(under subclass 160) Subject matter including means producing an electrical signal representative of the time rate of change of speed or a physical object.
(1) Note. This subclass relates to electrical accelerometers other than, for example, those which sense acceleration by means of an inertial element.
(2) Note. The means of this subclass may include means responsive to acceleration, per se, or means responsive to a speed signal to derive the acceleration.
