Secured state is when main and secondary assemblies are secured together. Radiation assembly is configured to emit radiation, and is formed symmetrically relative to a central axis. Control assembly includes first and second safety assemblies and control processor. First safety assembly is configured to determine whether the storage system is in the secured or unsecured state. Second safety assembly is configured to determine whether the secondary assembly is in a safe or unsafe orientation state. Control processor is configured to control the radiation assembly to emit radiation when the storage system is in the secured state and the secondary assembly is in the safe orientation state.

A vehicle comprises: a dispenser for a liquid, the dispenser comprising an outlet for the liquid; and a source of ultraviolet light disposed to emit the ultraviolet light onto the outlet of the dispenser. The dispenser further comprises a first position and a second position that is different than the first position. The outlet of the dispenser is disposed closer to the source of ultraviolet light when the dispenser is in the second position than when the dispenser is in the first position. The vehicle comprises a controller in communication with the source of the ultraviolet light. The controller causes the source of ultraviolet light to emit the ultraviolet light when the dispenser is in the second position but not when the dispenser is in the first position.

A water quality measurement device 1 includes a twin tube excimer lamp 2. The inflow pipe 3 is connected to one end of the inner tube 21 of the excimer lamp 2, and the outflow pipe 4 is connected to the other end of the inner tube 21 of the excimer lamp 2. The detector 5 that measures the conductivity of sample water is interposed in the outflow pipe 4. In the water quality measurement device 1, sample water sequentially flows through the inflow pipe 3, the inner tube 21 of the excimer lamp 2, and the outflow pipe 4. Hence, the channel in the water quality measurement device 1 can be simplified. Additionally, the sample water is oxidized by being irradiated with UV light in the inner tube 21 of the excimer lamp 2. Hence, it is possible to irradiate the sample water with UV light from the excimer lamp 2 efficiently.

A handheld sanitizing device may include a housing with a first end and a second end. The housing may enclose a first cavity and a second cavity. A sanitizing light may be disposed at the first end of the housing. The sanitizing light may be configured to kill biological contaminants. A removable cap may attach to the first end and may cover the sanitizing light. An extendable agitator may extend from the first end of the housing and retract into the first cavity. A motor disposed in the first cavity may actuate the agitator. The agitator may be configured to stir a fluid. The housing may be configured to sit in a mouth of a container, extend into a reservoir of the container, and rest on the mouth of the container. A charging port may be disposed on the housing and electronically coupled to the motor and/or the sanitizing light.

A water dispenser which is connected to a pure water source and used for dispensing pure water includes: an arm mounting unit; a water dispensing gun including a nozzle for discharging pure water; a holding unit for holding the water dispensing gun; and at least two arms connecting the holding unit to the arm mounting unit. The at least two arms constitute a parallel link mechanism in which a trajectory of each arm when the at least two arms move is within the same vertical plane.

In one aspect, a sterilization apparatus is provided to include a flow channel body comprising an inflow unit configured to provide an inflow channel through which water flows in one direction, a discharge unit configured to provide a discharge channel through which water is discharged, and a bypass channel unit configured to provide a bypass channel through which water bypasses in a different direction from the direction of the water flowing in the inflow unit; a mounting unit formed on the flow channel body and configured to provide an installation space connected to the bypass channel, a UV light emitting unit disposed in the installation space and configured to emit UV light towards the bypass channel; and a holder coupled to the mounting unit and securing the UV light emitting unit inside the mounting unit.

An ultraviolet disinfection apparatus being integral to existing pipe system is provided, comprising a hollow body with at least two open ends and an arbitrary cross-section, a UV module and a control module. The hollow body is configured for receiving the UV module, and to communicate with at least one end of a pipe structure such that a medium passing therethrough will not leak. The hollow body has an inner surface and an outer surface; the inner surface includes one or more interior structures defined by one or more partition walls for sub-dividing hollow space of the hollow body into at least two relatively smaller hollow spaces. The UV module comprises one or more UV LED arrays arranged independently or severally on the inner surface and/or the interior structures to increase UV exposure to the medium. The control module is remotely connected to the UV module outside the hollow body.

An ultraviolet lamp includes a lamp tube and an electrode. A discharge cavity is formed in the lamp tube. A thermistor is disposed on an end socket at a first end of the lamp tube. A receiving groove communicated with the discharge cavity is formed in the end socket and contains amalgam. The thermistor heats the amalgam in the receiving groove in the end socket. The Curie temperature of the thermistor ranges from [T1+(T2−T1)/5] to [T1+4*(T2−T1)/5], wherein T1 and T2 are respectively a minimum operating temperature and a maximum operating temperature of the amalgam in a continuous region where the ultraviolet radiation power is from 90% to 100% when the input power of the ultraviolet lamp is 100%.

A laser ablation and filtration process and apparatus wherein liquid containing hydrocarbons or other contaminants is purified. The liquid is exposed to laser energy at one or more selected wavelengths wherein the laser energy travels through the liquid and reaches the hydrocarbons or other contaminants and vaporizes, denatures, breaks down, neutralizes, renders inert and/or separates the hydrocarbons or contaminants from the liquid. A laser source is positioned in or on a vessel based on pre-set parameters to maximize exposure of the liquid to the laser energy, including sizing parameters, angle and inclination of the laser, retention time for the laser process to be applied and geometry of the containment for proper inclination. One or more collection chambers, which may include perforated membranes may be included to collect gases, separated hydrocarbons or contaminants and other by-products of the process. The vessel utilized may be submergible in water to pull or flow contaminated water therethough. The vessel may also be utilized outside a body of water wherein contaminated water from a source is introduced within the vessel.
