    摘要: An angular velocity sensor including a drive extension mode. In one aspect, an angular rate sensor includes a base and at least three masses disposed substantially in a plane parallel to the base, the masses having a center of mass. At least one actuator drives the masses in an extension mode, such that in the extension mode the masses move in the plane simultaneously away or simultaneously towards the center of mass. At least one transducer senses at least one Coriolis force resulting from motion of the masses and angular velocity about at least one input axis of the sensor. Additional embodiments can include a linkage that constrains the masses to move in the extension mode.

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 connecting said sensing frame to the drive subsystem and a transducer for sensing motion of the first and second rails responsive to said angular velocity.
