ABSTRACT:
An apparatus in one example comprises a vibrating beam, a first drive component, and a second drive component. The first drive component for a first time period oscillates the vibrating beam in a first direction to sense angular rate of the vibrating beam. The second drive component for a second time period oscillates the vibrating beam in a second direction to sense angular rate of the vibrating beam.
