Abstract
An angular rate sensor having two generally planar proof masses, a drive axis in the plane of the masses, and an input axis perpendicular to the drive axis. The masses are suspended from a sensing frame and constrained for anti-phase movement along the drive axis in drive-mode. The sensing frame is mounted for torsional movement in sense-mode about the input axis in response to Coriolis forces produced by rotation of the masses about the input axis, with sensors responsive to the torsional movement of the sensing frame and the masses about the input axis for monitoring rate of rotation.
