## Abstract

A mobile system for disinfecting a surface is described, having a chamber having an inner housing at least partially surrounding the surface, a disinfectant source at the inner housing to apply a disinfectant to at least one portion of the surface, and a motor for moving the chamber along a predetermined path from a first position to a second position, the at least one portion of the surface contacted by disinfectant changing as a result of the chamber moving from the first position to the second position.

## Claims

### Claim 1

A system for disinfecting, comprising:
a door having a door handle with a surface to be disinfected;
a chamber having an inner housing, the chamber at least partially surrounding the surface of the door handle;
an ultraviolet light source located at the inner housing to apply ultraviolet light on at least one portion of the surface of the door handle; and
a motor located on the chamber for moving the chamber along the surface of the door handle along a predetermined path along an axis of the surface of the door handle from a first position to a second position;
the at least one portion of the surface of the door handle contacted by the ultraviolet light changing as a result of the chamber moving from the first position to the second position.

### Claim 2 (depends on 1)

The system for disinfecting of claim 1, wherein the ultraviolet light is applied to the surface via a light guide.

### Claim 3 (depends on 1)

The system for disinfecting of claim 1, further comprising a dock connectable to the chamber, the dock capable of providing a resource to the chamber.

### Claim 4 (depends on 3)

The system for disinfecting of claim 3, further comprising a battery in the chamber, wherein the resource is electricity and the battery is charged by the dock.

### Claim 5 (depends on 1)

The system for disinfecting of claim 1, further comprising an actuator for starting the motor to move the chamber from the first position to the second position.

### Claim 6 (depends on 5)

The system for disinfecting of claim 5, wherein the actuator is a sensor that detects presence or non-presence of an object.

### Claim 7 (depends on 5)

The system for disinfecting of claim 5, wherein the actuator is a sensor that detects touch.

### Claim 8 (depends on 5)

The system for disinfecting of claim 5, wherein the actuator is a button or a computer.

### Claim 9 (depends on 5)

The system for disinfecting of claim 5, further comprising:
a computer;
a database accessible to the computer for storage and retrieval of scheduling data;
a user computer device in data communication with the computer;
the actuator in data communication with the computer;
the user computer device creating a command and providing the command to the computer with credentials;
the computer verifying credentials and providing the command to the actuator for disinfection.

### Claim 10 (depends on 9)

The system for disinfecting of claim 9, the actuator providing a status to the computer upon successful completion of the command.

### Claim 11 (depends on 9)

The system for disinfecting of claim 9, wherein the command is to schedule actuation.

### Claim 12 (depends on 1)

The system for disinfecting of claim 1, the chamber being closed at opposite ends along the axis of the surface to limit ultraviolet light from leaving the chamber.

### Claim 13 (depends on 12)

The system for disinfecting of claim 12, the chamber is closed by at least one gasket.

### Claim 14

A system for disinfecting, comprising:
a door having a door handle with a surface to be disinfected;
a chamber having an inner housing, the chamber at least partially surrounding the surface to be disinfected;
an ultraviolet lamp located at the inner housing to apply an ultraviolet light to at least one portion of the surface to be disinfected;
a motor for moving the chamber along the surface to be disinfected along a predetermined path along an axis of the surface to be disinfected from a first position to a second position;
the at least one portion of the surface to be disinfected contacted by the ultraviolet light changing as a result of the chamber moving from the first position to the second position;
a computer;
a database accessible to the computer for storage and retrieval of scheduling data;
a user computer device in data communication with the computer; and
an actuator in data communication with the computer;
the user computer device creating a command and providing the command to the computer with credentials;
the computer verifying credentials and providing the command to the actuator for disinfection.
