DEFINITION

Classification: 73/514.31

Inductive or magnetic sensor (e.g., Hall effect sensor):

(under subclass 514.16) Subject matter wherein the sensing means comprises: (a) a magnetic body which produces an electromotive force in a circuit or a circuit element wherein the electromotive force is varied by the change in the property of the inertial member due to an acceleration of the body or (b) a body whose magnetic characteristic changes in response to the change in the property of the inertial member due to the acceleration of the body.
