DEFINITION

Classification: 340/463

External alarm or indicator of movement:

(under subclass 425.5) Subject matter including external signalling systems which automatically respond to a state of motion (e.g., turning, acceleration, deceleration, backing) of the vehicle and which communicate with persons outside the vehicle (e.g., other drivers, pedestrians).

(1) Note. The state of motion may be sensed directly, as by an accelerometer, or it may be sensed by devices responsive to the activation of a system which causes the movement (e.g., the steering linkage or the transmission gear selector).
