International Classification:

G01R003/00
US Classification:

29595, 295921, 296021, 216 65, 451 5, 451 41, 361283, 361301
Abstract:

The present invention discloses an inertial sensor having an integral resonator. A typical sensor comprises a planar mechanical resonator for sensing motion of the inertial sensor and a case for housing the resonator. The resonator and a wall of the case are defined through an etching process. A typical method of producing the resonator includes etching a baseplate, bonding a wafer to the etched baseplate, through etching the wafer to form a planar mechanical resonator and the wall of the case and bonding an end cap wafer to the wall to complete the case.

Filed:

Apr 10, 2003
Appl. No.:

10/410744
Inventors:

A. Dorian Challoner - Manhattan Beach CA, US
Kirill V. Shcheglov - Los Angeles CA, US
Assignee:

The Boeing Company - Chicago IL
California Institute of Technology - Pasadena CA
International Classification:

G01C019/00
US Classification:

7350416
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.
