Abstract

An x-y digitising system is described which operates with a resonant stylus. The x-y digitising system includes an excitation winding for energising the resonant stylus and a number of sensor windings for receiving a signal re-radiated by the resonant stylus when energised. At least one of the excitation winding and the sensor winding is arranged to have its effective magnetic axis non-othogonal to the working area of the x-y digitising system. With this arrangement, improved energy transfer between the x-y digitising system and the resonant stylus can be achieved and/or improved position measurement accuracy can be obtained.
