  • Patent number: 5653462
    Abstract: An occupant position sensor utilizing either ultrasonic, microwave or optical technologies, or seatbelt spool out and seat position sensors, are used as inputs to the primary vehicle crash sensor circuit to permit the longest possible sensing time before the occupant gets proximate to the airbag and is in danger of being injured by the deploying airbag. The sensor further disables the inflatable restraint system if the occupant is in danger of being injured by the system deployment. Separate systems are used for the driver and passenger to permit the optimum decision to be made for each occupant.

  • Patent number: 4700260
    Abstract: A mounting and retaining assembly for a degaussing coil and ground strap for use on a cathode ray tube includes a flexible wire form that is held in place by the tube tension band. The wire is bent to form separate regions that receive the degaussing coil and ground strap. When the degaussing coil and ground strap are in place, the wire is under tension which holds the degaussing coil and ground strap firmly against the rear surface of the tube. The mounting and retaining assembly also includes retaining clips that cooperate and are held in place by the tube mounting lugs. The clips incorporate retaining loops that also receive and retain the degaussing coil and ground strap at other points.

  • Patent number: 4500923
    Abstract: In a power supply for a remote controlled television receiver, a bridge rectifier includes first and second unidirectional current conducting devices, an output terminal, a current return terminal and two input terminals. A remote control circuit generates an on/off command signal. A source of alternating voltage available during both states of the command signal is coupled between the two input terminals. A first direct voltage is developed between the output and current return terminals during both the on and the off states of the command signal upon alternate conduction of the two unidirectional current conducting devices. A first power supply is coupled between the bridge rectifier output and current return terminals and is responsive to the command signal for developing an operating potential from the first direct voltage only during the on-state of the command signal. A load circuit is energized by the operating potential to draw power from the bridge rectifier output terminal.
