Multiple uses abound for infrared radiation technology. Most of its uses have to do with electronics and computers. It is a way to power electrical things without wires and cables. It is an alternate form of wireless communication. Its applications work well for the disabled and have a large number of advantages over radio and ultrasound waves.

Car locking systems, computer mice, keyboards, floppy disk drives, printers, emergency response systems, windows, doors, lights, curtains, beds, radios, headphones, security and navigation systems, signage, telephones, toys, CD players, stereos, VCRs and TVs all use this technology. In some ways, it is much more dependable than other forms of wireless communication.

Some of infrared advantages are infrared has low power requirements, low circuitry costs and easy connections, higher security, portable, international compatibility, and less interference from other electronics. With this technology, security grows because the systems record everything or anything that passes between the points where the system is.

However, this technology has disadvantages, as well. These occur because the signals must align exactly with one another to have effective communication. Their range is very small. Objects and weather can block a transmission. Data passes from device to device much slower than with other wireless transmissions.

This technology continues to grow in the areas of ATMs, information booths, building directories, TV set top boxes, bus stops, ticket machines, touch screens, point of sale equipment, heating and cooling controls in a household, home security systems, whiteboards in schools and offices, as well as games and entertainment.

Once implemented, all these services will make life easier for the disabled. They will have access to things that currently they cannot access without of help of another person. The technology seeks to provide a special IR device to disabled persons so they can get around transportation areas by themselves without the aid of another human. Eventually, the technology will not interfere with other electronic devices. This device will automatically recognize that the person has a disability and help without accessing another system. Interested people may access additional information about this specialized technology through the email [email protected]. This technology works especially well for blind persons or persons with spinal disabilities.

Photographers use infrared rays to see areas otherwise not seen by visible light. Astronomers, too, use this technology to illuminate "dark" or cloudy skies. The rays allow persons 'to see in the dark.' With infrared, dusty areas of the sky once thought invisible by astronomers have many stars and stellar matter.
