  • Patent number: 6141620
    Abstract: A system for remote testing of a plurality of vehicles on a test track includes a plurality of guide wires and position transponders embedded in the track. Each vehicle to be tested includes an onboard vehicle controller (VCON) which in turn includes various servo components for operating the steering wheel, shift lever, brake and accelerator pedals of the vehicle. A base computer receives desired missions from an operating computer, and the base computer loads a respective mission into each VCON via an rf link. Then, the base computer monitors the vehicles for proper, safe operation. The VCONs execute the missions loaded by the base station and periodically report their status to the base computer.

  • Patent number: 5965960
    Abstract: A programmable, electronic switch system in which the upper and lower limits of travel of a moving device can be stored in the memory of a circuit. Once the upper and lower limits of travel have been programmed into the circuit, movement of the device causes a variable voltage to be output to the circuit. The variable voltage is compared against the upper and lower limits to determine if the voltage is within the range between the upper and lower limits or outside of one or either of the upper and lower limits.

  • Patent number: 5946644
    Abstract: A shaft position indicator in which a collar is formed on and moves on in accordance with a shaft. The collar is placed opposite an optical sensor and includes a notch which activates an optical sensor when the notch is located opposite the sensor. When the notch is opposite the sensor, a driving circuit outputs a voltage. When the notch is not opposite the sensor, the driving circuit outputs 0 voltage. The light source and sensor are placed a distance from the collar equal to the focal length to substantially eliminate interference from ambient light.

  • Patent number: 5906647
    Abstract: A right inductive coil is coupled to a vehicle at a first location offset from the vehicle's centerline for generating a first signal in response to an electromagnetic signal in a guide wire beneath the vehicle. Similarly, a left inductive coil coupled to the vehicle opposite the right coil relative to the centerline for generating a second signal in response to an electromagnetic signal in the guide wire. A signal comparator receives the signals and generates a guidance signal representative of the combination of the signals. Also, a position antenna is movably mounted in the vertical dimension on the vehicle for generating query pulses and detecting echo pulses from transponders embedded in a test track.

  • Patent number: 5602450
    Abstract: An apparatus for remotely operating an ignition switch mounted on the steering column of an automobile includes a motor mounted on the floor or other surface of the automobile away from the steering column, such that the steering column does not bear the weight of the motor. A drive cable is connected to the motor, and the drive cable is also connected to a coupling which is mounted on the steering column and which is connected to the ignition switch. The coupling translates rotational motion of the drive cable 90.degree., so that the coupling and drive cable do not unduly project straight out from the steering column and hence do not interfere with other components, e.g., shift levers, that are mounted on the steering column. A position sensor generates a signal representative of the position of the ignition switch, and the signal is received by a controller. In turn, the controller activates the motor as necessary to establish and/or maintain a desired position of the ignition switch.
