  • Patent number: 7294552
    Abstract: A method for making a subsurface electrical contact on a micro-electrical-mechanical-systems (MEMS) device. The contact is formed by depositing a layer of polycrystalline silicon onto a surface within a cavity buried under a device silicon layer. The polycrystalline silicon layer is deposited in the cavity through holes etched through the device silicon and reseals the cavity during the polycrystalline silicon deposition step. The polycrystalline silicon layer can then be masked and etched, or etched back to expose the device layer of the micromachined device. Through the layer of polycrystalline silicon, a center hub of the device may be electrically contacted.

  • Patent number: 7293626
    Abstract: A steering system for a vehicle may include a load displacement system allowing transient loads of the steering mechanism to be displaced. The steering system may also include a first coupling mechanism coupling an electric motor to a rack housing, and a second coupling mechanism coupling a ball nut to a rack. A method for providing an actuation force to a rack of a vehicle includes isolating non-axial loads from an electric motor of a steering system and isolating non-axial loads from a linearly actuatable member of a rotary-to-linear conversion device in the steering system. An actuator for a steering system may include a rotary to linear actuator, a movable linear section, and an interface between the rotary to linear actuator and the linear section.

  • Patent number: 7296123
    Abstract: A system for acquiring information on the operation of an electronic control unit (ECU) includes a controller and a non-volatile memory. The controller is coupled to address and data buses of a central processing unit (CPU), which is located within an electronic control unit (ECU). The controller includes a register and/or a logging buffer for facilitating ECU analysis. The non-volatile memory is located within the ECU and is coupled to the address and data buses of the CPU. The register logs the current memory address of the non-volatile memory, when the controller determines the current memory address is a memory address of interest. The logging buffer logs the current memory address of the non-volatile memory each time the controller determines the current memory address is a memory address of interest.

  • Patent number: 7295771
    Abstract: Video components attributable to ambient lighting in a stream of digital images of a scene illuminated by both ambient and active sources are eliminated in each image frame, leaving only video components attributable to the active source. The spectrum of the active source is encompassed by the ambient source, and spectral filtering defines a primary channel comprising video components in a primary spectrum encompassing both active and ambient lighting and a secondary channel comprising video components in a secondary spectrum encompassing only ambient lighting. The pixels of the secondary channel are scaled by a factor correlating the spectral reflectances of the primary and secondary spectra, and the scaled secondary channel is subtracted from the primary channel to produce an ambient corrected image. The pixels of the ambient corrected image are further scaled to compensate for spectral filter bleeding of the active source into the secondary channel.

  • Patent number: 7293460
    Abstract: A three-axis accelerometer is provided for sensing acceleration in three orthogonal axes. The accelerometer includes a support substrate, fixed electrodes having fixed capacitive plates fixed to the support substrate, and a movable inertial mass having movable capacitive plates capacitively coupled to the fixed capacitive plates. The accelerometer includes banks of fixed and movable capacitive plates oriented to sense acceleration in orthogonal X- and Y-axes. Additionally, the accelerometer includes fixed and movable capacitive plates having a height variation between adjacent plates to sense acceleration in the vertical Z-axis. Input signals are applied to certain electrodes coupled to the fixed capacitive plates, and an output signal is generated on the inertial mass, which is indicative of acceleration in each of the sensing axes. The output signal may be further processed to generate individual acceleration outputs for each of the sensing axes.

  • Patent number: 7294424
    Abstract: A solid-oxide fuel cell stack having a plurality of fuel cells connected in series and disposed as two stacks side-by-side in head-to-tail configuration, connected in series across one end and having cathode and anode current collectors mounted side-by-side on a stack base at the other end. Each current collector is a flat plate extending from the stack footprint. Surrounding the stacks is a cover-sealing flange so formed that when the cover is in place a thermal jacket is formed around the stacks. The current collectors are electrically insulated from the sealing flange and cover by a gasket, and extend outwards from the flange for electrical attachment to a load. This arrangement permits the stacks to be fully assembled and the stack cover secured and sealed in place without need for passing electrical leads through openings in the cover which must be subsequently sealed.

    Abstract: A phaser for controlling the timing between a camshaft and a timing gear having a rotor with at least one vane and a stator with at least one recess the phaser allowing limited rotational movement of the rotor with respect to the stator. The vane divides the recess into first and second pockets, wherein the introduction of a fluid into the first pocket causes the rotor to move in a first rotational direction relative to the stator, and in that the introduction of a fluid in the second pocket causes the rotor to move in the opposite rotational direction. A control ring is provided for selectively opening and closing a fluid connection between the pockets to allow fluid to flow between the pockets using the pressure difference of the fluid in each of the pockets to transport the fluid from the one to the other pocket.

  • Patent number: RE39891
    Abstract: A novel impeller for a regenerative turbine fuel pump improves the efficiency of the pump and yet still retains a geometry that allows it to be manufactured by conventional injection molding techniques at a relatively low cost. The impeller comprises a hub, an outer ring and a plurality of innovative V-shaped vanes. The hub defines an aperture into which the shaft of the pump is securable to allow the hub to rotate about a center axis. The outer ring is concentric to the hub. The vanes extend from an outer surface of the hub to an inner surface of the outer ring. Each vane comprises an entrance portion that extends from the outer surface of the hub and an exit portion that extends from the entrance portion to the inner surface of the outer ring. Each vane has a V-shape of a prespecified angle centered relative to a plane normal to the center axis.
