Whether in our (ev) high voltage training courses, consultations on the safety of electrical systems or even the personal sphere of life; we can no longer imagine access to the Internet without W-LAN and mobile networks. It is integrated into our lives. A whole series of inventions and developments was necessary so that we can use many different electrically operated devices accordingly. An important prerequisite for implementation is the use of the so-called frequency hopping spread spectrum (FHSS) method. We owe this to Hedy Lamarr and George Antheil, who introduced it in 1942. Hedy Lamarr ( Hedwig Eva Maria Kiesler) had become known primarily as an actress, hardly anyone knew the inventive spirit of this personality born in 1914. For this invention, Hedy Lamarr (together with Antheil) received the Electronic Frontier Foundation Pioneer Award in 1997. In 2014, the inventor, who died in 2000, was posthumously inducted into the National Inventors Hall of Fame. For International Women’s Day, we have chosen her as an important woman in history to whom we want to draw attention.
So today, when we use multimedia to wirelessly instruct our participants in the basics of measurement technology on high-voltage vehicles using insulation resistance determinations and equipotential bonding measurements in the qualification for specialists for high-voltage systems, we also thank Ms. Lamarr for her contribution to technical development.
