An assembly for removing odors from items having a first container formed from a material that is at least partially ozone impervious and that defines a first interior that is accessible via a selectively closeable opening, an ozone generator that is adapted to generate and expel ozone gas from the ozone generator into the first interior of the first container, and a fastening mechanism for selectively maintaining the selectively closeable opening in a closed orientation in which the fastening mechanism prevents access to the first interior. In various embodiments, when the selectively closeable opening is in the closed orientation and the ozone generator expels ozone into the first interior of the first container, the ozone concentration in the first interior is at a concentration of between 1 ppm and 2000 ppm and the ozone leakage from the first container is between 0.01 ppm and 0.03 ppm of ozone.

Liquid dispensing systems which automatically sanitize the liquid and liquid-contacting parts of a liquid dispensing system, by periodically flushing the system with a sufficiently heated, liquid and/or gas.

Apparatus, system, and methods are provided for reducing infectious agents at a sterile site by preventing infectious agents from coming into contact with the sterile site. A barrier is produced for infectious agents that may come in proximity or otherwise communicate with the site. The apparatus is configured to create a void-free barrier in which infectious agents are reduced with minimal exposure of potentially harmful effects of the barrier to the sterile site, objects, or users of the apparatus.

A multi-layer bag comprising a porous portion configured to allow a sterilizing gas to penetrate into the bag and a gas-impervious portion, characterized in that the gas-impervious portion comprises an outer layer, an inner layer and an intermediate layer integrally formed together so that the intermediate layer is sealingly enclosed between the outer layer and the inner layer so as to be physically isolated from inner and outer environment of the bag, and the intermediate layer comprises a matrix and at least one pigment distributed within the matrix, the pigment being configured to change at least one optical property in reaction to an environment change resulting from a damage of the outer and/or inner layer.

An UV disinfection system (200) may feature a chamber (207) with internal spherical reflective surfaces (208) to evenly reflect UV radiation from all angles to direct the UV radiation to all surface area of the object inside the chamber to disinfect object utilizing UV radiation under controlled time. An object (215) to be disinfected may reside within the chamber (207) on a UV transparent rack or shelf (214). The spherical reflective surfaces may be fashioned by placing such surfaces on a polyhedral internal structure or making the internal chamber spherical in and of itself (208). Multiple UV sources (209a), (209b) may also be utilized.

The present invention relates to a radiation generating system (1) comprising a radiation unit (2), wherein the radiation unit (2) comprises a light source (3), a first collimator (4), and an optical arrangement (5). The light source (3) is configured to generate light source radiation (100) having a first spectral power distribution having an intensity I.sub.1,1 at a first wavelength .sub.1 and an intensity I.sub.1,2 at a second wavelength .sub.2. The first collimator (4) is configured in a light receiving relationship with the light source (3), wherein the first collimator (4) is configured to collimate the light source radiation (100) into collimated light source radiation (101) having an initial spatial light distribution (ISLD). The optical arrangement (5) is arranged downstream of the first collimator (4) and comprises an optical filter (6) and a diffuser (7). The optical filter (6) has a higher transmission for the first wavelength .sub.1 than for the second wavelength Xi when irradiated under a predefined angle 0. The first wavelength Xi is selected from the range of 190-230 nm and the second wavelength Xi is selected from the range of 100-190 nm and/or 230-300 nm. The optical filter (6) is configured to filter at least part of the collimated light source radiation (101) into filtered radiation (102) comprising at least portion of the light source radiation (100) of the first wavelength Xi having a first spatial light distribution (SLD1) and at least portion of the light source radiation (100) of the second wavelength .sub.2 having a second spatial light distribution (SLD2) different from the first spatial light distribution (SLD1). The diffuser (7) is configured downstream of the optical filter (6). The diffuser (7) is configured to diffuse at least part of the filtered radiation (102) into diffused radiation (103) comprising at least a portion of the light source radiation (100) of the first wavelength .sub.1 having a third spatial light distribution (SLD3) and at least portion of the light source radiation (100) of the second wavelength .sub.2 having a fourth spatial light distribution (SLD4) different from the second spatial light distribution (SLD2).
