ABSTRACT:
A computer system has a cordless keyboard having an on-board power supply and a magnetic field generator with the keyboard adapted for coding keystrokes made on the keyboard in a dynamic magnetic field broadcast by the magnetic field generator. There is also an electronic card module having an induction coil for receiving the coded keystrokes in the dynamic magnetic field and having decoding circuitry connected to the induction coil for converting the coded keystrokes in the dynamic magnetic field into standard serial bus data. A computer as part of the system has a docking bay adapted for receiving and engaging the electronic card module and connecting the decoding circuitry in the electronic card module by means of multi-pin connectors to an internal bus of the computer.
