An applicator wand for the cosmetic product is optically coupled to an ultraviolet light source as an illumination source of ultraviolet light wavelengths. The applicator wand provides the source of the ultraviolet light wavelengths to be a germicide for bacteria in the cosmetic product on the applicator wand. The ultraviolet light source emits the ultraviolet light wavelengths in a range extending between 202-225 nm. A container contains the cosmetic product. The cap of the container attaches to a body of the container. One or more batteries electrically connect to at least an electronic control circuit and the ultraviolet light source.

A sanitizing apparatus sanitizes headsets or eyeglasses between uses by patients. The apparatus includes a UV-C lamp that generates UV-C light at a proper frequency and intensity during a time period of sufficient duration to kill bacterial and viral infectants on surfaces of the headsets or eyeglass frames that may come in contact with a patient's skin. The apparatus may also be used for sanitizing bone vibrators, otoacoustic emissions testing equipment, headsets used in impedance testing, insert earphones, and response buttons that are commonly used in audiometric testing. The apparatus can also be used in communication situations in which headsets are utilized with microphones, such as in call centers.

A system for sterilizing viruses includes beam generation circuitry for generating a radiating wave having radiating energy therein at a predetermined frequency therein. A controller controls the radiating wave generation at the predetermined frequency. The predetermined frequency equals a resonance frequency of a particular virus. The predetermined frequency induces a mechanical resonance vibration at the resonance frequency of the particular virus within the particular virus for destroying a capsid of the particular virus. Radiating circuitry projects the radiating wave on a predetermined location to destroy the particular virus at the predetermined location.

Embodiments of the present disclosure disclose a multipurpose ultraviolet (UV) floor curing device. The device includes a mobile carriage, a UV panel, and a control device. The mobile carriage is configured to move on a floor applied with a photocurable coating. The UV panel is coupled to the mobile carriage and removably secures a plurality of radiation units configured to emit UV light of a predetermined intensity capable of curing the photocurable coating. The UV panel is configured to transition between a floor configuration and a non-floor configuration. The control device configured to drive the UV panel for the plurality of radiation units to project the UV light towards the ground substantially underneath the UV panel in the floor configuration and towards elevated surfaces proximate to the ground in the non-floor configuration.

A self-sterilizing display device is applied to self-sterilizing with a UV light. The self-sterilizing display device includes a display, a light-incident layer, a light source, and a turning layer. The light-incident layer is disposed above the display. The light source is disposed at a periphery of the light-incident layer, and a light-emitting surface of the light source faces to the light-incident layer. The turning layer is disposed on a lower surface of the light-incident layer. Herein, the light source can emit the UV light toward the light-incident layer for sterilizing an outer surface of the self-sterilizing display device by irradiation, and the turning layer can change the direction of an optical path of the UV light. Therefore, the surface can be sterilized by UV light, and the UV light can be prevented or reduced from being incident on the display below and damaging the display.

The invention relates to a device for accommodating and disinfecting a writing instrument (4), comprising at least a housing (1) having a chamber with at least one opening for placing or inserting the writing instrument (4) in the chamber, the chamber being an illumination chamber (2) equipped with UV light sources (3) that irradiate the entire outer surface of the placed or inserted writing instrument (4).

Systems and methods for operating a cart. The methods comprise: receiving an electronic device on a shelf disposed in a main chamber of the cart; supplying power from the cart to the electronic device; transitioning a mode of the cart from a first mode in which a UV lamp is disabled to a second mode during which the UV lamp is to be enabled; detecting, by a computing device, that a door of the cart is in a closed position; causing, by the computing device, an enablement of the UV lamp, responsive to a detection that the door is in the closed position; and using light from the UV lamp to clean the surface of the electronic device while power is being supplied from the cart to the electronic device.

An ultraviolet light sterilization device for treatment of plant materials, having a rotational treatment chamber having an axis of rotation and at least one mechanical agitation element, an ultraviolet light device that is positioned inside the rotational treatment chamber and is further positioned generally parallel to and congruent with the axis of rotation and where the ultraviolet light device and the rotational treatment chamber are connected to one another via a rotational bearing such that the rotational treatment chamber may be rotated about the axis of rotation while the ultraviolet light device does not rotate, and where the ultraviolet light device is electrically coupled to a power source via an electrical cable that passes through an aperture in the rotational bearing.

A continuous flow sterilization system includes an inclined treatment chamber having a first end and a second end. An ozone generator generates a flow gas containing ozone; an input opening to receive a bulk material into the treatment chamber. An input port is provided for introducing the flow gas containing of ozone into the treatment chamber. A first sensor measures a level of ozone in the gas output of the treatment chamber. The other sensors measure ozone concentration and temperature within the treatment chamber. An output opening provides an exit for the bulk material. An output port provides an exit for the flow gas. An auger is disposed within the treatment chamber to move the bulk material through the treatment chamber.
