Abstract: An Automatic Long-Life Infrared Emitter & Locator System which may be used to locate persons in need of assistance or marked objects is disclosed. Since the emitter (10) operates continuously and emanates infrared radiation (21) that can not be seen by the user, no affirmative action is required to activate the emitter (10). One of the preferred embodiments of the present invention (10) includes a flexible plastic or rubber housing (12) having an opening (15) that is specially shaped to fit over and to finly grasp a conventional electrical battery (16). A lens (18) residing on the top of the housing (12) passes invisible energy issuing from an infrared emitting diode (20) deployed beneath it. The diode (20) is connected to the battery (16) by leads (19) through a pulse control circuit (22). This circuit (22) produces intense and regular spikes of energy that cause the diode (20) to flash over a period of many weeks.
