Abstract:
1. A gyroscope, comprising: a central anchor; a sense frame disposed around the central anchor; a plurality of sense beams configured for connecting the sense frame to the central anchor; a drive frame disposed around and coupled to the sense frame, the drive frame including a first side and a second side; pairs of drive beams disposed on opposing sides of the sense frame, the drive beams configured to drive the first side of the drive frame in a first direction along a first axis substantially in the plane of the drive frame, the drive beams being further configured to drive the second side of the drive frame in a second and opposing direction along the first axis; a drive frame suspension configured to substantially restrict a drive motion of the drive frame to that of a substantially linear displacement along the first axis, wherein the drive frame suspension includes a plurality of flexures, each flexure of the plurality of flexures configured for coupling a pair of drive beams to the drive frame; and a sense frame suspension configured to be compliant to rotation around a second axis orthogonal to the first axis, the sense frame suspension configured to resist translational motion along the first axis.
