Abstract

A code reader may include a housing configured to be adjustably oriented. The housing may include at least one orientation corresponding with a cleaning function. A scanner may be disposed within the housing, and be configured to scan a machine-readable indicia in a target area. An illumination source may be configured to emit an anti-microbial illumination. A processing unit may be in communication with the scanner and illumination source, and be configured to select the cleaning function to cause the illumination source to emit the anti-microbial illumination toward the target area to disinfect surfaces in the target area.

First claim

What is claimed:

1. A code reader, comprising:
a housing configured to be adjustably oriented, said housing including at least one orientation corresponding with a cleaning function;
a scanner disposed within said housing, and configured to scan a machine-readable indicia in a target area;
an illumination source configured to emit an anti-microbial illumination; and
a processing unit in communication with said scanner and said illumination source, and configured to select the cleaning function responsive to determining that the housing is oriented according to the at least one orientation corresponding with the cleaning function to cause said illumination source to emit the anti-microbial illumination toward the target area to disinfect surfaces in the target area.

2. The code reader according to claim 1 , wherein said scanner is configured to capture an image of the target area, and wherein said processing unit is further configured to determine the orientation of said housing based on the image of the target area.

3. The code reader according to claim 2 , wherein said processing unit, in determining the orientation, is configured to identify known features disposed in a background portion of the image of the target area.

4. The code reader according to claim 1 , wherein said housing is further configured to be supported by an adjustable arm having a first position for enabling said scanner to scan machine-readable indicia and a second position associated with the cleaning function, said processing unit being configured (i) to determine that the adjustable arm is in the second position, and (ii) to cause said illumination source to illuminate.

5. The code reader according to claim 1 , wherein the anti-microbial illumination includes at least one of a blue light and an ultraviolet light.

6. The code reader according to claim 5 , wherein the blue light includes a light emitting diode that emits light at a wavelength in a range between approximately 380 nanometers and approximately 470 nanometers.

7. The code reader according to claim 5 , wherein said processing unit is further configured to emit the anti-microbial illumination in an asynchronous pattern.

8. The code reader according to claim 1 , wherein said processing unit is further configured to emit the anti-microbial illumination in combination with a red light.

9. The code reader according to claim 1 , further comprising a reflective roller shade configured to be positioned in a retracted position and a deployed position, the deployed position configured to cover the target area and illumination source.

10. The code reader according to claim 9 , wherein said processing unit is further configured to receive a signal that the reflective roller shade is in the deployed position, and communicate a signal to said illumination source to emit the anti-microbial illumination in response to said reflective roller shade being in a deployed position.

11. A method for disinfecting a target area at a code reader, comprising:
determining if an orientation of a housing inclusive of a scanner for reading machine-readable indicia is an orientation corresponding with a cleaning function; and
in response to determining that the orientation of the housing is the orientation corresponding with the cleaning function, selecting a cleaning function to cause an anti-microbial illumination to be emitted toward a target area of the scanner.

12. The method according to claim 11 , wherein emitting the anti-microbial illumination includes emitting a blue light having a wavelength between approximately 380 nanometers and approximately 470 nanometers.

13. The method according to claim 11 , wherein determining if the orientation of the housing is the orientation corresponding with the cleaning function includes sensing a change in angular orientation of the housing.

14. The method according to claim 11 , further comprising supporting the housing by an adjustable arm having a first position for enabling the scanner to scan machine-readable indicia and a second position associated with the cleaning function.

15. The method according to claim 11 , further comprising:
producing a first level of anti-microbial illumination in response to determining that the housing is in an orientation not associated with the cleaning function; and
producing a second, higher level of anti-microbial illumination in response to determining that the housing is in the orientation corresponding with the cleaning function.

16. The method according to claim 11 , further comprising producing the anti-microbial illumination in combination with the red light.

17. The method according to claim 11 , further comprising:
sensing that a shade configured to cover the target area and source of the anti-microbial illumination is deployed; and
causing the anti-microbial illumination to be at a power level higher than when the anti-microbial illumination is used for reading machine-readable indicia.

18. The method according to claim 17 , further comprising communicating a signal to all image sensors and scanners with anti-microbial illumination sources to emit the anti-microbial illumination in response to deploying the reflective roller shade.

19. The method according to claim 11 , further comprising:
in response to determining that the environmental factor is at a first value, configuring the code reader to read machine-readable indicia; and
in response to determining that environmental factor is at a second value, causing the anti-microbial illumination to be emitted toward a target area of the scanner.

20. A method for disinfecting a surface at a code reader, comprising:
sensing an environmental factor at the code reader;
in response to determining that the sensed environmental factor is at a first value, configuring the code reader to read machine-readable indicia; and
in response to determining that the sensed environmental factor is at a second value, causing an anti-microbial illumination to be emitted toward a target area of the scanner.

21. The method according to claim 20 , further comprising:
in response to determining that the environmental factor is at the first value, causing the anti-microbial illumination to be emitted at a first power level; and
in response to determining that the environmental factor is at the second value, increasing the anti-microbial illumination to be emitted at a second, higher power level.
