CA 2352363
A low cost x-y digitising system is provided for use in consumer electronic devices, such as portable digital assistants, mobile telephones, web browsers and the like. The digitiser includes a resonant stylus, an excitation winding for energising the resonant stylus and a set of sensor windings for sensing the signal generated by the stylus, from which the x-y position of the stylus is determined.
L'invention concerne un système de numérisation X-Y à faible coût destiné à être utilisé dans des dispositifs électroniques de consommation, tels que des assistants numériques portables, des téléphones mobiles, des explorateurs Web et analogues. Le numériseur comprend un stylet résonnant, un bobinage d'excitation permettant d'exciter le stylet résonnant et un ensemble de bobinages de capteur destiné à capter le signal émis par le stylet, à partir duquel la position X-Y du stylet est déterminée.
