The system may still further include an oxygen tank having an outlet, and an ozone generator connected to the outlet of the oxygen tank, The system may also include a regulator and flow meter connected to the outlet of the oxygen tank and having an inlet conduit to the ozone generator to regulate a flow of oxygen into the ozone generator.

A sterilization apparatus for a portable electronic device including a cabinet and a carrier is provided. The carrier includes a base slidably disposed on the cabinet, multiple first positioning elements and multiple second positioning elements disposed in parallel on the base, multiple sterilization light sources corresponding to the second positioning elements and multiple pressure sensors disposed in parallel in the base. The base is configured to carry at least one portable electronic device. One second positioning element is disposed between any two adjacent first positioning elements, and any first positioning element and any second positioning element adjacent to each other are separated by a positioning space. The pressure sensors are respectively located in the positioning spaces. One sterilization light source is disposed between any two adjacent pressure sensors, and the pressure sensors are configured to sense a pressure from the portable electronic device.

A mobile communication device includes a pathogen disinfection apparatus including an ultraviolet (UV) light source configured to emit UV light having a mean peak wavelength between 200-280 nanometers toward a target location to at least partially inactivate pathogens exposed to the emitted UV light in the path of the emitted light and a surface of the target location. Further, the mobile communication device includes an application including processor executable instructions configured to generate signals to control the pathogen disinfection apparatus, including to operate the UV light source.

This document describes self-cleaning devices. In one aspect, a self-cleaning device includes a rigid or semi-rigid surface covered with a photocatalyst, one or more light sources disposed under or above the surface, and a triggering mechanism that activates a cleaning cycle by activating the one or more light sources.

The present invention relates to an ultraviolet sterilization box that disinfects household items such as food, electronics, wallets, keys, sunglasses, etc., and eradicates said items of germs, viruses, bacteria, and other airborne pathogens. The ultraviolet sterilization box includes a bottom surface and four walls extending vertically from the bottom surface that form an enclosed space to store a plurality of items for disinfection. A lid pivotally connected to one wall is configured to cover the enclosed space and one or more UV-C lamps on the interior surfaces of the walls, bottom surface, and the lid provide UV-C radiation from all directions to maximize the exposure of the articles within the enclosed space for sterilization. The UV sterilization box features a timing circuit that enable the UV-C lamps to automatically turn OFF after a predetermined period of time, or manually using a control button, or through a sensor.

A disinfection apparatus for treating waste may include a housing having an inlet and an outlet; a conveying mechanism which is disposed within the housing and which extends at least substantially along the housing from the inlet to the outlet; and a heating mechanism configured to transfer heat to the housing so as to heat an internal space of the housing to create a heated environment within the housing. A method of treating waste may include providing the waste in a heated environment within a housing of a disinfection apparatus; and conveying the waste, via a conveying mechanism of the disinfection apparatus, along a length of the housing of the disinfection apparatus. According to various embodiments, the method may further include heating, via a heating mechanism of the disinfection apparatus, the housing so as to heat an internal space of the housing to create the heated environment within the housing.
