Abstract

A system and method for controlling power distribution from a plurality of inductive power outlets to a plurality of inductive power receivers include inductive outlets and receivers that are provided with a signal transfer system for communicating unique identification labels. Applications are described relating to the control of modular visual displays and interchangeably situated electrical devices.

Claims

1. A remotely controlled modular display comprising:

a plurality of display panels, each said display panel having a visual output displaying a section of a visual presentation; and

a display master for receiving display data from a remote display engine and for controlling the visual output of said display panels;

wherein said display engine is controlled by at least one computer terminal comprising a storage medium storing computer readable code operable to provide a user interface for controlling said visual output.

2. The remotely controlled modular display of claim 1 wherein said user interface comprises a visual representation of said display panels.

3. The remotely controlled modular display of claim 1 wherein said user interface comprises means for selecting an image to be displayed upon said display panels.

4. The remotely controlled modular display of claim 3 wherein said display engine is operable to adjust display parameters of said image.

5. The remotely controlled modular display of claim 4 wherein said display parameters are selected from the group consisting of:

size, resolution and file type.

6. The remotely controlled modular display of claim 1 wherein said display modules are mountable to a support structure.

7. The remotely controlled modular display of claim 1 wherein said display module comprises a power receiver wired to a display driver, operable to provide a driving signal for adjusting said visual output.

8. The remotely controlled modular display of claim 7 wherein said power receiver comprises an inductive power receiver for inductively coupling with an inductive power outlet wired to a power supply.

9. The remotely controlled modular display of claim 1 wherein at least one said display panel comprises:

at least one inductive power receiver comprising a secondary inductor for inductively coupling with a primary inductor of an inductive power outlet connected to a power source; and

at least one adjustable visual display, electrically connected to said secondary inductor via at least one display driver, wherein the display driver provides a display signal for changing appearance of said visual panel.

10. The remotely controlled modular display of claim 9 wherein at least one said display panel comprises a transmission-guard for preventing said primary inductor from transmitting power in the absence of said adjustable panel.]

11. The remotely controlled modular display of claim 9 wherein said inductive power receiver and said visual display are contained within a sealed casing.

12. The remotely controlled modular display of claim 9 wherein the appearance of said visual display is maintained after said primary inductor stops transmitting power.

13. The remotely controlled modular display of claim 12 wherein:

said visual display comprises an array of pixels, each of said pixels comprise at least one optical element having at least two optical states, said optical element being in conductive contact with at least two electrodes, and said display signal comprises a voltage applied to at least one pair of said electrodes thereby altering said optical element from a first optical state to a second optical state.

14. The remotely controlled modular display of claim 9 wherein said display driver further comprises a signal detector for detecting a control signal from a remote controller.

15. The remotely controlled modular display of claim 1 wherein at least one said display panel comprises a positioning system for communicating coordinates of said panel to said display driver.

16. The remotely controlled modular display of claim 1 wherein at least one said display panel comprises an attachment means for attaching to a surface.]

17. A method for remotely controlling a modular display comprising the steps of:

providing a plurality of display panels, each said display panel having a visual output displaying a section of a visual presentation;

connecting each said display panel to a common display master;

providing a user interface for controlling a display engine to control said visual output;

said display master receiving display data from said display engine; and

said display master controlling the visual output of said display panels in response to said display data.

18. The method of claim 17 wherein at least one said display panel comprises an adjustable visual display electrically connected to at least one display driver and the step of said display master controlling the visual output of said display panels in response to said display data comprises providing a display signal to said adjustable visual display associated.

19. The method of claim 18 wherein said visual display comprises an array of pixels, said pixels comprise at least one optical element having at least two optical states, said optical element being in conductive contact with at least two electrodes, wherein the step of providing a display signal to said visual display comprises said display driver applying a voltage to at least one pair of said electrodes thereby altering said optical element from a first optical state to a second optical state

20. The method of claim 17 wherein said digital master comprises at least one inductive power outlet comprising at least one primary inductor;

and said display panel comprises at least one secondary inductor for inductively coupling with said primary inductor.
