The most celebrated invention of frequency hopping was that of actress Hedy Lamarr and composer George Antheil, who in 1942 received patent number 2,292,387 for their “Secret Communications System.” This early version of frequency hopping used a piano-roll to change between 88 frequencies, and was intended to make radio-guided torpedoes harder for enemies to detect or to jam. The patent was rediscovered in the 1950s during patent searches when private companies independently developed Code Division Multiple Access, a civilian form of spread-spectrum.<\/p><\/blockquote>\n
Can you believe it? \u00c2\u00a0Hedy Lemarr helped to invent a practical wide sprectrum, frequency hopping radio communications system…. \u00c2\u00a0Where did I find this? \u00c2\u00a0Not Wikipedia… \u00c2\u00a0Nope, right here…<\/a>at Britney Spears’ Guide to Semiconductor Physics.<\/a><\/p>\n
Yes, I was taking a look at the sight, after seeing references to it on a slashdot article. I assumed it was a spoof site, but it looks accurate, and educational.<\/p>\n
