...about the size of a moving van, crammed with electronic gear, and about a dozen new men to tend its innards. What was it for? Defense Secretary Robert McNamara insisted at first that the equipment "consisted in essence" of normal radio receivers that gave the ship "added capacity" to detect indications of possible attack. In testimony released at week's end, however, he admitted that, far from being routine, the electronic gear was designed to somehow "trigger" North Vietnamese radar so that the U.S. would know the frequencies of Northern radar installations. Then, in an amazing turnabout, the Navy...
...they pass through the ocean depths, submarines invariably give off "scars"?traces of heat and turbulence caused by the ship's passage through the waters. The U.S. employs ultrasensitive infra-red devices in satellites and planes to look down into the oceans and detect the scars. Submarines also give off what Navymen call "an electronic signature" that, like a human fingerprint, is unique. The signature is the sum total of the sub's sounds?the beat of its screw, thump of its pumps, rustle of its wake. To detect those signatures, the U.S. uses a variety of acute listening...
...Russians lag well behind the U.S. in submarine warfare. One reason is that their ships are slower (about 25 knots submerged), make more noise and cannot dive so deeply as U.S. subs, and are thus easier to detect. But the Soviets are continually trying to improve. They are using their big hydrographic fleet to learn more about the sea environment and to find hiding places in the canyons of the ocean for future gen erations of deep-diving submarines. The U.S. Navy tries to keep up with even the most minor changes in the development and deployment of Soviet subs...
Simultaneously time-sharing has started to expand faster than batch-processing. The Medical School, and medicine in general, have started buying large chunks of time on the SDS 940. One new project responsible for this upsurge is a heart-care unit to monitor continuous heart-patient problems, and to detect subtler signs of danger than the cardiologist can ordinarily hope to notice. Consoles also aid interviews with patients suspected of having genetic problems, by rapidly accumulating genetic history...
...tune in a device that can reproduce a three-dimensional image of an enemy submarine scores of fathoms below the surface. Or a brain surgeon may have at his fingertips the means to see, in 3D, a deep, tiny tumor that even modern X-ray techniques could not detect. Such far-out capabilities are now within reach thanks to Scientists Alexander Metherell, John Dreher, Lewis Laramore and Hussein El-Sum, of the McDonnell Douglas Corp.'s Advanced Research Laboratories at Huntington Beach, Calif. Last week, writing in the Journal of the Acoustical Society of America, Metherell and his collaborators...
