Abstract

Claims (31)

1. A door system comprising:

a door;

an ultraviolet (UV) light in the proximity of the door and arranged to shine at at least a portion of the door when activated, wherein the UV light is directed at the door to the exclusion of other portions of a surrounding environment;

a nozzle adjacent the door and configured to release a disinfecting fluid directed at the door when activated;

a position sensor configured to detect a position of the door; and

a controller configured to:

activate the UV light in response to a first signal from the position sensor indicating the position of the door;

detect, based on the first signal and a second signal from the position sensor, that an amount of time since the door has been used has surpassed a predetermined amount of time; and

activate the nozzle in response to detecting that the amount of time since the door has been used has surpassed the predetermined amount of time.

2. The door system of claim 1 , wherein the door is in a wall, and the UV light is mounted on the wall adjacent the door such that the UV light protrudes from the wall.

3. The door system of claim 1 , wherein the UV light is mounted in a housing disposed proximate to the door.

4. The door system of claim 3 , wherein the UV light is contained within a housing recessed in a floor proximate to the door.

5. The door system of claim 1 , wherein the controller is configured to selectively simultaneously activate the UV light and the disinfecting fluid.

6. The door system of claim 1 , wherein the controller is configured to activate the UV light and the disinfecting fluid at different times based on a mode of operation.

7. The door system of claim 1 , further comprising a secure lane, and wherein the door comprises at least one of an entry door or an exit door to the secure lane, the UV light being disposed in the secure lane and disposed to shine on at least one of the entry door or the exit door inside the secure lane.

8. The door system of claim 1 , wherein the position of the door is a closed position.

9. The door system of claim 1 , wherein the position of the door is an open position.

10. The door system of claim 1 , wherein activating the UV light includes moving the UV light, via an actuator, to be directed to a plurality of portions of the door.

11. The door system of claim 10 , wherein the UV light is directed to a first portion of the door for a longer period of time than to a second portion of the door.

12. The door system of claim 10 , wherein the UV light is directed to a first portion of the door at a higher intensity than to a second portion of the door.

13. The door system of claim 1 , further comprising space venting ducts configured to remove the disinfecting fluid from the door system after the nozzle has directed the disinfecting fluid at the door.

14. The door system of claim 1 , further comprising a disinfectant sensor configured to detect the presence of disinfecting fluid.

15. A door system comprising:

a door;

an ultraviolet (UV) light configured to shine at at least a portion of the door when activated;

a nozzle configured to release a disinfecting fluid directed at the door when activated;

a position sensor configured to detect a position of the door; and

a controller configured to:

activate the UV light in response to a first signal from the position sensor indicating the position of the door;

detect, based on the first signal and a second signal from the position sensor, that an amount of time since the door has been used has surpassed a predetermined amount of time; and

activate the nozzle in response to detecting that the amount of time since the door has been used has surpassed the predetermined amount of time.
