Abstract
A gyro includes a rotatable hub with a flexing member centrally supporting a rotor. The rotor is further supported by a pair of piezoelectric force transducers angularly separated by 90 degrees. The rotor turns with the hub. Oscillators drive the transducers and, as the gyro undergoes angular displacement, the oscillators 'follow' the instant natural frequency of the transducers. FM signals are generated which may be resolved into two digital signals indicative of angular rate about the gyro case X and Y axes.
