Patent Images
1. an acceleration sensor, comprising:
- a proof mass having minimum amount of mass and maximum surface areas to provide maximized damping of the sensor;
one or more dampers on both side of the proof mass to damp motion of the proof mass;
one or more measuring supports connecting the proof mass to a frame;
said frame connecting the sensor to a subject being measured to measure the acceleration of the subject.

Abstract
A new high G-range damped acceleration sensor is proposed with a proof mass optimized for maximized, bi-directional and symmetrical damping to accommodate acceleration ranges above and beyond several thousand G'"'"'s. In order to achieve the maximum, bi-directional and symmetrical damping, the high G-range acceleration sensor is designed to have minimum amount of mass in the proof mass while maximizing its surface areas. Such high G-range damped acceleration sensor can be applied to any application in which damping (or suppression of ringing) is desired at quite high frequencies.
