  • Vibrating accelerometer-multisensor
    Patent number: 4744249
    Abstract: A vibrating multisensor, each using two accelerometers which are vibrated along straight lines perpendicular to their sensing axes. In one embodiment, the sensing axes are co-linear, and in another embodiment the sensing axes are perpendicular. The accelerometers preferably use a proof mass and flexure suspension made on a silicon wafer sandwiched between two other wafers that carry electrodes both for sensing displacement and forcing of the central accelerometer wafer.
    Type: Grant
    Filed: July 10, 1986
    Date of Patent: May 17, 1988
    Assignee: Litton Systems, Inc.
    Inventor: Robert E. Stewart
  • Vibrating accelerometer-multisensor
    Patent number: 4744248
    Abstract: A vibrating multisensor, each using two accelerometers which are vibrated along straight lines perpendicular to their sensing axes. The sensing axes are co-linear, the accelerometers are vibrated in phase opposition along parallel axes. The accelerometers preferably use a proof mass and flexure suspension made on a silicon wafer sandwiched between two other wafers that carry electrodes both for sensing displacement and forcing of the central accelerometer wafer.
