Abstract
A cordless transducer/cursor having a transmitter for use in conjunction with the receiver of a digitizer tablet. The transmitter receives parallel binary signals representing the status of non-positional functions such as command button status and the pressure applied to a stylus of the transducer/cursor and converts these into a serial stream of binary data for electrostatic or electromagnetic transmission to the receiver which, in turn, converts the serial stream into a plurality of parallel binary signals consistent with those received and converted by the transmitter.
