Abstract

Device suitable for detecting changes of the state of rest or of rectilinear uniform motion of a body, composed of a hollow member (1) rigidly joined to said body and containing one or more mobile elements (2), of suitable means (7) for emitting ultra-sounds of a determinate frequency into the interior of the hollow member, and of suitable transducers (8) for receiving said ultra-sounds, so that by any changes of the state of the body the interior element or elements (2) move relative to the hollow member (1) and cause for this reason a change of frequency of the ultra-sounds picked up by said receiving transducers (8).
