...Signal? Schevill has been fascinated by whale talk since he worked with the Navy during World War II. During his work he made tapes of underwater sounds, later tried them out on an ancient mariner from the whaling port of New Bedford. One sound always got an instantaneous response from the ex-whaler: "That's a sperm snappin' his spouter...
...Dunning had good reason to be excited. Last week Columbia scientists and the Air Force's Air Research and Development Command jointly called in the press to announce a fundamentally new technique of multiplying the effectiveness of radar by "many hundreds of times" through a radical system of signal identification...
...amplify the returning echo of the electromagnetic wave after it bounces off the target, without simultaneously amplifying the random electrical interference that is also picked up by the receiver. Heretofore, the usual method of improving reception has been the brute-force approach of multiplying the power of the signal. But this multiplication requires costly and cumbersome equipment, is impractical for such isolated sites as the arctic...
Columbia scientists, working on an Air Force contract, dodged around this difficulty by altering the quality of the signal itself. Details of the alteration are still secret. But in effect the scientists added an ingredient to the signal that can be readily identified against background interference picked up by their receiver. "It's a lock and key system," explains Dr. John H. Bose of Columbia's Electronics Research Laboratories. "We know what's locked up in the signal, and our receiver...
Mayor Dilworth even kept an eye peeled for traffic problems, reported pointedly from London that drivers move and stop "promptly on signal, automobiles stay in their proper lanes, and you see no weaving or cutting in or out." Concluded His Honor: "It is just another example of what decent observance of the law, and of regard for one another, can accomplish...
