  • Patent number: 4827195
    Abstract: A low-cost system for allowing manual or automatic aiming of a plurality of motor-driven devices distributed throughout an area from a common control center location. When in a manual mode, the operator may manipulate a four quadrant touch pad or a joy stick device to develop binary control signals indicative of rotational direction and the on/off state of a motor control chip associated with each of the motors. The control signals are distributed over a master bus and optionally over additional local buses to the appropriate motor control chips. In an automatic mode, the same control signals are generated to produce repetitive sweeping of the motor-driven devices through a predetermined arc.
