摘要：<p>Rate sensor comprising two generally planar proof masses, means for driving the masses to oscillate in phase opposition about parallel drive axes in the planes of the masses, an input axis perpendicular to the drive axes, sense axes perpendicular to the drive axes and the input axis, means mounting the masses for torsional movement about the sense axes in response to Coriolis forces produced by rotation of the masses about the input axis, means constraining the two masses for anti-phase movement about both the drive axes and the sense axes, sensing frames coupled to the masses for movement in response to the torsional movement of the masses about the sense axes, and means responsive to movement of the sensing frames for monitoring rate of rotation about the input axis.</p>
