Abstract

A system for pointing a device at a given target has a sensor for sensing a number of positional information points of the target with the sensor relaying the positional information points to a controller. The controller is for computing a directional control information based on the relayed positional information points. The system also has an adjustment device for moving the device in a direction that bears a predetermined relationship to the target in response to the computed direction control information. The target moves and the sensor senses the positional information of the target and the sensor relays the positional information to the controller with the controller computing the directional control information to control the adjustment device. The adjustment device points the device at the target.
