Abstract
A sensing frame that moves in response to torque generated by the Coriolis acceleration on a drive subsystem is disclosed. The sensing frame include a first rail. The first rail is constrained to move along the first axis parallel to the first rail. The frame includes a second rail substantially parallel to said first rail. The second rail is constrained to move along the first axis. The frame includes a base and at least two guiding arms for ensuring that the first rail and the second rail move in anti-phase fashion along the first axis. A first guiding arm is flexibly coupled to the first rail and flexibly coupled to the second rail and a second guiding arm is flexibly coupled to the first rail and flexibly coupled to the second rail. The first guiding arm is flexibly suspended to the base at a first anchoring point for allowing rotation of the first guiding arm around the second axis that is perpendicular to the first axis and normal to the plane, and the second guiding arm is suspended to the base at a second anchoring point allowing rotation of the second guiding arm around the third axis parallel to the second axis. The sensing frame includes a plurality of coupling flexures …
