Low profile angular rate sensor assembly.

摘要

A low profile angular sensor assembly (10) having a base member (12) adapted for rotation about a spin axis and a generally planar gyroscopic element (18) resiliently coupled to the base member for rotation therewith and for pivotal movement relative to the base member about a pivot axis (35) orthogonal to the spin axis also includes a planar piezoelectric beam (40) which is coupled to the base member and to the gyroscopic element so that it is substantially parallel to the gyroscopic element. The coupling (52) is selectively compliant to isolate the piezoelectric beam from motion in the plane of the beam.
