Hedy Lamarr, rakousko\u2011narozen\u00e1 here\u010dka zn\u00e1m\u00e1 svou ohromuj\u00edc\u00ed kr\u00e1sou, a George Antheil, americk\u00fd skladatel a vyn\u00e1lezce, vytvo\u0159ili nepravd\u011bpodobn\u00e9 partnerstv\u00ed v roce 1940.

Tajn\u00fd komunika\u010dn\u00ed syst\u00e9m<\/h2>\n\n

Jak se bl\u00ed\u017eila druh\u00e1 sv\u011btov\u00e1 v\u00e1lka, Lamarrina znalost vojensk\u00e9 techniky z prvn\u00edho man\u017eelstv\u00ed ji inspirovala k \u00favaze o zranitelnosti r\u00e1diov\u00fdch komunikac\u00ed v\u016f\u010di ru\u0161en\u00ed. Do\u0161la k z\u00e1v\u011bru, \u017ee rychl\u00fdm p\u0159eskakov\u00e1n\u00edm mezi n\u011bkolika frekvencemi m\u016f\u017ee sign\u00e1l uniknout ru\u0161en\u00ed a z\u016fstat zabezpe\u010den\u00fd. Antheil, se sv\u00fdm z\u00e1zem\u00edm v hr\u00e1\u010dsk\u00fdch pi\u00e1nech, navrhl pou\u017e\u00edt podobn\u00fd mechanismus k synchronizaci frekven\u010dn\u00edho sk\u00e1k\u00e1n\u00ed mezi vys\u00edla\u010dem a p\u0159ij\u00edma\u010dem.<\/p>\n\n

Patent na frekven\u010dn\u00ed sk\u00e1k\u00e1n\u00ed<\/h2>\n\n

V roce 1941 podali Lamarr a Antheil patentovou p\u0159ihl\u00e1\u0161ku na sv\u016fj \u201eTajn\u00fd komunika\u010dn\u00ed syst\u00e9m\u201c. Patent popisoval za\u0159\u00edzen\u00ed, kter\u00e9 by pomoc\u00ed dvou motorov\u00fdch v\u00e1le\u010dk\u016f synchronizovalo 88 frekvenc\u00ed, odpov\u00eddaj\u00edc\u00edch po\u010dtu kl\u00e1ves na pianu. N\u00e1mo\u0159nictvo v\u0161ak jejich n\u00e1pad zpo\u010d\u00e1tku odm\u00edtlo jako nepraktick\u00fd.<\/p>\n\n

Zrozen\u00ed rozpt\u00fdlen\u00e9ho spektra<\/h2>\n\n

Navzdory neochot\u011b n\u00e1mo\u0159nictva se koncept frekven\u010dn\u00edho sk\u00e1k\u00e1n\u00ed stal kl\u00ed\u010dov\u00fdm b\u011bhem kub\u00e1nsk\u00e9 raketov\u00e9 krize. In\u017een\u00fd\u0159i ve spole\u010dnosti Sylvania Electronics Systems experimentovali s principy uveden\u00fdmi v patentu Lamarr a Antheila a vyvinuli elektronick\u00e9 prost\u0159edky pro technologii rozpt\u00fdlen\u00e9ho spektra. Tato technologie umo\u017enila bezpe\u010dnou komunikaci i p\u0159i ru\u0161en\u00ed.<\/p>\n\n
