A changing table comprises a wall assembly and a tray assembly. The wall assembly comprises wall housing, a transparent-to-UV-light panel, and a UV light source. The wall assembly and tray assembly form a changeable angle α in between them. The tray assembly comprises an exterior first surface and an interior second surface. The second surface is configured to receive an infant and at least a portion of UV light generated by the UV light source.

An assembly comprising at least two elements in a movable arrangement relative to each other for performing a first function of the assembly is furthermore equipped with an anti-biofouling system for subjecting at least an area of the assembly that is to be at least partially exposed to water during at least a part of its lifetime to an anti-biofouling action as an additional function of the assembly, different from the first function of the assembly. The anti-biofouling system comprises one or more light sources for emitting anti-biofouling light, and the anti-biofouling system is adapted to realize coverage of the area with the anti-biofouling light on the basis of the movable arrangement of the at least two elements relative to each other for performing the first function of the assembly.

An apparatus for sterilizing a target includes an ultraviolet (UV) light source for emitting UV radiation for sterilizing the target, a measurement device for measuring a distance between the UV light source and the target, a controller for calculating a time duration for sterilizing the target in response to the measured distance, an attachment member for removably attaching an electronic device to the apparatus, and an interface circuit for electrically connecting the electronic device with the apparatus. The electronic device includes a processor configured to execute an application program and a display screen configured to display a result of the application program.

The present invention relates generally to the field of sanitation equipment. More specifically, the present invention relates to a shopping cart sanitation system that sanitizes shopping carts, baskets and bins that pass therethrough. The system is comprised of a tunnel-like enclosure that is comprised of a sanitization chamber and a drying chamber, wherein the sanitization chamber sanitizes carts via a spray nozzle system that sprays disinfectant as well as a plurality of UV disinfecting lights. The drying chamber dries the carts, baskets and bins via a plurality of fans before the carts exit the station and are ready for use. In one embodiment, the system may further comprise an antimicrobial station.

The present disclosure provides an apparatus for disinfecting and cleaning an electronic item.

Methods for treating substrates are described. The methods comprise the steps of flowing an aqueous liquid medium through a flow channel and at least one outlet slit onto a substrate to be treated and exposing the aqueous liquid medium to UV-radiation of a specific wavelength at least in a portion of the flow channel immediately adjacent the at least one outlet slit and after the aqueous liquid medium has flown through the outlet opening towards the substrate and thus prior to and while applying the aqueous liquid medium to the surface of the substrate to be treated. In one method, the electrical conductance of the aqueous liquid medium is adjusted to be in the range of 20 to 2000 μS, by the addition of an additive to the aqueous liquid medium, the aqueous liquid medium prior to the addition of the additive having an electrical conductivity below 20 μS, prior to or while exposing the same to the UV-radiation. Additionally, the pH of the aqueous liquid medium may be adjusted to a range of 8 to 11 or 3 to 6 prior to or while exposing the same to the UV-radiation. The adjustments may lead to a shift in an equilibrium of reactive species generated in the aqueous liquid medium by the UV-radiation towards preferred species.

In an anti-biofouling context, an anti-biofouling system (20) is provided, which is configured to emit anti-biofouling light in an activated state thereof and to be applied to an object (10). Further, the anti-biofouling system (20) comprises a sensor system (30) that is configured to obtain measurement data relating to at least one structural feature of an anti-biofouling arrangement (1) including both the anti-biofouling system (20) and the object (10) in an actual case of the anti-biofouling system (20) being in place on the object (10). By having the sensor system (30) as mentioned in the anti-biofouling system (20), it is achieved that one or more structural aspects of the anti-biofouling arrangement (1) may be checked/monitored without a need for providing separate means for fulfilling such functionality.

Systems and methods for cleaning and disinfecting contaminated tube lumens are described herein. One system includes an ultraviolet light source and a sterile fluid reservoir fluidly coupled to a liquid light guide. The system is configured to allow simultaneous access and propagation of ultraviolet light and fluid in a tube having a lumen to be cleaned and disinfected. The light guide can be moved inside the tube and simultaneously emit ultraviolet light through its walls and at its distal end into the interior of the contaminated tube. A flush of sterile fluid from an open end of the liquid light guide removes debris and micro-organism detached from the inner surface during light exposure. The sterile fluid can be a high refractive index ionic solution promoting light propagation.
