ABSTRACT:
An angular acceleration sensing device which operates on a principle whereby the relative motion of a volume of gas or fluid contained within an annular ring or torroid is sensed when the container is subjected to an angular acceleration about an axis perpendicular to the plane of the fluid ring. The apparatus includes an enclosed circular fluid-filled channel which can be an annular ring or torroid; thermally sensitive elements suspended within the fluid channel and an electronic circuit providing power to the sensing elements and output voltages.
