Abstract: A non-contact pressure switch assembly for sensing pressure in, e.g., a vehicle. A piston with integrated magnet in a sensor body is moved under fluid pressure to change a magnetic field in which a Hall sensor is disposed inside the sensor body. The field changes polarity at the Hall sensor at a predetermined piston position.

Abstract: A rotary position sensor measures the relative angular position (within a range of?180°) of a housing or stator and a rotor. The housing carries a galvanomagnetic sensing element and is adapted for fixation to a relatively fixed portion of a host system. The rotor carrying a magnet is disposed for rotation about a fixed axis with respect to the stator and is interconnected to a relatively moving portion of the host system through intermediate linkage. The magnet is juxtaposed in substantially axial alignment with the galvanomagnetic sensing element for magnetic interaction therewith. The housing defines a cavity to receive potting material for encasing the galvanomagnetic sensing element and an adjacent buffer cavity interconnected by a weir, which diverts ant excess potting material into the buffer cavity.

Abstract: A robust, low cost, compact and highly accurate rotary position sensor is disclosed for measuring the relative angular position (within a range ?180°) of a housing or stator and a rotor. The housing carries a galvanomagnetic sensing element and is adapted for fixation to a relatively fixed portion of a host system. The rotor carrying a magnet is disposed for rotation about a fixed axis with respect to the stator and is interconnected to a relatively moving portion of the host system through intermediate linkage. The magnet is juxtaposed in substantially axial alignment with the galvanomagnetic sensing element for magnetic interaction therewith. The housing defines a cavity to receive potting material for encasing the galvanomagnetic sensing element and an adjacent buffer cavity interconnected by a weir, which diverts ant excess potting material into the buffer cavity.

Abstract: A universal anchor for a vehicle, comprising: a magnet being fixedly secured to an anchor portion defining an opening; a flux deflector movably mounted to the anchor for movement in a range defined by a first position and a second position, the flux deflector effectively blocking said opening when said flux deflector is in said first position; a magnet fixedly secured to the anchor; a sensing switch configured to detect the magnetic field of the magnet, wherein the magnetic field is increased as the flux deflector moves from the first position towards the second position, the sensing switch providing a detectable signal when the magnetic field is increased.

Abstract: An improved conventional steering wheel position sensor including a housing, a main gear, an auxiliary gear enmeshed with the main gear and a ring shield at the auxiliary gear. A ring shield wall of the ring shield has a low rise portion adjacent the main gear and a high rise portion distally therefrom. A truncated plate is connected to the high rise portion, and the auxiliary gear is bearingly mounted to an axle of the truncated plate so as to be rotatable without contacting the ring shield.

Abstract: A steering knuckle sensor assembly includes a steering knuckle that forms a central bore and a sensor bore that extends radially from the central bore. A target ring that circumscribes a shaft rotates within the central bore. A speed sensor is disposed in the sensor bore so that it senses the angular speed of the target ring. If the speed sensor is damaged or otherwise fails, it can easily be replaced without the need to replace any other parts within the steering knuckle.
