Time Domain Switched Ring/Disc Resonant Gyroscope

摘要

A system includes a circular oscillator suspended by a flexible support structure to a support frame, a drive mechanism configured to induce the circular oscillator into a two-dimensional drive oscillation, where the drive oscillation is modified responsive to a sense oscillation of the circular oscillator caused by an angular rotation of the support frame and the circular oscillator, and a plurality of digital proximity switches disposed around a perimeter of the circular oscillator. During the modified drive oscillation a plurality of the digital proximity switches are configured to switch between an open state and a closed state and generate a time and position output to allow for a determination of each of a plurality of variable oscillation parameters for each oscillation of the modified drive oscillation.
