Abstract: A passive start and entry (PASE) system monitors a signal strength of a LF signal detected by a fob. The fob reports the signal strength back to an electronic control unit using an RF signal. The electronic control unit compares the signal strength to a predetermined threshold. If the signal strength is below the threshold, the electronic control unit determines that the fob may not be receiving the LF transmission due to interference and takes corrective action.

Abstract: A method of assembling and sealing a circuit board within a housing includes the steps of placing the circuit board within the housing, filling the space above the circuit board or around the circuit board with a potting material, and then exhausting that cavity of gases during a curing process of the potting material. Exhausting of the gases is performed and accommodated by a vent opening. An access opening is in communication with the vent opening and provides for the injection of sealant to block the vent opening.

Abstract: An electronic high frequency induction heater driver, for a variable spray fuel injection system, uses a zero-voltage switching oscillator that is impedance coupled to an imbedded multiple function signal separator and integrated with a conventionally implemented electronic fuel injector driver. The induction heater driver, upon receipt of a turn-on signal, multiplies a supply voltage through a self-oscillating series resonance, and couples the high frequency energy to a high pass filter such that the useful energy is utilized in an appropriate loss component so that fuel inside a fuel component is heated to a desired temperature.

Abstract: A magnetometer assembly (22) for a torque transducer (10) includes inner and outer coils (34,38,36,40) wrapped and supported on a bobbin assembly (22). The bobbin assembly (22) includes upper and lower axial portions (21,23) divided by a middle flange (28). The middle flange (28) includes a plurality of notches (32) that are disposed equal angularly about an axis (18). A plurality of corresponding magnetic strips (42) extend axially through each of the notches (32) and through the entire length of the magnetometer assembly (22). The magnetic strips (42) are disposed between an inner and outer coil assembly (34,38,36,40) and becomes saturated in the presence of a magnetic field. Divergent magnetic fields created by torque applied to a torque transducer element (12) disposed within the magnetometer assembly (22) and detected and measured to provide an indication of applied torque.

Abstract: A system for monitoring conditions within a tire (12) including a sensor assembly (14) including a pressure sensor (36), an accelerometer (34), a temperature sensor (32), and a transmitter (40) to transmit signals indicative of current tire conditions. A remote transmitter (22) for actuating a remote keyless entry system (19) emits a signal to actuate a function of the keyless entry system (19) such as unlocking doors (20) of the motor vehicle (10). A receiver assembly (16) includes an amplitude shift keyed receiver (52) and a frequency shift keyed receiver (58) selectively engagable to receive radio frequency transmissions from the tire monitoring system or the remote keyless entry system (19).

Abstract: In a method for reducing “blow-out” of annular welds for attaching components in a fuel injector, a relief region is formed on radially-facing surfaces of the components. The relief region is adjacent to a press-fit region. The components are then pressed together, and a weld is made in the relief region. A sealed gap is thereby formed in the relief region between the weld and the press-fit region. The sealed gap provides for the expansion of trapped gases that could otherwise “blow out” the liquid weld bead.

Abstract: An alternating current (AC) bus malfunction detection and protection module monitors an AC voltage that is provided on a bus by a house keeping power supply of a power system. If the AC voltage on the bus falls below a first level, the module provides a delay before power inverter switching is disabled. If the AC voltage on the bus falls below a second level, the module disables the power inverter switching without delay.

Abstract: An illuminated gauge includes a dial with at least first and second ranges of markings. The first range of markings indicates one type of vehicle information and the second range of markings indicates another type of vehicle information. A single motor is used to move a common pointer between the first and second ranges of markings. A selector is to be operated by a user to select between the different types of vehicle information.

Abstract: A light distributing assembly for a vehicle instrument panel includes a light source that emits light in a first direction. A first surface that is transverse to the first direction receives the light and changes the direction of the light to a second direction. A vehicle instrument panel housing having a second surface receives the light from the first surface and reflects a portion of the reflected light toward a vehicle display surface to illuminate the vehicle display surface.

Abstract: A light housing for an instrument panel includes an interior surface for reflecting and blending light from a plurality of light sources substantially uniformly from an opening. The light housing is mounted to a circuit board and surrounds a plurality of light sources. An interior surface of the light housing includes inwardly protruding ribs that reflect and direct light to blend the separate light sources and provide a substantially uniform light intensity for illuminating a rotating pointer.

Abstract: A fuel pump module is provided for delivering fuel to an engine. The module includes a fuel pump 16 for pumping fuel to the engine. A filter 12 filters fuel prior to being pumped to the engine. A pump retaining structure 10 is coupled to the filter 12. The pump retaining structure 20 includes spring structure 22 constructed and arranged to resiliently support the fuel pump in a suspended manner with respect to the filter.

Abstract: An instrument display for a vehicle comprises a first light guide (14) in communication with a first light source (18). (FIG. 1A). The first light guide (14) directs light to a first instrument mark (22). A second light guide receives light from a second light source (34). The second light guide (26) is spaced from the first light guide (14) and directs light to a second instrument mark (24). A support (42) connects the first light guide (14) and the second light guide (26) and limits light transmission between the first light guide (14) and the second light guide (26).

Abstract: By-pass structure (45) is connected between a high pressure portion of a fuel pump (16) and an inlet of a jet nozzle (24) of a jet assembly (18) of a fuel delivery module (10) of a vehicle. The by-pass structure is constructed and arranged such that under certain conditions when the flow of fuel from the low pressure portion of the fuel pump alone is insufficient to operate the jet pump assembly, fuel is selectively permitted to flow through the by-pass structure from the high pressure portion of the fuel pump to the inlet of the jet nozzle ensuring that a sufficient flow of fuel is present at the jet assembly to draw fuel into the reservoir.

Abstract: In order to simplify air flow control in a self-contained air supply system, an average control speed is calculated on the basis of a defined movement of the air springs (3, 4) and compared with an optimum control speed. The result of the comparison of the control speeds is used to determine the need for or the excess of an amount of compressed air. There are at least three possibilities for calculating the average control speed.
