream.

Status Date: 2015-02-16

A method and apparatus are disclosed for efficiently creating and maintaining a remembered set in a generational garbage collection scheme using a write buffer and a barrier bit associated with each object. A barrier bit associated with each object differentiates generations in a generational garbage collection scheme. When an object is first created, the barrier bit of the object is set to zero. The barrier bit is set when the object becomes old, for example, after surviving a first garbage collection. The barrier bit is used to determine whether to make an entry into a write buffer when a reference to another object is stored into an object. An entry is made in the write buffer only if the barrier bit of the object that is written into is set. At the end of each garbage collection, entries in the write buffer are added to the remembered set for the next garbage collection if the objects satisfy the criterion for membership, i.e., they are live and may contain pointers to objects in a younger generation. Thus, the remembered set consists of objects that were in the write buffer at the time of a garbage collection, that must be remembered for the next garbage collection. The write buffer is kept small by eliminating duplicate entries. The present invention turns off the barrier bit after the first store during each reclamation period (which causes the object to be identified in the write buffer). The barrier bit is turned on again by the garbage collector after the write buffer has been processed.

A method for fabricating an Invar tool includes the step of superplastically forming an Invar facesheet for the tool. A tool header is provided, and the Invar facesheet is then formed with an SPF diaphragm driver to match the predetermined contour of the tool header. The Invar facesheet is then welded to the tool header. Forming the Invar facesheet is achieved by positioning the Invar facesheet between a superplastically formable diaphragm and a die having the predetermined contour. The diaphragm is heated to a predetermined superplastic temperature, and a predetermined pressure is applied to the diaphragm. Application of the predetermined pressure allows the diaphragm to cause the Invar facesheet to form against the predetermined contour of the die. Superplastically forming the Invar facesheet results in a negligible amount of excess scrap, reduces material costs, and reduces labor costs.

Sets of coefficient polynomials are used to design embedded-component architectures that have capability for asynchronous parallel execution at an advantageous arithmetic level where algebraic merging is realized with other operations, algorithms or applications. Because of the particular hardware structures made possible by the use of CPA, higher computational granularities and complex modules are more easily feasible than by using conventional arithmetic and, additionally, increased efficiency is obtained for algorithmic computations involving single and multiple operations. This is achieved by the merging of operations and the integration of algorithms, and thereby avoiding the necessity of performing the entire basic arithmetic separately for each operation or algorithm. In the Asynchronous Parallel Arithmetic (APA) Processor Utilizing Coefficient Polynomial Arithmetic (CPA), the various sets of coefficient polynomials represent the merged operations or algorithms at much earlier time slots and their resolution to the final result level is accomplished with notably increased efficiency when compared to conventional structures.

Provided is a compact power actuator which is simple in structure, reliable in operation, and easy to install. The power actuator comprises a piston assembly which is received in a fixed cylinder for either directly or indirectly engaging a vehicle occupant restraint member, and a propellant for rapidly increasing the inner pressure of the cylinder to push the piston assembly outward so that the restraint member may be instantaneously driven. A spring is interposed between the piston assembly and the propellant to urge the piston assembly in the projecting direction. The front end of the propellant fits into the central opening so that the available space may be fully utilized. Therefore, the size of the power actuator can be reduced, and the required amount of the pyrotechnic material for the propellant can be reduced due to the reduced initial volume of the chamber for the expansion of the generated gas.

A method and apparatus for determining the mean arterial blood pressure (MAP) of a subject during tonometric conditions. In one embodiment, the apparatus comprises one or more pressure and ultrasound transducers placed over the radial artery of a human subject's wrist, the latter transmitting and receiving acoustic energy so as to permit the measurement of blood velocity during periods of variable compression of the artery. During compression, the ultrasound velocity waveforms are recorded and processed using time-frequency analysis. The time at which the mean time-frequency distribution is maximal corresponds to the time at which the transmural pressure equals zero, and the mean pressure read by the transducer equals the mean pressure within the artery. In another aspect of the invention, the ultrasound transducer is used to position the transducer over the artery such that the accuracy of the measurement is maximized. In yet another aspect of the invention, a wrist brace useful for measuring blood pressure using the aforementioned apparatus is disclosed.

High density, photon-gated persistent spectral holeburning is effectuated in rare earth doped II-VI compounds such as MgS, CaS, BaS and SrS. Two-photon ionization of rare earth ions is performed, selected by a narrow band laser, producing narrow regions of reduced absorption (optical holes) in the absorption spectrum of a rare earth ion. These holes are useful for such applications as high density memory (especially, high density re-writable or photo-erasable memory), spectral holographic memory, communication, etc., and demonstrate great survivability over reading cycles, thermal cycles and elevated temperatures. The embedment of the rare earth doped II-VI compound in a matrix comprising a polymeric material (such as PMMA), prior to the effectuation of the holeburning, may be advantageous for many embodiments. Inventive practice has successfully burned two hundred forty photon gated spectral holes in the zero phonon line (ZPL) of the 4f-5d transition of Eu2+ in a magnesium sulfide host. CaS:Eu, CaS:Eu,Sm and MgS:Eu are among the materials which have demonstrated a very high density of spectral holes.

The back surface of a BOE (binary optical element) having a binary optical structure formed thereon is coated with a resist film. Chromium is then deposited on the BOE by means of electron beam evaporation so as to form an island structure with an island size of about 50 nm and an island-to-island distance of about 80 nm. The BOE is then etched with an etchant to a depth of 55 nm using the island structure as a mask thereby forming a pillar-shaped microstructure. The island structure used as the mask is removed by means of wet etching using an etchant, and the resist film on the back surface of the BOE is removed using a resist remover. Thus, a microstructure is obtained which has antireflection capability allowing suppression of reflection to a level of 1% or less for a wavelength of 248 nm.

A nonplanar substrate surface is substantially uniformly planarized by a chemical mechanical planarization (CMP) process. The CMP process uses multiple sources of slurry delivered in between a slurry distribution screen and a slurry membrane of the CMP apparatus. The multiple slurry sources have differing chemical and physical compositions, and are delivered to different locations along the membrane. The slurries bleed into each other during polish to form a radially-variable, slurry abrasiveness concentration gradient. As a result, there are areas with a greater abrasiveness concentration of slurry, and hence a greater frictional contact. The slurry flow rate and concentration is adjusted along the wafer surface according to the non-uniformly planar areas of the wafer. Consequently, uniform planarization is substantially achieved.

Electron beam lithography is used to make very small mechanical structures in single-crystal silicon. The structure may be a mesh having beam widths of less than 30 nm and suspended in a wafer, above a substrate. An rf drive voltage applied between the suspended structure and the underlying substrate produces vibration at or near the resonant frequency of the structure, and optical interference techniques are used to detect and measure the motion of the structure. The small dimensions of the structure provides a resonant frequency above 40 MHz. In one embodiment, the structure is a mesh formed of interconnected, very narrow, high aspect ratio parallel beams spaced about 315 nm apart. This results in a nanostructure having a low mass and a large relative surface area. The mesh is illuminated by laser light having a wavelength greater than the spacing between adjacent beams in the mesh so that small amplitude oscillations can be measured, with the detected change in optical reflection being proportional to the drive amplitude. The suboptical-wavelength features of the mesh provide a high measurement sensitivity, so that small changes in the mechanical properties of the mesh, resulting in corresponding small changes in the amplitude of the vibration, can be detected. A variable DC bias voltage applied to the vibrating structure allows adjustment of the motion of the structure and tuning of its vibration.

The process for the manufacture of the rib waveguide (4) is based on the process steps (a) ion implantation of high-energy light ions into a crystal, (b) the application of a mask to the surface (11.1) of this crystal, which defines strips, and (c), the etching of a rib (41) onto the surface (11.1) of this crystal. The process step (a) (ion implantation) causes the formation of a layer (14) with a reduced refraction index at a depth of some micrometers below the surface of the crystal (11.1). By this refraction index barrier (14), the light in the direction vertical to the surface of the crystal is restricted. The lateral guidance of the light is effected by the lateral limits (43.1) and (43.2) of the rib (41).The process is in particular suitable for the manufacture of waveguides in non-linear optical crystals, e.g., ferro-electric oxides (KNbO3, LiNbO3, etc.) and borates (LBO, BBO, etc.). These crystal classes have interesting non-linear-optical characteristics and are suitable for utilization as frequency converters. The manufacturing process in accordance with the invention, in particular the combination of ion implantation and the etching of a rib structure, is adapted to the particular characteristics of the material and enables the manufacture of rib waveguides with a low attenuation, whereby the non-linear optical characteristics of the crystal are maintained. This is an important prerequisite for achieving an efficient frequency conversion.

A playing card, wagering game method where each player antes one unit. The dealer will deal four cards down to each player and four cards down to himself. Each player evaluates their hand and elects to either fold or challenge the remaining players and dealer. Any player who folds, surrenders his ante to the house. The total amount of antes remaining after each player evaluates his hand will be referred to as the “ante pot”. All players electing to remain, or challenge, (including the dealer), must wager an amount equal to the ante pot. The dealer always challenges the pot. After each player has elected to either fold or challenge, the dealer, after “burning” a card, will deal or “flop” another three community cards to be used by all challenging participants. The highest poker hand of each participant using their initial four cards plus the three community cards wins the pot. The first player to act is determined on a rotating basis to eliminate position advantage. Single player versus the dealer has the option to double the “ante pot,” resulting in the dealer likewise adding to the ante pot.

In a processing system having a main memory, wherein information is stored in a compressed format for the purpose of gaining additional storage through compression efficiencies, a method and apparatus for providing compressed data integrity verification to insure detection of nearly any data corruption resulting from an anomaly anywhere in the logical processing or storage of compressed information. A cyclic redundancy code (CRC) is computed over a compressed data block as the data enters the compressor hardware, and the CRC is appended to the compressor output block before it is stored into the main memory. Subsequent read access results in comparing the CRC against a recomputation of the CRC as the block is uncompressed from the main memory. Any CRC miscompare implies an uncorrectable data error condition that may be used to interrupt the system operation.

A cost-efficient digital CATV network to improve signal quality, provide reliability, and offer the ability to meet demands for interactive services is described. Analog or digital video downstream channels are converted to a digital format by a digital headend transmitter. Relatively costly error-encoding for digital video channels is also part of the digital headend transmitter. Downstream analog and digital video channels in the digital format are transmitted using time-division multiplex technology from a headend to nodes using standard network protocols, such as SONET. Standard network protocols provide error-monitoring and status indication of transmit data, thus ensuring high signal quality and reliability. Time-division multiplexing facilitates easy adding or dropping of information to a transmit path. Flexibility to add or drop information is critical in providing interactive services. Data from interactive services can be added or dropped at points of presence throughout the digital CATV network. Subscribers to the digital CATV network can communicate with each other. A digital node transmitter receives the analog or digital video channels in digital format and converts the analog or digital video channels into an analog format. The digital node transmitter also frequency-division multiplexes multiple analog or digital video channels into one analog broadband signal for broadcast to subscribers' homes.

A process for resetting or initially establishing the magnetic orientation of one or more spin valves in a magnetoresistive read head with improved robustness. The spin valve includes subcomponents such as an antiferromagnetic layer, a ferromagnetic pinned layer, a conductive layer, a free layer, and a hard bias layer. A first external magnetic field is first applied to the spin valve sensor, this field having a first orientation relative to the spin valve sensor. During application of the first external magnetic field, a pulse of electrical current is directed through the spin valve sensor in a first direction, preferably parallel to the magnetic orientation of the external field. The current waveform brings the antiferromagnetic layer of the spin valve past its blocking temperature, freeing its magnetic orientation. The first external field exerts a robust bias upon the antiferromagnetic layer in the desired direction. Depending upon its flow direction, the current pulse may contribute an internal magnetic field that cooperates in magnetically biasing the antiferromagnetic layer as desired. After the current pulse, the antiferromagnetic layer cools below its blocking temperature, retaining the desired biasing. After the first external field is removed, and a second external magnetic field may be applied to the spin valve sensor for a predetermined time. The second external field is oriented to magnetically direct the hard bias layer of the sensor, thereby establishing the quiescent magnetization of the sensor's ferromagnetic free layer.

Each bone in the skeleton is defined in relation to its parent bone and the topmost bone in the hierarchy is the root bone. When a bone in the skeleton is animated, all of the bones below the animated bone in the hierarchy are also animated. An animation for a bone is specified using a directed acyclic graph (DAG) having one or more nodes. The nodes are either data generation nodes (DG nodes) or combiner nodes. DG nodes have zero or one input and have one output that outputs animation data. DG nodes having zero inputs include fixed, pre-generated, tracking, reverse, mirror, and noise nodes. DG nodes having one input include limit and reflect nodes. Combiner nodes have two inputs for receiving animation data and one output that outputs animation data. Combiner nodes include overlay, blend, and transition nodes. When a bone is animated, the bone polls its associated DAG, if any, and provides the DAG with the time elapsed since the last poll. The topmost node of the DAG recursively polls the lower nodes until DG nodes are reached and the animation data reaches the top node. This animation data animates the bone. Using DAGs in this manner allows transitions between different animations to be smoothed and makes looped animations appear more realistic.

This invention provides a plano-multiradius reflective element assembly suitable for use in an exterior sideview mirror assembly mounted to the side body of an automobile. The plano-multiradius reflective element assembly includes a plano reflective element which has a rearward field of view, when mounted in an exterior sideview mirror assembly mounted to the side body of an automobile, with unit magnification. The plano-multiradius reflective element assembly also includes an auxiliary reflective element including a multiradius portion with a rearward field of view. The plano reflective element provides a distortion-free rearward field of view and serves as the principal rearward-viewing portion of the plano-multiradius reflective element assembly. The multiradius portion provides a wide angle rearward field of view, and typically supplements the rearward field of view of the plano portion. The plano reflective element and the multiradius portion are separated by a demarcation element which enables the driver to readily delineate a rearward view in the plano portion from a rearward view in the multiradius portion. The plano reflective element and the multiradius reflective element are individually, separately, and adjacently attached to a single backing plate which is mounted to an actuator of the exterior sideview mirror assembly. By adjusting the position of the backing plate within the housing of the exterior sideview mirror assembly via the actuator, the rearward field of view of both the plano reflective element and the multiradius reflective element are simultaneously and similarly aligned.

A method and system are shown for handing off a communication stream between a mobile node and a communication endpoint from a first connection initiator to a second connection initiator while maintaining call state for the communication stream. The first connection initiator establishes a first connection to the communication endpoint in response to receiving a first connection request from the mobile node that includes a client identifier value for the mobile node. When the first connection initiator detects loss of communication with the mobile node, it sends a call-disconnect-notify (CDN) message having a cause code set to a handoff value to the connection endpoint. The connection endpoint, in response to the CDN message, stores call information for the first connection along with the mobile node's client identifier value. The first connection initiator also broadcasts a user-moved message that includes the mobile node's client identifier value and the first connection initiator's call information for the first connection. The second connection initiator, upon receiving the user-moved message, stores the first connection initiator's call information from the message along with the mobile node's client identifier value. When the second connection initiator receives a second connection request from the mobile node having the mobile node's client identifier value, it retrieves the call information from the user-moved message using the client identifier value and sends a tunnel-handoff-request message, which includes the client identifier value, to the connection endpoint. The connection endpoint retrieves its call information for the first connection using the client identifier value and sends a tunnel-handoff-response message to the second connection initiator. The second connection initiator and the connection endpoint then resume the communication stream using the call information for the first connection.

Principal features are inventively derived from a non-stationary time series signal, and can be used to classify the attributes of the signal. Intrinsic to the invention is its recognition of the value of information contained within singular vectors. The invention therefore seeks to render singular vectors as proper density functions for purposes of formulating at least one feature of a signal, which is or has been sensed. To this end, the signal is typically evaluated thusly according to the invention: a time-frequency distribution (e.g., positive time-frequency distribution) matrix is generated; the time-frequency distribution matrix is decomposed; an element-by-element square of singular vectors is performed; the non-principal singular values are sorted and truncated; density functions are obtained; the density functions are normalized; and, at least one feature from the normalized density functions is formulated. The invention admits of utilization of any time-frequency distribution pursuant to the general formulation of Leon Cohen, first expounded in 1966; a positive time-frequency distribution may prove especially propitious for many applications.

Register allocation during computer program code compilation is accomplished by determining a set of spill candidates, by evaluating a cost function for each spill candidate using a plurality of spill strategies, and by selecting the spill candidate having the lowest cost function value. Preferably, the set of possible spill candidates is determined by the Chaitin method of constructing an interference graph of all live ranges of symbolic registers, and iteratively removing nodes and placing them on a stack. Preferably, multiple spill strategies are represented as varying numbers of deaths N of live ranges of other symbolic registers, a spill strategy N signifying that spill code is introduced whenever the number of deaths occurring between two successive uses of a symbolic register equals or exceeds N. In the preferred embodiment, the cost is a function of the number, type and frequency of each operation introduced by the spill, and is divided by a benefit factor represented as the degree of the node.

In a polymer electrolyte fuel cell system, a condition of humidification of electrolyte membranes is precisely determined, and adjustment is performed so that the condition of humidification of the electrolyte membranes substantially remains within a proper range. The system determines a condition of humidification of the electrolyte membranes of the fuel cell based on a differential value of the resistance of the fuel cell detected by a resistance detector when the electric current outputted by the fuel cell equals a predetermined value. The current from the cell is detected by an ammeter. The fuel cell is formed by stacking electrically conductive electrodes and separators, and proton-conductive electrolyte membranes. The electric conductivity of the electrodes and the separators is not affected by the humidification condition thereof, whereas the proton-conductivity of the electrolyte membranes greatly changes depending on the condition of humidification thereof. Therefore, the changing rate of the resistance of the fuel cell directly represents the changing rate of the proton-conductivity of the electrolyte membranes, so that the humidification condition of the electrolyte membranes can be precisely determined.

An optical alignment system used in the manufacture of semiconductor integrated circuits determines and adjusts the alignment between features which have been formed on a semiconductor wafer and features on a mask which is being projected onto the semiconductor wafer. Light which illuminates the semiconductor wafer is scattered and diffracted into a dark-field detector system. This results in the generation of electrical signals which are used to position the mask relative to the semiconductor wafer. The use of polarized light in the present system results in an increase in the magnitude of the desired signals and a decrease in the magnitude of the spurious signals. To improve the quality of the signals, the angle of polarization of the light is adjusted to a specific relationship with respect to the geometry of the alignment marks on the semiconductor wafer.

This invention pertains to a basic multi-technology application of cascaded beam-formers. A dual MEMS-EO technology platform method involving a two axis deflection micro-mirror cascaded with a three dimensional electro-optical beam-former such as a multi pixel liquid crystal device forms a powerful reflective control site for an incident beam, thereby inherently providing a robust beam control with both coarse and fine beam control capabilities in three dimensions. The electrically controlled two axis micro-mirror is excellent in providing the large angular beam deflections, while the liquid crystal device provides excellent small-beam deflections. This leads to a mechanically robust beam control module. A multipixel MEMS mirror device option coupled with the EO device can also provide simultaneous multi-beam generation capability. Furthermore, use of macro-pixels for both the MEMS and EO devices provides resistance to single pixel dependent catastrophic failure for the overall module. The mirror two-axis control can be supplemented with additional translational mirror motion, giving the ultimate option of cascading two 3-D beam-formers.

The inventive mechanism operates to optimize program efficiency in a two phase process. In the first phase, the mechanism conducts a dependency analysis on the instructions to determine dependency relationships between the various instructions in an instruction window. The mechanism thereby identifies candidates for register renaming and instruction speculation, and provisionally performs the renaming and speculation operations, while preserving information which is preferably used to reverse these operations in the second phase if it is determined that the operations may be effectively rescheduled. In the second phase, the mechanism determines whether the optimizing operations, renaming and speculation, were beneficial in each case. Each instruction for which the mechanism finds the optimizing operation to be beneficial will generally remain in optimized form. Optimizing operations found not be beneficial are generally reversed by the mechanism. The mechanism thus selectively uses renaming and speculation operations so as to ensure that the benefits preferably outweigh the costs of the operation in each case.

A structure and method of mounting semiconductor devices which can cope with miniaturization and high-speed transmission by embedding a semiconductor device within a wiring layer or transmission path formed between opposite sides of a substrate even when a plurality of semiconductor devices are mounted on the substrate. A semiconductor device is interposed between wiring layers or transmission paths formed on opposite sides of a substrate, thereby shortening the distance between the wiring layers and rendering a structural body compact oerall. As a result of shortening of the distance between the wiring layers, the electrical resistance value of the structural body can also be diminished. Consequently, the electrical characteristic of the mount structural body can be improved, and high-speed transmission becomes feasible. Alternatively, a semiconductor device is cylindrically formed so as to enclose a conductive wire, thereby realizing a high electrical characteristic. External terminals can be led from the entire side surface of the cylindrical structural body, thereby increasing the number of external terminals per unit mount area and rendering the structural body compact.

A bandpass filter makes use of at least one waveguide cavity that is thermally compensated to minimize drift of a resonant frequency of the cavity with thermal expansion of cavity components. The compensation relies on deformation of the shape of at least one cavity surface in response to thermally induced dimensional changes of the cavity. A control rod is used to limit the movement of a point on the deformed surface, while the rest of the surface moves with the thermal expansion. The control rod is made of a material having a coefficient of thermal expansion that is significantly different than that of other filter components. The rod may also be arranged to span more thermally expandable material than defines the filter such that, as the filter expands, the point of deflection is moved toward the interior of the filter beyond its original position. In an alternative embodiment, an end plate of each cavity is secured to the rest of the cavity along its periphery, and has a convex shape facing away from an interior of the cavity. As the cavity expands radially, it forces the convexity of the end plate inward, compensating for the expansion in other cavity dimensions.

An image scanner in which an original is scanned by a trilinear CCD array, i.e. the original is scanned line by line, three lines at the time, one line for each color. Thus, at a specific time “only” the area of the original that is scanned by the trilinear CCD array at that time has to be positioned in focus of the imaging means of the image scanner while the remaining part of the original may be positioned anywhere and may adopt any suitable form. Thus, there is no need for all parts of the original to be kept flat and planar as required in known flat bed scanners. The original is kept flat and straight along a line to be scanned by imparting a substantially cylindrical shape, such as a circular cylindrical shape, to at least part of the original. The original is scanned along lines that are substantially parallel to the generatrix of the cylindrical part of the original. Thus, the fact that all parts of the original are not scanned simultaneously is exploited to simplify the positioning of the original in the image scanner.

Candidate locations in which each of the components is to be placed are assumed. Initially, all the cells on a printed circuit board are the candidates. The range of candidates for the location of each component is narrowed down in some way (for example, the farthest cell from a fixed component is excluded from candidates for the location in which a component that directly relates to the fixed component is to be placed). An approximation problem is created from an original placement problem and a solution that optimizes the approximation problem is find. This solution is a feasible solution of the original placement problem as well. The process of narrowing down the candidates and solving the approximation problem is repeated until one candidate (or more than one candidate having an equal evaluation value) is found ultimately to determine the placement of the component.

If so, the subsumption test is performed on two subqueries. Then, the compensation predicate is applied to one of them, to perform the QGM transformation of the query. One subquery block is stacked on top of the other subquery block, in order to eliminate one subquery. This procedure allows the transformed query to perform more efficiently than the original query while providing same results. The query is then executed in the computer to efficiently retrieve data from the relational database.

A contact is defined by an opening etched into borophosphosilicate glass (BPSG) down to a silicon substrate. In a contact cleaning process designed to remove native oxide at the bottom of the contact with little effect on the BPSG, the contact is dipped in an etch retardant before being dipped in a cleaning solution containing both the etch retardant and an etchant. The dip in etch retardant modifies the surface of the BPSG, thereby lessening the enhanced etching experienced during the initiation of the dip into the etchant/etch retardant cleaning solution. Results of a etchant/etch retardant clean, both with and without the prepassivation, can be illustrated on a graph depicting the change in contact diameter as a function of dip time. Specifically, the results define “best fit” lines on that graph. For a given dip time, a first line representing the prepassivation+etchant/etch retardant clean is 30 to 40 Angstroms lower than a second line representing the prior art clean using the etchant/etch retardant without prepassivation. Accordingly, the first line's Y-axis intercept, representing the “zero dip time,” is also 30 to 40 Angstroms lower than the second line's zero dip time.

The invention relates to a method for transferring special cell information in a communications system and a cellular system and mobile station realizing the method. The invention can be advantageously applied to cellular systems specifying cell-specific services for users, such as cell-dependent charging. An idea of the invention is that special cell identities are transferred from a mobile station to a base station system in coded form (521, 522) in such a manner that the transfer of special cell identity information uses fewer bits than what would be needed for the transfer of special cell identities as such. Cell identities are advantageously chosen such that the cell identities of a single area can be coded using a small number of bits. In accordance with the above-mentioned principle according to the invention the transfer can be carried out advantageously in such a manner that the first special cell identity in the special cell list is transferred as such (501) whereafter it is transferred transfer codes (522) which are differences (521) of two consecutive special cell identities in the special cell list. The special cell identities in the special cell list are advantageously arranged in the order of magnitude in the special cell list. Using the solution according to the invention it is possible to transfer the special cell information on the radio path by means of a single short message so that the transfer of special cell information can be carried out quickly without using a lot of the radio path's capacity in connection with call setup and handover.

Status Date: 2007-04-18

A system for subterranean termite detection, measuring, concentration, collection, marking, tracking and suppression is provided by deploying a family of devices in the soil peripheral to objects subject to termite infestation. Each device is fitted with a signal port in its dorsal surface for inspectors to examine, and lateral ingress/egress ports for termites to enter. Subterranean termites are attracted to the devices, which are constructed of a termite food material. When entering termites seal the signal port they produce a distinctive visual change that is observable by an inspector from a distance. This alerts the inspector to the presence of termite activity within the device. The signal port may have an interior reflector for reflecting light directed threat to indicate that the signal port has been sealed by termites. The signal port may also have a mesh disposed thereacross to prevent unwanted obstruction thereof. Lateral ingress/egress ports may have a cellulose plug preventing organisms other than subterranean termites from entering. The food material of a given device may optionally be fitted with one or more chambers that are vacant or that contain separate food materials. The food material of the devices, and/or of the optional chambers, may be impregnated with toxicants that poison, growth regulators that induce desirable changes in, and /or markers detectable in, termites that feed thereon. When the optional chambers are left vacant they may serve as aggregation cavities for termite collection purposes, in which case a removable ventral plate permits withdrawal of termites contained therein.

A ticket for and a method of conducting a probability game that can be used for instant lottery applications without the security risks normally associated with such games. Prior to generating the game tickets, the lottery or commercial entity decides what prizes they will offer and the frequency of those prizes appearing in the overall lottery. The total payout is determined based on standard statistical (probability) formulas. Based on this information, a computer is utilized to make a random selection of the number and/or symbol for each ticket that is that tickets winning number and the placement on the ticket of that winning number and/or symbol. Once the data is generated, an independent accounting firm verifies that each ticket does in fact contain a winner and that the placement of those winning numbers on the entire production run of tickets is without a pattern. When the verifications are completed satisfactorily, the tickets are printed and/or the data can be loaded to an on-line data base. The tickets consist of three separate parts, the game play portion containing numbers and symbols, a sequential ticket number and a validation number. The validation number is covered with an opaque, scratch off covering if the game is to be preprinted and sold in a continuous strip of tickets. If the game is used in an on-line game, the validation is not covered. The consumer can telephone to access the lottery computer and by using the telephone number pad to input the ticket data and the consumers number/symbol choice, learn the prize being offered with that particular ticket and whether or not the number/symbol selected is a winner. The consumer can then take the ticket to the ticket seller or other lottery center where the ticket can be verified as a winner by the seller and the prize paid.

An object of the present invention is obtaining a semiconductor film with uniform characteristics by improving irradiation variations of the semiconductor film. The irradiation variations are generated due to scanning while irradiating with a linear laser beam of the pulse emission. At a laser crystallization step of irradiating a semiconductor film with a laser light, a continuous light emission excimer laser emission device is used as a laser light source. For example, in a method of fabricating an active matrix type liquid crystal display device, a continuous light emission excimer laser beam is irradiated to a semiconductor film, which is processed to be a linear shape, while scanning in a vertical direction to the linear direction. Therefore, more uniform crystallization can be performed because irradiation marks can be avoided by a conventional pulse laser.

A method and system to verify the passage of one or more write commands sent from an originating location through a PCI bus system. An addressable data storage is located substantially at the end of the PCI bus system with respect to the originating location. A write command is sent by the originator subsequent to the one or more write commands, to a predetermined special end location address identifying the addressable storage. The command is accompanied by data comprising a predetermined special return address at the originating location. The PCI bus system transmits the write commands on a FIFO basis, so the one or more write commands precede the subsequently sent write command. Logic senses the subsequently sent write command, and responds to the command, sending a return echo write command to the predetermined special return address. The returning echo write command verifies the passage of the write commands and data through the PCI bus system. The predetermined special end location address is the key to identify the subsequently sent write command.

A STANDARD BLOCK architecture for integrated circuit (IC) design. The STANDARD BLOCK architecture provides a new level of abstraction with a granularity and regularity that is most appropriate for the physical implementation of complex, large scale deep-submicron IC designs. To this end, the STANDARD BLOCK architecture combines the advantages of standard-cell-based and functional-block-based architectures. The STANDARD BLOCK architecture includes a STANDARD BLOCK form that is physically constrained having one fixed or quantized dimension and one variable dimension that ranges between predefined limits. The STANDARD BLOCK granularity is larger than the standard cell granularity such that each STANDARD BLOCK includes a plurality of standard cells. In the STANDARD BLOCK architecture, each STANDARD BLOCK has flexible physical design properties. In this design style, the STANDARD BLOCKs are provided as general physical abstractions such that each STANDARD BLOCK is akin to a black box model with the majority of its internal design aspects invisible to the top-level assembly tool while selected design aspects remain visible. The global design aspects of each STANDARD BLOCK include its fundamental architectural and structural characteristics, including its physically constrained form, and its fundamental power, timing, clock and signal integrity properties. With the STANDARD BLOCK architecture, quantization of the STANDARD BLOCKs' form dimensions relative to IC dimensions can be substantially constant and scalable with increased IC complexity. Thus, STANDARD BLOCK architecture can be applied to any IC designs as well as any intellectual property (IP) designs.

Optical projection systems for the display of electronic images often suffer from degraded image quality due to color field registration errors caused by lateral chromatic aberration. Although most projection lenses are partially corrected for lateral chromatic aberration during the design process, the uncorrected residual aberration limits the imaging performance of many projection displays, especially when displaying text and graphics with single-pixel-wide features. Some embodiments of the invention correct color field registration errors due to lateral chromatic aberration in multiple-imager projection systems. Other embodiments of the invention correct radial distortion and keystone distortion in single-imager and multiple-imager projection displays. In some embodiments of the invention, the imager(s) pixel geometry is arranged to compensate for optical aberrations, which result from the optical system so as to achieve a corrected image.

A stacked plate chemical reactor in which simple plates, each incorporating no surface features other that an opening, are stacked together. When openings in adjacent plates are properly aligned, a fluid pathway is defined between inlet ports for each chemical reactant and an outlet port for a chemical product. In one embodiment of the invention, sixteen simple plates are stacked to provide a reactor incorporating three heat transfer fluid pathways, two reactant fluid pathways, one product fluid pathway, multiple mixing chambers, multiple reaction chambers, two reactant pretreatment heat exchangers, two reaction chamber heat exchangers, and multiple temperature sensor pathways. Precise dimensional control of the reactant fluid pathway height enables stacked laminar flow paths for the reactants to be achieved, allowing efficient and rapid diffusion mixing to occur. Because the simple plates incorporate no features other than openings, fabrication of such plates is easily achieved. Different reactor designs, having additional reactant pathways, more or fewer heat transfer fluid pathways, more or fewer heat exchangers, more or fewer mixing chambers, more of fewer reaction chambers, and more or fewer sensor pathways can readily be achieved by adding or removing plates from the stack, and or by changing the pattern and number of openings in the simple plates that are used. The simple plates can be field in the stack during use of the chemical reactor using pressure exerted on opposite outer simple plates of the stack, or can be permanently joined. A preferred material for the fabrication of the plates is stainless steel, although other materials such as glass, plastic, and other metals can alternatively be used, which are compatible with the selected reactants and the desired product.

The proliferation of uterine fibroid leiomyoma cells is inhibited by certain Fibroid Cell Growth Inhibitor (FGI) agents. The pharmacological doses of these FGI agents in the milieu of uterine fibroid cells can be made high enough to not only inhibit proliferation, but to also causes cell death. Non-invasive or minimally invasive, non-systemic delivery methods are used to deliver the FGI agent to the milieu of the target fibroid leiomyoma cell population, thereby avoiding the disadvantages and side effects of surgical and systemic hormonal therapy interventions in the treatment of uterine fibroids. The FGI agents are substrates that are normally present or are well tolerated in the human body. The efficacy of the FGI agents appears to be related to their ability to moderate the Protein Kinase C and Mitogen Activated Protein Kinase pathways. Specific FGI agents shown to be useful to inhibit growth or proliferation of uterine fibroid cells include: &agr;-tocopherol, &agr;-tocopherol succinate, and troglitazone. Delivery of the FGI agents to the milieu of the target uterine fibroid cells may be accomplished by intra-vaginal and in situ injection techniques already known in the art.

A method of fabricating a high energy radiation mask, such as a laser ablation mask for manufacturing inkjet printheads, includes a multi-stage evacuation process and/or a step of reducing the deposition rate of silicon dioxide during formation of a dielectric stack. When the multi-stage evacuation procedure is combined with the slower deposition rate of silicon dioxide, the resulting mask has a surprisingly low defect density. In the first embodiment, the evacuation procedure is initiated using a low-rate first evacuation connection. The relatively slow purging of a vacuum chamber in which the dielectric stack is subsequently formed controls turbulence and environmental changes that can generate contamination and water along the surface of the substrate on which the dielectric stack is formed. When a pressure setpoint is reached, a second roughing connection is activated to increase the speed of the procedure. The second connection has a higher maximum rate than the first connection. In the preferred embodiment, there is an overlap in the activations of the first and second connections. When another setpoint is reached, a high vacuum connection is activated in order to bring the vacuum chamber to a high vacuum condition for deposition of the dielectric stack. The dielectric stack includes alternating layers of higher refractive index material and low refractive index material. The low refractive index material is silicon dioxide that is deposited at a rate in the optimal range of 1.0 å/second to 3.0 å/second. Practical considerations dictate a range of 1.6 å/second to 2.4 å/second.

A material layer which contains nitrogen atoms is formed on a first wiring or at a side surface of a first wiring. When etching for forming a via hole is carried out, nitrogen atoms contained in the material layer bind with CF molecules, CF2 molecules, CF3 molecules and the like contained in an etching gas, and compounds thus formed adhere to a surface of a silicon dioxide layer at side walls and a bottom portion of a via hole. As a result, once the material layer is exposed during etching for forming a hole, thereafter, the etching rate decreases. Accordingly even if there is misalignment of a via hole pattern with respect to a first wiring pattern when the via hole pattern is formed by lithography, etching of the silicon dioxide layer does not proceed to an underlying silicon substrate. Thus, short circuits are not formed between the first wiring and the silicon substrate via a second wiring layer which is deposited later.

A surface acoustic wave device (e.g., filter or convolver) is designed to increase an electromechanical coupling factor K2 and is basically configured by a substrate, a buffer layer, a piezoelectric layer and an electrode layer. Herein, the substrate is made of a bulk material (e.g., SrTiO3), which allows growth of a perovskite compound crystal being expressed by a general chemical formula of SrZO3 (where Z denotes an element such as Zr and Sn whose valence is 4). The buffer layer is formed on the substrate and is made of the perovskite compound crystal (e.g., SrZrO3, SrSnO3), which has good lattice matching with KNbO3. The piezoelectric layer is made of a KNbO3 single crystal and is formed on the buffer layer with a thickness of 500 nm or so. The electrode layer is formed on or below the piezoelectric layer. An interdigital transducer consisting of input and output electrodes is formed by patterning using photolithography technique being effected on the electrode layer, which is made of a metal material (e.g., Al). In addition, it is possible to form a temperature stabilization layer between the piezoelectric layer and electrode layer. The temperature stabilization layer is made of a material (SiO2) having a temperature coefficient reverse to a temperature coefficient of the piezoelectric layer so as to ease distortion being caused to occur due to differences in thermal expansion between the piezoelectric layer and electrode layer. Incidentally, the temperature stabilization layer has a prescribed thickness, which is approximately 1000 nm.

The present invention relates to a fingerprint sensing device comprising a planar array of closely-spaced capacitive sense elements. When a finger is placed in close proximity to the sensing device, the capacitive sense elements measure a capacitance between the finger and a single capacitor plate in each sense element. This is accomplished by precharging each capacitor plate, and then using a known current source to remove a fixed amount of charge from each capacitor plate. The measured capacitance varies as a function of the distance between the capacitor plate and the finger surface. Thus, a capacitance measurement allows the distance between the capacitor plate and the finger surface to be determined. Distance measurements across the array of sense elements are combined to produce a representation of the pattern of ridges on the finger surface which comprise a fingerprint. After a fingerprint is acquired, the quality of the fingerprint is evaluated, and if necessary, a gain parameter for the sense elements is iteratively adjusted until a satisfactory fingerprint is acquired.

Pixel clock and beam scan timing of an acousto-optic scanner are controlled by an acoustic velocity-driven, phase locked loop containing an adjustable voltage controlled pixel clock generator, which is controlled by a detector that produces delayed and attenuated replica of the excitation waveform applied to an ATWL scanner used to scan a light beam across a workpiece. In a first embodiment of the invention, an end-of-cell transducer converts the pressure induced traveling lens into an electrical signal replica of the excitation input. In a second embodiment, an end-of-scan optical pick-off monitor is employed to detect the scanned optical spot as it crosses its field of view. Each pixel is spatially invariant to propagation velocity changes in the ATWL medium, so that as variations in temperature change the speed of the pressure-induced lens traveling from the excitation transducer to the end of the ATWL cell on each scan, the pixel clock is correspondingly slowed down or speeded up by the same proportional amount, to maintain registration in time and space.

Status Date: 2015-04-20

A radiation-image photographing apparatus is provided with a voltage controlling switch 52 for switching voltage which is applied from a power source 53 to a detector 10, a high-voltage generator 62 for supplying high voltage HV to a radiation source 61, and a control section 70 for controlling a light-source control section 40. When a generator switch 63a is on, the high-voltage generator 62 generates high voltage HV. The control section 70 senses that a signal S1 has gone low and makes a signal C2 high, whereby dc voltage is applied to the detector 10. After tp1 has elapsed since the signal C2 was made high, the control section 70 makes a signal C1 low, thereby causing the light-source control section 40 to be in a preexposure mode. After tp3 has elapsed since the emission of preexposure light P was started, the control section 70 makes a signal C3 high, thereby causing the radiation source 61 to emit radiation R. After te3 has elapsed since the emission of radiation R was started, the control section 70 causes the signal C2 to be in a high impedance state, thereby stopping the application of voltage to the detector 10.

The present invention provides a paging amplifier for a cellular phone, which includes an input/output terminal connected to an earphone microphone terminal of the cellular phone. An output terminal of the paging amplifier is connected to an external speaker. The paging amplifier includes a handset that has a microphone and a speaker, and a detector that detects whether the handset is in a predetermined position. A calling sound of the cellular phone is input to the paging amplifier through the earphone microphone terminal and the input/output terminal. The paging amplifier amplifies the input calling sound and outputs the amplified calling sound to the external speaker through the output terminal. The external speaker receives and broadcasts the amplified calling sound. When the handset is removed from the predetermined position, the detector detects the action and stops the calling sound. Since the paging amplifier for the cellular phone amplifies the calling sound of the cellular phone and outputs the amplified sound through the external speaker, the user does not miss hearing the calling sound. Further, since the calling sound stops when the handset is operated (removed from the predetermined position), usage of the paging amplifier is very convenient.

Status Date: 2015-04-20

A self-timed translation lookaside buffer (TLB) is disclosed that utilizes a two-level match scheme to trigger the evaluation of whether a match is achieved for a received virtual address within the TLB. The first level is referred to as the local match, and the second level is referred to as the global match. An entry of a TLB comprises groups of bits, with each group coupled to a separate local match line. Each of the local match lines of an entry is coupled to a global match line, which is initially set to a high voltage level and discharges to a low voltage level if any of the local match lines indicate a mismatch for their respective group. Accordingly, when the global match lines are evaluated, if the global match line has a high voltage level it indicates that the associated TLB entry matches the virtual address, otherwise the global match line indicates a mismatch for the entry. Multiple global match lines are evaluated to trigger a memory access for a matching entry. More specifically, in a preferred embodiment, a pair of neighboring global match lines are input to a NAND gate, the output of which triggers the evaluation of whether a match is achieved for either entry.

A system and method of implementing thereof that maps and condenses system control using reachable state control words is described. The system includes a control logic block, a look-up table which stores N-bit reachable state control words derived from an implementation description N-bit control signal, and a logic hardware block. The control logic block accesses the look-up table with a M-bit control word address. The accessed look-up table outputs a N-bit reachable state control word which is used to control the logic hardware block so as to simulate functions as defined by a user input description. A method for implementing the system is performed by synthesizing the user input description to generate an implementation description which describes a control model of the system in terms of a control logic block driving a logic hardware block with a N-bit control signal. The implementation description is analyzed to determine the reachable states of the N-bit control signal. A look-up table is created by storing N-bit reachable state control words corresponding to each reachable state of the N-bit control signal. A mapping function is determined between each reachable state control word stored in the look-up table and a M-bit control word address for accessing the look-up table. Finally, a control logic block is configured or programmed to implement the determined mapping function.

A method for developing re-usable software for the efficient verification of system-on-chip (SOC) integrated circuit designs. The verification software is used to generate and apply test cases to stimulate components of a SOC design (“cores”) in simulation; the results are observed and used to de-bug the design. The software is hierarchical, implementing a partition between upper-level test application code which generates test cases and verifies results, and low-level device driver code which interfaces with a core being simulated, to apply the test case generated by the upper-level code on a hardware level of operations. Test application and supporting low-level device driver pairs are used and re-used to test their corresponding component cores throughout the SOC development process, by creating higher-level test control programs which control selected combinations of the already-developed test application and device driver programs to test combinations of SOC components. The method provides for the efficient verification of SOC designs and, consequently, a reduced time-to-market for SOC products, because as the verification software is developed and stored, it becomes possible to test increasingly complex core combinations by creating relatively few high-level test programs which re-use already-existing lower-level software. Ultimately, the task of verifying a complex SOC design may be simplified to developing a single chip-specific test program which selects from already-existing test application, device driver and test control programs to perform a realistic test of a chip-specific combination of cores.

A scan data signal processor is disclosed for use with a laser scanning system having a plurality of different focal zones within which a laser scanning beam is scanned across one or more bar code symbols and an analog scan data signal is automatically produced. The scan data signal processor comprises a first and second derivative signal generation stages, a second-derivative zero-crossing detector, a real-time bar code element detector, and a control logic circuitry. The first derivative signal generation stage derives a first derivative signal from the analog scan data signal. The second derivative signal generation stage derives a second derivative signal from the first derivative signal. The second-derivative zero-crossing detector detects zero crossings in said second derivative signal. The real-time bar code element detector automatically detects the presence and absence of bar code element data encoded within said analog scan data signal. The control logic circuitry automatically activates the second-derivative zero-crossing detector in response to the detection of the presence of bar code element data encoded within said analog scan data signal, and automatically deactivates the second-derivative zero-crossing detector, in response to the detection of the absence of bar code element data encoded within the analog scan data signal. By virtue of the present invention, it is now possible to enable the detection of zero-crossings occurring in the second derivative of the analog scan data signals only when bar code element data has been detected, indicative that a bar code symbol has been scanned. This results in more accurate generation of digital output signals from the scan data signal processor.

The invention features devices and methods for the systemic delivery of fentanyl or a fentanyl congener (e.g., sufentanil) to treat pain. In the present invention, a drug formulation comprising fentanyl or a fentanyl congener is stored within a drug delivery device (e.g., contained in a reservoir or impregnated within a matrix within the controlled drug delivery device). The drug formulation comprises an amount of drug sufficient for treatment and is stable at body temperatures (i.e., no unacceptable degradation) for the entire pre-selected treatment period. The drug delivery devices store the drug formulation safely (e.g., without dose dumping), provide sufficient protection from bodily processes to prevent unacceptable degradation of the formulation, and release the drug formulation in a controlled fashion at a therapeutically effective rate to treat pain. In use, the drug delivery device is implanted in the subject's body at an implantation site, and the drug formulation is released from the drug delivery device to a delivery site. The delivery site may be the same as, near, or distant from the implantation site. Once released at the delivery site, the drug formulation enters the systemic circulation and is transported to the site of action in the body to modulate the pain response (e.g., the brain or other pain sensory location).

A method and apparatus thereof for fabricating an integrated circuit on a laminate having a gate electrode layer over a silicon dioxide layer. Detection of the gate etch endpoint signal is improved by maximizing the use of a faster etching dopant material (e.g., n-type dopant) and minimizing the use of a slower etching dopant material (e.g., p-type dopant) in the gate electrode layer. In one embodiment, a first portion of the gate electrode layer, substantially corresponding only to the location at which a gate is to be formed, is doped with the slower etching dopant material. The remaining portion of the gate electrode layer is doped with the faster etching dopant material; thus, more of the gate electrode layer is doped with the faster etching dopant material than with the slower etching dopant material. A gate mask is aligned over the gate electrode layer, and the unmasked portions of the gate electrode layer are removed using an etchant. The n-doped portions of gate electrode layer will etch away faster, and because the gate electrode layer is predominantly n-type, a strong and detectable endpoint signal will be induced when the etchant reaches the silicon dioxide layer.

An arrangement is disclosed for optically reading out the information from substrates having a multiplicity of individual samples, in particular for analyzing chemical and biological sample carriers. The arrangement presents a new possibility for optically reading out the information from matrix-type substrates having a multiplicity of individual samples which allows a fast read-out of a radiation which is influenced by the individual samples with a high degree of sensitivity. This possibility is achieved by the fact that, in the case of optically reading a matrix-type substrate having a multiplicity of metrically ordered pixels, the receiver that is provided is an individual receiver which has high sensitivity and a uniform receiver area, an electrooptical matrix and also an imaging optical system are present, each substrate pixel being assigned to a matrix pixel region by the imaging optical system, and the matrix can be driven in such a way that matrix regions which allow exclusively the feeding of radiation from a substrate pixel to the receiver can be switched separately. Radiation quantities from in each case at least one substrate pixel successively impinging on the receiver over a suitably chosen time interval. The result is that it is possible to evaluate a series of measured radiation quantities from selected sequences of substrate pixels at the output of the receiver.

A computer-driven file management technique is applied to a distributed file system with multiple storage “aggregates” to improve file distribution, user access, server workload, and the like. For a first aggregate, a recognition module analyzes file contents of all aggregates, plans a set of physical data movement operations to configure data stored upon a first one of the aggregates according to certain prescribed “goals,” and buffers the planned physical data movement operations. The planned set of physical data movement operations constitute a “virtual” data move. The reviewing, planning, and buffering operations are repeated for all remaining aggregates in the distributed file system. However, each repeated reviewing operation considers the file contents of the aggregates as if all previous virtual data moves had actually been performed. Asynchronously with the storage analysis and reconfiguration planning, the system processes the action buffer. Namely, the system reads buffer contents according to a prescribed order, consults predetermined action “rules,” and then carries out the physical data moves in accordance with the action rules. The action rules may specify desirable hours to move data or avoid moving data, for example.

The present invention is an image recording method and apparatus for recording an image represented by at least two sets of image data separated by colors. Based on the image data, images corresponding to the image data are each recorded on different sections of photosensitive material moving in a sub-scan direction, while the photosensitive materials subjected to main scan by a plurality of light beams. Thereafter, the sections of the photosensitive material are superimposed over one another to produce the final image. Relative positions of the images on each section of photosensitive material are provided to substantially coincide with each other by setting a selected number of blank raster lines in a first main scan for each section of the photosensitive material. As a result, an amount of displacement of each of images on the photosensitive materials is reduced when the sections of photosensitive material are superimposed and aligned with one another to produce the final image. Preferably a blade is used for cutting the photosensitive material into different sections.

A bar code (10) has primary information (46,48,50,51) encoded in one direction (e.g., horizontally) and secondary information (13,21,36) encoded in another direction (e.g., vertically) in single (11) or multiple tracks (35) in selected ones of the vertical bars (11) of a bar code (10). Using a non-linear, variable amplitude scanner, all of the primary bars are scanned in the one direction to obtain all of the primary information and all of those vertical bars having secondary information are scanned in the other direction to obtain all of the secondary information. The one direction which is perpendicular to the vertical primary bars (11), is determined by first rotating the scan path axis (86,87) until both start (46) and end (48) code bars are read thereby placing the scan path entirely within the total bar code, and, then, further rotating the scan path (88,89) to determine the direction of the minimum crossing width (Lsc 80) of the total bar code (10). Secondary information is scanned in planes orthogonal to the one direction after those vertical bars (11) having such information are first identified and selected. In a preferred embodiment, the decoded secondary information may be used to control selected station process operations for selected products in a continuous manufacturing assembly line.

An input video signal is distributed to two links. The distributed video signals are coded by encoders in a spacewise or timewise shifted manner, and then, are transmitted over the transmission links. On a receiving side, the video signals are decoded by decoders, respectively. An averaging processor determines an average of the video signals per pixel, and then, outputs it. A data selector selects an output from the averaging processor when the plural links are operated normally; to the contrary, it selects a decoded output on the normal link in the case where an accident occurs in any one of the plural links. Specific methods for shifting the video signals spacewise or timewise include: a method for shifting a timing of intra-frame coding; a method for shifting the video signals on the links by several pixels or lines at least one of upward, downward, rightward and leftward; a method for disposing a sampling conversion filter in at least one of the links; and the like. According to the present invention, it is possible to provide a video transmission system using the plural links in which the transmission capacity of a backup link can be effectively used while high reliability of transmission can be ensured.

The present invention relates to a method in a cellular mobile communication system for transmitting Pages, and such a system. The cells of the system are subdivided into two classes. To which class a cell is assigned is decided by its capacity to transmit Pages or by the amount of Page responses received within the cells. When paging a mobile station, the Page is first transmitted in the cells of the first class. If no response is received to that Page, the Page is transmitted also in the cells of the second class. An advantage is that there will be fewer Pages congested due to lack of capacity for transmission. Transmitted Pages in the cells of the second class are primarily transmitted to mobile stations that are really present within those cells. Thereby the probability increases that all mobile stations will be reached by Pages intended for them.

A shared memory multiprocessor (SMP) has efficient access to a main memory included in a particular node and a management of partitions that include the nodes. In correspondence with each page of main memory included in a node, a bit stored in a register indicates if the page has been accessed from any other node. In a case where the bit is “0”, a cache coherent command to be sent to the other nodes is not transmitted. The bit is reset by software at the time of initialization and memory allocation, and it is set by hardware when the page of the main memory is accessed from any other node. In a case where the interior of an SMP is divided into partitions, the main memory of each node is divided into local and shared areas, for which respectively separate addresses can be designated. In each node, the configuration information items of the shared area and the local area are stored in registers. The command of access to the shared area is multicast to all of the nodes, whereas the command is multicast only to the nodes within the corresponding partition when the local area is accessed.

A casing scraper for cleaning the internal wall of a tube 26 such as a well casing has at least three, rigidly connected, axially and angularly spaced scraper bodies 12, 14, 16 each with a scraping surface 13, 15, 17. The radial dimension of the scraper at each scraping surface is slightly greater than the internal radius of the tube which it will scrape. When the scraper is fully inserted in the tube bore, the scraping surfaces are deflected inwardly and the axial connection 20, 22 between the bodies is accordingly elastically deformed. Th energy stored through this elastic deformation produces a radially outwardly acting force which presses the scraping surfaces 13, 15, 17 against the wall of the tube 26. The eccentric arrangement of the scraping surfaces, and the axial spacing between the surfaces causes the parts of the scraper connecting the scraping surfaces to be placed in bending when the scraper is in place within the tube. The bending of the intermediate parts between the scraping surfaces produces a stress which urges the scraping surfaces into contact with the tube internal surface.

Improved apparatus are diclosed for stepwise, layer by layer fabrication of three-dimensional objects by irradiation of radiation-curable materials, in which the critical steps of fast and efficient deposition of thin, flat layers of material covered with a radiation-transmitting film, as well as careful separation of the film upon irradiation, are achieved by using a reciprocating carriage that during its motion changes the elevation of the film. When the carriage is moving in one direction, the film is being laid down forming a layer, and when upon irradiation the carriage is returning, it is peeling the film off without distorting the formed layer. Improved apparatus are provided that build the whole object on an open platform without using a container or form each layer above container.

The present invention describes a catheter suitable for introduction into a tubular tissue for dissolving blockages in such tissue. The catheter is particularly useful for removing thrombi within blood vessels. In accordance with the preferred embodiments, a combination of vibrating motion and injection of a lysing agent is utilized to break up blockages in vessels. The vessels may be veins, arteries, ducts, intestines, or any lumen within the body that may become blocked from the material that flows through it. As a particular example, dissolution of vascular thrombi facilitated by advancing a catheter through the occluded vessel, the catheter causing a vibrating, stirring action in and around the thrombus usually in combination with the dispensing of a thrombolytic agent such as urokinase into the thrombus. The catheter has an inflatable or expandable member near the distal tip which, when inflated or expanded, prevents the passage of dislodged thrombus around the catheter. The dislodged portions of thrombus are directed through a perfusion channel in the catheter, where they are removed by filtration means housed within the perfusion channel before the blood exists the tip of the catheter. Catheters that allow both low frequency (1-100 Hz) vibratory motion and delivery of such agents to a blockage and a method for using such catheters are disclosed.

A method for the controlled nanometer-scale deposition of molecules on a surface, by means of coherently controlled optical focusing. The coherent control is conveniently performed by inducing a linear superposition of molecular bound states, by means of electromagnetic fields supplied by an applied laser beam. The optical focusing is conveniently performed by passing a beam of such suitably prepared molecules through another electromagnetic field supplied by a standing wave induced by two interacting laser beams. Altering the characteristics of the laser beams alters the forces operating on the molecules, thus directing them to the desired position on the surface. Selection of the frequencies, intensities, and relative phases of the electromagnetic fields, as well as the geometry of the interaction between the molecular beam and the electromagnetic fields, enables deposition of aperiodic molecular patterns on the surface with a resolution of 10 to 15 nanometers. Such nanoscale focusing of molecules by coherent light can be used for executing nanometric molecular lithographic processes.

An optical heterodyne detection system includes an input signal and a local oscillator signal that are combined in an optical coupler and output as a first beam and a second beam. A polarizing beam splitter is optically connected to the optical coupler in order to receive the first beam and the second beam. The polarizing beam splitter includes four outputs for outputting four beams to four photodetectors including two polarized portions of the first beam and two polarized portions of the second beam. The four photodetectors generate four electrical signals in response to respective ones of the four beams. The four electrical signals are transmitted to a processor and processed to provide an output response that is independent of the polarization state of the original input signal and in which the intensity noise has been suppressed. Processing of the electrical signals to suppress the intensity noise involves canceling the intensity noise component of similarly polarized beams by subtracting the similarly polarized beams. Processing of the electrical signals to provide polarization independence involves squaring the values generated from the two subtraction operations, low pass filtering the values generated from the two squaring operations, and then adding the values generated from the two filtering operations.

In a system for producing an animation on a computer by use of keyframes, shapes are drawn on the basis of the positions of vertices designated by a user without direct manipulation of control points for Bézier curve so that there is little problem even in the case where a line drawing of each handwritten keyframe is broken discontinuously. To this end, Bézier curves are automatically generated to draw shapes by fetching a plurality of keyframes written on paper into a computer and then setting vertices of only first one of the keyframes. On this occasion, an optimum path connecting the position of each of the set vertices to the current cursor position is calculated. The path is approximated by a cubic equation. A Bézier curve is defined on the basis of comparison of coefficients of respective terms in the equation with coefficients in the Bézier curve. For each of keyframes after the first keyframe, control points for Bézier curve are re-calculated to reshape shapes by moving vertices of the previously drawn shapes and by dragging the neighborhood of the contour of the keyframe.

Average fringe contrast is determined by PSI measurements at each step of relatively large translations of the reference optics and mirror of a white-light Linnik interference objective and the resulting data are used to minimize the OPD between the reference and test beam paths of the instrument. Utilizing the same algorithms used in the art to perform conventional vertical scanning interferometry, the position of minimum OPD is determined by finding the position of maximum average fringe contrast. Furthermore, by automating the system with a precise translation mechanism, operator-to-operator variations are completely eliminated and the precision of the process of OPD minimization is greatly improved. In another embodiment of the invention, the optimal focal position of the reference mirror is found at the same time by calculating the average lateral variation of fringe contrast as a function of OPD and focal position. The optimal OPD and focal position correspond to the maximum average lateral variation of fringe contrast in the resulting three-dimensional space.

A compression technique, for use in a network environment, compresses transform data to improve transmission rates in low bandwidth applications. The source data is decomposed into transform data that consists of spatially related coefficients. In a client-server environment, a client issues a request, which defines a block of the coefficients and at least one quantization value, for source data. In response to the client request, the server extracts transform data defined by the request. The transform data is quantized, in accordance with the quantization value, and is compressed to generate compressed data. The server transfers the compressed data to the client. The client decompresses the compressed data to obtain quantized data, and de-quantizes the quantized data to recover the transform data. The client then reconstructs the original source data from the transform data. Techniques for transmitting to the client incremental data, for use in conjunction with cached data, is disclosed.

Status Date: 2015-05-25

To provide a self-diagnosing apparatus for a refrigerator which self-diagnoses an operation condition and advises a user of an appropriate improvement action if there is an abnormal. First, a detector such as an internal temperature sensor detects a plurality of condition-indicative quantities with respect to the refrigerator, and the condition-indicative quantities are stored in a memory part for a predetermined period. A diagnostic device such as a diagnosis calculation value judging part compares the condition-indicative quantities or a diagnosis calculation value which is calculated based on the condition-indicative quantities with a predetermined threshold value, and judges whether the operation condition of the refrigerator is normal or abnormal based on a result of the comparison. At this stage, if the condition-indicative quantities covering the predetermined past period which are stored in the memory are used as the condition-indicative quantities for the diagnosis, it is possible to accurately diagnose without influence of a condition-indicative quantity which suddenly appears. When it is judged that there is an abnormal condition as a result of the diagnosis, an improvement action which is preliminary determined for the abnormal condition is selected. The selected action is displayed visually or as a sound by an outputting device such as a sound emitter. Where a re-diagnosis is executed after a predetermined time since the abovementioned diagnosis and the outputting device output the improvement action based on a result of the re-diagnosis, it is possible to diagnose with an enhanced reliability.

An illumination method and apparatus for machine-vision systems, including a ring-light source (e.g., LEDs arranged in one or more circular rows), and a reflective-ring focusing element. The illumination source exhibits multi-directional ring-illumination properties which are useful for illumination of small components (which are being inspected or measured) without unwanted shadows. One embodiment provides a darkfield illumination system. One embodiment of the present invention uses a strobed (or pulsed) power supply to drive the LEDs. Yet another embodiment of the present invention uses a xenon strobe ring-light source and a backplane slit in place of the row of LEDs 25. In one such xenon strobe embodiment, a color filter, is also placed in series with the light path in order to obtain a monochromatic light. While xenon flashtube light sources tend to exhibit a five percent (5%) flash-to-flash variation in intensity which makes accurate measurements of certain characteristics difficult, they are useful in certain cases where intense white, or especially ultraviolet, light is desired. Strobed LEDs provide very little flash-to-flash variation in intensity. The compact ring-light generator has little, if any, shadowing. The present invention also provides an inexpensive apparatus and method for changing the light-source-to-optical-axis angle.

A thermal barrier coating system and a method for forming the coating system on an article designed for use in a hostile thermal environment. The method is particularly directed to a coating system that includes a plasma-sprayed MCrAlY bond coat on which a thermal-insulating APS ceramic layer is deposited, in which the oxidation resistance of the bond coat and the spallation resistance of the ceramic layer are substantially increased by vapor phase aluminizing the bond coat. The bond coat is deposited to have a surface area ratio of at least 1.4 and a surface roughness of at least 300 &mgr;inch Ra in order to promote the adhesion of the ceramic layer. The bond coat is then overcoat aluminized using a vapor phase process that does not alter the surface area ratio of the bond coat. This process is carried out at relatively low temperatures that promote inward diffusion of aluminum relative to outward diffusion of the bond coat constituents, particularly nickel and other refractory elements. The process conditions also provide sufficient vapor phase activity at the surface of the bond coat that promote aluminum atomic movement through the bond coat.

A method of preventing or at least reducing the likelihood of bridging between adjacent micro-scale polycrystalline structures, and particularly to reducing electrical shorting between adjacent metallization lines of a microcircuit. The method generally entails forming a multilayer structure that comprises a polycrystalline layer and at least one constraining layer, and then patterning the multilayer structure to yield a first line and a second line that is narrower in width than the first line. The first line has a patterned edge that is spaced apart from a patterned edge of the second line, so that the first and second lines are electrically insulated from each other. One or more features associated with the first line are then formed that prevent bridging between the first and second lines if excessive lateral grain growth subsequently occurs along the patterned edge of the first line. Suitable features include patterning the multilayer structure to form a dummy line between and spaced apart from the first and second lines, patterning holes near the patterned edge of the first line, forming the patterned edge of the first line to have teeth that project toward the second line and are closer to the second line than the remainder of the patterned edge between the teeth, and forming the patterned edge of the first line to be stepped so that the first line has corner regions at opposite ends of the patterned edge that are closer to the second line than the remainder of the patterned edge between the corner regions. The invention also encompasses multilayer structures formed in accordance with the method.

High purity protein A is recovered from protein A preparations by passing a protein A preparation over an ion exchange column so that protein A will bind to a cation exchange resin. The loaded column is washed with a wash buffer solution having about the same pH as the protein A preparation and an increased mineral salt concentration to elute certain impurities but not the protein A. The protein A is eluted from the washed column by eluting the column with an elution buffer solution having a pH higher than the wash buffer solution and mineral salt concentration substantially no higher than the wash buffer solution. The protein A can be easily recovered from protein A preparations that do not use any human or animal components. The protein A purified by the invention is suitable for all common uses of protein A, but is especially well-suited for human therapeutic applications.

Switches and joysticks comprise user-moveable two position and multi position switches, including simple on/off and variable switches such as dimmers. The switches operate on the principle of detecting the position of a user-grippable switch arm, a portion of which bears on a pressure-sensitive pad. The pad is a deformable material which detects and localizes pressure against the pad, by transmitting into the pad matrix a wave energy such as light, and detecting the intensity of same. As the pad is locally compressed, intensity of the wave energy increases in the region around the compression. The position of a switch arm may thus be detected, and the information transmitted to a central processing unit, for further processing.

A method and apparatus for utilizing temporal prediction and motion compensated prediction to accomplish multiple description video coding is disclosed. An encoder receives a sequence of video frames and divides each frame into non-overlapping macroblocks. Each macroblock is then encoded using either an intraframe mode (I-mode) or a prediction mode (P-mode) technique. Both the I-mode and the P-mode encoding techniques produce an output for each of n channels used to transmit the encoded video data to a decoder. The P-mode technique generates at least n+1 prediction error signals for each macroblock. One of the at least n+1 P-mode prediction error signals is encoded such that it may be utilized to reconstruct the original sequence of video frames regardless of the number of channels received by the decoder. A component of the one of the at least n+1 P-mode prediction error signals is sent on each of the n channels. Each of the remaining at least n+1 P-mode prediction error signals is sent on a separate one of the n channels (along with the above mentioned component). These remaining at least n+1 P-mode prediction error signals are encoded such that, when combined with the component of the one P-mode prediction error signal which was sent on the same channel, a reasonably good reconstruction of the original sequence of video frames may be obtained if the number of received channels is between 1 and n−1.

Subsearch, where a satisfiability algorithm searches through the original theory for ground clauses that satisfy some numeric property, is represented in terms of S(C,P,u,s), the set of ground instances of C that have u literals unvalued by P and s literals satisfied by the assignments in P. This representation allows an intelligent search to be performed to answer subsearch problems posed in terms of S(C,P,u,s). Intelligent Subsearch uses truth value assignments to atoms to eliminate sets of bindings to universally quantified variables within a quantified clausal constraint; the bindings being eliminated because the bindings cannot satisfy a specific statement. Intelligent subsearch backtracks away from poor choices in the search for bindings to variables within the quantified clauses. In typical uses, intelligent subsearch can reduce the time of the checking problem from O(DU) to O(D&agr;U) for some &agr;<1.

A bandwidth conserving queue manager for a FIFO buffer is provided, preferably on an ASIC chip and preferably including separate DRAM storage that maintains a FIFO queue which can extend beyond the data storage space of the FIFO buffer to provide additional data storage space as needed. FIFO buffers are used on the ASIC chip to store and retrieve multiple queue entries. As long as the total size of the queue does not exceed the storage available in the buffers, no additional data storage is needed. However, when some predetermined amount of the buffer storage space in the FIFO buffers is exceeded, data are written to and read from the additional data storage, and preferably in packets which are of optimum size for maintaining peak performance of the data storage device and which are written to the data storage device in such a way that they are queued in a first-in, first-out (FIFO) sequence of addresses. Preferably, the data are written to and are read from the DRAM in burst mode.

Three mechanical locks are part of a mechanism for adjusting and dumping a vehicle seat. A master mechanical lock attaches to the seat back. When it is unlocked, depending on the condition of the other locks, one can adjust or dump the seat. A dumping mechanical lock also attaches to the seat back through an intermediary of a slave mechanical lock. When the dumping mechanical lock is unlocked, a connection to the master mechanical lock also opens that lock to allow the seat back to dump. When one unlocks just the master mechanical lock, a connection between that lock and the slave lock unlocks the slave lock. When that lock is unlocked, one can adjust the distance of dumping mechanical lock to the seat back. Because the slave lock remains locked during dumping, the distance between the dumping mechanical lock and the seat back remains constant after dumping. A latch mechanism keeps the dumping lock unlocked until the dumping lock returns to a predetermined position. A connection between the master and dumping locks keeps the master lock unlocked as long as the latch mechanism keeps the dumping lock unlocked.

An improved method for the treatment of melanoma and skin diseases which utilizes a zinc chloride fixative mixture is provided. The active ingredients of the fixative mixture include zinc chloride (a deeply penetrating, tissue killing histologic preservative), and the anti-cancer plant alkaloids sanguinarine and chelerythrine. Zinc chloride allows the surgeon to perform a complete conventional surgical excision around and below a melanomatous tumor through painless, bloodless dead tissue, and because the microscopic structures are fixed in place by the zinc chloride, the excised tissue can be examined by a pathologist to confirm complete excision and clearance of the melanoma. Although zinc chloride fixative paste has been shown to be an effective treatment for human skin cancer and melanoma, this treatment has been overlooked by the medical community. The paste is difficult to maintain and complicated to apply to the affected skin. This invention allows the active ingredients of zinc chloride fixative paste to be effectively administered to the skin by providing single-use dose specific storage, application, dressing, and administration systems needed to facilitate the use of topical zinc chloride mixtures and/or zinc chloride pastes in the treatment of melanoma and other skin diseases. Enhanced zinc chloride mixture formulations are described.

A method of manufacturing a multi-layer, composite footwear upper having a three-dimensional geometry includes the steps of forming a substantially planar composite sheet from two or more layers, heating the composite sheet, and compression molding the composite sheet into the three-dimensional geometry of the footwear upper. The composite sheet is formed by laminating a first layer of thermoplastic foam to a second layer of thermoplastic urethane (TPU), preferably in the form of a TPU film. A third layer of mesh fabric can be interposed between the first and second layers. The composite sheet is compressed after heating in a mold cavity to achieve the desired three-dimensional geometry. The composite sheet can be compression molded into separate sections which are assembled after molding to form the footwear upper. Alternatively, the composite sheet can be compression molded into a seamless, unitary footwear upper that requires minimal, if any, assembly for completion. The multi-layer composite upper can be applied to a sole to form performance footwear suitable for use in a wide range of conditions.

The Print Ready File is compiled and all operations on the file can be completed via reference to the information contained therein. A state flag is associated with each element of the file, the flag having states such as preview, print, both, or none. The file is stored on an asset management file server. The file (unchanged) may be previewed or printed using internal flags and logic built-in to the PostScript language. A batcher service batches print jobs. A plater service accepts the Print Ready Files and outputs a plate file to a print vendor's ordering system. Over the Internet the plate file is sent to a vendor computer. The plate file is sent to a raster image processor (RIP) which outputs a bitmap to be printed. Included within the system is a trapping subsystem. A client application requests trapping of a file and pulls trapping parameters from an image logic information database. The client sends the parameters along with input and output files to a gateway service. The gateway service places the job in a queue which is monitored by a processor service. The processor service hands the job off to a hierarchy of processing services. A trapping module (with hardcoded parameters) executes the software application Trapwise to perform a trap of the file and outputs the result.

A system and method operates with a document collection in which documents are represented as normalized document vectors. The document vector space is partitioned into a set of disjoint clusters and a concept vector is computed for each partition, the concept vector comprising the mean vector of all the documents in each partition. Documents are then reassigned to the cluster having their closest concept vector, and a new set of concept vectors for the new partitioning is computed. From an initial partitioning, the concept vectors are iteratively calculated to a stopping threshold value, leaving a concept vector subspace of the document vectors. The documents can then be projected onto the concept vector subspace to be represented as a linear combination of the concept vectors, thereby reducing the dimensionality of the document space. A search query can be received for the content of text documents and a search can then be performed on the projected document vectors to identify text documents that correspond to the search query.

Status Date: 2011-06-13

A process for forming an etch mask having a discontinuous regular pattern utilizes beads, each of which has a substantially unetchable core covered by a removable spacer coating. Beads which have a core and a spacer coating are dispensed as a hexagonally-packed monolayer onto a thermo-adhesive layer, which is on a target layer. The beads are kept in place by a bead confinement wall. Following a vibrational step which facilitates hexagonal packing of the beads, the resultant assembly is heated so that the beads adhere to the adhesive layer. Excess beads are then discarded. Spacer shell material is then removed from each of the beads, leaving core etch masks. The core-masked target layer is then plasma etched to form a column of target material directly beneath each core. The cores and any spacer material underneath the cores are removed. The resulting circular island of target material may be used as an etch mask during wet isotropic etching of an underlying layer. Such a combination of plasma etching using the bead cores as a primary mask and a wet etch using the islands formed by the plasma etch as a secondary mask may be used to form micropoint cathode emitter tips in an underlying conductive or semiconductive layer.

Described is an image tracking device that includes an array of light-sensitive elements. A row and a plurality of columns define the array, and an intersection of the row with one of the columns defines a cell frame. The row and columns are arranged in non-rectilinear geometry. Each cell frame has a frame area, and one of the light-sensitive elements is disposed in each cell frame. Each light sensitive element has an active area that generates an electrical signal indicative of light from a portion of an image that is incident within the cell frame containing that element. A fill-factor is defined by the ratio of the active area in a cell frame to the frame area of that cell frame. Two-dimensional motion of an image that is incident on the array can be tracked by whole-frame correlations between successive images from the array thereby eliminating the need for localized correlations throughout the array and subsequent curvilinear transformation algorithms to convert motion data throughout the image from an otherwise rectilinear array into data that is representative of the actual two-dimensional motion of the object. Geometric distortions produced by an optical system that focuses an image on the array or by curved object surfaces can be corrected or compensated for by arranging the array in a non-rectilinear shape that matches the geometric distortion in the image. For example, the array can have a pincushion shape or a barrel shape to compensate for pincushion distortion or barrel distortion respectively. Moreover, the flexible sizing of the active area in each cell frame can be used to compensate for fixed illumination gradients in an image incident on the array. The pitch of cell frames can be made to effect an image resolution that is dependent on position within the array. Active area shapes and positions within cell frames can be varied to reduce errors caused by aliasing.

A medical device for positioning a patient correctly in the sitting position when performing spinals or epidurals. The medical device is wedge shaped and inflexible. The device can have handles adjacent to the front wall of the wedge or can be used without the handles.The device is used by first placing it on an elevated surface, then having a patient sit on the device so that the patient's knees flex at the front and upper juncture of the device. The patient is then instructed to sit upright. By sitting upright, the pelvis will rotate backwards thereby promoting flexion of the lumbar/thoracic spine. On the medical device with handles, the flexion of the lumbar/thoracic spine can be augmented by having the patient push upward, palms up, on the handles. The upward pushing forces will force the lumbar spine posteriorly and further increase thoracic/lumbar flexion. Then either inserting the tip of a spinal needle into the patient's spinal space or inserting the tip of an epidural needle into the patient's epidural space.

Electric power is stored in a flywheel assembly, from a dc power buss, and supplied to the buss, through electronics associated with a motor/generator, its rotor integral with a flywheel supported by magnetic bearings. The power is reciprocally converted by the motor/generator, controlled by current in its polyphase stator windings, between electricity and kinetic energy. The flywheel and rotor assembly spins around a vertical axis. The rotor contains radial-field permanent magnets attached to supporting outer annular high-permeability steel, attached to inner annular steel. This completes a path for the magnets' field, which interacts with current in the stator windings, to produce torque between the rotor and the stator. Polyphase sinusoidal currents in the stator windings are controlled by the associated electronics, responsive to respective rotation angle sensors and the dc power buss voltage, with override control responsive to flywheel rotation speed, axial and radial position sensors, and operator settings. During normal operation, the flywheel assembly is levitated by axial attraction of its annular high-permeability poles near its top, to a fixed annular permanent magnet and high-permeability poles above it. The stator windings and non-rotating parts are affixed to a sealed and evacuated stationary flywheel enclosure. The flywheel assembly is released by mechanical backup bearings at startup, which then normally remain disengaged until shutdown. During normal operation, the flywheel assembly is levitated by the axial magnetic field, which also provides inherently stable centering. Axial position stability, and continuous axial position adjustment to seek and maintain axial position where force due to the permanent magnet is equal to levitated weight, is provided by a cooperative annular concentric coil whose current is controlled by an axial servo responsive to an axial position sensor. The coil adjusts strength of the magnetic field between the fixed and rotating poles, and thereby dynamically adjusts and stabilizes lift force. A coil current time-integral is combined with axial position feedback, so that average current is continuously adjusted to zero, by axial position adjustment. Radial electromagnets damp flywheel swirling at resonant vibration frequencies, stabilize its spin axis attitude at spin speeds too low for effective gyro stabilization, and constrain radial position during possible earth tremors. At normal spin rates, with the spin-axis at the rotor assembly center of mass, spin-axis verticality is stabilized by gyroscopics and leveled by gravity.

The present invention provides a method and apparatus using a gas concentration sensor for accurately controlling an air fuel ratio in an internal combustion engine, featuring in that before the fuel-vaporized gas purged from the canister enters into the intake manifold whereat the sensor detects the gas concentration of the purged gas, the sensor is adjusted so as to adjust a zero point (or zero output level) of the sensor output. In step 100 of FIG. 7, a judgment is made as to whether the flow rate of air reaches a predetermined level. In step 110, processing for zero-point correction of the gas concentration sensor is performed. Specifically, in a state in which the purge valve 17 is closed, concentration of purge gas is measured by use of the gas concentration sensor 4, and a sensor output S1 at that time is obtained. Subsequently, the sensor output S1 is compared with a correct sensor output S0 in order to obtain a difference &Dgr;S therebetween. Accordingly, during subsequent gas concentration measurement, a value S3 obtained through subtraction of the difference &Dgr;S from an obtained sensor output S2 is used as a correct sensor output. In step 120, a supply amount of purge gas, i.e., a concentration of the purge gas to be supplied is obtained. In subsequent step 130, the purge valve 17 is driven in order to supply purge gas to the intake pipe 2 in a required amount (A%).

After an underlying layer, made of a single crystal metal material, has been formed on a semiconductor layer, part or all of the underlying layer is changed into a metal oxide layer by supplying oxygen thereto from above the underlying layer. Then, a ferroelectric or high-dielectric-constant film is further formed on the metal oxide layer. Since the film made of a metal material is formed on the semiconductor layer, a silicon dioxide film or the like is not formed easily. Thus, a dielectric film, which includes an underlying layer with a high dielectric constant and has a large capacitance per unit area, can be obtained. Various defects such as interface states in the semiconductor layer can also be reduced advantageously if these process steps are performed after a thermal oxide film has been formed on the semiconductor layer.

An optical disk signal processing apparatus retains compatibility with the conventional continuous servo recording technique, and reduces the amount of noise included in a signal played back from the optical disk without the need to decrease the size of the area for recording data, resulting in a drastically increased signal-to-noise ratio. The optical disk signal processing apparatus has a light source, an optical system for leading a light beam generated by the light source, an optical device for converging the light beam output by the optical system and applying the converged beam to the rotating optical disk, a signal detecting optical system for detecting a signal reflected by the rotating disk through the optical device, and a light detecting instrument for converting light produced by the signal detecting optical system into an electrical signal and a data detecting circuit. The intensity of the beam radiated by the light source is modulated by a modulation circuit in synchronism with data detection timing so that a playback signal having an improved signal-to-noise ratio can be obtained by integrating a product of a response waveform signal generated by a light beam reflected from an information mark and a light-intensity modulating signal over a fixed period of time.

A data compression assembly has several data-compression channels (DCC). The data-compression channels may be, for example, encoders which encode different programs in accordance with an MPEG standard. A data-compression channel comprises a data compressor (CMP) and a buffer-memory space (BUF). The data compressor compresses input data (D) so as to obtain compressed data (Dc). The buffer-memory space temporarily stores the compressed data and provides the compressed data in the form of an output data stream (DS).Indications (IND) of compressed-data quality (Q[Dc]) versus extent of compression (E[CMP]) are established for respective data-compression channels. A total output bit rate (Rtot) is partitioned over respective output data streams in dependence on these indications. The extent of compression in respective data-compression channels is controlled individually on the basis of output data stream bit rate (R) and amount of compressed data (F) stored in the buffer memory space. This allows a substantially constant quality ratio between the compressed data from respective data-compression channels as well as a substantially constant quality of the compressed data from an individual data-compression channel.

A receiver and a phase extraction circuit are capable of demodulating at high resolution if the sampling frequency is close to the frequency of received signal. In the phase extraction circuit, the received signal modulated in phase is sampled when lowered to an intermediate frequency. When the sampling frequency at this time is selected around the intermediate frequency, a continuous portion appears in one position of the sampling data row. The position of the continuous portion is determined by the phase of the received signal, and therefore a one-to-one correspondence table of the continuous position and phase of received signal is prepared. By detecting the continuous position, the phase information can be obtained from the table. As a result, it is possible to demodulate directly at the intermediate frequency, and therefore the circuit scale is substantially simplified, the number of parts is curtailed, and the size is reduced.

A calibration procedure for correcting two port frequency measurements. Calibration standards are initially connected to port one of a network analyzer and individually measured. This process is repeated with port two of the analyzer. A jumper which is used to bridge ports one and two is then connected to port one. At the far end of the jumper, three references are sequentially connected and the combination of the jumper and the terminations are measured. The raw data measured thus far is then processed to extract the two port electrical parameters of the jumper. The measured jumper is then bridged between ports one and two, and a series of measurements are made. Using the known electrical characteristics of the jumper, an intervening network is completely characterized and the measured SM and actual SA parameters of any device to be tested are relayed.

Given an input sequence of data, a motif is a repeating pattern. The data could be a sequence of characters or sets of characters or even real values. In the first two cases, the number of motifs could potentially be exponential in the size of the input sequence and in the third case there could be uncountably infinite number of motifs. By suitably defining the notion of maximality and redundancy for any sequence with n characters, there exists only a linear (or no more than 3n) number of special motifs and every other motif can be generated from these irredundant motifs.

This invention provides methods, apparatus, system, and article of manufacture which solve the problem of mismatch between the keywords employed by a user in making a query and those assigned by the manual or automatic classification system stored in the system's keyword index. The system records the initial keyword(s) input by the user and holds them until the user is either satisfied or gives up. If in a query session the user is satisfied with the object(s) retrieved from the repository, the system associates the initial keywords(s) with the retrieved object(s). This facilitates the object's retrieval by the same user or subsequent users who input the same keywords. The keyword index is modified directly when, for example, a single service or application controls the interaction between user and repository, end to end.

A scan data signal processor is disclosed for use with a laser scanning system having a plurality of different focal zones within which a laser scanning beam is scanned across one or more bar code symbols and an analog scan data signal is automatically produced. The scan data signal processor comprises a first and second derivative signal generation stages, a second-derivative zero-crossing detector, a real-time bar code element detector, and a control logic circuitry. The first derivative signal generation stage derives a first derivative signal from the analog scan data signal. The second derivative signal generation stage derives a second derivative signal from the first derivative signal. The second-derivative zero-crossing detector detects zero crossings in said second derivative signal. The real-time bar code element detector automatically detects the presence and absence of bar code element data encoded within said analog scan data signal. The control logic circuitry automatically activates the second-derivative zero-crossing detector in response to the detection of the presence of bar code element data encoded within said analog scan data signal, and automatically deactivates the second-derivative zero-crossing detector, in response to the detection of the absence of bar code element data encoded within the analog scan data signal. By virtue of the present invention, it is now possible to enable the detection of zero-crossings occurring in the second derivative of the analog scan data signals only when bar code element data has been detected, indicative that a bar code symbol has been scanned. This results in more accurate generation of digital output signals from the scan data signal processor.

Status Date: 2015-06-29

A digital data storage device such as a rotating magnetic disk drive contains an on-board condition monitoring system, comprising a neural network coupled to multiple inputs derived from measured parameters of disk drive operation. The neural network uses a configurable set of weights to compute one or more quantities representing disk drive condition as a function of the various inputs. The weights are stored in a configuration table, which can be overwritten by a host computer. The drive is sold and installed with one set of weights, based on the then existing knowledge of the disk drive designers, and may be updated in the field as the designers acquire experience data by simply writing the weights to the configuration table of the disk drive, without altering disk drive control code or other disk drive features. Preferably, the disk drive designers include as input to the neural network any parameter which might conceivably be useful, even if the designers initially believe that the parameter has no significance. In this case, the designers can assign the parameter a weight of zero during initial release. If subsequent experience then shows that the parameter has some unexpected significance, the neural network can be corrected simply by changing weighting factors, without altering the control programming code.

Defect analysis of an integrated circuit die is enhanced using a method and system that make possible the detection of defect-related heat generation in the die. According to an example embodiment of the present invention, a semiconductor die having a liquid crystal layer is analyzed by detecting a liquid crystal phase change caused by heating the die. The heating causes a first circuit region and a second circuit region to effect a separate phase change in corresponding areas of the liquid crystal layer. A detector is adapted to use time-lapsed analysis to detect the liquid crystal phase change in the area corresponding to the second circuit region before the corresponding areas cease to be separately detectable.

Low dielectric constant films with improved elastic modulus. The method of making such coatings involves providing a porous network coating produced from a resin containing at least 2 Si—H groups where the coating has been thermally cured and has a dielectric constant in the range of from about 1.1 to about 3.5, and plasma treating the coating to convert the coating into porous silica. Plasma treatment of the network coating yields a coating with improved modulus, but with a higher dielectric constant. The coating is plasma treated for between about 15 and 120 seconds at a temperature less than or about 350° C. The plasma treated coating can optionally be annealed. Rapid thermal processing (RTP) of the plasma treated coating reduces the dielectric constant of the coating while maintaining an improved elastic modulus as compared to the initial porous coating. The annealing temperature is preferably in excess of or about 350° C., and the annealing time is preferably at least or about 120 seconds. The annealed, plasma treated coating has a dielectric constant in the range of from about 1.1 to about 2.4 and an improved elastic modulus.

Optical methods for the testing of component areas by using interferometric techniques or processes using structured light, which compute the deformation of the object by means of the picture processing and display the result as a phase difference picture are known. The structure-dependent local deformations are frequently superimposed by whole-body movements or other non-relevant global object deformations, which make it difficult to recognize local structural features, particularly structural defects. With the new picture processing method, the phase difference picture is manipulated in such a way that the local structural features are removed. This manipulated phase difference picture is subtracted from the original phase difference picture, so that a phase difference picture results, which shows only the local deformations. It is then much easier to recognize structural features, particularly structural defects, in the resulting phase difference picture since the interfering, superimposed global deformations are removed.

An apparatus and method for transferring data between a read/write transducer and a data storage medium provides for improved track format efficiency. Data is written to a data sector of the data storage medium using a write current waveform developed in the read/write transducer. The write current waveform is typically at one of several possible states following writing of the data to the data sector. According to the present invention, a transition pattern is generated and used for transitioning the write current waveform from the state following writing of the data to a known state consistent with coding constraints of the data channel. A predetermined data pattern associated with the known state of the write current waveform is written to a pad field of the data sector. The transition pattern and the predetermined data pattern are used to resolve detector and parity post-processor closure decisions during a sector read operation.

The invention uses fuzzy logic and/or probability distributions to automatically calculate and display the effects of contextual information on the confidence that an object in an image is an object of interest. The goal is to assist in determining the location and type of target objects of interest in that imagery. The imagery can come from any kind of imaging sensor or can be non-sensor imagery (e.g., two-and three-dimensional maps), and can be live or archived imagery. The locations of context objects can be provided by a human or a computer. The resulting set of data, including the original imagery, the locations of context objects, any results from AOD, and predictions about target object type and location, can be combined into a display that helps a human better understand where target object appears in the imagery.

The frequency of use of video and other data is increasing. Additionally, video components are typically connected together. The video components may synchronize via a first in first out (“FIFO”) queue. Data may be written into the FIFO queue by a component with a first clock rate, and then the data may be read out of the FIFO queue by a component with a second clock rate. Because of the different clock rates, it is possible that there could be an underflow or overflow of data in the FIFO queue. Typically, when the timing between the components is far apart, the read and write pointers that point into the FIFO queue are realigned by using a reset control signal, which sets both pointers back to address zero of the FIFO queue. The present system provides an improved technique for synchronizing the read and write pointers. In particular, the present system provides a technique for aligning the read and write pointers of a FIFO queue at any time and at any random address. This is especially useful to provide synchronization when a FIFO queue is used to pass data from a video system having a first clock rate to another video system having a different clock rate.

An automated prefix dialing system is disclosed to allow a subscriber/user to automatically insert a predetermined prefix dialing code in certain outgoing telephone call situations. The system is electrically disposed between the telephone company's central office circuit and the subscriber's circuit. The system preferably comprises six sub-circuits: DC power path circuit (off-hook sensor circuit), shadow-ring detector circuit, isolation circuit, DTMF receiver circuit, DTMF generator circuit, and micro controller circuit. When not in use, no power is used by the system. The DC power path circuit, provides power received from the central office line to the various circuits and components of the system when the subscriber's phone is taken off-hook. Off-hook sensor circuitry detects when the telephone has been lifted either in response to an incoming call or to initiate an outgoing call. The shadow ring circuit informs the system if the phone is taken off hook because of an incoming call and functions without any power. When an outgoing call is made, the isolation circuit isolates, the subscriber's phone from the central office line to allow the system to analyze the number being dialed by the user. If the number satisfies certain calling conditions the programmed prefix digits are automatically inserted before the number by the system. Whether or not prefix digits are inserted, DTMF tones, representing the number dialed by the user, must be re-generated by the system and are ultimately transmitted to the central office line, with or without the prefix digits, by the isolation circuit when isolation is removed.

An embedded-controller-based system, such as a personal digital assistant (PDA), includes a system-on-a-chip with a processor, system bus, memory, and system-bus peripherals. The system-bus peripherals include connections to data paths that are not accessible from the system bus during execution of application programs. Associated with these connections are test drivers that include registers that can be written to by the processor via the system bus for software controllability. When the processor executes a test program, it writes test values to these registers. Some bits of the test values are used to control multiplexers so that they can decouple function block ports from the non-system-bus connections and then couple the remaining bits of the registers. In this way, a test program can write data directly to the non-system bus connections. The results of the test data being applied at the source of inter-block connections can be read from the destinations using test samplers. The test samplers can be taps to function block ports that are multiplexed to the system bus for reading during a test procedure for software observability. Thus, both bus connections and non-bus connections can be tested by a program running the system processor without requiring external test equipment.

By providing the transmission models of the present invention, each channel can operate independently, perform unidirectional transmission of address and data signals, and adjust the channel arrangement in accordance with practical requirements. Thereby, the signal transmission between elements can be highly mobile, the idle transmission time between elements can be greatly reduced, and the optimal transmission efficiency can be achieved.

A system for performing a Chien search simultaneously tests multiple elements of GF(2P) as possible roots of a degree-t error locator polynomial &sgr;(x) using a plurality of simplified multipliers that each simultaneously produce the corresponding terms of &sgr;(x). In one embodiment of the system, t−1 simplified multipliers over GF(2P) are used to simultaneously test as possible roots &agr;2, (&agr;2)2, (&agr;2)3 . . . (&agr;2)j. Each multiplier includes a plurality of adders that are set up in accordance with precomputed terms that are based on combinations of the weight-one elements of GF(2P). A summing circuit adds together the associated terms produced by the multipliers and produces j sums, which are then evaluated to test the j individual elements as possible roots. The coefficients of &sgr;(&agr;2)j are then fed back to the multipliers, and the multipliers test, during a next clock cycle, the elements &agr;2*(&agr;2)j, (&agr;2)2*(&agr;2)j . . . , (&agr;2)2j and so forth. Similar multipliers also test the odd powers of &agr; as roots of &sgr;′(x)=&sgr;(&agr;x). If P=mn the system may be implemented using a plurality of GF(2m) multipliers. The field GF(2m) is a subfield of GF(2P), and the elements of GF(2P) can each be represented by a combination of n elements of GF(2m). The error locator polynomial &sgr;(x) can thus be represented by a combination of n expressions &sgr;0(x), &sgr;2(x) . . . &sgr;n−1(x), each with coefficients that are elements of GF(2m). Each of the n expressions has 2m−1 coefficients for the terms x0, x1, x2 . . . x2m−1. Thus, n(2m−2) constant GF(2m) multipliers are used to test each element of GF(2P) as a possible root. The number of GF(2m) multipliers in the system is independent of the degree of the error locator polynomial, and each multiplier operates over a subfield of GF(2P). Accordingly, the system can simultaneously tests j elements using j sets of n(2m−2) constant multipliers over GF(2m).

A graphics system that employs parametric texture maps that are converted from height fields. The system samples a hemisphere equidistantly to produce an array of normals, approximates a dot product of each sampled normal with an arbitrary unit vector, transforms the polynomials back to canonical basis, converts a height field to normals, and for each normal in the height field determines coefficients for a parametric texture map. The system then evaluates a diffuse contribution using the parametric texture map coefficients. The system may also then evaluate a specular contribution using the parametric texture map coefficients. The graphics system renders surface features of a 3D object in a manner that is direction dependent but without the time consuming and expensive calculations involved in the evaluation of lighting equations on a per pixel basis. A parametric texture map holds a set of parameters that define a surface structure in a manner in which the appearance of the surface structure varies in response to a direction vector. The direction vector may be any user-defined vector including a light source vector or a half-angle vector. The parameters are those of a predetermined equation, the evaluation of which does not involve vector calculations. The equation may take any form including a polynomial equation or a non-polynomial equation. The graphic system renders a polygon with the surface structure using the equation.

An embedded data acquisition and control system for a precision instruments, such as a non-invasive glucose prediction instrument is disclosed. One feature of the invention provides synchronization of stepper motor position and analog-to-digital converters. An embedded controller is provided that controls the stepper motor driver directly to minimize the wavelength shift error due to the asynchronous condition. The controller synchronizes the event of reading the A/D converters with each stepper motor position. Because the stepper motor controls the wavelength of the monochromator optical output, the net result is that each A/D conversion recorded by the embedded controller is precisely tracked to a specific wavelength. Another feature of the invention provides closed loop motor position control for enhanced system performance. In the closed loop system, a position encoder is coupled to the stepper motor shaft. The encoded position signal is processed by a digital encoder at the bipolar stepper motor drive, resulting in an actual position feedback to the embedded controller. Because the embedded controller has the position feedback, it can initiate the next step command as soon as the position feedback reaches its target. The step rate is increased by reducing the time delay that was set by a conservative value as indicated in the open loop control mode. One advantage of this method is to achieve highest speed in all load conditions without missing steps. A further feature of the invention provides optical Isolation to minimize motor noise. Thus, optical isolation is provided at a bipolar stepper motor drive and embedded controller interface. To maximize system sensitivity, optical isolation is implemented between the embedded controller and the stepper motor drive.

A magnetoresistive-effect device includes a multilayer film, hard bias layers arranged on both sides of the multilayer film, and electrode layers respectively deposited on the hard bias layers. The electrode layers are formed, extending over the multilayer film. Under the influence of the hard bias layers arranged on both sides of the multilayer, the multilayer film, forming the magnetoresistive-effect device, has, on the end portions thereof, insensitive regions which exhibit no substantial magnetoresistive effect. The insensitive region merely increases a direct current resistance. By extending the electrode layers over the insensitive regions of the multilayer film, a sense current is effectively flown from the electrode layer into the multilayer film. With a junction area between the electrode layer and the multilayer film increased, the direct current resistance is reduced, while the reproduction characteristics of the device are thus improved.

A method and apparatus that utilizes a simplified, localized version (“a local data-dependency stall”) of a global data-dependency stall to avoid re-reading of a register file to improve the performance of a pipelined microprocessor. A non-asserted local data-dependency stall indicates that source operand for an instruction is correct. Accordingly, when a global data-dependency stall arrives, the instruction is stalled in a stage without re-reading the register file. Without the simplified, localized version of the global data-dependency stall, the source operand data is not known to be correct and is indeed assumed to be incorrect. Therefore, when the global data-dependency stall arrives, a complete re-computation of the source operand data must be performed, including a re-read of the register file. Likewise, an asserted local data-dependency stall indicates that source operand for an instruction is not correct. Accordingly, the instruction is stalled when the local data-dependency stall is asserted and until the data for the instruction is available. The available data is forwarded directly to the stalled instruction.

The present invention involves methods and devices which enable discrete objects having a conducting inner core, surrounded by a dielectric membrane to be selectively inactivated by electric fields via irreversible breakdown of their dielectric membrane. One important application of the invention is in the selection, purification, and/or purging of desired or undesired biological cells from cell suspensions. According to the invention, electric fields can be utilized to selectively inactivate and render non-viable particular subpopulations of cells in a suspension, while not adversely affecting other desired subpopulations. According to the inventive methods, the cells can be selected on the basis of intrinsic or induced differences in a characteristic electroporation threshold, which can depend, for example, on a difference in cell size and/or critical dielectric membrane breakdown voltage. The invention enables effective cell separation without the need to employ undesirable exogenous agents, such as toxins or antibodies. The inventive method also enables relatively rapid cell separation involving a relatively low degree of trauma or modification to the selected, desired cells. The inventive method has a variety of potential applications in clinical medicine, research, etc., with two of the more important foreseeable applications being stem cell enrichment/isolation, and cancer cell purging.

This invention can suppress overshoot/undershoot, and can maintain the improvement effect of the leading edge of an edge portion. For this purpose, a second derivative signal generator (1) generates a second derivative signal (s5) on the basis of time-serially input three successive pixels. A second derivative signal suppression unit (2) generates a signal (s8) obtained by suppressing the second derivative signal, and a signal (s9) indicating the sign of the second derivative signal. The absolute values of the differences between the pixel of interest, and its neighboring pixels are computed, and a smaller one of the absolute values is selected as a signal (s14) by a minimum value selection circuit (18). By multiplying the obtained signals (s8, s9, s14) by a multiplier (19), an edge-emphasizing signal (s15) is generated. The edge-emphasizing signal (s15) is added to the signal of the pixel of interest by an adder (20), thus obtaining an edge-emphasized signal s16.

Methods for remotely sensing sound waves in an optically transparent or semitransparent medium through detecting changes in the optical properties of the medium, which are caused by the sound waves. For example, to implement a microphone that can sense sound at a distance from the sound source. The variations in the attenuation or the phase of a beam of light that is received after passing through the sound waves are sensed and converted to an electrical or other signal. For the attenuation method, the wavelength of the beam of light sensed is selected to be one that is highly attenuated by a constituent of the medium, so that the changing instantaneous pressure of the medium due to the sound pressure waves can be detected through the changing light attenuation due to the changing density of the air along the light path. For the phase shift method, the velocity of light, and therefore its phase is changed by the changing density of the air due to the sound waves, and this can be detected through interferometric means.

A new scheduling discipline is disclosed for the forward link of a wireless network such as a CDMA network. The new discipline, which we denominate Modified LWDF (M-LWDF), resembles the known LWDF discipline in that only one queue is served at a time, and the queue to be served is that having the largest weighted delay. According to M-LWDF, the weighted delay of the i'th queue is defined as wherein Wi(t) is a packet delay, a queue length, or an increasing function of packet delay or queue length for the i'th queue, ci(t) is a weight coefficient descriptive of channel conditions for the i'th user, and &ggr;i is a fixed constant that can be chosen arbitrarily. We have found that if any scheduling discipline can yield stable queues for a given traffic pattern of arriving packets, then M-LWDF can, even under changing channel conditions. Moreover, we have found that M-LWDF can provide favorable QoS in terms of delay bounds.

A cellular interface unit is disclosed and is used in association with a trunk line of a private branch exchange or a key system unit. The cellular interface unit includes a cellular-type transceiver, a power supply and control circuitry. The cellular-type transceiver is used for mobile-to-mobile telephone calls with remote cellular telephone units and for mobile-to-landline telephone calls with remote landline telephone units. The control circuitry is used to convert signals between the cellular transceiver and the private branch exchange or key system unit so that the transceiver and its interconnected PBX or KSU function appropriately and so that use of the trunk line establishes a cellular telephone call, while resembling a landline telephone call through the PBX or KSU. Included within the control circuitry is call disconnection supervision circuitry that is responsive to the receipt of an end of call signal from the mobile telephone switching office. In response to the receipt of such signal, the call disconnection supervision circuitry causes the private branch exchange or key system unit to deactivate its associated trunk line and tear down the telephone call by monitoring a physical quantity attributable to the transceiver associated with the interface unit and responding to a change in that physical quantity. The power supply provides a source of electrical energy for the cellular transceiver and the control circuitry.

A system and method are provided for counting a number of clock cycles. In one embodiment, the system comprises a cascaded series of write latches and a cascaded series of erase latches. The output of each of the write latches is electrically coupled to a respective diverting multiplexer configured to divert a counting signal from the cascaded series of write latches to the cascaded series of erase latches. In order to count a specific number of cycles of the clock, one of the diverting multiplexers is set so as to divert a logical “1” advancing along the write latches into the erase latches. A specific number of clock cycles is counted by forcing a logical “1” to advance through a predetermined number of write and erase latches. Generally, the number of write and erase latches used to count a given number of clock cycles is even. Consequently, the present invention also includes an odd latch to enable the counting of an odd number of clock cycles. Also, a number of reset signal pathways are employed to reset the write latches as the logical “1” is advanced along the erase latches.

Status Date: 2011-08-15

The invention provides a microinsertion-based, trans-complementation method of in vitro oocyte activation useful to identify properties of sperm-borne oocyte-activating factor(s) (SOAF) and ooplasmic interactions with sperm components at fertilization. The invention provides at least one detergent-insoluble heat-sensitive component of the perinuclear matrix of a spermatozoon (SOAFm) that acts coordinately with at least one heat-stable submembrane sperm component. SOAFm is solubilized in vitro (SOAFs) under reducing conditions similar to those encountered in the ooplasm. By the method of the invention, the failure of heat-inactivated demembranated sperm heads to activate an egg is rescued by coinsertion of SOAFs into an oocyte. SOAFs is protease-sensitive and is liberated from demembranated heads in a temperature-dependent manner that inversely correlates with the ability of demembranated sperm heads to activate oocytes.

A spin valve sensor of a read head has a platinum manganese (PtMn) pinning layer that pins a magnetic moment of an antiparallel (AP) pinned layer structure. The pinned layer structure has a first AP pinned layer exchange coupled to the pinning layer so that the magnetic moment of the first AP pinned layer is pinned in a first direction and has a second AP pinned layer that has a magnetic moment pinned in a second direction antiparallel to the first direction. A free layer structure of the spin valve sensor is located asymmetrically between first and second shield layers so that when a sense current is conducted through the sensor a net image current field is executed on the free layer structure by the shield layers. For example, if the second AP pinned layer is thicker than the first AP pinned layer HI=HFC+HD+HIM is exerted on the free layer structure where HI is a sense current field from all conductive layers other than the free layer structure, HFC is a negative ferromagnetic coupling field from the second AP pinned layer, HD is a net demagnetization field from the AP pinned layer structure and HIM is a net image current field from the shield layers.

An adaptive multi-modal motion estimation algorithm for video compression builds a luminance pyramid for each image of a moving image sequence. From the top level image of the luminance pyramid a global motion vector is determined between images at times t and t+n. The global motion vector is used as a pivot point and to define a search area. For each block of a current top level image a search for a match is carried out around the pivot point within the search area. The resulting block motion vectors serve as initial conditions for the next higher resolution level. A refinement process results in a displaced frame difference value (DFD) for each block as an error measure. If the error measure is small, the motion vector is chosen as the motion vector for the current block. If the error measure is large, then a search within the search area around a zero motion pivot point is conducted. The motion vector that results in the smallest error measure is chosen as the motion vector for the current block. The refinement and zero pivot searches are repeated for each level down to the full resolution base of the pyramid, resulting in the desired estimated motion vectors for the image.

The first (reference) wavelength is preferably chosen to be at an isosbestic point for the two components, commonly the oxygenated and deoxygenated forms of hemoglobin. The absorption at the isosbestic point is subtracted from the absorption at the other wavelengths. Using these differences in absorption, the amount of each of the components encountered by the light may be determined without determination of pathlength, which would be required to determine the concentration. In order to determine the oxygenation state, i.e. ratio of oxygenated to deoxygentaed blood components, knowledge of the relative amounts suffices. Interference from other light-absorbing components, specifically those that respond to the oxygenation state of the body part (such as cytochrome c oxidase) is in the three wavelength method eliminated by reiterative correction.

Status Date: 2015-08-17

A system and method for performing peak-to-average power ratio reduction in a transmitter using pulse amplitude modulation (PAM) encoding. Broadly, a transmitter is configured to perform active digital filtering to detect encoded data symbols that if uncorrected would lead to relatively high analog signal peaks in the data transmission. A prediction is made of the peak values that would be applied at the digital to analog converter (DAC) if the original output of the Tomlinson precoder was sent into the shaping filter. If the absolute value of the predicted peak value exceeds a threshold, a correction of a full 2L step is applied for one sample of the Tomlinson precoded stream. The correction step is applied in such a way as to reduce the resulting peak output. Two methods of predicting the peak values are presented. The first method segments the shaping filter into causal and non causal portions so that no extra delay is introduced. The second method uses a two-stage approach where a first pass provides symbols without correction, then corrected symbols are injected in a duplicate modulation filter (this implies an extra delay equal to the filter delay). A variation of the two-stage approach takes advantage of the linear aspects of the Tomlinson preceding.

A constant output signal can be achieved by controlling a gain variable amplifier 2 based on a level of an output signal which is derived by variably amplifying a receiving signal S1 (input signal). An AGC output signal S11 is detected by a detector circuit 3, then a detected voltage signal S7 is converted into a digital signal by an A/D converter 4 to output it to a CPU 5. Then, the CPU 5 generates a control signal S8 based on the detected voltage signal S7, then an A/D converter 6 converts the control signal S8 into the analogue signal, and then the signal is sent out to the gain variable amplifier 2 to execute gain control. At this time, an RSSI detector portion 9 detects an RSSI signal S10 corresponding to a transmitting signal level from the receiving signal S1, and then the CPU 5 sends out the control signal S8 stored at the time of preceding execution of the gain control when the RSSI signal S10 is reduced below a predetermined threshold value S12. In the weak received electric field strength, the control voltage for the gain variable amplifier is prevented reduction, and the proper automatic gain control can be made possible to thus achieve the good receiving characteristics.

A disk drive with a detector circuit is connected to the distal end of a two-stage actuator. The actuator has a micro actuator for fine track positioning of a read/write head relative to a disk. Intermittent contact between the head and the disk produces forces that are detected and measured by the micro actuator drive circuitry. These measurements are used to determine if excessive contact is occurring between the head and the disk. Alternatively, the present invention also uses a differential method where the output signals from multiple micro actuators are compared to improve noise immunity. In addition, comparisons between the forces at the proximal and distal ends of the micro actuators are used to better identify the source of such forces. For example, this allows the system to distinguish between common mode forces such as those generated by windage and flex cable bias, from forces generated by intermittent head-disk contacts.

Status Date: 2015-08-24

Faults on power lines are detected by measuring the voltage and current at one end of a power line and using these measurements, together with values of series and shunt parameters of the line, to calculate values of voltage and current at an intermediate point on the line—the so-called “reach point”. At least the calculated voltage is used to determine whether a fault lies within a particular zone on the line. The calculation utilizes a value of a derivative of the measured current with respect to time and is able to take into account the sectioning of a line into discrete lengths corresponding to, for example, overhead and cable sections. To increase accuracy, the line or each discrete section of the line is conceptually divided into subsections each having its own parameter values. In a second aspect, detection of whether a fault lies within a particular zone involves the measurement of the voltage and current at one end of the line both before and after the fault, the calculation of a complex impedance between an intermediate point of the line and a reference point, normally earth, the use of these measured values and values relating to line parameters and to a source impedance at the second end of the line, and the determination of the sign of the complex impedance.
