An accelerometer, comprising a main body (2), acceleration responsive means (1) mounted from the main body in such manner as to be movable on application to the accelerometer of acceleration along a single direction (A-B) or about a single axis, sensor means (8, 9, 10) for sensing the magnitude and sense of any such movement of the acceleration responsive means relative to the main body and for providing output characteristic of the such movement; means for producing from the sensor output digital signals (12, 15); means (12, 18) for deriving from the digital signals control signals which are utilisable to operate means (5, 6) for applying force to the responsive means (1) to counteract said movement, and means for producing output signals characteristic of the applied forces. |
