Abstract

L'invention concerne un téléphone à pièces de monnaie. Un microprocesseur calcule un temps final T dont l'usager dispose, et un temps résiduel T - A au bout duquel est émis le signal de paiement complémentaire. Le temps final T est donné par T= RG/TW.t où RG est l'avoir résiduel, TW la valeur d'impulsion de taxe et t la période d'impulsion de taxe. Le temps résiduel T - A produit son effet lorsque le temps final T est inférieur ou égal à 2A (T <= 2A). Le calcul du temps final T et la détermination du temps résiduel T - A ont lieu à l'arrivée de chaque impulsion de taxe. Application notamment aux téléphones publics automatiques.
