A bistable sensor with a tunable threshold for use in microelectromechanical systems. The sensor uses electrostatic force to modify the threshold and to disable the sensor in a deflected position once a sustained extreme in vibration is detected. Potential applications include mechanical implementations...http://www.google.com/patents/US6327909?utm_source=gb-gplus-sharePatent US6327909 - Bistable mechanical sensors capable of threshold detection and automatic elimination of excessively high amplitude data
