The present disclosure provides for UV-responsive laminates including a first layer having a photochromatic pigment arranged as a pigment texture, or one or more photochromatic indicators, or combinations thereof. The photochromatic pigment may be disposed on the laminate during laminate fabrication, prior to installation of the laminate, or in-situ, subsequent to installation. The photochromatic pigment is configured to change from a first state to a second state in response to exposure to an ultraviolet (UV) light source, the first state is invisible to a naked eye under ambient lighting and the second state is visible to the naked eye under ambient lighting. The UV-responsive laminates may further include additional layers, such as a second layer which may be a coupling layer configured to removably couple the laminate to a component. Additional layers, such as a protective layer or a backing layer, may be included in the UV-responsive laminate as well.

The invention provides an object (10) that during use is at least partly submerged in water, the object (10) further comprising an anti-bio fouling system (200) comprising an UV emitting element (210), wherein the UV emitting element (210) comprises one or more light sources (220) and is configured to irradiate with UV radiation (221) during an irradiation stage one or more of (i) a part (111) of an external surface (11) of said object (10) and (ii) water adjacent to said part (111) of said external surface (11), wherein the object (10) is selected from the group consisting of a vessel (1) and an infrastructural object (15), wherein the object (10) further comprises a water switch (400), wherein the anti-bio fouling system (200) is configured to provide said UV radiation (221) to said part (111) in dependence of the water switch (400) being in physical contact with the water.

A washing device comprises a manifold dispenser comprising at least one liquid input and a plurality of liquid outputs that operably direct fluid to contact a plurality of laboratory consumables held by a rack in the washing device, an ultra-violet (UV) light source, and a plurality of fiber optic channels coupled to the UV light source, each of the fiber optic channels extending into a corresponding one of the liquid outputs. The plurality of liquid outputs may each comprise a nozzle having an opening into which a respective one of the plurality of fiber optic channels extends.

An apparatus for fabricating a semiconductor device may include a nozzle having a slit configured to eject solution and an ultraviolet emitter provided outside the nozzle. The ultraviolet emitter and the nozzle may be configured to move horizontally. The slit may be provided on a bottom surface of the nozzle.

A method and a device for cleaning and disinfecting a textile surface by means of UVC radiation. Furthermore, the invention relates to a disinfection box (2) generating UVC radiation. The textile surface to be cleaned is imaged before and after cleaning. On the basis of the surface area of the textile surface a duration of treatment is set. The disinfection box (2) comprises at least one UVC light source (4) of elongated shape as well as a ballast (5) to control the same. The cleaning device for cleaning and disinfecting a textile surface comprises, in addition to the disinfection box (2), a commercially available industrial vacuum cleaner (1), on the front side of which the disinfection box (2) is arranged.

An apparatus for cleaning a sample is provided. The apparatus includes an ultraviolet grid lamp having a forward side, the ultraviolet grid lamp configured to direct ultraviolet light energy from its forward side toward the sample, a quartz plate positioned between the forward side of the ultraviolet grid lamp and the sample, and a nitrogen circulating arrangement configured to circulate nitrogen along the ultraviolet grid lamp.

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.

The down and dirty sanitizer is the only product of its kind that is specifically designed to completely disinfect and sanitize dance poles, primarily used in adult entertainment, with an avant-garde UV light technology that works hand-in-hand with sound systems and a vacuum suctioning mechanism. The down and dirty sanitizer is uniquely designed with durable materials to ensure long-term sustainability and can be discreetly installed and operated in various settings where pole dancing is practiced and/or performed by varying dancers.

A laser processing machine includes a guide member with which a laser head is engaged so as to be movable to one side in a conveying direction, a moving device configured to move the laser head along the guide member, a counterweight which is movably engaged to the other side of the guide member in the conveying direction and moves along the guide member in a direction opposite to a moving direction of the laser head in conjunction with the laser head moved by the moving device, and a control device which controls the moving device to move the counterweight to a position facing the grease feeding device and to perform grease feeding to an engaged portion between the counterweight and the guide member.

A UV shielding device including a sanitizing interface having a top surface arranged to support device positioned above the sanitizing interface where the sanitizing interface includes a translucent material arranged to allow UV light to pass through. The device also includes at least one shape sensor arranged to detect a shape of a surface of the device facing the sanitizing interface. The device further includes an adjustable UV emission interface that is positioned adjacent to the sanitizing interface and arranged to adjustably conform to the shape of the surface of the device facing the sanitizing interface, while also being arranged to emit the UV light toward sanitizing interface and device.
