Abstract

A fastener includes a head that is configured to be engaged by a tool, and a shaft extending from the head. The shaft includes a distal end that is opposite from the head. At least one optical component is coupled to one or both of the head or the shaft. The optical component(s) is configured to allow light to pass through the fastener. A window system includes a panel that includes an exterior surface and an interior surface, and the fastener extending between the exterior surface and the interior surface of the panel. A screen is coupled to the interior surface. The screen receives light from the optical component(s) of the fastener.

First claim

The invention claimed is:

1. A window system comprising:
a panel that includes an exterior surface and an interior surface;
a fastener extending between the exterior surface and the interior surface of the panel, wherein the fastener comprises at least one optical component that is configured to allow light to pass through the fastener; and
a screen coupled to the interior surface, wherein the screen receives light from the at least one optical component of the fastener.

2. The window system of claim 1 , wherein the fastener further comprises:
a head that is configured to be engaged by a tool; and
a shaft extending from the head, wherein the shaft includes a distal end that is opposite from the head,
wherein the at least one optical component is coupled to one or both of the head or the shaft, wherein the at least one optical component is configured to allow light to pass through the fastener.

3. The window system of claim 1 , wherein the screen is spaced apart from the fastener.

4. The window system of claim 1 , further comprising an imaging device between the fastener and the screen.

5. The window system of claim 4 , wherein the imaging device comprises a charge coupled device (CCD) array.

6. The window system of claim 1 , wherein the at least one optical component comprises at least one lens.

7. The window system of claim 6 , wherein the at least one lens is proximate to a head of the fastener.

8. The window system of claim 6 , wherein the at least one lens is proximate to a distal end of the fastener.

9. The window system of claim 6 , wherein the at least one lens comprises:
a first lens proximate to a head of the fastener; and
a second lens proximate to a distal end of the fastener.

10. The window system of claim 1 , wherein the at least one optical component comprises a fiber optic member extending along at least a portion of a length of the fastener.

11. The window system of claim 1 , wherein the at least one optical component comprises:
a fiber optic member extending through a central channel of the fastener that extends between a head and a distal end; and
a lens proximate to the head or the distal end, wherein the lens is configured to focus light into a light-receiving end of the fiber optic member.

12. The window system of claim 11 , wherein the fiber optic member is separated from the lens within the central channel by a space.

13. The window system of claim 1 , wherein one or both of a head or a distal end of the fastener comprises an imaging device coupler that is configured to removably couple to a portion of an imaging device.

14. A method of forming a window system, the method comprising:
providing a panel that includes an exterior surface and an interior surface;
providing a fastener with at least one optical component that is configured to allow light to pass through the fastener;
extending the fastener between the exterior surface and the interior surface of the panel;
coupling a screen to the interior surface; and
receiving light at the screen from the at least one optical component of the fastener.

15. The method of claim 14 , further comprising spacing the screen apart from the fastener.

16. The method of claim 14 , further comprising disposing an imaging device between the fastener and the screen.

17. The method of claim 14 , further comprising providing the at least one optical component as at least one lens.

18. The method of claim 14 , further comprising providing the at least one optical component as a fiber optic member extending along at least a portion of a length of the fastener.

19. The method of claim 14 , further comprising providing the at least one optical component as a fiber optic member extending through a central channel of the fastener that extends between a head and a distal end, and a lens proximate to the head or the distal end, wherein the lens is configured to focus light into a light-receiving end of the fiber optic member.

20. An aircraft comprising:
a fuselage defining an interior cabin, wherein the fuselage comprises a window system including:
at least one panel that includes an exterior surface and an interior surface;
at least one fastener extending between the exterior surface and the interior surface of the panel, wherein the at least one fastener comprises at least one optical component that is configured to allow light to pass through the at least one fastener; and
at least one screen coupled to the interior surface, wherein the at least one screen receives light from the at least one optical component of the at least one fastener.
