Abstract: An eddy current brake or retarder device for bringing a vehicle to rest is disclosed. The device includes a stator mounted to a frame of the vehicle, a plurality of poles disposed along a perimeter of the stator, a plurality of coils each wound about each of the plurality of poles, wherein an adjacent pair of poles form an electromagnet when the coil is energized, and a rotor in communication with a transmission axle of the vehicle and located concentric with the stator. A relative rotation of the rotor with respect to the stator produces eddy currents between the poles of the stator and an outer surface of the rotor, causing the rotor to come to a rest.

Abstract: An eddy current braking apparatus is disclosed. The apparatus includes a stator, a coil of wire, and a drum. The stator has a plurality of poles and is mountable to a frame of a vehicle. The coil of wire is wound about each of the plurality of poles and wherein adjacent coils are electrically connected to form an electromagnet. The drum is adapted to receive a wheel and tire assembly and wherein the drum is rotatably mounted to a vehicle axle, and wherein an eddy current is developed between the drum and the stator, from the relative motion of the drum with respect to the stator, thereby retarding rotation of the drum and wheel and tire assembly.

Abstract: A torque biasing device, based on three friction cones and 2 friction rings, can provide differential outputs from a single mechanical input, by varying the interface of the rings to the cones and a speed matching device based on two cones, a friction ring and a clutch can provide smooth clutching operation for a driven shaft.

Abstract: A method and system for detecting faults with a self-exciting sensor includes a monitor circuit coupled to the self-exciting sensor for monitoring a signal associated with the sensor and generating a failure signal. A voltage limiting circuit is coupled to a receiver circuit associated with the self-exciting sensor for generating a first output signal within a valid range of operation in the absence of the failure signal. The voltage limiting circuit also generates a second output signal outside the valid range of operation in response to the failure signal so as to eliminate the necessity of an additional input to control logic associated with the self-exciting sensor.
