发明名称 Self-calibrating accelerometer
摘要 The method and apparatus in one embodiment may have: a sensing element for an accelerometer having a bias, the sensing element having a rectangular plate supported by flexures which allow rotation about a transverse center line thereof; a center of mass (CG) of the sensing element having two stable positions, one on each side of an axis of rotation defined by a centerline of suspension; a secondary mass within a proofmass translates in-plane to move the center of mass to thereby effect a self-calibration mechanization that continuously measures and nulls the accelerometer's bias under dynamic operating conditions.
