Abstract

L'INVENTION CONCERNE LES DISPOSITIFS D'ALARME ANTI-INTRUSION. UN SYSTEME DE DETECTION D'INTRUSION COMPREND ESSENTIELLEMENT UN DISPOSITIF 16 QUI EST PLACE CONTRE UNE PAROI D'UNE PIECE 10 A PROTEGER, ET QUI PROJETTE UN FAISCEAU ULTRASONORE 20 DANS CETTE PIECE. UN TRANSDUCTEUR DE RECEPTION 30 RECOIT L'ENERGIE ULTRASONORE QUI EST REFLECHIE PAR UNE SURFACE DE REFERENCE 24 QUI EST DEFINIE PAR UN OBJET 25. LE DISPOSITIF DETECTE TOUTE VARIATION DE L'ENERGIE ACOUSTIQUE REFLECHIE QUI RESULTE DE LA PRESENCE D'UN OBJET INTRUS DANS LE FAISCEAU ULTRASONORE. APPLICATION AUX SYSTEMES DE PROTECTION CONTRE LE VOL.
