Abstract
A distributed intelligence system for controlling a plurality of groups and equipment for use in dentistry is disclosed wherein the system comprises four separate micro controllers; each micro controller contains its own predetermined routines and a first micro controller being located within control circuitry wherein the control circuitry generates control signals for a first group of tools or equipment, a second micro controller being located within foot switches wherein the foot switches generate control signals for a second group of tools or equipment, a third micro controller located within a control console wherein the control console generates control signals for a third group of tools or equipment and a forth micro controller being located within a power supply wherein the power supply generates control signals for a forth group of tools or equipment. The micro controllers are all interconnected by a wire cable and communicate with one another using a serial communication bus protocol.
