Abstract

Portable apparatus for identifying and mitigating defects in electronic devices disposed on substrates or windows wherein such defects can be visually perceived by the end user and wherein the substrates or windows may include flat panel displays, photovoltaic windows, electrochromic devices, and the like, particularly electrochromic windows.

First claim

What is claimed is:

1. An apparatus for mitigating a defect in an electronic device on an electrochromic window having a viewable area, the apparatus comprising:
a first mechanism configured to detect the defect, wherein the first mechanism comprises at least one of a microscope, a camera, and a photo detector;
a second mechanism configured to mitigate the defect, wherein the second mechanism comprises at least one of a laser, a heat source, an induction coil, a microwave source, and a voltage source; and
a third mechanism including an X-Y stage mounted within a frame of the electrochromic window during operation of the apparatus, the X-Y stage configured to move the first and second mechanisms to different positions over the entire or substantially entire surface of the viewable area of the electrochromic window installed in a building or vehicle, and the apparatus being a portable apparatus.

2. The apparatus of claim 1 , wherein the electronic device on the window is an electrochromic device.

3. The apparatus of claim 1 , wherein the largest dimension of the apparatus is not substantially larger than the largest dimension of the window.

4. The apparatus of claim 1 , wherein the largest dimension of the apparatus is smaller than the largest dimension of the window, and wherein the apparatus is configured to mount to the window.

5. The apparatus of claim 1 , wherein the largest dimension of the apparatus is not more than about 20% larger than the largest dimension of the window.

6. The apparatus of claim 1 , wherein the largest dimension of the apparatus is not more than about 10% larger than the largest dimension of the window.

7. The apparatus of claim 1 , wherein the largest dimension of the apparatus is the same as or smaller than the largest dimension of the window.

8. The apparatus of claim 1 , wherein the frame is configured to mount to a wall and/or a window frame in which the window is installed.

9. The apparatus of claim 1 , wherein the frame is configured to mount to a wall and/or a window frame in which the window installed using at least one of a suction cup and a pressure-sensitive adhesive.

10. The apparatus of claim 1 , wherein the apparatus is configured to mount to the window using at least one of a suction cup and a pressure-sensitive adhesive.

11. The apparatus of claim 1 , wherein the first mechanism employs at least one of reflection, scattering, and refraction to identify a defect signature.

12. The apparatus of claim 1 further comprising:
a controller including program instructions for conducting a process including:
scanning the window with the first mechanism to detect the defect; and
positioning the second mechanism appropriately to mitigate the defect.

13. The apparatus of claim 12 , wherein the second mechanism includes at least the laser, the program instructions for conducting the process further including guiding the laser to circumscribe damage in the electronic device which is the underlying cause of the defect.

14. The apparatus of claim 1 , wherein the second mechanism includes at least the laser, the apparatus further comprising:
a first reflecting element configured to reflect a first wavelength of electromagnetic radiation emitted from the laser and to reflect a second wavelength of electromagnetic radiation; and
a second reflecting element configured to reflect the first wavelength of electromagnetic radiation and to pass the second wavelength of electromagnetic radiation; and
wherein the first reflecting element is positioned to reflect the first wavelength and the second wavelength of electromagnetic radiation from, or to, a surface of the window, the second reflecting element is positioned to reflect the first wavelength of electromagnetic radiation from the laser to the first reflecting element and to pass the second wavelength of electromagnetic radiation to the first mechanism.

15. The apparatus of claim 14 , wherein the first reflecting element includes a mirror, and wherein the second reflecting element includes a dichroic mirror.

16. The apparatus of claim 14 , further comprising an illumination source configured to produce the second wavelength of electromagnetic radiation.

17. The apparatus of claim 14 , further comprising optics for focusing the first wavelength of electromagnetic radiation onto the window at a position of the defect.

18. The apparatus of claim 14 , further comprising:
a controller including program instructions for conducting a process including:
aligning the apparatus with the defect using the first mechanism;
emitting a low power first wavelength of electromagnetic radiation from the laser that is detected by the first mechanism; and,

aligning the apparatus such that the first wavelength of electromagnetic radiation impinges at a position of the defect, when there is an offset between the alignment of the apparatus using the first mechanism and the detected low power first wavelength of electromagnetic radiation.

19. The apparatus of claim 1 , further comprising an illumination mechanism configured to illuminate the defect in the electronic device on the window and to substantially block energy from the second mechanism with a backstop when the second mechanism is used to mitigate the defect, the illumination mechanism being positioned on a first side of the window, and the first mechanism, the second mechanism, and the third mechanism being positioned on a second side of the window.

20. The apparatus of claim 19 , wherein the illumination mechanism includes at least one of a light emitting diode and a halogen lamp.

21. The apparatus of claim 19 , wherein the second mechanism includes at least the laser, and wherein the illumination mechanism further includes an optical filter configured to block a wavelength of electromagnetic radiation emitted from the laser.

22. The apparatus of claim 19 , further including a communication mechanism configured to enable communication between the second mechanism and the illumination mechanism, the communication mechanism including at least one of optical transceivers and inductive proximity detectors.

23. The apparatus of claim 19 , wherein the second mechanism is configured to be disabled when the communication mechanism indicates that the illumination mechanism and the second mechanism are not in close proximity.

24. The apparatus of claim 1 , wherein the first mechanism includes an illumination source and an optical sensor, the illumination source positioned to illuminate the window at a small glancing angle, wherein a profile of the defect reflects light to the optical sensor.

25. The apparatus of claim 24 , wherein the second mechanism includes a laser and a focusing lens configured to focus a beam from the laser, and wherein the focusing lens is also configured to collect light scattered by the profile of the defect.
