Abstract: A finger mounted laser spotlight is constructed of a near-infrared continuous wave laser diode powered by a miniature power supply powered in turn by a nine volt battery. The laser diode is mounted inside a cylindrical heat sink housing which includes a focusable lens assembly. A momentary switch is connected in-between the power supply and battery. Cables interconnecting the components are sized to preselected lengths so that, when the power supply and battery are positioned over a wrist or other portion of the arm behind the fingers, the laser diode and housing are positioned over an index finger and the momentary switch is positioned between a thumb and index finger. In use, the momentary switch is pressed and held to provide a beam of near-infrared light.

Abstract: The Locator Beacon (LB) is an 18 inch diameter hemispherical unit designed to be air dropped via parachute from a search aircraft near an aircraft crash site. The LB is self uprighting when it lands on the ground and its antenna is always oriented for maximum efficiency. When activated, the LB sends out a radio frequency signal on 121.6 Mhz and 243.2 Mhz, this signal can be tracked by aircraft or by ground parties equipped with directional locating equipment. The LB also contains a strobe light beacon to aid in visual acquisition of the unit. The LB remains in the active (broadcast) mode for approximately 20 minutes before resetting itself to the listening mode. External VHF activation of the LB repeats the LB broadcast and strobe light cycle for another 20 minutes.
