  • Publication number: 20110015804
    Abstract: A system and method are provided for communicating data synchronously with a plurality of crash sensors onboard a vehicle. The system includes a control unit comprising interface circuitry for communicating with a plurality of crash sensors and providing synchronization signals to the crash sensors. The system also includes a communication bus coupled to the control unit for communicating with the crash sensors. The system further includes a plurality of crash sensors connected to the communication bus for communicating with the control unit. Each of the plurality of crash sensors receives one or more synchronization signals and is capable of transmitting data in response to the synchronous signals. The plurality of crash sensors each comprises logic for comparing a sensed parameter to a threshold and transmitting data when the sensed parameter exceeds the threshold.

  • Patent number: 5631602
    Abstract: An amplifier circuit and method of providing diagnostic testing to a Wheatstone bridge amplifier circuit are provided herein. The amplifier circuit includes a balanced circuit such as a Wheatstone bridge employed in a piezoresistive transducer which produces a differential output signal. The amplifier circuit also includes an amplifier having a differential input for amplifying differential input signals. A diagnostic test circuit is coupled between the balanced circuit and the amplifier circuit and includes a pair of resistors with current sources which may be switched in via electronic switches. With the current sources switched in, a known offset voltage is applied across the differential input to the amplifier and the amplifier output is monitored and compared to an initial output signal. By comparing the initial output signal with the test signal, a determination as to the gain and other characteristics of the amplifier circuit can be made.

  • Patent number: 4894015
    Abstract: A flexible circuit interconnector connects a circuit board having a ceramic substrate to pin connectors at the connector end of a circuit board connector housing. The interconnect has a thin flexible sheet of polymeric, electrical insulating material with a mating end and a connector end. The mating end includes a plurality of spaced holes therethrough for receiving tail ends of the pin connectors. A plurality of electrically conductive runners provided on one side of the flexible sheet electrically connect the pin connectors to printed conductors on the ceramic substrate. The thin flexible sheet has a viewing slot at the connector end thereof which is bridged by the runners and it has a bend which accommodates differential thermal expansion in the circuit board and connector.
