The present invention is directed toward a device for biometric authentication. The device comprises an infra red signal transmitter, signal receiver, memory module, and processing module. The signal transmitter transmits infrared energy toward a user. The infrared energy is partly absorbed and partly reflected by the user's body. The infra red signal receiver collects partly reflected infrared energy. The memory module stores the data, and the processing module processes and compares the reflected infrared energy and stored data for use in biometric authentication.

Processes for forming high density gap-filling silicon oxide on a patterned substrate are described. The processes increase the density of gap-filling silicon oxide particularly in narrow trenches. The density may also be increased in wide trenches and recessed open areas. The densities of the gap-filling silicon oxide in the narrow and wide trenches/open areas become more similar following the treatment which allows the etch rates to match more closely. This effect may also be described as a reduction in the pattern loading effect. The process involves forming then planarizing silicon oxide. Planarization exposes a new dielectric interface disposed closer to the narrow trenches. The newly exposed interface facilitates a densification treatment by annealing and/or exposing the planarized surface to a plasma.

The at least one plate is adapted to be customized to the shape of a patient's bone. The system also includes a plurality of fasteners including at least one locking fastener for attaching the bone plate to the bone. At least one of the holes is a threaded hole.

A stent and method of its use, the stent in its expanded configuration, exhibiting varying outward radial force along its length. In use, the expanded stent is of a tapered configuration which provides greater force in vessel regions requiring greater force and less force in regions requiring less. In particular the stent is useful in the ostium regions and at areas of bifurcation in vessels. Varying force over the length of the stent is achieved by varying the number of elements, the density of elements, the thickness of the elements making up the stent body, and maintaining a substantially metal to artery ratio in the expanded stent over its length.

Method for well re-stimulation treatment using instantaneous shut-in pressure (ISIP) to guide the design and execution of refracturing stages. Pore pressure and optional cluster stresses are determined at a start of the treatment. Goal ISIPs for the refracturing correspond to undepleted regions of the formation, and target ISIPs versus treatment progression/stage range from about a lowest pore pressure corresponding to depleted regions of the formation up to within the goal range ISIPs. Diversion and proppant pumping schedules are designed, and the refracturing treatment is initiated in accordance with the design. ISIP is measured at stage end, and if it varies from the target ISIP, subsequent stages are modified from the design as needed to more closely match the ISIP schedule.

A stent is provided with a series of short pieces or sections connected together by at least one polymer fiber or wire. The polymer fiber or wire can be biodegradable or durable.

Method and systems are disclosed for enabling a computer system to generate a request that includes an instruction identifying the authentication method or methods to be used when authenticating a subset of the client computer systems or users network connected to a server computer system. The subset of client computer systems or users may include as little a single computer system or user. The request is then transmitted to the server computer system. When receiving subsequent requests for service from any of the subset of client computer systems or users, the server computer system will refer to the information in the instruction to determine which authentication methods are acceptable in authenticating the client computer system or user.

A transmission line equalizer, communication system, and method are provided for adaptively compensating for changes in transmission path length and transmission path medium. Within the equalizer is a filter that exhibits a high pass characteristic and, more specifically, has an inverse frequency response to that of the transmission path. The inverse filter can include a pair of amplifier stages coupled in parallel, with a mixer chosen to adaptively select portions of one stage over than of the other. The dual stage inverse filter can, therefore, adapt to greater transmission path lengths and/or attenuation. A feedback architecture is used to set the inverse filter response by measuring the amplitude of a communication signal output from the inverse filter during periods of low frequency. A peak detector will capture a peak-to-peak voltage value during those periods, and adjust the output of the slicer to match a launch amplitude of the communication signal. The peak detector within the feedback architecture helps ensure the predicted amplitude matches the launch amplitude to minimize over-compensation or under-compensation even though a different integrator might register no difference in integrated voltage or energy at the output of the inverse filter compared to the output of the slicer.

A proportional force input apparatus for an electronic device includes a mechanism operable by a user of the electronic device, such as a stylus inserted into a spring-loaded socket of the device. The mechanism provides a tactile feedback to the user proportional to a force applied by the user. A variable strength sensor detects the force applied by the user to the mechanism and converts this to an electrical signal proportional to the force applied by the user. A processor operates to input the electric signal from the variable strength sensor and provide force information to an application running on the electronic device. Optionally, a second sensor can detect rotation of the stylus. As a result, a stylus can be used to provide vector information to an application such as a game.

The light emitting device is connected to the substrate directly or indirectly through a wiring substrate. The core of the substrate may be, for example, ceramic, Al₂O₃, AlN, alumina, silicon nitride, or a printed circuit board. The copper layer may be bonded to the core by a process such as direct bonding of copper or active metal brazing.

A micro-machined MEMS resonator gyroscope and accelerometer is fabricated from an epilayer semiconductor wafer to incorporate a substantially planar, H-shaped resonator mass suspended from a support plate by two opposed elongated springs that couple to the relatively short crossbar member of the H. The masses are harmonically oscillated relative to the support plate and a baseplate portion, and two orthogonal modes of the structure corresponding to the two nearly degenerate fundamental torsional modes thereof are used for sensing angular rate about one axis, and linear acceleration along two axes, of the sensor. The H-shaped mass advantageously incorporates a relatively high length-to-width aspect ratio, and in one embodiment, the springs may advantageously incorporate either a square cross-section, such that the structure can be tuned to substantially match the fundamental frequencies of the two resonance modes of the structure by removing, e.g., by an etching process, a small amount of material from the upper surfaces of the springs.

Reliability of circuit packaging while accommodating larger chips and increased temperature excursions is achieved by use of compliant pads only at the locations of connections between packaging levels, preferably between a laminated chip carrier and a printed circuit board. The invention allows the coefficient of thermal expansion of the chip carrier to be economically well-matched to the CTE of the chip and accommodation of significant differences in CTEs of package materials to be accommodated at a single packaging level. The compliant pads are preferably of low aspect ratio which are not significantly deflected by accelerations and can be formed on a surface or recessed into it. Connections can be made through surface connections and/or plated through holes. Connection enhancements such as solder wettable surfaces or dendritic textures are provided in a conductive metal or alloy layer over a compliant rubber or elastomer layer which may be conductive or non-conductive.
