  • Method for fabricating a tuning fork gyroscope
    Patent number: 7172919
    Abstract: A method for reducing errors in a tuning fork gyroscope includes determining a first distance, gt, between an upper sense plate and a proof mass and a second distance, gb, between a lower sense plate and the proof mass. The method further includes applying a first voltage, Vt, to the upper sense plate and a second voltage, Vb, to the lower sense plate, wherein the ratio of the first voltage and the second voltage is a function of the first distance and the second distance.

  • Tuning fork gyroscope
    Patent number: 6862934
    Abstract: A tuning fork gyroscope typically including at least one proof mass with an upper sense plate disposed above the proof mass and a lower sense plate disposed below the proof mass and means for sensing changes in the nominal gaps between the sense plate and the proof mass and for outputting a signal indicative of the gyroscope angular rate.
