Actress Hedi Lamarr more than just another pretty face. She and musician George Antheil made their contribution to the World War II effort by developing an electronic communications system that effectively manipulated radio frequencies into code.
While this might sound like mumbo jumbo, their invention helped torpedoes hit their targets by preventing their signals from getting jammed by the enemy.
The system is based on frequency hopping. Here's how it works:
Heddy Lamar was a smart screen queen.
Instead of transmitting a signal on one frequency, the spectrum system switches quickly from one frequency to the next, Making it almost impossible to pick it up.
The cordless phone in your home uses a digital version of the spectrum system. Unfortunately for Lamarr and Antheil, the patent expired before they made any real money, but their invention was recognized with an Electronic Frontier Foundation's Pioneer Award.
