Abstract

An air sanitizing apparatus for a vehicle comprising: an ozone generator; a negative ion generator; and an ultraviolet radiation source. The air sanitizing apparatus further includes a rotating feature and a motor operably connected to the rotating feature, the rotating feature configured to move the air sanitizing apparatus along a track system. The air sanitizing apparatus can includes a first end portion; a second end portion; a middle portion disposed between the first end portion and the second end portion, the middle portion rotatable relative to the first end portion and the second end portion about an axis that extends through both the first end portion and the second end portion. The ozone generator, the negative ion generator, and the ultraviolet radiation source are all disposed at the middle portion. The air sanitizing apparatus is disposed in an interior of a vehicle below but adjacent to a ceiling.

First claim

What is claimed is:

1. A method of sanitizing air in a vehicle comprising:
upon request of an anticipated passenger of a seat in a vehicle, before the anticipated passenger occupies the seat, moving an air sanitizing apparatus from a first position that is not above the seat of the vehicle to a second position above the seat of the vehicle;
causing the air sanitizing apparatus to perform at least one of the following actions: generate ozone, negatively ionize molecules in interior air, irradiate interior air with ultraviolet radiation, and irradiate a surface of the seat with ultraviolet radiation; and
moving the air sanitizing apparatus away from the second position, before the anticipated passenger occupies the seat,
wherein, the anticipated passenger requested the air sanitizing apparatus to perform the at least one action via an application program on an electronic device located outside of an interior of the vehicle.

2. The method of claim 1 , wherein
the anticipated passenger reserved the seat via the electronic device.

3. The method of claim 1 ,
wherein, the vehicle includes a track system, and the air sanitizing apparatus cooperates with the track system to move from the first position to the second position over the seat.

4. The method of claim 1 ,
wherein, the vehicle is a bus, a railway passenger car, or an airplane; and
wherein, the air sanitizing apparatus is caused to perform both the actions of: negatively ionizing molecules in the interior air and irradiating interior air with ultraviolet radiation.

5. The method of claim 1 , wherein
the air sanitizing apparatus is mounted within the vehicle.

6. The method of claim 1 , wherein
the air sanitizing apparatus comprises an ultraviolet radiation source; and
the air sanitizing apparatus irradiates interior air with ultraviolet radiation from the ultraviolet radiation source.

7. The method of claim 1 , wherein
the air sanitizing apparatus comprises an ultraviolet radiation source; and
the air sanitizing apparatus irradiates a surface of the seat with ultraviolet radiation from the ultraviolet radiation source.

8. The method of claim 1 , wherein
the vehicle comprises a ceiling, and the air sanitizing apparatus is disposed below but adjacent to the ceiling.

9. The method of claim 1 , wherein
the air sanitizing apparatus comprises a motor and a rotating feature operably connected to the motor, and the rotating feature cooperates with a track system to move the air sanitizing apparatus along the track system from the first position to the second position.

10. The method of claim 1 , wherein
the air sanitizing apparatus is caused to generate ozone.

11. The method of claim 10 further comprising:
before causing the air sanitizing apparatus to generate ozone, (i) determining that locks of the vehicle prevent access into the interior of the vehicle and (ii) determining that no occupant is occupying the interior of the vehicle.

12. The method of claim 1 , wherein
the vehicle further comprises a row of seating, of which the seat is part; and
the air sanitizing apparatus further comprises a positionable ultraviolet radiation source that can be positioned upon command to emit ultraviolet radiation to any particular seat of the row of seating.

13. A method of sanitizing air in a vehicle comprising:
upon request of an anticipated passenger of a seat in a vehicle, before the anticipated passenger occupies the seat, moving an air sanitizing apparatus from a first position that is not above the seat of the vehicle to a second position above the seat of the vehicle; and
causing the air sanitizing apparatus to perform at least one of the following actions: generate ozone, negatively ionize molecules in interior air, irradiate interior air with ultraviolet radiation, and irradiate a surface of the seat with ultraviolet radiation;
wherein, the vehicle further comprises a track system, the track system comprising a first track and a second track;
wherein, the air sanitizing apparatus further comprises (i) a first end portion that is disposed adjacent to the first track, (ii) a second end portion that is disposed adjacent to the second track, and (iii) a middle portion that is disposed between the first end portion and the second end portion; and
wherein, the middle portion of the air sanitizing apparatus is rotatable about an axis that extends through both the first end portion and the second end portion, such that the middle portion can rotate while the first end portion and the second end portion remain operably connected to the track system.

14. The method of claim 13 , wherein
one or more of the first end portion and the second end portion of the air sanitizing apparatus comprises a motor that is operably connected to a rotating feature that cooperates with the track system to move the air sanitizing apparatus.

15. The method of claim 14 , wherein
the air sanitizing apparatus further comprises (i) a housing disposed at the middle portion and (ii) a service panel disposed at a top portion of the middle portion to allow access into the housing.

16. The method of claim 15 , wherein
the air sanitizing apparatus further comprises an ozone generator, a negative ion generator, and an ultraviolet treatment module disposed within the housing at the middle portion; and
the ultraviolet treatment module comprises an air flow tube, an ultraviolet radiation source, and an exhaust fan to cause air to flow through the air flow tube, and, when activated, the ultraviolet radiation source irradiates ultraviolet radiation into the air flow tube to irradiate the air flowing through the air flow tube with ultraviolet radiation.
