Abstract

A.DISPOSITIF DE COMMUTATION DE SIGNAUX OPTIQUES DU GENRE COMPORTANT UNE PLURALITE DE SOURCES LUMINEUSES UNE PLURALITE DE RECEPTEURS DE LUMIERE ET DES MOYENS POUR AIGUILLER SUR AU MOINS UN RECEPTEUR LE FLUX LUMINEUX D'AU MOINS UNE SOURCE. B.LESDITS MOYENS COMPRENNENT UN EXPLORATEUR OPTO-ELECTRONIQUE CAPABLE DE SCRUTER LES SOURCES UNE A UNE, UN VISUALISATEUR ELECTRO-OPTIQUE CONNECTE EN SORTIE DE L'EXPLORATEUR POUR TRADUIRE EN SIGNAUX LUMINEUX LES SIGNAUX ELECTRIQUES QU'IL EN RECOIT ET CAPABLE D'IMPRESSIONNER LES RECEPTEURS UN PAR UN ET UN DISPOSITIF DE COMMANDE DU TRAJET DE SCRUTATION DE L'EXPLORATEUR ET DU TRAJET D'IMPRESSION DU VISUALISATEUR. C.COMMUTATION TELEPHONIQUE AUTOMATIQUE.A. OPTICAL SIGNAL SWITCHING DEVICE OF THE KIND INCLUDING A PLURALITY OF LIGHT SOURCES A PLURALITY OF LIGHT RECEIVERS AND MEANS FOR DIRECTING THE LIGHT FLOW FROM AT LEAST ONE SOURCE TO AT LEAST ONE RECEIVER. B. THE SAID MEANS INCLUDE AN OPTO-ELECTRONIC EXPLORER CAPABLE OF SCRUING THE SOURCES ONE BY ONE, AN ELECTRO-OPTICAL VISUALIZER CONNECTED TO THE EXPLORER OUTPUT TO TRANSLATE THE ELECTRIC SIGNALS THAT IT RECEIVES INTO LIGHT SIGNALS AND CAPABLE OF PRINTING THE ONE-BY-ONE RECEIVERS AND ONE CONTROL DEVICE FOR THE EXPLORER SCRUTATION PATH AND THE VIEWER PRINT PATH. C. AUTOMATIC TELEPHONE SWITCHING.
