ABSTRACT:
Rate sensor having a plurality of generally planar masses, a drive axis in the planes of the masses, an input axis perpendicular to the drive axis, and sense axes perpendicular to the drive axis and the input axis. The masses are driven to oscillate about the drive axes and are mounted for torsional movement about the sense axes in response to Coriolis forces produced by rotation of the masses about the input axis, with sensors responsive to the torsional movement about the sense axis for monitoring rate of rotation.
