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 device for fluid disinfection comprising:
a handheld container configured to hold fluids, the handheld container comprising reflective internal surfaces and ultraviolet C (UVC) light blocking external surfaces; and
a lid configured to removably couple to the handheld container and retain the fluids in the handheld container, the lid comprising:
a rechargeable power supply; and
a UVC light source coupled to the rechargeable power supply, the UVC light source configured to emit UVC light for disinfection of surfaces and fluids within the interior of the handheld container.

2. The device of claim 1 , wherein the UVC light source comprises at least one of a UVC LED, UVC LED array, fluorescent bulb, or laser.

3. The device of claim 1 , wherein UVC light source is configured to deactivate in the presence of visible light.

4. The device of claim 1 , further comprising a removable filter in the handheld container configured to remove agents from the fluid.

5. The device of claim 4 , further comprising an UVC LED light source within the filter.

6. The device of claim 1 , further comprising a light amplifying device, such as a lens, adjacent the UVC light source and configured to amplify the output of the UVC light source.

7. The device of claim 1 , wherein the rechargeable power supply is configured to be recharged by at least one of wireless induction, wall charger, solar panel, or mechanical energy.

8. The device of claim 1 , further comprising a processor and a presentation interface, wherein the presentation interface is coupled to the processor and configured to present information to a user related to the disinfection of surfaces and fluids within the interior of the handheld container.

9. The device of claim 1 , wherein the fluid is water.

10. A device for fluid disinfection comprising:
a portable reservoir configured to hold fluids, the portable reservoir comprising reflective internal surfaces and ultraviolet C (UVC) light blocking external surfaces; and
a lid configured to removably couple to the portable reservoir and retain the fluids in the portable reservoir, the lid comprising:
a rechargeable power supply;
at least one UVC LED light source coupled to the rechargeable power supply, the at least one UVC LED light source configured to emit UVC LED light for disinfection of surfaces and fluids within the interior of the portable reservoir; and
a processor electrically coupled to the rechargeable power supply and in communication with the at least one UVC LED light source, wherein the processor is configured to control the at least one UVC LED light source.

11. The device of claim 10 , wherein the at least one UVC LED light source is configured to deactivate in the presence of visible light.

12. The device of claim 10 , further comprising a light amplifying device, such as a lens, adjacent the at least one UVC LED light source and configured to amplify the output of the at least one UVC LED light source.

13. The device of claim 10 , wherein the rechargeable power supply is configured to be recharged by at least one of wireless induction, wall charger, solar panel, or mechanical energy.

14. The device of claim 10 , further comprising a presentation interface coupled to the processor and configured to present information to a user related to the disinfection of surfaces and fluids within the interior of the portable reservoir.

15. The device of claim 10 , further comprising a user interface coupled to the processor and configured to receive input from a user related to the disinfection of surfaces and fluids within the interior of the portable reservoir.

16. The device of claim 10 , wherein the fluid is water.

17. A device for fluid disinfection comprising:
a handheld fluid reservoir configured to hold fluids, the handheld fluid reservoir comprising reflective internal surfaces and ultraviolet C (UVC) light blocking external surfaces; and
a lid configured to removably couple to the handheld fluid reservoir and retain the fluids in the handheld fluid reservoir, the lid comprising:
a rechargeable power supply;
a UVC LED light source coupled to the rechargeable power supply, the UVC LED light source configured to emit UVC light for disinfection of surfaces and fluids within the interior of the handheld fluid reservoir;
a user interface configured to receive input from a user;
a sensor configured to monitor visible light; and
a processor electrically coupled to the rechargeable power supply and in communication with the UVC LED light source and the sensor, wherein the processor is configured to control the UVC LED light source based on the data acquired from the sensor.

18. The device of claim 17 , wherein the processor activates the UVC LED light source when the sensor determines visible light is not present, and wherein the processor deactivates the UVC LED light source when the sensor determines visible light is present.

19. The device of claim 17 , further comprising a light amplifying device in the lid, such as a lens, configured to amplify the output of the UVC LED light source.

20. The device of claim 17 , wherein the rechargeable power supply is configured to be recharged by at least one of wireless induction, wall charger, solar panel, or mechanical energy.

21. The device of claim 17 , further comprising a presentation interface coupled to the processor and configured to present information to a user related to the disinfection of surfaces and fluids within the interior of the portable reservoir.

22. The device of claim 17 , wherein the fluid is water.
