Abstract

A projection apparatus for projection in a liquid environment comprises a projection surface adapted to be positioned in the liquid environment and a projector adapted to be positioned in the liquid environment. The projector is adapted to project an image on the projection surface.

Claims

1. A projection apparatus for projection in a liquid environment, the projection apparatus comprising:

a projection surface adapted to be positioned in the liquid environment; and

a projector adapted to be positioned in the liquid environment, wherein the projector is adapted to project an image on the projection surface.

2. The projection apparatus of claim 1 wherein the projection surface includes a projection screen.

3. The projection apparatus of claim 1 further comprising a liquidproof projector enclosure wherein the projector enclosure is sized and configured to contain the projector.

4. The projection apparatus of claim 3 wherein the liquidproof projector enclosure includes a transparent wall.

5. The projection apparatus of claim 3 further comprising a heat dissipation system adapted to dissipate heat generated by the projector.

6. The projection apparatus of claim 5, wherein the heat dissipation system comprises a blower and exhaust tubing coupled to the liquidproof projector enclosure.

7. The projection apparatus of claim 5, wherein the heat dissipation system includes a corrugated high surface box forming the liquidproof projector enclosure.

8. The projection apparatus of claim 7, wherein the corrugated high surface box includes a heat conductive material.

9. The projection apparatus of claim 1 wherein the projector include a liquidproof outer casing.

10. The projection apparatus of claim 2, wherein the projection screen includes a liquid crystal microdroplet (LCMD) device.

11. The projection apparatus of claim 1 wherein the projector includes a liquidproof shell.

12. The projection apparatus of claim 1 wherein the projector includes a cooling system adapted to conduct heat through a shell of the projector into the liquid environment.

13. The projection apparatus of claim 1 wherein the projector includes a water cooling system.

14. The projector apparatus of claim 1 wherein the projector is battery operated.

15. A method of projecting an image in a liquid environment, the method comprising:

providing a projection surface adapted to be positioned in the liquid environment;

providing a projector adapted to be positioned in the liquid environment; and

projecting an image from the projector to the projection surface through the liquid environment.

16. The method of claim 15 further comprising:

containing the projector in a liquidproof projector enclosure, wherein projecting the image includes projecting through the projector enclosure.

17. The method of claim 15 further comprising:

dissipating heat away from the projector.

18. The method of claim 15 further comprising:

conducting a flow of water from the projector toward the liquid environment to dissipate heat from the projector.

19. The method of claim 15 further comprising:

containing the projector in a corrugated projector enclosure, wherein projecting the image includes projecting through the projector enclosure.

20. The method of claim 15 wherein the projector is battery operated.
