Abstract: A multi-pin electrical connector including a first connector portion and a second connector portion. Seal retaining rings snapped into the connector portions seal and retain cavity terminal blocks located within each respective connector portion. A locking collar employs a ramped locking feature to snap and secure the first and second connector portions in an interlocked, assembled state.

Abstract: A gas sensor is created comprising an electrochemical cell having a solid electrolyte layer disposed between an exhaust gas electrode and a reference electrode. A resistor is disposed in electrical communication with a heater and the reference electrode. The resistor can be disposed on a side of the gas sensor; on a side of the gas sensor such that the resistor is electrically connected through a via hole; over at least a portion of at least two sides of the gas sensor; or disposed in a void extending at least from the heater to the pump electrode, such that the void extends to at least a surface of the gas sensor, extends to at least partially through the gas sensor, or extends completely through the gas sensor. A method for using this gas sensor comprises applying a voltage to the heater within the gas sensor. A current is directed through the resistor to the reference electrode to pump oxygen into the reference electrode.

Abstract: A locking pin mechanism disposed in a bore in a cam phaser rotor vane for controllably engaging the camshaft sprocket to rotationally lock together the rotor and stator of a vane-type camshaft phaser. A lock pin sleeve in the bore extends from the vane through a slot in the cover plate. Disposed within the sleeve is a slidable lock pin having a locking head for engaging the sprocket and a tail portion extending through the outer end of the sleeve. The tail portion of the lock pin may be manually retracted by an operator while the phaser is being installed or removed from the engine, thus preventing damage from high torque exerted via the phaser attachment bolt in bolting the phaser to the engine.

Abstract: A roll arming sensor is provided for determining an arming signal for use on a vehicle for rollover detection. The roll arming sensor includes a light source for generating a light beam and a receiver for detecting the light beam. Disposed substantially horizontal between the light source and receiver are first and second cylindrical members, both oriented substantially parallel to the longitudinal axis of the vehicle. The first and second cylindrical members each have a window extending therethrough for passing the light beam during normal vehicle travel. Each of the first and second cylindrical members are movable to a second position upon experiencing an armed condition, such as a roll event, to prevent the optical beam from passing to the receiver, thereby generating an arming signal for use with a rollover sensor.

Abstract: An impulse noise suppression circuit for an integrator-based ion current signal processing system includes a one-shot circuit activated by a trigger signal that is produced when a noise transient in a bandpass filtered ion current signal exceeds a predetermined threshold. The output pulse of the one-shot circuit is selected to have a pulse width configured to mask a substantial portion of the noise transient without masking the remaining filtered ion current signal during the remainder of a knock window in which knock is detected.

Abstract: A disc brake assembly includes a rotatable hub and at least one disc supported on the hub for rotation therewith about an axis, and slideable axially along the hub. A guide member is disposed between the hub and disc. A spring member is separately formed from the guide member and acts between the guide member and the hub to impart a constant radial force against the guide member and thus the disc in such manner as to position the guide member in constant engagement with the disc to maintain alignment and prevent rattling of the disc on the hub.

Abstract: The present invention is directed to electrical contacts that comprise spaced electrically conductive particles embedded and bonded into the surface of conductors in which the particles have been kinetically sprayed onto the conductors with sufficient energy to form direct mechanical bonds between the particles and the conductors in a pre-selected location and particle number density that promotes high surface-to-surface contact and reduced contact resistance between the conductors.

Abstract: A steering lock mechanism having an actuator communicating with a lock bolt is provided allowing for more space in the vicinity where a steering wheel is supported by an upper steering shaft. Additionally, a bolt engaging device is supported adjacent a lower end of the upper steering shaft in a position to engage a lock bolt such that any torque forces transmitted through the bolt engaging device will not cause damage to either the device or other components of the steering column. The actuator is rotated about an axis from a first position to a second position to cause the lock bolt communicating with the actuator to advance towards the lower end of the upper steering shaft from a locked position to an unlocked position, respectively.

Abstract: An advance arrangement for use in controlling timing of fuel delivery by a fuel pump comprises an advance piston which is moveable within a first bore and which cooperates, in use, with a cam arrangement of a fuel pump to adjust the timing of fuel delivery by the pump. A surface associated with the advance piston is exposed to fuel pressure within an advance piston control chamber. A light load piston is moveable relative to the advance piston against a spring load due to a light load control spring to adjust the timing under light load conditions. A temperature control valve is operable to control fuel pressure applied to the light load piston depending on engine temperature so as to permit adjustment of the timing depending on engine temperature.

Abstract: A vehicle door latch has a power operated release mechanism for moving a detent from a latched position to a release position comprising a slide that engages the detent at one end and a rotary cam that engages an opposite end of the slide sot that the slide reciprocates when the rotary cam is rotated by an electric motor. The electric motor drives the cam via a concentric gear wheel that has a pin engaging the rotary cam. A forkbolt rotates a rotary block out lever from a by-pass position to a block out position where the block-out lever engages a shoulder of the gear wheel to stop rotation of the gear wheel when the forkbolt is moved to an unlatched position. The vehicle door latch also includes a mechanical override mechanism to rotate the rotary cam to unlatch the vehicle door latch.

Integral retaining tabs are provided for holding the spacer in place on the booster during shipping and installation of the booster. Tubular inserts within the spacer are retained and cushioned against rattling by a thin web of material extending over the end of the insert.

Abstract: A rotary position sensor featuring a magnetized rotor which produces a magnetic flux density that varies sinusoidally with respect to the angular position of the rotor, which may be either a selectively magnetized ring or disk. The magnetic flux density produced by the rotor is measured by a sensor that responds in a linear fashion to the magnitude of the radial component of the magnetic flux density. Typical embodiments would use magnetic flux density sensors, as for example either linear Hall sensors or magnetoresistive type sensors. The measured magnetic flux densities are then used as in a traditional resolver to compute position or used to directly generate control signals to operate, for example, a motor.
