An infrared emitter is an electrode on a transistor from which a flow of electrons or holes enters the region between the electrodes. This device operates at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. LED IR emitters enhance night vision capabilities for military personnel for infrared vehicle lighting, security lighting applications and covert general area IR lighting. Magnalight LED IR emitters can be configured for 850nm IR light, 940nm IR light or a combination of visible and IR LED lighting. Magnalight LED based infrared lighting generates light energy only in the configured wavelength. More traditional covert IR lighting utilizes cut off lenses to block the visible light, while enabling only specific wavelengths to pass through the filter lens. LED infrared lighting is more efficient because all of the light energy from the LEDs is utilized. Finally, with IR LED lighting, there is no possibility of visible light leakage that occur if a cut off lens or related seals are broken.
Life is characterized by energy. All cells produce and maintain an electrical charge across their membranes. Each healthy cell membrane has an electrical charge of 70 milivolts (mv) while diseased cells such as cancer cells have a potential of 15 mv. Nerve impulses are actually small electric currents. Contraction of muscles is caused by the creation of chemical energy. Enzymes, proteins that speed up and facilitate the breakdown of food particles, clearing and repair of injured tissues, and specialized activities within cells, have been described as carriers of energy. The forms of energy we are familiar with include light, heat, sound, and electricity. These types of energy have both particle and wavelike properties, and they can be measured in terms of amplitude and frequency. They are known as transverse waves. Magnetism is an energy field that surrounds a moving electrical current, and can be detected by its effect on conductive metals.
This beautifully designed Massager, shaped as a dolphin, is a superb handheld massager. It is a hand held massager in lightweight and small in size to be convenient for massage in any part of the body. It produces a strong vibration effect which penetrates deep inside the muscles and activates its cells. The Dolphin handheld massager is compact yet amazingly powerful.
