Abstract
A rotation sensor system is presented. The system comprises a rotating frame configured to be mounted on a gimbal and adapted for controllable rocking motion about a predetermined axis of said frame, and a proof mass assembly mounted on said rotating frame. The proof mass assembly comprises one or more proof mass elements each mounted for controllable movement with respect to the predetermined axis along a certain path, a distance of each proof mass element from said axis corresponding to a direction of the rocking motion of said frame, thereby affecting a moment of inertia of said rotating frame.
Claims21
A rotation sensor system comprising a rotating frame configured to be mounted on a gimbal and adapted for controllable 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 for controllable 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.
A structure comprising a rotatable frame and one or more movable proof mass elements elastically connected to said frame, the structure is configured to enable displacement of said one or more proof mass elements along a predetermined path thereby varying a mass distribution of the structure with respect to an axis of rotation of said frame.
