Abstract

UV hard-surface disinfection system that is able to disinfect the hard surfaces in a room, while minimizing missed areas due to shadows by providing multiple UV light towers that can be placed in several areas of a room such that shadowed areas are eliminated and that can be transported by a cart that is low to the ground such that the towers may be loaded and unloaded easily by a single operator. The system is able to be controlled remotely, such that during activation of the system, no operator is present, and to automatically cut power to all towers in the event that a person enters the room.

Claims

1. A disinfection system comprising:

a plurality of independently placeable energy emitter assemblies, each of the assemblies including;

a base;

an elongate energy emitter extending vertically from said base;

a communications module;

a controller in data communication with each of the communications modules of the plurality of energy emitter assemblies;

wherein said controller is capable of remotely controlling activation and

deactivation of said plurality of energy emitter assemblies.

2. The disinfection system of claim 1 wherein said base comprises a plurality of wheels extending downwardly from a bottom of said base.

3. The disinfection system of claim 1 wherein said elongate energy emitter comprises a tower.

4. The disinfection system of claim 1 further comprising a cap attached to a top of said energy emitter assembly.

5. The disinfection system of claim 2 further comprising a push ring assembly extending from said base for use in conjunction with said wheels to move said energy emitter assembly over surfaces without applying pressure to said elongate energy emitter.

6. The disinfection system of claim 5 wherein said push ring comprises a handle and a plurality of supports.

7. The disinfection system of claim 6 wherein said plurality of supports comprises a plurality of telescoping supports.

8. The disinfection system of claim 1 wherein said base comprises a housing.

9. The disinfection system of claim 8 wherein said housing contains power circuitry for said elongate energy emitter.

10. The disinfection system of claim 4 wherein said cap comprises a safety feature capable of shutting off said plurality of independently placeable light towers if movement is detected in said space.

11. A method for disinfecting an enclosed space comprising:

providing a plurality of independently placeable energy emitter assemblies each of the assemblies including;

a base;

an elongate energy emitter extending vertically from said base

a cap located on top of said elongate energy emitter; and

,

a communications module;

positioning at least one of the plurality of independently placeable energy emitter assemblies throughout an enclosed space;

establishing data communication between a controller and the at least one of the plurality of independently placeable energy emitter assemblies;

remotely energizing the at least one of the plurality of independently placeable energy emitter assemblies;

scanning said space for movement using a safety feature at least partly located in said cap;

shutting down said at least one of the plurality of independently placeable energy emitter assemblies if said safety feature detects movement in said space.

12. The method of claim 11 wherein the step of positioning at least one of the plurality of independently placeable energy emitter assemblies throughout an enclosed space comprises determining a positioning of said at least one of the plurality of independently placeable energy emitter assemblies that minimizes the creation of shadows.

13. The method of claim 11 wherein said base comprises wheels and a handle and wherein the step of positioning at least one of the plurality of independently placeable energy emitter assemblies throughout an enclosed space comprises pushing the handle.

14. The method of claim 11 wherein establishing data communication between a controller and the at least one of the plurality of independently placeable energy emitter assemblies comprises employing a wireless network.

15. A hard-surface disinfection system comprising:

a plurality of independently placeable ultraviolet light emitting towers, each including a base and at least one ultraviolet light emitter extending vertically from said base;

wherein each of the plurality of independently placeable ultraviolet light emitting towers is capable of being controlled remotely by a common wireless controller;

wherein each of the bases comprises wheels and a handle.

16. The hard-surface disinfection system of claim 15 further comprising connectors attached to said bases constructed and arranged such that each of the bases may be connected together, allowing the plurality of independently placeable ultraviolet light emitting towers to be connected and rolled as a single unit.

17. The hard-surface disinfection system of claim 15 wherein each of the plurality of independently placeable ultraviolet light emitting towers further includes a cap attached to a top thereof and containing a motion detector.

18. The hard-surface disinfection system of claim 17 wherein each of the plurality of independently placeable ultraviolet light emitting towers comprises a communications module capable of at least receiving data from a common wireless controller.

19. The hard-surface disinfection system of claim 17 wherein each of the plurality of independently placeable ultraviolet light emitting towers comprises a communications module capable of sending data.

20. The hard-surface disinfection system of claim 17 wherein each of the plurality of independently placeable ultraviolet light emitting towers comprises a communications module allowing each of said independently placeable ultraviolet light emitting towers to communicate with each other.
