US Patent 7501595 Self-compensating motion detector

Apparatus and method for activating a passive entry system. The motion detector can include a latch input lever, a switch, and a damper. The damper can provide more resistance to the latch input lever in order to transfer motion to the switch in response to fast movement of the door handle. In some embodiments, the motion detector can include a switch actuator, a notched lever, and a switch. Movement of the notched lever can cause the switch actuator to contact the switch. In other embodiments, the motion detector can include a switch actuator, a notched lever, and a magnetic sensor switch. The magnetic sensor switch can include a magnetic switch member that moves in response to a second end of the switch actuator in order to complete a circuit to the passive entry system.
