Abstract

L'invention concerne un système de numérisation x-y fonctionnant au moyen d'un stylet à résonance. Ledit système de numérisation comprenant un bobinage d'excitation destiné à mettre en fonctionnement le stylet à résonance et de nombreux bobinages de capteurs destinés à recevoir un signal ré-émis par le stylet à résonance lorsqu'il est mis en fonctionnement. Au moins un des bobinages d'excitation et un des bobinages de capteur sont disposés de façon à présenter leur axe magnétique efficace non orthogonal à la zone de travail dudit système de numérisation x-y. Un transfert d'énergie amélioré entre le système de numérisation x-y et le stylet à résonance peut être effectué et/ou la précision améliorée de la mesure de la position peut être obtenue à l'aide dudit dispositif.An x-y scanning system is operated using a resonant stylus. Said digitization system comprising an excitation coil intended to activate the resonance stylus and numerous sensor coils intended to receive a signal re-emitted by the resonance stylus when it is put into operation. At least one of the excitation coils and one of the sensor coils are arranged so as to present their effective magnetic axis which is not orthogonal to the working zone of said x-y digitization system. Improved energy transfer between the x-y scanning system and the resonance stylus can be performed and / or the improved accuracy of position measurement can be achieved using the device.
