Embodiment Construction

[0045] Before beginning the detailed description of the concepts, techniques and systems of the invention described herein, a general discussion of conventional techniques and A review of problems with search aids and other methods such as smoke signals, whistles and flashes can be useful.

[0046] Search and rescue efforts to locate victims such as downed pilots and / or men overboard (MOB) often encounter environmental and procedural obstacles. In particular, obstacles and surface features of the search environment can hinder rescue efforts. For example, rough surf on the ocean, rough terrain on land, inclement weather (including rain and fog), and distance can all obstruct direct line of sight from the locator to the victim that is necessary to locate the victim. Other surface features, such as white spray on the waves, can obscure victims, making them particularly difficult for rescue teams to spot, during so-called "change-of-direction" operations when search ships turn ar...

Abstract

A system includes an ultraviolet c-band radiation detector to enable detection of radiation during search and rescue operations, at least a portion of the radiation including ultraviolet c-band radiation, and a stimulus generator configured to generate a stimulus in response to detected ultraviolet c-band radiation. Further embodiments may include multiple synchronized ultraviolet c-band detectors to enhance system sensitivity and facilitate detection of relatively weak radiation sources, relatively distant sources, and/or radiation scattered about an environment.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of US Patent Application No. 12 / 554,527, entitled "SEARCH AND RESCUE USING ULTRAVIOLET RADIATION," filed September 4, 2009, the entire contents of which are incorporated herein by reference. Background technique [0003] As known in the art, ultraviolet (UV) light is electromagnetic radiation having a wavelength shorter than that of visible light but longer than that of x-rays. UV light includes wavelengths in the range of 100 nanometers to 400 nanometers (nm) and energies from 3 electron volts to 124 electron volts. UV light is emitted by the sun, electric arcs, and artificial sources such as invisible light. As ionizing radiation, UV sources are capable of causing chemical reactions that cause many substances to luminesce or fluoresce. Although UV light is invisible light, most people realize the effects of UV radiation through sunburn. However, the UV spectrum has many oth...
