Abstract
A motor-operated panel system includes a panel assembly consisting of an elongated flexible web formed of a plurality of different panels connected end-to-end for controlling the transmission of light, heat or air through a window and/or for producing different decorative scenes within a room. The panel assembly is wound on substantially identical elongated and spacedly arranged hollow rollers including an upper roller which contains a reversible motor, gear train, magnetic brake and a position sensor totally within the interior of the upper hollow roller. The position sensor serves to sense the absolute rotational position of the upper roller. The lower roller contains a torsional spring which is prewound to exert a pulling torque on the panel assembly, which torque is normally resisted by the magnetic brake in the upper roller. The panel system is controlled remotely from a panel control which may be wall mounted, communicating with the panel system via a data bus. Several panel systems may be controlled from a single panel control and/or any panel system may be operable from more than one panel control.
