todaysdocument:Hedy Lamarr’s Secret Communication System, 8/11/1942Patent Case File 2,292,387; Patent Case Files, 1836-1993; Records of the Patent and Trademark Office, Record Group 241; National Archives Did you know the screen legend Hedy Lamarr was also a patent holder? Having fled Europe and an unhappy marriage to an Austrian munitions manufacturer, Lamarr relocated to the United States prior to the outbreak of World War II. In collaboration with avant-garde composer George Antheil, the two used knowledge from their respective fields to patent a “secret communication system.” Their invention was intended to guide a torpedo by remote control to an enemy target, utilizing a novel synchronized frequency-hopping radio signal to prevent any jamming or interference from the enemy.Figure 7 above depicts the torpedo in action, controlled from a mother ship and spotter aircraft, adjusting course to account for the ocean current and the enemy ship’s evasive maneuvers.Their innovative system was never adopted during the war, and neither would ever profit from their patent, but their ideas in frequency shifting would later prove instrumental in modern cellular and WiFi communications methods. Both Lamarr and Antheil were later inducted into the National Inventors Hall of Fame in 2014. -- source link
