Abstract

L'INVENTION CONCERNE UN CIRCUIT SELECTEUR DE SIGNAUX DE RADIOFREQUENCE. LE CIRCUIT COMPREND UN MOYEN DE MEMORISATION 30, 31, 33, 36 PERMETTANT DE MEMORISER DES INFORMATIONS RELATIVES A L'ACCORD D'UN CERTAIN NOMBRE DE SIGNAUX PREFERES ET UN MOYEN 32 PERMETTANT D'APPELER LADITE INFORMATION; IL COMPREND EGALEMENT UN MOYEN 34, 35, 37 PERMETTANT DE MEMORISER L'INFORMATION RELATIVE A LA POSITION ANGULAIRE OPTIMALE D'UN DISPOSITIF CAPTANT LES SIGNAUX DE RADIOFREQUENCE ASSOCIE AU RECEPTEUR DANS LEQUEL LE CIRCUIT DE L'INVENTION EST PLACE, AINSI QU'UN MOYEN 39, 40, 44 PERMETTANT D'OBTENIR AUTOMATIQUEMENT LA POSITION ANGULAIRE LORS DE L'APPEL DU SIGNAL PREFERE. LES MOYENS DE MEMORISATION SONT ESSENTIELLEMENT REPRESENTES PAR LES CELLULES DE MEMOIRES ELECTRONIQUES 36 ET 37 DU TYPE A SEMI-CONDUCTEURS. L'INVENTION ELIMINE L'EMPLOI DES DISPOSITIFS DE MEMORISATION MECANIQUES ET, PAR CONSEQUENT, LES RISQUES DE DEFAILLANCE ASSOCIES A LEUR UTILISATION.THE INVENTION RELATES TO A RADIOFREQUENCY SIGNAL SELECTOR CIRCUIT. THE CIRCUIT INCLUDES A MEANS OF MEMORIZATION 30, 31, 33, 36 ALLOWING TO STORE INFORMATION RELATING TO THE AGREEMENT OF A CERTAIN NUMBER OF PREFERRED SIGNALS AND A MEANS 32 ALLOWING TO CALL THE SAID INFORMATION; IT ALSO INCLUDES A MEANS 34, 35, 37 ALLOWING TO STORE THE INFORMATION RELATING TO THE OPTIMAL ANGULAR POSITION OF A DEVICE CAPTURING THE RADIOFREQUENCY SIGNALS ASSOCIATED WITH THE RECEIVER IN WHICH THE CIRCUIT OF THE INVENTION IS PLACED, AS WELL AS A MEANS 39, 40, 44 ALLOWING TO AUTOMATICALLY OBTAIN THE ANGULAR POSITION WHEN THE PREFERRED SIGNAL IS CALLED. THE MEANS OF STORAGE ARE ESSENTIALLY REPRESENTED BY ELECTRONIC MEMORY CELLS 36 AND 37 OF THE SEMICONDUCTOR TYPE. THE INVENTION ELIMINATES THE USE OF MECHANICAL STORING DEVICES AND, THEREFORE, THE RISKS OF FAILURE ASSOCIATED WITH THEIR USE.
