Honeywell's researchers have developed infra-red sensing tubes that can detect a frying pan's heat from five miles away - or spy out a distant rocket - and a humidity register so sensitive that it knows when a teaspoonful of water is brought into a room. It took a Honeywell gyroscope to measure the Empire State Building's maximum sway (onequarter inch) and bury forever the tourist canard that the world's tallest building rocks in a high wind. Eye examinations will eventually be more comfortable because of a Honeywell device that measures eyeball pressure with...
Danger of eye-burn from infra-red radiation cannot be over-emphasized, however. Smoked or dark glasses are inadequate protection for the eyes, and use of them often leads to serious eye damage...
...West have benefited enormously from far more modern devices. It is now possible to eavesdrop on a conversation held in the middle of an empty prairie by simply pointing a beam of light from 500 yards away. New cameras can take pictures in total darkness without the use of infra-red light. Finely ground lenses can zoom in from blocks away to pick up the fine print on an insurance policy. But the Soviets like the more old-fashioned and romantic gadgets, mostly, it seems, from a native passion for melodrama...
...look directly at the eclipse." What makes an eclipse so dangerous is that it works insidiously. As the twilight deepens, the viewer can look at the sun without squinting. Meanwhile, the pupils of his eyes are opening wider -just in time to receive the shattering bombardment of infra-red rays that continue after most of the visible radiation is gone. There is no warning pain as the radiation passes through the viewer's dilated pupil and is focused onto the center of the retina, even when the concentrated rays burn a hole in this sensitive, irreplaceable screen. Slight damage...
...president of Barnes Engineering Corp., which developed the camera, describes the picture taken on photographic film as a "thermal map of the skin." The instrument does not ir radiate the subject in any way. Instead, it scans the body surface for six to twelve minutes to register the invisible infra-red rays emitted by the body itself. Where blood concentrates close to the surface-in veins, infections or abnormally rapid growths-the skin runs a higher temperature and the thermogram shows a light spot. Where there are areas of low metabolism-such as hair and scars or inactive growths close...
