ABSTRACT:
The Inner-Forcer milli-Hemispherical Resonator Gyro (mHRG) is a small, low cost, high performance gyroscope. It may have an extremely simplified design, with in one embodiment of the present method and apparatus only five major parts total, with most parts filling multiple functions. The method and apparatus in one embodiment may have: a resonator; and a body operatively coupled to the resonator, the unitary body integrally having electrodes, an electrode support unit, a weld ring and a plurality of electrically conductive pins, the plurality of electrodes operatively coupled to the electrically conductive pins.
