...years before World War II, Myrbeck worked at Harvard as a research associate in physics and communications engineering helping with the development of sonar and sonic submarine torpedoes...
...moment, ALVINN can go only where he has gone before. The technology-- cameras, laser range finders, sonar and motors--works in three stages. First ALVINN ``sees'' the road by taping it as well as sending out laser and sonar waves as Jochem drives. Then the computer goes into training, replaying the tape thousands of times, studying the details--road signs, lane markers, speed limits. Finally ALVINN drives a stretch of road, handling his own acceleration, braking and steering...
...primary difference in the two types of boats is in the weight. While a lark weighs approximately 200 pounds, sonar weighs in at 4000 pounds...
...fishing industry began sailing into its predicament during the 1970s, when increasingly sophisticated technology enabled fleets of all sizes and nationalities to venture farther from port than ever before. Sonar and radar helped locate the fish wherever they were hiding. Satellite-navigation systems let ships return over and over to prime spots. Newly built "factory ships" deployed nets so huge that they could swallow 12 jumbo jets in a single gulp. Led by the U.S., many countries made waters up to 200 miles from their shores off limits to foreign boats. But as soon as intruding vessels drew farther...
...welded-steel catamaran that is the latest thing in Navy technology: a Stealth ship. Designed by the same Lockheed "skunk works" that built the F-117A Stealth fighter, the ship has sloping angles and a special coating designed to make it nearly invisible to enemy sonar and radar. Such stealthy boats might someday guard the perimeter of carrier groups, covertly launch surface-to-air missiles or make nighttime troop landings all but undetectable...
