.~ Angular rate using wave or beam motion (e.g., Sagnac type)
DEFINITION
Classification: 73/504.01
Angular rate using wave or beam motion (e.g., Sagnac type):
(under subclass 488) Subject matter including means producing a wave or a beam and wherein the wave or beam is propagated about an axis of rotation and the determination of the time rate of change in position of the body is made by measuring a parameter (e.g., phase) of the wave or beam.
(1) Note. The waves of this subclass includes acoustic, electron, entropy, ionic, electromagnetic waves, or microwaves.

514.28, for measuring acceleration of a body by modifying a change in a characteristic of a surface acoustical wave in accordance with a change in a property of an inertial mass due to acceleration of the body.
570+, for measuring or testing by vibration, per se.
