Abstract: A detector for magnetizable materials operates remotely to determine a amplitude and phase modification of an exciting magnetic field caused by the magnetizable materials. These amplitude and phase measurements are used to create a phase-amplitude trajectory in phase amplitude space, which may be finely divided to distinguish among a number of different types of components.

Abstract: A system for controlling multiple vehicle includes a twelve volt (12V)/forty-two volt (42V) battery power distribution system that provides direct current. The system converts single phase alternating current to multiple phase alternating current to simultaneously power multiple vehicle systems. A single pulse width modulation generator converts the direct current from the 12V/42V battery power distribution system to alternating current. This provides one power supply path of alternating current, which has a first phase. A splitter device splits the one power supply path of alternating current into three power paths. A lead/lag circuit is used to shift the alternating current of the second path to a second phase different than the first phase of the first power supply path. A second lead/lag circuit for shifts the alternating current of the third path to a third phase different than the first phase or the second phase. This creates a three-phase alternating current power from a single direct current source.

Abstract: A vehicle drive unit assembly includes an axle extending between a pair of wheels, a braking system for slowing and stopping the vehicle, and a retarding system located on the axle for assisting the braking system. The axle has a housing and an axle shaft that receives input from an engine and driveshaft to drive the wheels. The braking system includes a brake member supported on each of the wheels and an actuator for selectively moving the brake members between an unactuated position and an actuated position. The braking system produces a braking force to slow or stop the rotation of the wheels when the brake is in the actuated position. The retarding system includes a plurality of magnets supported for rotation with the axle shaft and an inductor held fixed to the axle housing. The retarding system produces a retarding force as the magnets rotate with respect to the inductor to slow the rotation of the wheels when the actuator moves the brake members to the actuated position.

Abstract: An AC motor is utilized to drive a closure on a vehicle. The use of the AC motor provides valuable benefits with regard to cost and size. Further, a three-phase AC motor may be utilized, and the pulses in its power supply monitored to determine an obstruction in the path of the closure. Frequency control may also be utilized to provide optimum control of the drive of the component at both start-up and stop.

Abstract: A high temperature superconductor (HTS) synchronous motor or generator includes permanent magnets disposed in the rotor. The permanent magnets can be magnetized after the rotor assembly is manufactured. The permanent magnets reduce flux density perpendicular to the superconducting coil. The magnets can be disposed in the d-axis of the motor. The motor is particularly useful in propulsion applications.

Abstract: An apparatus for controlling multiple vehicle systems includes a single power supply that provides a direct current source. The power supply is comprised of a thirty-six volt (36 V) battery power distribution system. A converter is electrically connected to the power supply to convert direct current to alternating current. A plurality of induction motors are used to operate various vehicle systems. The motors receive alternating current via electrical connections between the converter and the motors. A central processor is connected to relays sending power to each of the motors and provides control signals to the motors based on input from control members used to activate each of the various vehicle systems. At least one sensor is associated with each of the motors to monitor voltage or current of the respective motor and to generate a diagnostic signal that is sent to the processor.

Abstract: A plurality of motors for use in driving accessories on a vehicle, are each powered by three-phase current. A single controller controls the supply three-phase current to the plurality of motors. In another aspect of the invention, pseudothree-phase current is created from a direct current voltage source. A chopping circuit chops the voltage into a plurality of pulses, and a phase shift circuit then creates phase-shifted power signals from those pulses. The present invention thus enables the use of three-phase alternating current motors on a vehicle to drive accessories. This reduces the cost and size of the required motors.

Abstract: A weather strip for use on a vehicle comprises an engaging portion for securing a weather strip to a vehicle and a weather strip body comprising a compressible portion and a magnetic sealing portion. The magnetic sealing portion provides a seal acting in a direction projecting toward a magnetically attractive substrate to provide a sealing interference between the magnetic sealing portion and the substrate when the weather strip is installed on the vehicle and a door closes the opening. The weather strips described herein provide an air and water tight seal without requiring a high compression force, thus improving door operation and reducing closing noise by eliminating the need to slam the door.

Abstract: In the disclosed embodiment of this invention, sets of straight wire bundles are molded or otherwise encased about a cylindrical rotor casing. The straight wire bundles lie parallel to the axis of the cylindrical rotor casing. This process is an alternative to a traditional type of electric motor armature which uses a wire that is coiled around the cylindrical rotor casing. Since the wire bundles are straight and not pulled from a single wire roll, breaking and stretching of the wire is greatly reduced. The straight wire bundles are connected at their ends using a circuit cap to form a complete electrical circuit.
