Abstract

A system for providing an electrical interface across a sealed boundary may include a frame in sealed engagement with at least a portion of a substrate. The substrate may be in communication with an electrochromic device. The system may further include first and second conduits. The first conduit may be on a first side of the substrate and a second conduit may be on a second side of the substrate. The second conduit may be in communication with the first conduit through at least one of the seal, a space between the seal and the frame, and a space between the seal and the substrate.

Claims

1. A system for providing an electrical interface across a sealed boundary comprising:

a frame in sealed engagement with at least a portion of a substrate via a seal, the substrate being in communication with an electrochromic device; and

first and second conduits, wherein the first conduit is on a first side of the substrate and a second conduit is on a second side of the substrate, wherein the second conduit is in communication with the first conduit through at least one of (i) the seal, (ii) a space between the seal and the frame, and (iii) a space between the seal and the substrate.

2. The system of claim 1, wherein the first and second conduits are ends of a connectivity harness.

3. The system of claim 1, further comprising at least one conduit cable, wherein at least one of the first and second conduits form at least an end portion of the at least one conduit cable.

4. The system of claim 3, wherein the at least one conduit cable is in sealed engagement with the seal.

5. The system of claim 4, the substrate having a recess at a portion of the perimeter of the substrate adapted for engagement with the at least one conduit cable, wherein the at least one conduit cable is in sealed engagement with the one of the first and second seals at the substrate recess.

6. The system of claim 3, wherein the conduit cable passes through one of (i) the seal, (ii) the space between the seal and the frame, and (iii) the space between the seal and the substrate.

7. The system of claim 3, wherein the at least one conduit cable is a flexible ribbon cable.

8. The system of claim 7, wherein the flexible ribbon cable has a thickness ranging from about 0.035 to about 0.040 inches across a width thereof.

9. The system of claim 3, wherein the at least one conduit cable is a flexible printed circuit.

10. The system the claim 9, wherein the flexible printed circuit is substantially flat having a consistent thickness ranging from about 0.008 to about 0.015 inches across a width thereof.

11. The system of claim 3, wherein the at least one conduit cable is formed of multiple layers.

12. The system of claim 11, wherein the at least one conduit cable comprises a stepped edge.

13. The system of claim 3, wherein the at least one conduit cable has a tapered edge on an end thereof.

14. The system of claim 13, wherein the tapered edge comprises a tip at an extremity of the edge, wherein the tip of the tapered edge is in sealed engagement with the substrate.

15. The system of claim 1, wherein the first and second conduits are connected through a connectivity module.

16. The system of claim 15, wherein the connectivity module is connected to the electrochromic device through a cable connection.

17. The system of claim 15, wherein the connectivity module is connected to the electrochromic device through a connector socket extending from the connectivity module.

18. A system for providing an electrical interface across a sealed boundary comprising:

a frame in sealed engagement along at least a portion of a substrate, the substrate being in communication with an electrochromic device; and

first and second conduits, wherein the first conduit is on a first side of the substrate and a second conduit is on the second side of the substrate, wherein the second conduit is in communication with the first conduit through a hole in the substrate.

19. A system for providing an electrical interface across a sealed boundary comprising:

a frame in sealed engagement along at least a portion of first and second plates separated by a space, each of the plates being in communication with an electrochromic device; and

first and second conduits, the first conduit being an electrical conductor applied to the first plate and the second conduit being an electrical conductor applied to the second plate,

wherein the second conduit is in communication with the first conduit across the space.

20. The system of claim 19, wherein the first and second conduits are conductive bus bars wrapped around an edge of the respective first and second plates so as to have ends on opposing sides of the plates.

21. The system of claim 19, wherein at least one electrical connector for attachment and electrical connection with at least one mating electrical connector extends from at least one of the first and second conduits on a side of the respective plate opposite the space.

22. A system for providing an electrical interface with moveable barriers comprising:

a frame;

a moveable barrier in mating engagement with the frame, wherein the moveable barrier is one of (i) a sliding window and (ii) an articulating window;

a first communication module attached to the frame; and

a second communication module attached to the movable barrier,

wherein the second communication module is in wireless communication with the first communication module, and a wireless signal is used to confirm that the sliding or articulated window is one of open and closed.
