    Abstract: A garage door assembly including a door for enclosing an opening, and a mechanism for selectively deploying the door in a closed position to cover the opening, and an open position with the door stored leaving the opening open. A position reading assembly monitors a position of the door with respect to the opening. The position reading assembly includes a controller and three switches in communication with the controller. The switches are positioned such that movement of the door actuates the three switches and, in turn, the controller divides the door into eight virtual zones between the closed and open positions.
