Microfabricated Cantilever Slider With Asymmetric Spring Constant

View page
US Patent:
8274200, Sep 25, 2012
Filed:
Nov 19, 2008
Appl. No.:
12/274312
Inventors:
Huantong Zhang - Long Beach CA, US
Daniel Hyman - Long Beach CA, US
Assignee:
XCOM Wireless, Inc. - Signal Hill CA
International Classification:
H01L 41/08
US Classification:
310330, 310331, 310332, 200181
Abstract:
Mechanical springs and sliders as used in microfabricated actuators to provide an asymmetric spring constant are described. The asymmetric spring constant provides a propensity for deflection towards one direction, and a propensity for separation (i. e. restoration) towards the other direction. The asymmetry and slider system provides a passive mechanical means to achieve faster switching times and higher switch restoring forces.

US Patent:
20200408524, Dec 31, 2020
Filed:
Jun 26, 2019
Appl. No.:
16/452967
Inventors:
- Coppell TX, US
Deyou FANG - Frisco TX, US
David MCCLURE - Carrollton TX, US
Huantong ZHANG - Coppell TX, US
Naren K. SAHOO - Frisco TX, US
Assignee:
STMicroelectronics, Inc. - Coppell TX
International Classification:
G01C 19/5719
H04L 27/38
Abstract:
A microelectromechanical system (MEMS) gyroscope sensor has a sensing mass and a quadrature error compensation control loop for applying a force to the sensing mass to cancel quadrature error. To detect fault, the quadrature error compensation control loop is opened and an additional force is applied to produce a physical displacement of the sensing mass. A quadrature error resulting from the physical displacement of the sensing mass in response to the applied additional force is sensed. The sensed quadrature error is compared to an expected value corresponding to the applied additional force and a fault alert is generated if the comparison is not satisfied.
