ABSTRACT:
A rate measuring instrument uses acoustic energy transmitted through a crystalline media (41) to sense rate. Acoustic energy travels along a path (1-31) within the crystalline media and impinges upon an output transducer (45) at an established point after being reflected a number of times from facets (47) of the crystalline media (41). Rate information is detected as a shift in the point of impingement of the greatest amount of acoustic energy upon the output transducer (45).
