Compliant structures with time-varying moment of inertia
First Claim
1. A rotation sensor system comprising a rotating frame configured to be mounted on a gimbal and configured to be driven in controlled rocking motion about a predetermined axis of said frame, and a proof mass assembly mounted on said rotating frame, said proof mass assembly comprising one or more proof mass elements each mounted to be driven into controlled movement with respect to said predetermined axis along a certain path, a distance of the proof mass elements from said axis corresponding to a direction of the rocking motion of said frame, thereby affecting a moment of inertia of said rotating frame.

Abstract
A rotation sensor system is presented. The system includes a rotating frame configured to be mounted on a gimbal and configured to be driven for controlled rocking motion about a predetermined axis of the frame, and a proof mass assembly mounted on the rotating frame. The proof mass assembly includes one or more proof mass elements, each mounted to be driven into controlled movement with respect to the predetermined axis along a certain path, such that a distance of each proof mass element from the axis corresponding to a direction of the rocking motion of the frame, thereby affecting a moment of inertia of the rotating frame.
