Even more amazing is her patent was not implemented until transistors were used in the 1950's, she was ahead of her time.
Frequency hopping proved even more useful in radar design.
It's HEDLEY!
Her full name was Hedwig Eva Maria Kiesler - Her stage-name was always Hedy Lamar. If you have proof, please share it. (I could be wrong myself.) 🙂
Thank you Mrs. Lamarr !
Brilliant...How does the receiver in the torpedo follow each freq shift from the transmitter?
They are sender and receiver are set to send and receive signals by a synchronized clock.
She partnered with a Composer named George Antheil. Antheil composed a song to be played by 100 player pianos at the same time. The paper rolls to control the pianos were identical and started at the same time. They made a prototype for the frequency hopping device using miniature player piano mechanisms. Think of a little music box mechanism that turns a little spindle with bumps on it making the tune. Come to think of it, not unlike the early IBM cards with the holes punched out. Just start the transmitter in the ship and the receiver in the torpedo at the same time.
@@podunkcitizen2562 Hedy's father engaged her childhood curiosity in regards explaining how basic everyday technology of the day worked. Likewise, as a young child, she took apart her music box which can be considered a 'frequency hopping device', dating back to ~1770. So the concept of 'shifting/hopping frequencies' was nothing new. Likewise, it's typical of most 'inventors' mindsets, to see the related qualitative associations and interconnections that give rise to related inspirations - its how our minds work via pattern recognition and related inferences. In Hedy's case, she didn't need an technical degree to put two and two together, where she'd picked up on 'frequency jamming' during her first marriage. So, perhaps the music box was what really inspired her notion of 'frequency hopping', also working in a fixed, synchronous fashion. p.s. The concept of frequency shifting controlled via perforated media was a well established communications patent from decades earlier. It's more so where using a 'player piano' style mechanism would be the unique basis for the patent by Hedy & Company. Solely as a alternative mechanism, a variation of the earlier patents which Hedy & Co. would not have known about.
Yep she was highly intelligent just like my father
Her Expired patent stopped her from getting noticed and rewarded..lol Wow !! Shame on the U.S Navy
Hedwig Eva Maria Kiesler.
That’s Hedley.
Full name was Hedwig Eva Maria Kiesler - Stage name was always Hedy Lamar - If you have proof please share it?
Answer me this simple question: were the PhD's and scholars is in wireless communication at that time were so dumb that they did not come up with this idea that an actress out of nowhere invented.
Because it's a mindset. She kept inventing stuff. Getting a PhD involves persistence more than anything else: you simply stay in school long enough, and many inventors don't have a degree, they are creative minds first and foremost. The fundamentally mistaken assumption in your statement is considering her as "being" an actress. You could argue that it was simply something she did at some point, but your (main) job shouldn't necessarily define who you are.
@@idfx1000 good comment
she wasnt just an actress she has got a mind
hedy invented the wheel....and fire
She stole that idea.
From whom?
And your privy on this fact?
Shut up, you know nothing
Nikola Tesla doesn't mention the phrase “frequency hopping” directly, but certainly alludes to it. Entitled Method of Signaling, the patent describes a system that would enable radio communication without any danger of the signals or messages being disturbed, intercepted, interfered with in any way.
No, she didn't steal it. Nobody had her idea at the time. No records of it in Germany, and they kept records on everything. And she arrived at the idea through a different unique route. The patent office would've found a problem and Lyon and Lyon, her patent attorneys, would've found a problem. Nikola Tesla had another idea years before but it wasn't the same as it did not use multiple frequencies and was much more primitive as radio telegraphy wasn't that advanced yet. She and George Antheil worked on it from 1940 - 1942 with the help of a professor at Cal Tech and the Inventors Council in Washington, D.C. There's much on the history of it since it was declassified.
