  • Patent number: 7897978
    Abstract: A tilt sensor includes a body; a first emitter and a first receiver being spacedly disposed on the body, the first receiver being used for receiving a first signal emitted from the first emitter, a second emitter and a second receiver being spacedly disposed on the body, the second receiver being used for receiving a second signal emitted from the second emitter, and an arm rotatably secured on the body. As the tilt sensor device is in a first tilt state, the arm blocks the first receiver to receive the first signal. As in a second tilt state, the arm blocks the second receiver to receive the second signal. As in a third tilt state, the arm blocks none of the first receiver and the second receiver to receive the first signal and to receive the second signal respectively.
