DEFINITION

Classification: 73/514.01

Acceleration determination utilizing inertial element:

(under subclass 488) Subject matter comprising an inertial member having an intrinsic or relational property which changes in response to a rate of change of speed of a body and which can be used to measure acceleration.

(1) Note. An inertial sensor responsive to a rate of change in speed and not elsewhere classified is located here.
