Abstract

In accordance with an example embodiment, there is disclosed herein, an apparatus, comprising a bezel, a cover, and a thermally conductive, electrically isolating material. The cover comprises top and side surfaces, a cavity for receiving an optical device, a first opening for the optical device to obtain an image, and a second opening for allowing an electrical conductor to be coupled with the optical device. The thermally conductive, electrically isolating, material, is shaped in accordance with the shape of the optical device. The bezel and the cover protect the optical device from discharge currents. The thermally conductive, electrically isolating, material provides electrical isolation of the optical device from the cover and conducts heat from the optical device to the top and side surfaces of the cover.

First claim

The invention claimed is:

1. An apparatus, comprising:
a L shaped bezel;
a cover that comprises a cavity for receiving an optical device, a first opening for the optical device to obtain an image, and a second opening for allowing an electrical cable to be coupled with the optical device;
a L shaped cover gasket coupled with the L shaped bezel; and
a thermally conductive, electrically isolating, material, shaped in accordance with a shape of the optical device;
wherein the L shaped bezel engages the cover to form an enclosure, the bezel forming the bottom and front surface of the enclose, and the cover forming the top, left, right, and rear sides of the enclosure;
wherein the L shaped cover gasket seals the contacts between the L shaped bezel and the cover, and the L shaped cover gasket provides electrical isolation between the bezel and the optical device;
wherein the bezel and the cover protect the optical device from discharge currents; and
wherein the thermally conductive, electrically isolating, material provides electrical isolation of the optical device from the cover and conducts heat from the optical device to the top and side surfaces of the cover.

2. The apparatus set forth in claim 1 , further comprising the optical device.

3. The apparatus set forth in claim 2 , wherein the optical device is a two dimensional barcode scanner.

4. The apparatus set forth in claim 1 , further comprising:
an optical window located between the optical device and the bezel; and
a window gasket that seals the optical window with the bezel.

5. The apparatus set forth in claim 1 , wherein the cover allows electrical discharge currents to flow to a surface ground cable.

6. The apparatus set forth in claim 1 , wherein the cover dissipates heat from the optical device conducted by the thermally conductive, electrically isolating, material to external air.

7. The apparatus set forth in claim 1 , further comprising:
a grommet located at the second opening;
wherein the second opening is operable to receive an electrical conductor that couples the optical device with an external device; and
wherein the grommet protects the electrical conductor from electrical discharges.

8. The apparatus set forth in claim 1 , further comprising a bezel gasket operable to form a seal between the apparatus and an external device.

9. An apparatus, comprising:
a L shaped bezel;
a cover;
wherein the bezel and cover form an enclosure, the bezel forming front and bottom surfaces of the enclosure, and the cover forming the top, left, right and rear surfaces of the enclosure;
a L shaped cover gasket coupled with the L shaped bezel, the cover gasket providing a seal between the bezel and the cover, and the cover gasket provides electrical isolation between the bezel and an optical device within the enclosure;
the front surface of the enclosure having an opening;
an optical window;
a window gasket disposed between the optical window and the front surface of the bezel, the optical window is disposed between the window gasket and the cover gasket;
the cover having an opening at one of a group consisting of the right, left, and rear surface for receiving a cable;
a grommet providing a seal between the one of the group consisting of the right, left, and rear surface and the cable, the grommet electrically isolating the cable from the one of the group consisting of the right, left, and rear surface and protecting the cable from electrical discharges from the cover; and
a thermally conductive, electrically isolating, material, shaped in accordance with the shape of the optical device, the thermally conductive, electrically isolating, material provides electrical isolation of the optical device from the cover and conducts heat from the optical device to the top and side surfaces of the cover;
wherein the enclosure forms a Faraday cage and electrical isolates the optical device within the enclosure and protects the optical device from electric discharges on the bezel and the cover.

10. The apparatus set forth in claim 9 , further comprising the optical device.

11. The apparatus set forth in claim 10 , wherein the optical device is a two dimensional barcode scanner.

12. The apparatus set forth in claim 9 , wherein the cover dissipates heat from the optical device conducted by the thermally conductive, electrically isolating, material to external air.

13. The apparatus set forth in claim 10 , wherein the bezel and cover are constructed from an electrically conductive material.

14. The apparatus set forth in claim 11 , wherein the cover gasket is positioned to provide increased pressure to the optical window to provide increased resistance against wind and precipitation.

15. The apparatus set forth in claim 12 , the cover comprises fins with mounting holes to facilitate mounting of the enclosure on to an external device, the fins attached to the right and left sides of the enclosure.

16. The apparatus set forth in claim 13 , further comprising a front gasket that seals the enclosure with an external device.
