Abstract

L'INVENTION CONCERNE UN DISPOSITIF POUR MESURER UNE QUANTITE DE MOUVEMENT D'UN OBJET MOBILE. LE DISPOSITIF EST CARACTERISE EN CE QU'IL COMPREND UN DETECTEUR CONSTITUE PAR L'OBJET MOBILE ET PAR DEUX ELEMENTS FIXES PLACES EN REGARD DE L'OBJET MOBILE DE FACON A FORMER AU MOINS DEUX CONDENSATEURS DIFFERENTIELS, LES SURFACES CORRESPONDANTES DE L'OBJET MOBILE ET DES ELEMENTS FIXES PORTANT DES GRADUATIONS DE MEME PAS, LESDITS CONDENSATEURS COOPERANT AVEC DEUX OSCILLATEURS ET UN MELANGEUR POUR PRODUIRE UN SIGNAL DONT LA FREQUENCE EST ALTERNATIVEMENT AUGMENTEE ET DIMINUEE A CHAQUE FOIS QUE L'OBJET MOBILE SE DEPLACE D'UNE DISTANCE PREDETERMINEE PAR RAPPORT AUX ELEMENTS FIXES. APPLICATION A LA MESURE DE MOUVEMENTS.THE INVENTION RELATES TO A DEVICE FOR MEASURING A QUANTITY OF MOVEMENT OF A MOBILE OBJECT. THE DEVICE IS CHARACTERIZED IN THAT IT INCLUDES A DETECTOR CONSTITUTED BY THE MOBILE OBJECT AND BY TWO FIXED ELEMENTS PLACED FACING THE MOBILE OBJECT SO AS TO FORM AT LEAST TWO DIFFERENTIAL CAPACITORS, THE CORRESPONDING SURFACES OF THE MOBILE OBJECT FIXED ELEMENTS BEARING THE SAME STEADS, THE SAID CAPACITORS COOPERATING WITH TWO OSCILLATORS AND A MIXER TO PRODUCE A SIGNAL THE FREQUENCY OF WHICH IS ALTERNATIVELY INCREASED AND DECREASED EACH TIME THE MOBILE OBJECT MOVES IN RELATION TO THE ELEMENT OF A DISTANCE FIXED. APPLICATION TO THE MEASUREMENT OF MOVEMENTS.
