DETAILED DESCRIPTION

(12) In the following detailed description of the invention, numerous details, examples, and embodiments of the invention are described. However, it will be clear and apparent to one skilled in the art that the invention is not limited to the embodiments set forth and that the invention can be adapted for any of several applications.

(13) The device of the present disclosure may be used to clean and disinfect a variety of items and in particular, it will be appreciated that items worn by the person and re-worn by different people will find aspects of the present embodiments to be especially useful in application. For example, head worn gear such as visors, headsets, and glasses may be used amongst multiple people in for example, an amusement setting such as a virtual reality attraction or 3D movie. For sake of illustration, the following aspects will be described in the context of virtual reality (VR) applications, but it will be understood that other items that are worn multiple times and may need to be cleaned and/or disinfected may be used in embodiments of the subject disclosure without departing from the scope of invention.

(14) By way of example, and referring to FIGS. 1-10, a system for cleaning and/or disinfecting items is shown according to an exemplary embodiment. In general, aspects of the system shown clean and/or disinfect items either singularly and by a combination using ultraviolet (UV) light, pressurized air, and an antibacterial coating.

(15) For example, the system may include a chamber which in some embodiments works in tandem with a nanotech coating 55 applied to one or more surfaces of the item being cleaned. The nanotech coating may for example be applied to a surface that is designed to be in contact with a person's skin such as the face or around a user's temples. In FIG. 2, the nanotech coating 55 is applied to the inner seal of goggles that are part of a VR headset 50. The inner surface of the goggles is configured to contact against a user's face around the user's eyes when the headset is worn. As may be appreciated, this is a particularly sensitive area prone to spreading bacteria and viruses when the same item is passed on for use between people. The nanotech coating 55 isolates bacteria from each other, thus preventing biofilm creation and replication of viruses/bacteria. A UV light source 22 shines a disinfecting UV light onto at least the surfaces of the VR headset 50 that will contact users' faces. As may be appreciated, the nanotech coating 55 makes it easier for the UV light to destroy the bacteria and viruses while isolated.

(16) In an exemplary embodiment, the chamber may be a box including a lid 52 attached via a hinge 58 to an upper compartment body 54. The upper compartment body 54 may be connected to a lower compartment body 56 via another hinge 58. The chamber may also include the UV light source 22, a closed-circuit air tube 26, and power supply 42 powering electrical components such as the UV light source 22. In an exemplary embodiment, the UV light source 22 may be attached to an interior side of the lid 52. The UV light source 22 may emit a UV-C spectrum light. In an exemplary embodiment, the UV light source 22 may be a ring-shaped body that is sized to fit within an inner circumference of the headset 50. The inner circumference may be defined by the open area between the surface of the headset 50 configured for placement against the face of the user and straps or arms of the headset 50 configured to secure the headset around the head of the user. The UV light source 22 may include a plurality of UV light emitting diodes (LEDs) 46 that are positioned on an outer surface of the ring-shaped body facing the inner circumference of the headset when the headset is placed into the chamber. In some embodiments, a ventilation fan 10 may be attached to the UV light source 22 to cool down the heat that is emitted by the LEDs 46 so that the UV light source does not overheat.

(17) The closed-circuit air tube 26 may be positioned on the floor of the chamber. The chamber may also include a quick-connect port 30 that connects a compressed air source (not shown) to the closed-circuit air tube 26 via a coupler 34. In some embodiments, pressurized air from the source into the air tube 26 is controlled by a CPU 36 actuating a solenoid valve 32 positioned between the port 30 and the closed-circuit tube 26. In an exemplary embodiment, the closed-circuit air tube 26 is substantially circular with a diameter that is approximately the same size or slightly less than the inner circumference of the headset 50. The closed-circuit air tube 26 may include a plurality of vents disposed to blow air directly at the headset 50 and in some embodiments, directly at the inner seal of the goggles. The flow of air is represented by arrows 48 as shown in FIG. 10.

(18) In operation, the headset 50 may be positioned in the chamber so that the closed-circuit air tube 26 is under the headset 50. As the lid 52 is closed, the ring-shaped UV light source 22 fits within the inner circumference of the headset 50 so that the UV LEDs 46 may be within two inches or less of the headset 50 surfaces. In some embodiments, a switch 12 activates either the operation of the UV light source 22, the flow of compressed air through the closed-circuit air tube 26 or both. The UV light source 22 may destroy bacteria and viruses present on the surfaces of the headset 50. As will be appreciated, embodiments using UV-C based LEDs 46 with light distributed at close range are highly effective when used in close range (within two inches), thus reducing necessary time for disinfection and increasing the lifespan of the lights because they don't have to be activated as long. The headset 50 may then be subjected to air jet blasts through the vents of the closed-circuit air tube 26, which may knock free remaining detritus and sweat of previous users from the headset 50 surfaces and dry the surfaces so they are disinfected and ready for use by the next user. The compressed air may be pulsated through the vents in on/off intervals (such as 2 second intervals) for a predetermined period of time, such as 20 seconds by controlling the solenoid valve 32.

(19) In some embodiments, operation of the UV light source 22 and/or blasts of the compressed air through the closed-circuit tube 26 may be automatically triggered by closing the lid 52. In some embodiments, the power supply 42 is connectable to a home based current source 44 (see FIG. 9). Wiring 62 may connect the power supply 42, to the fan 10, UV light source 22, the CPU 36, and the octocoupler 38. Power is routed to any of eight switches in the octocoupler 38 which prevents power from flowing through those switches to the end devices until the CPU 36 tells the octocoupler 38 to open specific gates and allow that power to flow. The lid 52 may be moved into open/closed positions by use of a handle 18. When the lid 52 is closed, a clasp(s) 28 may secure the box closed. Some embodiments may include a magnetic lock 20 that locks onto a metal plate 60. Wiring from the magnetic lock 20 and plate 60 may trigger a closed circuit signal that may be used to trigger the automatic operation of the system as described above. Some embodiments may include a ready light 14 indicating the system is ready for operation and/or an activation light 16 indicating the system is in the process of cleaning and/or disinfecting (see FIG. 4).

(20) The above-described embodiments of the invention are presented for purposes of illustration and not of limitation. While these embodiments of the invention have been described with reference to numerous specific details, one of ordinary skill in the art will recognize that the invention can be embodied in other specific forms without departing from the spirit of the invention. Thus, one of ordinary skill in the art would understand that the invention is not to be limited by the foregoing illustrative details, but rather is to be defined by the appended claims.
