    • An inertial sensor is described that has means for improving quadrature rejection The sensor is of a ring type, driven by a driver circuit, the sensor further comprising primary and secondary portions having corresponding signal pickoffs. The primary pickoff signal amplitude is controlled via an automatic gain control, the primary phase lock loop and VCO locks to the resonant frequency to provide the clocks for the synchronous detectors, the primary pickoff signals via the primary phase shift circuit is provided to the primary driver, the secondary pickoff signal being input into a detector circuit capable of detecting motion in the sensor. The secondary channel comprises a series of circuits that when operable in series significantly improve the quadrature rejection ability of the sensor. The circuits include a synchronous detector, passive and active filters and a decimator.

    • An angular rate sensor has a ring, a plurality of sensor-drivers, circuitry, a controller, an energy sensor, and an output signal generator. The sensors-drivers may be capacitors, inductors, or a sensor having a piezoelectric material. The sensor-drivers each have a component that vibrates along with the ring, and the sensor-drivers are arranged in cooperating sets, each cooperating set having two sensor-drivers positioned 180º apart. The circuitry can selectively engage some of the cooperating sets as sensors and others of the cooperating sets as drivers. Those sets used as sensors sense motion of the ring. Those sets used as drivers apply forces to the ring. Some of the drivers cause the ring to vibrate at its natural frequency, and some of the drivers seek to inhibit motion of the ring at particular locations. Locations at which drivers seek to inhibit motion are those locations that would be nodes in the absence of angular motion.
