Timeline of United States inventions (1946–91) of the United States Geological Survey. 1960 Gas laser A gas laser is a laser in which an electric current is discharged through a gas to produce light. The first gas laser, the Helium-neon, was invented by William R. Bennett, Don Herriott, and Ali Javan in 1960. The first continuous visible gas laser, operating at 632.8 nm in the red, was invented by A. D. White and J. D. Rigden in 1962. 1961 Spreadsheet (electronic) 1961 Wearable computer 1961 Frozen carbonated beverage 1961 Biofeedback 1962 Communications satellite 1962 Chimney starter 1962 Light-emitting diode A light-emitting-diode (LED) is a semiconductor diode
LED Incapacitator LED Incapacitator The Light Emitting Diode (LED) Incapacitator is a weapon designed like a flashlight. It emits an extremely bright, rapid, and well-focused series of 'differently-colored random pulses.' Before the human eyes can focus in on one frequency, another frequency comes on, causing intracranial pressure, which results in headaches, nausea, vomiting, disorientation, irritability, and visual impairment to the target (opponent). The non-lethal weapon is intended as a means of protection by law enforcement officials such as police and border patrols. The light emitted is capable of rendering opponents temporarily blind so that they can be subdued more easily. According to
