ABSTRACT:
This invention relates to accelerometers for detecting or measuring accelerations. An accelerometer in accordance with the invention includes a member which is caused to vibrate when the accelerometer is subjected to an acceleration above a threshold value. The member is capable of vibrating in more than one plane and, in vibrating, causes a change to occur in a physical parameter of the accelerometer which is other than a dimensional change due to distortion.
