Abstract

Ultraviolet radiation is directed within an area. The target wavelength ranges and/or target intensity ranges of the ultraviolet radiation sources can correspond to at least one of a plurality of selectable operating configurations including a sterilization operating configuration and a preservation operating configuration.

First claim

What is claimed is:

1. A system comprising:
a set of ultraviolet radiation sources configured to generate ultraviolet radiation directed within a storage;
an external interface configured to receive an input from a user;
a feedback component including at least one camera configured to monitor a set of current conditions of at least one of: the storage area or a set of items located in the storage area, the at least one camera including a visual camera and a fluorescent optical camera; and
a control system including means for monitoring and controlling the set of ultraviolet radiation sources by:
monitoring, using data received from the visual camera and the fluorescent optical camera, a set of current conditions of at least one of: the storage area or a set of items located in the storage area, wherein the set of current conditions includes a change in color and a presence of bacteria and/or viruses;
receiving an input from the user via the external interface; and
controlling ultraviolet radiation generated by the set of ultraviolet radiation sources using the set of current conditions and the input from the user, wherein the controlling includes adjusting at least one of: a location within the storage area to which the ultraviolet radiation is directed, a direction of the ultraviolet radiation, a time scheduling of the ultraviolet radiation, a radiation wavelength of the ultraviolet radiation, an intensity of the ultraviolet radiation, or a pattern of the ultraviolet radiation.

2. The system of claim 1 , wherein the monitoring includes detecting each item in the set of items located in the storage area.

3. The system of claim 2 , the means for monitoring and controlling further comprising adjusting the ultraviolet radiation based on the detection.

4. The system of claim 1 , the means for monitoring and controlling further comprising adjusting the ultraviolet radiation based on the detection, and wherein the information includes at least one of: a name for each item in the set of items, a location of each item located in the storage area, a history of ultraviolet radiation treatment for each item, and a status of each item.

5. The system of claim 4 , wherein the information includes a visual representation of each item located in the storage area.

6. The system of claim 5 , wherein the visual representation of each item is in real-time.

7. The system of claim 1 , wherein the storage area is divided into a plurality of regions, each region including a set of ultraviolet radiation sources that are separately controlled by the control system.

8. A food storage device comprising:
a storage area configured to store a set of items;
a set of ultraviolet radiation sources configured to generate ultraviolet radiation directed within the storage area;
an external interface configured to receive an input from a user;
a feedback component including at least one camera configured to monitor a set of current conditions of at least one of: the storage area or a set of items located in the storage area, the at least one camera including a visual camera and a fluorescent optical camera; and
a control system including means for monitoring and controlling the set of ultraviolet radiation sources by:
monitoring, using data received from the visual camera and the fluorescent optical camera, a set of current conditions of at least one of: the storage area or a set of items located in the storage area, wherein the set of current conditions includes a change in color and a presence of bacteria and/or viruses;
receiving an input from the user via the external interface; and
controlling ultraviolet radiation generated by the set of ultraviolet radiation sources using the set of current conditions and the input from the user, wherein the controlling includes adjusting at least one of: a location within the storage area to which the ultraviolet radiation is directed, a direction of the ultraviolet radiation, a time scheduling of the ultraviolet radiation, a radiation wavelength of the ultraviolet radiation, an intensity of the ultraviolet radiation, or a pattern of the ultraviolet radiation.

9. The device of claim 8 , wherein the monitoring includes detecting each item in the set of items located in the storage area.

10. The device of claim 9 , the means for monitoring and controlling further comprising adjusting the ultraviolet radiation based on the detection.

11. The device of claim 8 , the means for monitoring and controlling further comprising displaying information to the user, and wherein the information includes at least one of: a name for each item in the set of items, a location of each item located in the storage area, a history of ultraviolet radiation treatment for each item, and a status of each item.

12. The device of claim 11 , wherein the information includes a visual representation of each item located in the storage area.

13. The device of claim 12 , wherein the visual representation of each item is in real-time.

14. The device of claim 8 , wherein the storage area is divided into a plurality of regions, each region including a set of ultraviolet radiation sources that are separately controlled by the control system.

15. A refrigeration device comprising:
a storage area configured to store at least one refrigerated item;
a component configured to control at least one environmental condition of the storage area, wherein the at least one environmental condition includes at least one of: a temperature, a humidity, a gas convection, or a fluid convection;
a set of ultraviolet radiation sources configured to generate ultraviolet radiation directed within the storage area;
an external interface configured to receive an input from a user;
a feedback component including at least one camera configured to monitor a set of current conditions of at least one of: the storage area or a set of items located in the storage area, the at least one camera including a visual camera and a fluorescent optical camera; and
a control system including means for monitoring and controlling the set of ultraviolet radiation sources by:
monitoring, using data received from the visual camera and the fluorescent optical camera, a set of current conditions of at least one of: the storage area or a set of items located in the storage area, wherein the set of current conditions includes a change in color and a presence of bacteria and/or viruses;
receiving an input from the user via the external interface; and
controlling ultraviolet radiation generated by the set of ultraviolet radiation sources using the set of current conditions and the input from the user, wherein the controlling includes adjusting at least one of: a location within the storage area to which the ultraviolet radiation is directed, a direction of the ultraviolet radiation, a time scheduling of the ultraviolet radiation, a radiation wavelength of the ultraviolet radiation, an intensity of the ultraviolet radiation, or a pattern of the ultraviolet radiation.

16. The device of claim 15 , wherein the monitoring includes detecting each item in the set of items located in the storage area.

17. The device of claim 16 , means for monitoring and controlling further comprising adjusting the ultraviolet radiation based on the detection.

18. The device of claim 15 , the means for monitoring and controlling further comprising adjusting the ultraviolet radiation based on the detection, and wherein the information includes at least one of: a name for each item in the set of items, a location of each item located in the stor
