  • Child restraint system comprising weight sensor
    Patent number: 7385520
    Abstract: A child restraint system for transporting a child within an automotive vehicle includes a weight sensor for determining the weight of the child and compares the child's weight to a recommended weight range. The weight sensor is disposed within a cushion that lines a shell and provides an electrical signal to a control unit. The control unit processes the electrical signal and provides an alert signal when the weight is not within the recommended range. Also, the child restraint system may include a second sensor for sensing a condition that depends upon the child's weight such as directional orientation or angular orientation of the child restraint system, or location or tension of a vehicle seat belt or tether that secures the child restraint system within the vehicle, or the location or tension of a harness for restraining the child occupant within the child restraint system.

  • Wristband reader apparatus for human-implanted radio frequency identification device
    Patent number: 7385498
    Abstract: A reader apparatus for an RFID-implanted human user is incorporated into a wristband such as a bracelet or a watchstrap worn by the user. The RFID device is subcutaneously implanted in the vicinity of the user's wrist, ensuring close proximity of the reader apparatus to the RFID device to support reliable near-field RF communications at low power levels. The wristband includes a reader coil having a plurality of turns, a reader circuit, and a rechargeable battery for powering the reader circuit. The same reader coil is used to simplify recharging of the battery by inductively coupling the reader coil to a charging coil disposed in a small charging stand or storage case. In watch strap applications, the reader circuitry and battery are disposed in a watch case affixed to the strap, and the watch case includes an alphanumeric display for communicating information from the RFID device to the user.

  • Method of estimating the temperature of an oxygen sensor heating element
    Patent number: 7385161
    Abstract: The resistance of an oxygen sensor heating element is estimated by modeling the effects of physical and electrical heating on the resistance of the heating element lead-in conductors, and subtracting the lead-in conductor resistance from a measure of the heating circuit resistance. The lead-in conductor resistance model is based on the temperature of the oxygen sensor boss and the current carried by the lead-in conductors. The heating element temperature is calculated from the determined heating element resistance and initial (cold-start) parameters of the heating circuit.

  • Capacitive pressure sensor
    Patent number: 7383737
    Abstract: A capacitive pressure sensor includes a electrically conductive, generally piston shaped diaphragm with a flexible base wall configured to deflect under pressure. The diaphragm is generally U-shaped in cross section. The base wall includes an upper, flat sensing surface which acts as a capacitive electrode. The diaphragm further includes a step around a radially-outermost perimeter which is elevated from the flat sensing surface. A sensing electrode body is located on top of the step and creates a capacitive sensing cavity between the sensing surface and the bottom surface of the electrode body. On the bottom surface of the electrode body is formed a center, circular electrode and a ring electrode that surrounds the center electrode. The center electrode and the sensing surface form a variable capacitor which changes with pressure and the ring electrode and the sensing surface form a reference capacitor.

  • Outward-opening gas-exchange valve system for an internal combustion engine
    Patent number: 7377249
    Abstract: An outwardly-opening gas-exchange valve assembly for an internal combustion engine. The valve assembly includes a port in a firing chamber in an engine head, the port having a valve seat on a side opposite from the firing chamber. A piston-shaped poppet valve head slides in a bore in the engine head for mating with the valve seat to occlude passage of gas across the valve seat. Withdrawal of the poppet valve head from the seat opens the firing chamber to communication with an intake or exhaust manifold runner in the engine head. The poppet valve head may be actuated by an overcenter lever arrangement actuated selectively by hydraulic pressure or mechanical actuation. In a preferred embodiment, OO intake and exhaust valves are radially arranged in a hemispherical fire deck and may include an adjustable pitch helical channel to induce swirl to the incoming gas.
