Abstract

An electromagnetic radiation (EMR) emitting device in the infrared range utilizing a glass coated microwire with a non-sealed housing.

Description

ELECTROMAGNETIC RADIATION EMITTING DEVICE

FIELD OF THE INVENTION

The present invention relates to an electromagnetic radiation (EMR) emitting device, and in particular to a device emitting electromagnetic radiation in the infrared range utilizing a glass coated microwire with a non-sealed housing configured to promote heat dissipation generated by said EMR emitting source.

BACKGROUND OF THE INVENTION

There are many known applications for positional marking where the position of various objects, sites, an area of interest, the position of an individual or a group of individuals or the location of some unit(s) or equipment, are marked such that they are readily visible either day or night.

However, there are many application where non-visible or discrete positional marking is required. For example, discrete positional marking of various individuals, objects, or area is often required for tactical reasons. Such non-visible marking allows other, select, individuals and/or units to observe and detect the discrete position. This is particularly advantageous in a non-visible environment where friendly forces need to be readily identifiable to one another and to further allow for various coded communication in a discrete manner without the use of visible light. Such discrete marking and/or communication may prevent detection by an unfriendly or unauthorized observer, or to discern between different subgroups within a common friendly force. Other applications include search and rescue missions both for military and civilian uses, to identify individuals.

Devices for such discrete positional marking, indicating the presence of an object without the use of light in the visible range, are known in the art. Such devices rely on generating electromagnetic radiation having wavelengths in the Infrared Radiation (IR) range. Such IR generating devices have a complementary and/or corresponding device capable of detecting the generated IR signal so as to render it visible.

Infrared lighting systems are ideally suited for this purpose since they are not visible to the naked eye, but such lighting systems may be clearly seen by anyone using devices sensitive to IR, for example night vision goggles, or thermal cameras. Glass coating of microwires have been known in the art since as early as 1928, when Taylor was granted US patent 1,793,529 entitled “Process and apparatus for making filaments”. Applications for microwires include heating elements, infrared (IR) emitters, security tags, and the like.

U.S. Patent 4,912,224 to Andersen, teaches a near infrared aircraft lighting system for use on the exterior of aircraft in combination with an existing visible light beacon.

U.S. Patent 5,804,829 to Palmer et al., teaches a near infrared signal beacon, which provides a visual location signal during poor light conditions.

U.S. Patent 5,225,828 to Walleston et al., teaches a device for alerting friendly personnel on land, sea or air. The beacon includes at least one near infrared light emitting diode and a visible light emitting diode.

U.S. Patent 5,414,405 to Hogg et al., teaches a device including a NIR LED contained within a housing. The device is adapted to be carried externally by a person or an object, such as vehicles, and enables, for example, to distinguish friend from foe in dark conditions.

U.S. Patent 5,939,726 to Wood et al., entitled “Infrared radiation source”, is directed to a pulsable IR radiation source.

US Patent 8,508,128 to Tidhar, teaches a thermal radiation marker adapted to emit radiation within the thermal portion of the infrared spectrum, using an incandescent filament with a glass or quartz enclosure, where the enclosure features pressurized inert gas.
