Abstract

Apparatuses are disclosed which include one or more lamps configured to emit germicidal light, wherein the apparatuses are configured such that germicidal light emitted from the one or more lamps is projected exterior to the apparatus. The apparatuses further include wheels arranged along a bottom of the apparatus and a motor to provide automated mobility of the apparatus across at least a part of a room or area in which the apparatus is arranged. Moreover, the apparatuses include a processor and a storage medium having program instructions which are executable by the processor for activating the motor such that the apparatus is moved within the room or area while the one or more lamps are emitting germicidal light.

Claims (52)

1. An apparatus, comprising:

a discharge lamp configured to emit ultraviolet light, wherein the apparatus is configured such that ultraviolet light emitted from the discharge lamp is projected exterior to the apparatus;

a mobile carriage supporting the discharge lamp;

a push/pull handle extending from an exterior surface of the mobile carriage, wherein an uppermost surface of the push/pull handle is arranged at an elevation lower than an uppermost surface of the discharge lamp;

wheels arranged along a bottom of the mobile carriage;

a motor to provide automated mobility of the apparatus across at least a part of a room or area in which the apparatus is arranged;

a processor; and

a storage medium having program instructions which are executable by the processor for:

receiving data regarding characteristics of the room or area;

determining, based on the data, one or more operating parameters for the apparatus to perform a disinfection process in the room or area; and

activating the motor such that the apparatus is moved within the room or area while the discharge lamp is emitting ultraviolet light.

2. The apparatus of claim 1 , wherein the discharge lamp is a xenon flashlamp.

3. The apparatus of claim 1 , wherein the discharge lamp is a mercury vapor lamp.

4. The apparatus of claim 1 , wherein the discharge lamp is spaced inward from a closest outer peripheral edge of the mobile carriage by a distance greater than three times a width of the discharge lamp.

5. The apparatus of claim 1 , wherein the apparatus is configured such that the discharge lamp is moveable relative to the mobile carriage but not moveable beyond vertical planes aligned with a casing of the mobile carriage.

6. The apparatus of claim 1 , further comprising an ultraviolet light sensor, wherein the wherein the program instructions are further executable by the processor for controlling the wheels to guide the apparatus through the room or area using information obtained from the ultraviolet light sensor.

7. An apparatus, comprising:

a discharge lamp configured to emit ultraviolet light, wherein the apparatus is configured such that ultraviolet light emitted from the discharge lamp is projected exterior to the apparatus, and wherein an uppermost surface of the discharge lamp is at least 36 inches above a floor of a room or area when the apparatus is arranged on the floor of the room or area;

wheels arranged along a bottom of the apparatus;

a motor to provide automated mobility of the apparatus across at least a part of the room or area;

a processor; and

a storage medium having program instructions which are executable by the processor for activating the motor such that the apparatus is moved within the room or area while the discharge lamp is emitting ultraviolet light.

8. The apparatus of claim 7 , wherein the discharge lamp is a xenon flashlamp.

9. The apparatus of claim 7 , wherein the discharge lamp is a mercury vapor lamp.

10. The apparatus of claim 7 , further comprising a reflector assembly aligned with a longitudinal dimension of the discharge lamp and configured to redirect ultraviolet light emitted from the discharge lamp to a region exterior to the apparatus between approximately 2 feet and approximately 4 feet from the floor of the room or area in which the apparatus is arranged.

11. The apparatus of claim 7 , wherein the program instructions are further executable by the processor for altering the speed of the apparatus based on a map and dose requirements for the room or area.

12. An apparatus, comprising:

a discharge lamp configured to emit ultraviolet light, wherein the apparatus is configured such that ultraviolet light emitted from the discharge lamp is projected exterior to the apparatus;

wheels arranged along a bottom of the apparatus;

a motor to provide automated mobility of the apparatus across at least a part of a room or area in which the apparatus is arranged;

a processor; and

a storage medium having program instructions which are executable by the processor for:

activating the motor such that the apparatus is moved within the room or area while the discharge lamp is emitting ultraviolet light; and

altering a speed of the apparatus based on a map and ultraviolet light dose requirements for the room or area.

13. The apparatus of claim 12 , wherein the discharge lamp is a xenon flashlamp.

14. The apparatus of claim 12 , wherein the discharge lamp is a mercury vapor lamp.

15. The apparatus of claim 12 , further comprising a mobile carriage supporting the discharge lamp and a push/pull handle extending from an exterior surface of the mobile carriage.

16. The apparatus of claim 15 , wherein an uppermost surface of the push/pull handle is arranged at an elevation lower than the uppermost surface of the discharge lamp.

17. An apparatus, comprising:

one or more discharge lamps configured to emit ultraviolet light, wherein the one or more discharge lamps are arranged lengthwise perpendicular to a horizontal plane of the apparatus, and wherein the apparatus is configured such that ultraviolet light emitted from the one or more discharge lamps is projected exterior to the apparatus to a region which encircles the apparatus, and wherein the ultraviolet light projected to the encircling region during an operation of the apparatus collectively occupies the entirety of the encircling region;

wheels arranged along a bottom of the apparatus;

a motor to provide automated mobility of the apparatus across at least a part of a room or area in which the apparatus is arranged;

a processor; and

a storage medium having program instructions which are executable by the processor for activating the motor such that the apparatus is moved within the room or area while the one or more discharge lamps are emitting ultraviolet light.

18. The apparatus of claim 17 , wherein the one or more discharge lamps comprise a xenon flashlamp.

19. The apparatus of claim 17 , wherein the one or more discharge lamps comprise a mercury vapor lamp.

20. The apparatus of claim 17 , wherein the one or more discharge lamps are arranged in the apparatus such that uppermost surfaces of the one or more discharge lamps are at least 36 inches above a floor of the room or area when the apparatus is arranged on the floor of the room or area.

21. The apparatus of claim 7 , wherein the discharge lamp is one of multiple discharge lamps of the apparatus that are configured to emit ultraviolet light, and wherein the apparatus further includes multiple reflectors respectively disposed adjacent a different discharge lamp of the multiple discharge lamps to redirect ultraviolet light emitted therefrom.

22. The apparatus of claim 21 , wherein each of the multiple reflectors is aligned with a longitudinal dimension of its adjacently disposed discharge lamp.

23. The apparatus of claim 17 , wherein the storage medium further comprises program instructions which are executable by the processor for mapping ultraviolet light doses in the room or area as the apparatus is moved within the room or area while the discharge lamp is emitting ultraviolet light.

24. The apparatus of claim 12 , wherein the program instructions are further executable by the processor for obtaining the map of the room.

25. The apparatus of claim 12 , wherein the program instructions are executable by the processor for altering a speed at which the apparatus moves past an object in the room or area.
