Abstract

The invention concerns pen-based computers, wherein a pen, or stylus, is positioned on a display of the computer, and produces a signal which allows the computer to detect the position of the stylus. The stylus produces a second signal, which is used as a carrier for telemetry, to transmit data from the stylus to the computer.
