| abstract | ABSTRACT OF THE DISCLOSURE An improved optical pointing device utilizing a moveable unit having a voltage-to-frequency converter. The VFC emits pulses with separation proportional to the angular rotative and/or translational position of the moveable unit which pulses are applied to an LED of the moveable unit. A microcomputer in a base unit measures separation of the pulses received by a photodetector to determine the components of the angular rotative and/or translational position of the moveable unit. In accordance with another aspect, automatic gain control circuitry is located in the moveable unit, thereby eliminating the need for two-way communication to achieve consistency of operation in a prescribed space. |
