Method and apparatus for the wireless capture of coordinate-shift information

摘要: An apparatus is provided for the wireless capture of coordinate-shift information. The includes a pulse generator that generates signal and simultaneously distributes into first along path second path. further working area defined by plurality crossing X-axis lines Y-axis lines, at least one coil surrounding generating magnetic field. also scanning circuit coupled to area, synchronic determination receiving signals, determining time delay between receipt signals. processing circuit. passes through circuit, contains coordinate shift position indicator can include resonance receives signals from field, then re-transmits having different widths area.
