  • Constant current power source electronics for a sensor
    Patent number: 8280694
    Abstract: An apparatus comprises a sensor and a circuit. The sensor is capable of generating a signal in response to detecting a stimulus. The circuit is capable of powering the sensor and providing multiple other capabilities including signal conditioning, non-signal related noise cancellation, and signal transmission using a constant current source power input from a cable and sending the signal over the cable.
    Type: Grant

    Date of Patent: October 2, 2012
    Assignee: The Boeing Company
    Inventors: Richard M. Gratzer, James Robert Underbrink
  • High intensity calibration device
    Patent number: 8107634
    Abstract: A calibration device for calibrating a dynamic pressure sensor includes a power/control box and a portable calibration head disposed in electrical communication with the power/control box. The portable calibration head may include a calibration head housing having a housing opening and a speaker provided in the calibration head housing and communicating with the housing opening. The power/control box may be configured to induce emission of an acoustic calibration signal from the speaker of the calibration head.
