During World War II, when Heidi learned that the German submarine sank the Allied transport ship, she took the initiative to ask the US government to participate in the design of military wireless communication and torpedo remote control system in order to attack the German submarine more accurately.
Heidi was inspired by composer George Ansai's piano playing experience, and soon the two of them created an anti-interference communication device, which can automatically encode and decode.
1942 In August, Heidi and Ansel's "Frequency Hopping Communication Technology" obtained an American patent with the patent number of 2292387, which was named "Secure Communication System". This is an unusual technology, which uses multiple frequencies to communicate, making communication safer and less susceptible to interference and eavesdropping.
This technology is not only used in radio communication systems, but also extended to other fields, such as CDMA, WiFi and Bluetooth.
Character evaluation:
Hedy lamarr is a famous Hollywood movie star, and has a good personal relationship with military leaders of various countries. Heidi used to be the cover of American Inventions and Technological Heritage magazine owned by Forbes, which is probably the most beautiful cover in the magazine's history. Hedy lamarr after Hollywood is still amazing, but her acting career is hard to make progress.
She has been married six times and was jailed twice for shoplifting. More importantly, she was able to put forward the new concepts of "frequency hopping" technology and a series of wireless signal technologies more than 60 years ago, among which "frequency hopping" technology laid the foundation for 3G mobile communication technology which was popular in 2 1 century. This beautiful and intelligent woman changed the world with her own wisdom.
