Patent Images
1. A resonator gyroscope, comprising:
- an isolated resonator including a counterbalancing plate and a proof mass;
one or more double beam flexures each interconnecting the counterbalancing plate and the proof mass with a first and a second beam attached to the proof mass and a third and a fourth beam attached to the counterbalancing plate; and
a baseplate affixed to the resonator by the one or more double beam flexures;
wherein the counterbalancing plate and the proof mass transfer substantially no net momentum to the baseplate when the resonator is excited.

Abstract
The present invention discloses a gyroscope comprising an isolated resonator including a post proof mass and counterbalancing plate. One or more double beam flexures each interconnect the counterbalancing plate and the proof mass with a first and a second beam attached to the post proof mass and a third and a fourth beam attached to the counterbalancing plate. A baseplate is affixed to the resonator by the double beam flexures. The counterbalancing plate and the proof mass transfer substantially no net momentum to the baseplate when the resonator is excited.

22. A method of producing a resonator gyroscope, comprising the steps of:
-
providing an isolated resonator including a counterbalancing plate and a proof mass;
interconnecting the counterbalancing plate and the proof mass with one or more double beam flexures where each attach to the proof mass with a first and a second beam and each attach to the counterbalancing plate with a third and a fourth beam; and
affixing a baseplate to the resonator by the one or more double beam flexures;
wherein the counterbalancing plate and the proof mass transfer substantially no net momentum to the baseplate when the resonator is excited. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
