Abstract: A digital computer based power control system for automatically aligning a first, moveable object with a second, fixed object to aid a human operator in effecting contact or engagement of the first object with the second object in a precise manner. A camera and light assembly on the first object form images of the second object as the first object is automatically positioned. These images are stored in digital form and compared to an ideal image which indicated proper alignment of the first and second objects. This condition is indicated to the human operator to allow movement of the first object to the point of proper alignment. The system includes a main processor, a ROM for storage of control programs, RAM for storage of images, a camera and light assembly, operator controls, and power electronics.
