ABSTRACT:
This invention relates to accelerometers, that is to devices for detecting or measuring accelerations. An accelerometer in accordance with this invention includes at least one body a support or support system for supporting the body in a state of stable equilibrium except when the accelerometer is subjected to an acceleration exceeding a threshold value wherein movement of the body relative to the support causes a change in a physical parameter of the accelerometer which is other than a dimensional change due to distortion and other than, or in addition to, a flow of electric current via the body from one part of the support to another.
