The present invention offers infectious virus mitigation apparatus that utilize one or more 3-dimensional porous metal substrate that impart virus mitigation effect. Fluid that contains or may contain infectious virus traverses through said substrate to achieve virus mitigation effect. Additional virus mitigation effect can be achieved by subjecting said virus mitigation apparatus to suitable wavelength(s) of light that enhance total virus mitigation effect and/or utilizing contoured cover glazing to induce fluid dynamics that can enhance total virus mitigation effect per pass of said fluid through said apparatus. The utility includes a wide variety of practical uses such as filtration of air, water, blood, and other fluids that contain or may contain infectious virus such as coronavirus.

A dehaze and bacteriostatic film includes a substrate material layer and a composite surface plasmon layer formed on the substrate material layer. The composite surface plasmon layer includes a particle stacked film layer and a particle suspension layer located on the substrate material layer, and the particle stacked film layer and the particle suspension layer jointly generate a composite surface plasmon wave. Accordingly, the composite surface plasmon wave is excited by visible light, so that different types of surface plasmon waves generated by the structures resonate and multiply with each other. The different surface plasmon waves add up to generate electromagnetic field intensity capable of dissociating spatial materials at a certain distance, such as water vapor to be partially ionized which is rich in hydroxide ions with effects of dehazing and inhibiting growth of bacteria.

A station for a handheld information device (HID) includes a station body having a periphery and a receiving surface to support at least a portion of the HID. A visible antimicrobial illumination (VAI) emitter is coupled to the station body and arranged to direct a human-visible illumination beam at a target surface of the HID to produce an antimicrobial effect on the target surface. At least a first portion of the target surface is external to the periphery of the station body, and the human-visible illumination beam is projected beyond the periphery to illuminate the first portion of the target surface.

This document describes self-cleaning devices. In one aspect, a self-cleaning device includes a fabric having a surface covered with a photocatalyst, one or more light sources embedded in the fabric, and a triggering mechanism that activates a cleaning cycle by activating the one or more light sources.

The triggering mechanism can be configured to activate the cleaning cycle in response to detecting a decrease in pressure being applied to the pressure sensor.

A lighting assembly includes a lightbulb, sleeve, motor assembly, a control circuit, power source, first state, and second state. The control circuit is communicatively coupled to the power source, the lightbulb, and the motor assembly. The lightbulb emits ultra violet (“UV”) radiation. The sleeve converts UV radiation to visible light, is circumferentially positioned about the lightbulb, and is rotatably coupled to the lightbulb via the motor assembly. The motor assembly is mechanically coupled to the sleeve, and selectively rotates the sleeve about the lightbulb and thereby positions the lighting assembly in the first state or the second state. The sleeve includes a slit that emits the UV radiation from the lightbulb. In the first state, the lighting assembly emits UV radiation towards a surface. In the second state, the lighting assembly emits visible light towards the surface.
