Patent ID: 7421897

Claim:
An inertial sensor comprising: at least one substrate; and four sensor elements arranged in a cross-quad configuration substantially in a plane above the at least one substrate, the four sensor elements including: a first sensor element having a first resonator suspended within a first frame; a second sensor element having a second resonator suspended within a second frame; a third sensor element having a third resonator suspended within a third frame; and a fourth sensor element having a fourth resonator suspended within a fourth frame, wherein the first and third frames are configured to move co-linearly along a first axis in the plane, the second and fourth frames are configured to move co-linearly along a second axis in the plane parallel to the first axis, and the frames of at least two pairs of adjacent sensor elements are interconnected by couplings that enable anti-phase movements of the frames but substantially prevent in-phase movements of the frames.
