A UV C light source including a UV C bulb adapted to emit and project UV C light at a wavelength and an interchangeable UV C light modifier through which at least a portion of the UV C light emitted from said UV C bulb is projected. The UV C light modifier may be reflective, such as a reflector, perforated, holographic material, or mechanical modifier such as a barn door. The UV C light modifier might produce a narrow pattern, circular pattern, flat pattern, or asymmetrical pattern or other desired geometric pattern, or upper air pattern. The UV C light modifier is easily removed and interchanged or may be selectable such as by receiving a base UV C fixture including the UV C light source of the present invention and selecting a desired light modifier.

The communication booth includes a booth body, a wireless network module, a charger module, a germicidal lamp, a control module, and at least a sensor. The booth body includes a booth enclosure and a booth door configured to a lateral side of the booth enclosure. The wireless network module, the charger module, and the germicidal lamp are configured inside the booth enclosure. The control module is electrically connected to the germicidal lamp and the sensor. The communication booth may provide wireless network service through the wireless network module, and charging service through the charger module. The control module controls the germicidal lamp to disinfect and sterilize the booth body. The sensor may detect activities inside or around the booth body. The control module, based on the detection from the sensor, turns off the germicidal lamp so as to avoid harms to people.

A deodorizing/antibacterial/antifungal agent containing two kinds of fine particles, (i) titanium oxide fine particles and (ii) alloy fine particles containing an antibacterial/antifungal metal, gives a thin film of high transparency which has deodorizing properties and also exhibits antibacterial/antifungal properties.

The present invention provides: an interior material having a surface layer which has visible light-responsive photocatalytic activity and which contains two types of titanium oxide microparticles, the two types of titanium oxide microparticles comprising first titanium oxide microparticles, in which a tin component and a transition metal component for enhancing visible light responsiveness (excluding iron group components) are in solid solution, and second titanium oxide microparticles, in which an iron group component is in solid solution; and a method for manufacturing the interior material. The present invention makes it possible to provide an interior material in which visible light-responsive photocatalytic titanium oxide microparticles, which make it possible to easily produce a surface layer (photocatalyst thin film) having high transparency and expressing photocatalytic activity even in response to visible light (400-800 nm) only, are applied onto a surface, whereby it is possible to obtain, under indoor illumination, excellent photocatalytic properties such as an antimicrobial property and a property of breaking down chemical substances in indoor air without adversely affecting the design quality of the article in question.

UV hard-surface disinfection system that is able to disinfect the hard surfaces in a room, while minimizing missed areas due to shadows by providing multiple UV light towers that can be placed in several areas of a room such that shadowed areas are eliminated and that can be transported by a cart that is low to the ground such that the towers may be loaded and unloaded easily by a single operator. The system is able to be controlled remotely, such that during activation of the system, no operator is present, and to automatically cut power to all towers in the event that a person enters the room.

A patient warming system for stabilizing and/or heating and cooling a patient includes a plurality of solid-surface sections arranged for attachment to a surgical table and a warming pad layer comprising a plurality of warming pads configured for removable connection to the plurality of solid-surface sections. At least one of the plurality of solid-surface sections includes a power connector for connection to an external power source. Each warming pad of the plurality of warming pads includes a foam insulation layer, a distributed heating element layer having a warming-pad power connection for connection to the power connector, an isothermal layer, and a flexible waterproof layer. Power supplied to the warming-pad power connection of the distributed heating element layer of the respective warming pad can be used to provide a user-selected uniform temperature over the surface of the flexible waterproof layer in order to prevent hot spots.

A system for sterilizing biological material comprising beam generation circuitry for generating a radiating wave having radiating energy therein at a predetermined frequency therein. A controller controls the radiating wave generation at the predetermined frequency. The predetermined frequency equals a resonance frequency of a particular biological material and is determined responsive to a plurality of parameters from an influenza virus. The predetermined frequency induces a mechanical resonance vibration at the resonance frequency of the particular biological material within the particular biological material for destroying a capsid of the particular biological material. Radiating circuitry projects the radiating wave on a predetermined location to destroy the particular biological material at the predetermined location.

An improved vaporizer part, such as an evaporator element of a disinfection device is for an aqueous solution of hydrogen peroxide. The evaporator element includes one, and/or a branching, meandering structure, in which the straight sections of the groove are joined by 180-degree meanders near edges of the evaporator element. An end pit with an overflow guard is for overflown liquid. Heating elements are used both in connection with the evaporator element to enhance evaporation and on the inner surfaces of the device to prevent condensation. An air blower creates desired vortices near the surface of the evaporator element. The air control element also makes the air flow more laminar. The actual travel of the liquid on the evaporator element functions gravitationally on an inclined surface, and the capillary effect increases the evaporating area of the liquid. A disinfection device includes the vaporizer part.

Electrical connectors and fixtures, and more particularly, electrical plug and socket combinations allowing quick connection and mounting of electrical fixtures are provided with a disinfection feature for disinfecting air and/or surfaces. Additionally, lighting fixtures include or are retrofitted to provide both lighting and disinfection functions. The disinfection feature can be provided by any suitable source of UV radiation, such as an LED array. The emitted UV radiation is UV-A or FAR UV-C so that disinfection can occur regardless of whether a human is exposed to the emitted UV radiation or the emitted UV radiation is UV-C so that disinfection should only occur if there is no human exposure to the emitted UV radiation. Some electrical connectors and fixture can provide both types of emitted UV radiation, which are selectively actuatable.

A movable curtain disinfection device according to an embodiment of the present invention includes frames installed on an upper portion of a support, spaced apart from each other to face each other, and configured to define a disinfection space for a curtain provided between the frames, rotary rollers provided so that a pair of rotary rollers thereof is mounted on an inner surface of each of the frames, the rotary rollers being configured to rotate so that the curtain passes through the disinfection space, rotary belts each configured to surround an outer portion of each of the pairs of rotary rollers, the rotary belts being configured to guide a movement of the curtain while rotating in conjunction with rotations of the rotary rollers, and disinfection modules disposed between the pairs of rotary rollers and configured to disinfect the curtain passing through the disinfection space.
