(under subclass 1.37) Subject matter wherein the device being proven or calibrated comprises an inertial member having an
intrinsic or relational property which changes in response to a time rate of change of speed or velocity of a body which can be used to measure acceleration.
SEE OR SEARCH THIS CLASS, SUBCLASS:

504.03, for using gyroscopic or Coriolis effect on an inertial element to determine both angular rate and linear acceleration.
652+, for an apparatus sensing vibrations by use of an inertial member.
866.2, for a process or an apparatus for measuring a time rate of change in a sensed condition not provided for elsewhere. SEE OR SEARCH CLASS
116, Signals and Indicators,
28+, for a mechanical indicator, per se, which provides a humanly perceptible signal in response to acceleration and includes no quantitative measuring means.
