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.

Claims

1. A panel system comprising:

an elongated panel assembly including a plurality of panels following one another along the length of said panel assembly, said panels being configured to provide various aesthetic, light transmitting, or environment controlling characteristics;

first and second spaced rollers, said panel assembly having first and second ends respectively secured to said first and second rollers and means for selectively winding said panel assembly onto one or the other of said rollers so that any of said panels or portion thereof could be positioned between said rollers;

user actuatable means including plural input means, each of said panels having a corresponding one of said input means; and

control means for automatically positioning any one of said panels that has been selected randomly via said input means between said rollers.

2. The system of claim 1, including panel programming means for said input means and for said control means, said programming means establishing a correspondence between each of said input means and a respective portion of said panel assembly.

3. The system of claim 2, said input means comprising push buttons for operating said programming means to establish said correspondence.

4. A panel system for use in front of a light source comprising:

an elongated panel assembly including a plurality of panels having different characteristics following one another, said panels being selected from a group of panels having unique aesthetic and light transmitting and environment controlling characteristics;

first and second spaced rollers, said panel assembly having first and second ends respectively secured to said first and second rollers and means for winding said panel assembly onto one or the other of said rollers to position any of said panels or portion thereof between said rollers, and in front of said light source;

means for specifying one of plural desired light levels; and

means for selecting and positioning between said rollers a panel suited for establishing a light level corresponding to said one specified light level.

5. A panel system arrangement, comprising:

at least a first and a second panel system, and at least one panel control for controlling said first and second panel systems;

each said panel system comprising;

a) an elongated panel assembly including a plurality of panels following one another along the length of said panel assembly, said panels being configured to provide various aesthetic, light transmitting, or environment controlling characteristics; and

b) first and second spaced rollers, said panel assembly having first and second ends respectively secured to said first and second rollers and being selectively windable onto one or the other of said rollers;

said at least one panel control including user actuatable means for generating commands directing positioning of said panel assemblies between said rollers, each of said panel systems and each of said panel controls comprising a unique device address;

a digital data bus interconnecting said first panel system, said second panel system and said panel control; and

a respective communication means in each said panel system and said panel control for enabling said panel systems and said panel control to communicate digitally with one another via said data bus and based on said device addresses.

6. The panel system arrangement of claim 5, including a respective device address labeling means for each said panel system and for each said panel control, for transmitting trial device addresses, for verifying whether any transmitted trial device address has been previously assigned to another device, and for labeling itself with an available unused address as said unique device address.

7. The panel system arrangement of claim 6, wherein said at least one panel control comprises at least a first and a second panel controls.

8. The panel system arrangement of claim 5, said data bus comprising an idle line state effective for indicating the availability of said data bus for data transmission, each said panel system and panel control including a respective means for initiating data transmission over said data bus after a delay time unique to each said panel system and panel control.

9. The panel system arrangement of claim 8, wherein said delay time equals a time period which is dependent upon said unique device address.

10. The panel system arrangement of claim 7, each said panel system comprising a respective panel system switch, said panel system switch establishing a control relationship between its respective panel system and at least one of said panel controls.
