Abstract

A moisture and build up removal system and method which deliver air at high velocity to the surface of a lens or a lens shield. The system and method having a particular implementation with lens surfaces of video, photographic, image viewing, and image processing devices.

Claims

1. A moisture and build up removal system comprising:

at least one air jet nozzle arranged with respect to an outer weather exposed light receiving surface of a lens, wherein said lens is integrally, or removably, formed in a body of an image processing device and said image processing device is any one of a video camera, a copier, a photographic camera, a telescope or binoculars;

an air supply; and

an air delivery system, connected to said air supply and said air jet nozzle, which delivers air from said air supply to said air jet nozzle at a velocity sufficient to push said moisture and/or build up off of an area of said surface required for an unobstructed image.

2. A moisture and build up removal system as claimed in claim 1, wherein said air jet nozzle is positioned outside of image viewing area of said lens surface.

3. A moisture and build up removal system as claimed in claim 1 wherein said air delivery system comprises a feed line connecting said nozzle to said air supply.

4. A moisture and build up removal system as claimed in claim 3 wherein said feed line is removably attached to said nozzle and to said air supply.

5. A moisture and build up removal system as claimed in claim 3 wherein said feed line is removably attached to said air supply via an adapter, said adapter providing essentially air-tight connection between said air supply and said feed line.

6. A moisture and build up removal system as claimed in claim 5 wherein said air supply has an air outlet with a cross-section different from a cross-section of said feed line.

7. A moisture and build up removal system as claimed in claim 1 wherein said lens has a funnel-shaped cover, and said jet nozzle is attached to said cover.

8. A moisture and build up removal system as claimed in claim 7 wherein a portion of said nozzle is essentially U-shaped to removably clip said portion onto said cover.

9. A moisture and build up removal system as claimed in claim 1 comprising a plurality of air jet nozzles, wherein said air delivery system connects said jet nozzles to said air supply.

10. A moisture and build up removal system as claimed in claim 1 wherein said air jet nozzles are placed in close proximity to said surface of said lens without obstructing any portion of said surface.

11. A moisture and build up removal system as claimed in claim 1 wherein said lens surface is covered by a transparent protective shield and said air jet nozzles are placed in close proximity to a surface of said shield without obstructing any portion of said lens surface.

12. A moisture and build up removal system as claimed in claim 1 further comprising a control release valve for selectively shutting off air to said nozzles from said air supply.

13. A moisture and build up removal system as claimed in claim 1 wherein said air supply is a compressed gas container.

14. A moisture and build up removal system as claimed in claim 1, wherein said system further comprises at least one clip removably attached to said body of said image processing device for securing said air supply to said body.

15. A moisture and build up removal system as claimed in claim 1, wherein said lens is integrally formed in a body of an image processing device, said system further comprising at least one clip fixedly attached to said body of said image processing device for securing said air supply to said body.

16. A moisture and build up removal system as claimed in claim 1, wherein said air supply is an electrically powered air pump or an air compressor, said system further comprising a switch for selectively turning off electric power to said air pump or air compressor.

17. A moisture and build up removal system as claimed in claim 16, wherein said switch is remotely-mounted with respect to said air supply.

18. A moisture and build up removal system as claimed in claim 1, wherein said tens is integrally formed in a body of an image processing device, said image processing device is a copier or a scanner, said lens surface is located under a transparent surface for receiving images to be scanned or copied, said nozzles are placed in close proximity to said surface for receiving images to be scanned or copied without obstructing any portion of said lens surface.

19. A method for removing, and for preventing accumulation of, moisture and/or build up on a surface, thereby keeping the view through said surface unobstructed by said moisture and/or build up, said method comprising the steps of:

positioning at least one air jet nozzle with respect to said surface, said surface being an outer weather exposed transparent image receiving surface of an image processing device which includes a lens, said image processing device being any one of a video camera, a copier, a photographic camera, a telescope or binoculars;

generating air at a velocity sufficient to remove said moisture and/or buildup from said surface; and

delivering said air to said air jet nozzle, thereby applying said air to said surface at a velocity sufficient to push said moisture and/or build up off of an area of said surface required for an unobstructed image.

20. A method for removing, and for preventing accumulation of, moisture and/or build up on a surface according to claim 19, wherein said lens is integrally formed in said image processing device.
