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.
Claims10
An angular acceleration sensing apparatus free of any moving mechanical parts, mechanical linkages, servo mechanisms and the like and operative on a principle whereby relative motion of a volume of fluid contained within a hollow torroid is sensed when a container securable to an object under study is subjected to an angular acceleration about an axis perpendicular to a plane of the torroid, comprising:
- an enclosed circular fluid-filled channel in the form of a torroid rigidly mounted in the container, pairs of thermally sensitive resistive elements suspended within said channel in fixed position, means for maintaining said elements at a constant temperature including an electrical circuit which forces said elements to operate at a preselected resistance corresponding to desired operating temperatue, and means electrically connected with respect to said circuit and said elements to yield signals respresentative of angular acceleration.
