Abstract

A disinfecting system includes a housing. An ultraviolet light (UV) source is secured to the housing and configured to emit UV light for disinfection of a target. A processor is secured to the housing in communication with the UV light source. The processor is configured to activate the UV light source for a selected amount of time suitable for disinfection of the target.

First claim

What is claimed is:

1. A system comprising:
at least one ultraviolet (UV) light source configured to emit UV light for disinfection of surfaces and objects within an interior of an enclosed container, wherein the enclosed container has at least one reflective surface;
at least one of a camera and a sensor configured to acquire data from the surfaces and objects within the interior of the enclosed container during disinfection; and
a computing device in operative communication with the UV light source and the at least one of the camera and the sensor, wherein the computing device is configured to analyze the data received from the at least one of the camera and the sensor during disinfection to determine at least one parameter of disinfection, and wherein the computing device is configured to selectively control operation of the UV light source based on the determined at least one parameter of disinfection.

2. The system of claim 1 , wherein the computing device is configured to deactivate the UV light source upon receiving a signal from at least one of the camera and the sensor of the presence of a visible light.

3. The system of claim 1 , wherein the UV light source is configured to emit UV light having a wavelength from about 100 nm to about 400 nm.

4. The system of claim 1 , wherein the UV light source is configured to emit UV light having a wavelength from about 240 nm to about 260 nm.

5. The system of claim 1 , wherein the UV light source comprises at least one of a UV LED, UV LED array, fluorescent bulb, and laser.

6. The system of claim 1 , wherein the enclosed container is a refrigerator.

7. The system of claim 1 , wherein the enclosed container is a water reservoir.

8. The system of claim 1 , wherein the enclosed container is at least one of a cabinet, drawer, dishwasher, and clothes washer.

9. A system comprising:
at least one ultraviolet (UV) light source configured to emit UV light for disinfection of surfaces and objects within an interior of a refrigerator, wherein the refrigerator has at least one reflective surface;
at least one of a camera and a sensor configured to acquire data from the surfaces and objects within the interior of the refrigerator during disinfection; and
a computing device in operative communication with the UV light source and the at least one of the camera and the sensor, wherein the computing device is configured to analyze the data received from the at least one of the camera and the sensor during disinfection to determine at least one parameter of disinfection, and wherein the computing device is configured to selectively control operation of the UV light source based on the determined at least one parameter of disinfection.

10. The system of claim 9 , further comprising a visible light source configured to illuminate the surfaces and objects within an interior of a refrigerator.

11. The system of claim 10 , wherein the computing device is configured to deactivate the UV light source and activate the visible light source when a door of the refrigerator is opened.

12. The system of claim 9 , wherein the UV light source is configured to emit UV light having a wavelength from about 100 nm to about 400 nm.

13. The system of claim 9 , wherein the UV light source is configured to emit UV light having a wavelength from about 240 nm to about 260 nm.

14. The system of claim 9 , wherein the UV light source comprises at least one of a UV LED, UV LED array, fluorescent bulb, and laser.

15. A system comprising:
at least one ultraviolet (UV) light source configured to emit UV light for disinfection of fluids and surfaces within an interior of a reservoir, wherein the reservoir has at least one reflective surface;
at least one of a camera and a sensor configured to acquire data from the fluids and surfaces within the interior of the reservoir during disinfection; and
a computing device in communication with the UV light source and the at least one of the camera and the sensor, wherein the computing device is configured to analyze the data received from the at least one of the camera and the sensor during disinfection to determine at least one parameter of disinfection, and wherein the computing device is configured to selectively control operation of the UV light source based on the determined at least one parameter of disinfection.

16. The system of claim 15 , further comprising a removable filter in the reservoir configured to remove agents from the fluid, wherein the removable filter is comprised of at least one of ceramic, ceramic with a carbon core, glass fiber, structured matrix, and iodine resin.

17. The system of claim 15 , wherein the computing device is configured to deactivate the UV light source upon receiving a signal from at least one of the camera and the sensor of the presence of a visible light.

18. The system of claim 15 , wherein the UV light source is configured to emit UV light having a wavelength from about 100 nm to about 400 nm.

19. The system of claim 15 , wherein the UV light source is configured to emit UV light having a wavelength from about 240 nm to about 260 nm.

20. The system of claim 15 , wherein the UV light source comprises at least one of a UV LED, UV LED array, fluorescent bulb, and laser.
