Hedy Lamarr for the 'secret communication system. It works like this: A signal is broadcast over a seemingly random series of radio frequencies, hopping from frequency to frequency at split-second intervals. The signal could carry spoken words or commands for a torpedo. A receiver, hopping between frequencies in synchrony with the transmitter, picks up the message. Would- be eavesdroppers hear only unintelligible blips. Attempts to jam the signal succeed only at knocking out a few small bits of it. So effective is the concept that it is now the principal antijamming device used in the U.S. government's $25 billion Milstar defense communications satellite system. http://www.freerepublic.com/focus/f-news/556559/posts Jun 18 06, 8:59 AM
