Abstract

Enclosures that include light generating sterilization sources and conveying systems for sterilizing gaming items are disclosed. Also disclosed are gaming equipment or tables having user interface portions coated or treated with a photo-catalyst for maintaining sterility of the user interface.

Claims

1. A sterilizing unit for sterilizing gaming items comprising:

a housing;

a light generating sterilizing source;

a conveyor system having at least a first conveyor portion and a second conveyor portion, each conveyor portion placed such that a plurality of surfaces of the gaming item are directly exposed to the light generating sterilizing source; and

where the first conveyor portion includes a first plurality of seats for nesting of at least one of the gaming items, and where the second conveyor portion includes a second plurality of seats for nesting at least one of the gaming items, where the first and second conveyor portions are placed relative to one another such that movement of the gaming item from the first conveyor portion to the second conveyor portion causes the gaming item to change orientation when nested in the second conveyor portion.

2. The sterilizing unit of claim 1, where the sterilizing source comprises a UV light source located within the housing and coupled to a power supply such that the light source is configured to generate light between 100 and 400 nanometers wavelength.

3. The sterilizing unit of claim 2, where the sterilizing source provides 100,000-250,000 mWs/cm2 throughout the housing.

4. The sterilizing unit of claim 1, where the sterilizing source comprises a source of ozone in a gas state.

5. The sterilizing unit of claim 1, where the housing is portable.

6. The sterilizing unit of claim 1, where the first and second plurality of seats comprises at least one raised member attached to the respective conveyor portion.

7. The sterilizing unit of claim 1, where the first and second plurality of seats comprises at least one recess in the respective conveyor portion.

8. The sterilizing unit of claim 1, where at least one of the first and second conveyor portions comprise a linear conveyor surface.

9. The sterilizing unit of claim 1, where at least one of the first and second conveyor portions comprise a rotational conveyor surface.

10. The sterilizing unit of claim 1, where at least one of the first and second conveyor portions comprise a vibrational table.

11. The sterilizing unit of claim 1, where the housing includes a visually transparent section allowing for external viewing of the gaming items within the housing.

12. A sterilizing unit for sterilizing gaming items comprising:

a housing;

a sterilizing means;

a conveyor system having at least a first conveyor portion and a second conveyor portion, each conveyor portion placed such that the gaming item is exposed to the sterilizing source; and

where the first conveyor portion includes a first plurality of seats for nesting of at least one of the gaming items, and where the second conveyor portion includes a second plurality of seats for nesting at least one of the gaming items, where the first and second conveyor portions are placed relative to one another such that movement of the gaming item from the first conveyor portion to the second conveyor portion causes the gaming item to change orientation when nested in the second conveyor portion.

13. The sterilizing unit of claim 12, where the sterilizing means comprises a sterilizing source selected from the group consisting of UV light, gas ozone, and a combination thereof.

14. The sterilizing unit of claim 12, where the housing is portable.

15. The sterilizing unit of claim 12, where the first and second plurality of seats comprises at least one raised member attached to the respective conveyor portion.

16. The sterilizing unit of claim 12, where the first and second plurality of seats comprises at least one recess in the respective conveyor portion.

17. The sterilizing unit of claim 12, where at least one of the first and second conveyor portions comprise a linear conveyor surface.

18. The sterilizing unit of claim 12, where at least one of the first and second conveyor portions comprise a rotational conveyor surface.

19. The sterilizing unit of claim 12, where at least one of the first and second conveyor portions comprise a vibrational table.

20. The sterilizing unit of claim 12, where the housing includes a visually transparent section allowing for external viewing of the gaming items within the housing.

21. A method for providing a gaming item sterilization system, the method comprising:

creating a sterilization path having a light-based sterilization source within an enclosure;

advancing the gaming item on a conveyor through a portion of the sterilization path, such that at a plurality of surfaces of the gaming item are directly exposed to the sterilization source advancement through the sterilization path; and

directly exposing each surface of the gaming item to the light-based sterilization source for a sufficient time to significantly sterilize all surfaces of the gaming item without damaging the gaming item.

22. The method of claim 21, where directly exposing each surface of the light-based sterilization source to the light-based sterilization source comprises automatically re-orienting the gaming item so that all surfaces of the gaming item are exposed to the light-based sterilization source.

23. The method of claim 21, where the gaming item further includes a circuitry and wherein exposing the light-based sterilization source to each side of the gaming item to significantly sterilize the surface of the gaming item without damaging the circuitry.

24. The method of claim 21, further comprising applying a photocatalyst surface onto a portion of the surfaces of the gaming item such that the photocatalyst reacts with the light-based sterilization source to sterilize the surfaces of the gaming item.

25. The method of claim 21, where the sterilizing source comprises a UV light source located within the enclosure and is coupled to a power supply such that the UV light source is configured to generate light between 100 and 400 nanometers.

26. The method of claim 25, where the sterilizing source provides 10,000-250,000 mWs/cm2 throughout the housing.

27. The method of claim 21, where the enclosure is portable and further comprising re-locating the enclosure on a gaming floor.

28. The method of claim 21, where advancing the gaming item on the conveyor comprises at least advancing the gaming item on a first conveyor portion and a second conveyor portion where the conveyor portions are located such that transfer of the gaming item from the first conveyor portion to the second conveyor portion causes reorientation of the gaming item when on the second conveyor portion.

29. The method of claim 21, where the gaming item comprise an item selected from the group consisting of a casino chip, a coin. a die, and a playing card.

30. A self-sterilizing casino gaming machine for engaging a user in a casino game, the machine comprising:
