Patent ID: 7405674

Claim:
A circuit for controlling a plurality of light-emitting devices disposed on an object, said circuit comprising: a seamless water-proof and dust-proof enclosure embedded in the object; a motion actuated switch, mounted within the enclosure, for triggering a controller in response to a motion of the object; the controller mounted within the enclosure, the controller comprising a positive pole, a negative pole and a one shot pole, the positive pole electrically coupled to the anode of each of the light-emitting devices and a predetermined voltage source, the negative pole being grounded, the one shot pole coupled to the cathode of each of the light-emitting devices and a shot button coupled among the one shot pole and the negative pole, the controller electrically connected to the motion actuated switch and each of the light-emitting devices for driving the light-emitting devices lighting in a predetermined way when triggered by the motion actuated switch; and a battery, mounted within the enclosure, for supplying said circuit with electrical power; wherein the predetermined way is that the light-emitting devices first lighting separately and sequentially, and then simultaneously flashing N times, N is a natural number; wherein the controller is electrically connected to the light-emitting devices by a plurality of wires and the portion of the enclosure through which the plurality of wires penetrate is sealed by resin or plastic material, such that the circuit is oxidation-free due to the seamless enclosure.
