## AI overview

The article describes Hedy Lamarr's life as an actress and inventor, focusing on her World War II idea of rapidly changing radio frequencies to help protect torpedo guidance from jamming. It explains that the US Navy did not use the technology and later connects the frequency-hopping concept to Ericsson's work on a data-exchange protocol, while acknowledging uncertainty about whether Lamarr directly inspired it.
