Abstract:
At least two coils located at different positions with regard to a positioning area are controlled to indicate a position of an object located within the range of magnetic fields generated by the coils. An embodiment of the invention comprises a generator that uses a multiplexing technique to generate coil enable signals for the at least two coils. The coil enable signals are generated for the at least two coils with any of different polarities and different intensities.
