The present disclosure describes a pulsed ultraviolet (PUV) device and method of operating the PUV device for enhanced UV disinfection. The method may comprise generating a plurality of charging commands during an operation cycle of the PUV device. In an aspect, generating the plurality of charging commands may comprise generating a plurality of variable voltage amplitudes for charging a capacitor provided in the PUV device. The plurality of variable voltage amplitudes comprises at least one voltage amplitude greater than a cut off voltage amplitude. The method may further comprise generating a plurality of discharging commands corresponding to the plurality of charging commands for discharging the capacitor to generate IN pulses across the germicidal lamp.

An array of non-thermal plasma emitters is controlled to emit plasma based on application of an electric current at desired frequencies and a controlled power level. A power supply for an array controller includes a transformer that operates at the resonant frequency of the combined capacitance of the array and the cable connecting the array to the power supply. The power into the array is monitored by the controller and can be adjusted by the user. The controller monitors reflected power characteristics, such as harmonics of the alternating current, to determine initiation voltage of the plasma and/or resonant frequency plasma emitters. The array of non-thermal plasma emitters may be used in therapeutic, diagnostic, and/or medical sanitization applications, including where a non-thermal plasma treatment regimen for infections such as Trichophyton rubrum, or other fungal infections, is prescribed.

A sterilization device includes a shell, an air guide passage, a sterilization module and a blowing device. An opening is formed in a side of the shell to face a handrail of an escalator. The air guide passage disposed in the shell includes an air inlet communicated with an ambient space outside the shell, and an air outlet facing and communicating with the opening. The sterilization module includes a plasma generator disposed in the air guide passage and capable of ionizing air and generating high-energy particles. The blowing device is configured to force air outside the shell into the air guide passage and blow the ionized air and the high-energy particles to the handrail. The sterilization device can accurately sterilize the handrail and realize sterilization based on air ionization, so the cost is low, and a pungent odor is avoided, which brings good experience to passengers riding the escalator.

A system and method of sanitizing a package left at a doorstep safely reduces exposure to pathogens with packages. The method includes a computerized doorbell, at least one motion detector, at least one ultraviolet device, and a user (PC) personal computing device. The method begins by scanning a surrounding area of the doorway with the motion detector in order to identify at least one physical package. A delivery notification for the physical package is relayed from the motion detector, through the computerized doorbell, and to the user PC device. The delivery notification is displayed for the physical package with the motion detector. The surrounding area is further scanned with the motion detector in order to identify a human presence within the surrounding area. Ultraviolet radiation is emitted onto the surrounding area for a specified time period with the ultraviolet device, if the physical package is identified within the surrounding area.

A sensor component is sterilised for use in a system for measuring the concentration of one or more analytes in fluid in a fluid line. The sensor component comprises one or more sensing elements having an optical property that varies with the concentration of the one or more analytes in the fluid, and is configured to engage with the fluid line such that the sensing elements are exposed to the fluid. The method comprises introducing a gaseous sterilising agent into a sealed cavity via one or more ports providing fluid connection to the cavity, wherein the one or more sensing elements are exposed to the cavity, replacing the gaseous sterilising agent with a sterile liquid via the ports, and sealing the ports. Also disclosed is a sensor component with a configuration facilitating the application of the method.

It is described herein a system for disinfecting a point-of-sale terminal. The system may comprise a housing and at least one light source. The housing may be configured to connect to a first exterior surface of the point-of-sale terminal with the at least one light source mounted within a hollow interior of the housing. The at least one light source may be configured to project light in the ultraviolet spectrum of between 100 nm and 400 nm at a first angle relative to a first plane of the point-of-sale terminal upon receiving an electrical signal from a switching mechanism. The first angle may be in the range of between 0° and 90°.

Disclosed is an automatic disinfection device for a VR self-service machine, comprises two parts, a head display disinfection device, and a joystick disinfection device. The head display disinfection device comprises a light tube holder or base, a disinfecting light tube or bulb, and a power line. The disinfection light tubes or bulbs are installed on two sides of an inner wall of a VR self-service head display storage device. The joystick disinfection device in one embodiment comprises disinfecting light bulbs installed below the back plate of a VR self-service machine through a back plate attachment, and a protective cover is installed in front of the disinfecting light bulb. In another embodiment the joy sticks removably mounted on the left and right sides of the VR gaming machine are also exposed to disinfecting UV light.

Methods of decontaminating bone tissue and an apparatus or system for the same are provided. The methods can be multi-batch processes and include contacting the bone tissue having contaminants with carbon dioxide to decontaminate the bone tissue and to form carbon dioxide having contaminants. The contaminated carbon dioxide is collected and the contaminants are removed to obtain purified carbon dioxide which can be recycled to treat contaminated bone tissue. The contaminated carbon dioxide can be purified by bubbling it through water and/or an organic solvent followed by acid treatment, filtering and liquefying the carbon dioxide. Contaminants that can be removed from contaminated bone tissue, and in turn, from contaminated carbon dioxide include infectious organisms, bacteria, viruses, protozoa, parasites, fungi and mold or a mixture thereof
