Method and disinfection system for disinfecting a closed space or surface including light fixtures fixedly positioned at predefined locations in a closed space. The disinfection system includes a UV emitter module positioned over a robotic system. The light fixtures and the UV emitter module emit ultraviolet C (UVC) light for disinfecting the closed space or a surface in the closed space. The disinfection system includes sensors for measuring the amount of UVC light delivered by the light sources and UV emitter module. The disinfection system includes a control system for determining a profile for the closed space or surface based on the amount of UVC light needed and corresponding time to disinfect. The control system communicatively connects to the sensors. The control system monitors the amount of UVC light and controls the operation of the light sources and UV emitter module to deliver the required amount of UVC light.

A system and method of disinfecting an area using germicidal radiation. The system is configured to capture images of an environment, analyze the images to determine locations of a person or unprotected skin of a person in the environment, and control one or more germicidal radiation emitters to decontaminate the environment where the person or exposed skin of persons in the environment are not located. The system and method allow for safe decontamination of an environment using hazardous levels of germicidal radiation while occupied by a person who may not be fully protected from the radiation.

An item or object is exposed to electromagnetic light using a plurality of electromagnetic light emitters that are arranged throughout an enclosed structure. A plurality of images of the item or object is captured by a plurality of image sensors that are arranged throughout the enclosed structure. A first pattern in at least one image is recognized. The first pattern includes encoded information associated with the item and the first pattern is visible in response to the exposure of the item to the electromagnetic light. The encoded information is decoded and the item is identified based on the decoded information.

An UV-C device may include several UV-C light sources (e.g., UV-C LEDs) and such UV-C LEDs may have UV-C reflecting structures arranged to direct UV-C in a particular direction and at a particular size and shape. Doing so may, for example, increase the UV-C in a particular direction or working area. A UV-C generating device may be utilized in an air stream, such as an air duct, to sterilize air from that air stream. Multiple UV-C inactivation devices may be coupled in series and placed into a single housing for in order to increase the efficacy of the UV-C inactivation device. The inlet of the device may draw air using an inlet module attachment (e.g., a hood with one or more than one inlet hood) and may output air using an outlet module attachment (e.g., a duct to deliver air to an outflow air duct). Computational fluid dynamic software may be provided where UV-C inactivation devices may be positioned (e.g., manually or autonomously by an adaptive algorithm) to determine impact on airflow against various pathogens (e.g., Staphylococcus and/or SARS-CoV-2).

A laser device for dentistry has a body, a light source group, and a light guiding pipe. The body has an outer casing, an operating module, and a controlling module. The light source group is disposed in the body and has multiple light-emitting elements, a reflector, a collimating mirror, and a focusing mirror. Each light-emitting element is a laser diode, is disposed at a connecting portion of the body and is electrically connected to the controlling module. The reflector is mounted around the light-emitting elements. The collimating mirror is disposed on a side of the reflector away from the light-emitting elements. The focusing mirror is disposed on a side of the collimating mirror away from the reflector. The light guiding pipe is detachably connected to the connecting portion of the body and is located on a front side of the light source group.

An adaptable sanitizing system includes a sanitizing head including an ultraviolet (UV) lamp configured to emit UV light. One or more adapter modules are configured to removably couple to the sanitizing head at a coupling interface. The one or more adapter modules are configured to provide a functionality in relation to the UV light emitted by the UV lamp. The adapter module can include a shroud or frame that is configured to removably couple to the sanitizing head at a coupling interface, and an optical filter coupled to the shroud or the frame. The optical filter is configured to filter the UV light emitted by the UV lamp. The adapter module can include a shroud that is configured to removably couple to the sanitizing head at a coupling interface, and a fluid passage in fluid communication with an inlet and an outlet within the shroud. Fluid passes into the fluid passage through the inlet and passes out of the outlet. The UV light is emitted into the fluid passage as the fluid passes through the fluid passage between the inlet and the outlet.

The present invention relates to a device for decontaminating persons, having a container having at least one decontamination shower, the container having at least one panel defined in an opening in one of the vertical walls of the container, the panel being mounted to pivot around a horizontal hinge which joins an upper edge of the panel to the container so as to be movable between a first position in which the panel extends substantially vertically and closes off the opening, and a second position in which the panel extends substantially horizontally and forms a ceiling covering a sheltered surface. The decontamination device also includes walls capable of closing off the sheltered surface to form at least one portion of the decontamination device.

The invention relates to a mobile decontamination unit for thorough wet decontamination of persons, having a generally rectangular parallelepiped shape with a longitudinal axis and a transverse axis. The unit comprises a technical module and at least one shower module, which are adjacent to one another in the direction of the longitudinal axis. The unit also comprises a first retractable extension of the shower module in the direction of the transverse axis, on one side of said shower module, and/or a second retractable extension of the shower module in said direction of the transverse axis, on the other side of said shower module. The shower module and the one or more extensions comprise a decontamination line for persons for the circulation, in the direction of the transverse axis, of persons to be decontaminated by showering in the shower module.

Embodiments of the present disclosure provide an apparatus and a method for disinfecting an article. The method includes providing a disinfection chamber inside a cabinet. The disinfection chamber includes a tray moveable between a first position outside the cabinet for placement and retrieval of an article in the tray and a second position within the disinfection chamber for disinfection of the article. The method also includes manipulating, via a controller, a first germicidal assembly movably mounted to the disinfection chamber. The first germicidal assembly includes an articulated arm and a first UV panel mounted thereto, where the articulated arm is manipulated to extend the first UV panel in a first direction towards the article inside the cabinet for disinfecting the article.

A field of reach ultraviolet light disinfecting system includes a wrist band having two or more UV light emitters to produce a shower of UV light over the hand to disinfect pathogens that may be located on the hand and/or objects and surfaces in the light field of light dispersion the UV light emitters. A field of reach ultraviolet light disinfecting device has a top-hand UV light emitter configured on the wrist band to produce a top-hand UV light field that is emitted down over the top or back of a hand, when donned on a person's wrist. A field of reach ultraviolet light disinfecting device has a palm-hand UV light emitter that produces a palm-hand UV light field over the palm of a hand. A visible light emitter may project a visible light that overlaps the UV light field to indicate the location of the UV light emission.
