A method and apparatus for sterilizing a medical instrument, such as a dental instrument. The method includes placing the medical instrument in a chamber, providing a sterilizing agent including recombined ionized humidified air, controlling the temperature of the medical instrument and/or the chamber such that the temperature of the medical instrument is below the temperature of chamber, and at least partially condensing the sterilizing agent onto the instruments.

Aspects described herein include methods, apparatuses, and non-transitory computer-readable storage mediums for operating a germicidal lighting device. A target environment is monitored for one or more people. In response to the monitoring indicating the presence of one or more people, the lighting device is caused to operate in an occupied target environment operating mode including causing the lighting device to emit far-UVC light at a given intensity into the target environment for a first period of time; and, in response to expiry of the first period of time, causing the lighting device to emit far-UVC light at a different intensity to the given intensity into the target environment for a second period of time.

Invention relates to a disinfection system which is configured for disinfecting people from the harmful bacteria and viruses that can adhere to the surfaces such as clothes, shoes. More specifically, the present invention relates to a disinfection system which allows efficient usage of the disinfectant fluid by providing maximum effect with the minimum amount of the disinfectant fluid thanks to the spraying unit that can rotate around the human body; can send the particles of disinfection liquid directly to the desired points of the body thus; does not expose the person to excessive disinfectant; moreover, creates hygienic environment for the next disinfection process after each usage by absorbing microorganisms that may be hang in the environment from the previous process thanks to the HEPA filter unit placed in the cabin. Mentioned system is a system that is effective not only on clothes, but also on human skin.

A portable UV-C disinfection apparatus, method, and system for ultraviolet germicidal irradiation. UV-C emitters may be coupled to an array housing having a planar array surface in a vertical configuration. UV-C sensors are configured to measure the amount of UV-C light or near UV-C light from a target surface. A controller may be communicably engaged with the UV-C sensors to determine the amount of UV-C radiation collected by the UV-C sensors. The controller includes instructions stored on a memory according to the amount of UV-C radiation collected corresponding to an effective kill-dose for surface disinfection. The improved apparatus, method, and system reduces exposure time by varying the intensity and wavelength of the UV-C administered, while concurrently reducing UV overexposure to surfaces by administering radiation through a rotational zonal application.

Provided are systems and methods for treating a biological fluid, e.g., to inactivate pathogens.

A valuable media sanitizing/cleansing cassette is provided for sanitizing/cleansing surfaces of valuable media dispensed to a consumer during a dispense transaction at a transaction terminal. Dispensed media is urged from one or more media cassettes within the terminal along a transport path. The transport path is altered to pass the media through the sanitizing/cleansing cassette where the top and bottom surfaces of the media are illuminated with Ultraviolet (UV) radiation to eradicate any bacteria or virus that may be adhered to the top or the bottom surfaces of the media. Once the media passes through the sanitizing/cleansing cassette, the now sanitized/cleansed media is urged along a remainder of the transport path and dispensed from a media interface of the terminal to the consumer. In an embodiment, media deposited at the terminal is also sanitized/cleansed by passing through the sanitizing/cleansing cassette before being stored in the appropriate media cassettes.

An exhaust conduit for a cargo vessel. The exhaust conduit is a flexible conduit with a first upstream opening adapted to engage with an exhaust structure and a second downstream opening for exhausted air. The exhaust conduit is inflatable due to the passage of exhausted air and the downstream opening is of smaller cross-sectional area than the upstream opening. The downstream opening is of adjustable cross-sectional area. In a system for fumigating a RORO vessel, the inflatable exhaust is inflatable to a height exceeding the height of the accomodation block. In a method of fumigating a RORO vessel, the method includes providing a temporary flexible exhaust for exhausting fumigant from the cargo area, and/or providing an inflatable exhaust for exhausting fumigant from the cargo area.

The invention is directed to a system for preventing or minimizing the spread of viruses, and to the prevention or minimization of the spread of viruses in indoor air, including one or more radiation sources (10) in a room which divide the room into smaller segments using UV-C light walls, a sensor system for detecting a movement or a presence of one or more persons (P) in the room, and a controller (16) that is designed to at least partially switch the one or more radiation sources (10) on or off as a function of at least the presence of the person (P).

According to the invention, the one or more radiation sources (10) are designed to generate a wall-type radiation field (10b) that acts as a UV-C wall, so that the room or rooms is/are divided into smaller room segments, which prevents or minimizes the spread of viruses due to the fact that the viruses are deactivated by the UV-C light, and the controller (16) is designed to at least partially switch off the radiation source (10) in question if the movement data detected by the sensor system indicate a likelihood that one of the persons (P) would like to pass through the radiation field (10b) in question.
