发明名称 Position detecting method and device
摘要 <p>The present invention provides a method and a device for detecting position without producing discrepancy caused by residual induction voltage of a resonant circuit, wherein it includes steps for selecting and scanning one of a multiple loop coil positioned parallel to each other towards a detecting direction to receive an electromagnetic wave (S1), and calculating coordinate values of the indicated position provided by a position indicator based upon at least two detected induction voltages (S3), a direction for selecting and scanning of the loop coils is alternatively changed (S5, 6), and the coordinate values are averaged to eliminate the residual induction voltage effect (S8). <MATH></p>
