Abstract

An illuminated decoder is disclosed. The illuminated decoder is useful determining genuine items from counterfeit items by decoding encoded images printed on genuine items to reveal an authentication image in low light situations. The illuminated decoder includes a housing, a lens configured for optically decoding encoded images, and at least one light source attached to the housing.

Claims

1. An illuminated decoder comprising:

a housing;

a lens attached to the housing, the lens being configured for optically decoding an encoded image viewable therethrough; and

a plurality of light sources attached to the housing, all light sources being positioned within the housing to emit light through the lens to illuminate a surface containing the encoded image so that when the illuminated decoder is positioned to overlie the surface, the encoded image printed on the surface may be viewed through and decoded by the lens to reveal an authentication image to an observer positioned on the same side of the lens as the plurality of light sources.

2. The illuminated decoder of claim 1, wherein the housing comprises a top wall and at least one side wall, wherein at least one of the top wall or at least one side wall contains an aperture.

3. The illuminated decoder of claim 2, further comprising a bottom wall containing an aperture, wherein the bottom wall is configured to accept the lens.

4. The illuminated decoder of claim 3, wherein the top wall contains a top aperture for viewing the encoded image, the top aperture in a plane parallel to the lens.

5. The illuminated decoder of claim 2, wherein at least one side wall contains a side aperture for viewing the encoded image.

6. The illuminated decoder of claim 5, wherein the side aperture is in a plane orthogonal to the lens.

7. The illuminated decoder of claim 1, wherein at least one of the plurality of light sources emits light selected from the group consisting of infrared light and ultraviolet light.

8. The illuminated decoder of claim 1, wherein the plurality of light sources comprises one or more devices selected from the group consisting of incandescent bulbs, fluorescent bulbs, light-emitting diodes, and halogen bulbs.

9. The illuminated decoder of claim 1, wherein the housing comprises a shield at least partially concealing the plurality of light sources from eyes of a person viewing through the lens.

10. The illuminated decoder of claim 1, wherein the light sources are attached to the housing in a plane orthogonal to the lens.

11. The illuminated decoder of claim 1, further comprising at least one mirror attached to the housing.

12. The illuminated decoder of claim 1, wherein the lens is capable of being rotated relative to at least a portion of the housing.

13. The illuminated decoder of claim 12, wherein the housing comprises a top section and a base section, the lens attached to the base section of the housing, the base section rotatably attached to the top section to allow rotation of the base section and the lens relative to the top section.

14. The illuminated decoder of claim 1, wherein the lens is a lenticular lens.

15. The illuminated decoder of claim 1, wherein the lens is a multi-section lens.

16. The illuminated decoder of claim 1, wherein the lens has a lens frequency corresponding to a line frequency of the encoded image.

17. The illuminated decoder of claim 1, further comprising a light filter.

18. The illuminated decoder of claim 1, wherein each of the plurality of light sources emits light through the lens at a different angle.

19. An illuminated viewing device comprising:

a housing;

a lens attached to the housing, the lens being configured for viewing indicia comprising an authentication image therethrough; and

a plurality of light sources attached to the housing, all light sources being positioned within the housing to emit light through the lens to illuminate a surface to which the indicia has been applied when the illuminated viewing device is positioned to overlie the surface so an observer positioned on the same side of the lens as the plurality of light sources can view the illuminated indicia comprising the authentication image therethrough.
