G01P - Definition
This subclass covers:
Means to measure linear or angular rate of change of position of solid bodies or fluid mediums (speed, velocity);
Means to measure rate of change of linear or angular speed or velocity (acceleration, deceleration, shock) of solid bodies or fluid mediums;
Means to indicate or record movement of solid bodies or fluid mediums (presence, absence or direction); and
Means to test or calibrate apparatus or devices covered by this subclass.
