Method For Fabricating A Tuning Fork Gyroscope
US Patent:
7172919, Feb 6, 2007
Filed:
Oct 20, 2004
Appl. No.:
10/970067
Inventors:
Marc S. Weinberg - Needham MA, US
Anthony S. Kourepenis - Acton MA, US
William D. Sawyer - Lexington MA, US
Jeffrey T. Borenstein - Holliston MA, US
James H. Connelly - Weymouth MA, US
Amy E. Duwel - Cambridge MA, US

Assignee:
The Charles Stark Draper Laboratory, Inc. - Cambridge MA
International Classification:
H01L 21/00
US Classification:
438 50, 438 51
Abstract:
A method for reducing errors in a tuning fork gyroscope includes determining a first distance, g, between an upper sense plate and a proof mass and a second distance, g, between a lower sense plate and the proof mass. The method further includes applying a first voltage, V, to the upper sense plate and a second voltage, V, to the lower sense plate, wherein the ratio of the first voltage and the second voltage is a function of the first distance and the second distance.

International Classification:
G01C019/00
US Classification:
073/504160
Abstract:
A tuning fork gyroscope typically including at least one proof mass with an upper sense plate disposed above the proof mass and a lower sense plate disposed below the proof mass and means for sensing changes in the nominal gaps between the sense plate and the proof mass and for outputting a signal indicative of the gyroscope angular rate.
