  • Bulk acoustic wave gyroscope with spoked structure
    Patent number: 9970764
    Abstract: A Coriolis-based bulk acoustic wave gyroscope includes a center-supported resonating element with capacitively-coupled drive, sense, and control electrodes. The resonating element has a first substantially solid or perforated region which is connected to the center-support by a second region characterized by a plurality of spokes or beams. When operating in a resonance state, the first region undergoes a bulk acoustic mode of vibration while the second region undergoes a flexural mode of vibration. Energy losses associated with the flexural mode of vibration reduce the overall quality factor (Q) at high resonance frequencies creating a large bandwidth and a fast response time without needing vacuum.

  • Method and apparatus for self-calibration of gyroscopes
    Patent number: 9915532
    Abstract: A gyroscope having a resonant body utilizes a self-calibration mechanism that does not require physical rotation of the resonant body. Instead, interface circuitry applies a rotating electrostatic field to first and second drive electrodes simultaneously to excite both the drive and sense resonance modes of the gyroscope. When drive electrodes associated with both the drive and sense resonance modes of the gyroscope are excited by forces of equal amplitude but 90° phase difference, respectively, the phase shift in the gyroscope response, as measured by the current output of the sense electrodes for each resonance mode, is proportional to an equivalent gyroscope rotation rate.
