Abstract: A portal-based system for ultraviolet disinfection (UV) of containers and appliances, the system including a container with a housing having at least one portal for receiving UV light input for transmission into the container. The portal is designed such that a fiber optic transmission line is removably connectable to it. This system may include at least one portal optical component positioned between the portal and the interior of the appliance, thereby producing an enhanced sterilization of microorganisms within the container and/or appliance.

Abstract: A processing method for treating organics-containing fluids including a ultraviolet (UV) disinfection step and a biological processing step. The UV light source employed in the UV disinfection step is positioned outside the fluid to be disinfected and the fluid is disinfected via exposure to at least one UV dose zone outside the fluid being treated wherein UV light is projected into the at least one dose zone. The UV light source may be presented in a vertical riser configuration, wherein the UV light source is positioned above the fluid to be treated and projecting a UV dose zone downward toward and into the fluid to be treated, with the fluid moving upward toward the UV light source. At least one interface plate is used to provide a surface zone for UV disinfection above the fluid and to provide additional treatment means for balancing pH, affecting effluent chemistry, reducing organic chemicals, and the like.

Abstract: An ultraviolet disinfection (UV) system for gases including a UV light-ready gas purifier having at least one portal in the gas purifier for receiving UV light input from a UV light source, which is removably connected to the gas purifier via a connector at the portal, and positioned to provide a focused, controllable UV light output that has at least one UV dose zone for providing effective sterilization of microorganisms and disinfection within an interior of the gas purifier. The light source is positioned within a housing that is external to the gas purifier and capable of being connected thereto via optical connectors, such as fiber optic transmission lines. A method for UV disinfection of the interior of gas purifiers is also included in the present invention.

Abstract: A device and method for the surgical removal of tissue from a mammalian body, specifically arteriosclerotic plaques from human beings, including a photo-degradatory endoscope having a tip end and a tubular body connected to a power source, a light source, controls, and a viewer, which are remote from the tip end, the tubular body comprising a light-transmissive material such that catalyst-activating wavelengths emitted from the light source are transmitted to the tip end and through a tip into the body; and a photocatalyst for tissue degradation that is presented proximal the tip end for making a reaction with catalyst-activating wavelengths transmitted from the light source through the tubular body, through the tip, and into the body.

Abstract: An ultraviolet disinfection (UV) system for appliances including at least one UV light-ready appliance having at least one portal in the appliance for receiving UV light input from at least one light source, which is removably connected to the at least one UV light-ready appliance via a connector at the portal, and positioned to provide a focused, controllable UV light output that has at least one UV dose zone for providing effective sterilization of microorganisms and disinfection within an interior of the appliance.

Abstract: An ultraviolet (UV) disinfection system and method for treating for treating fluids including a configuration and design to function effectively with at least one UV light source or lamp that is not submerged in the fluid. The UV light source is positioned outside the fluid to be disinfected via exposure to at least one UV dose zone outside the fluid being treated wherein UV light is projected into the at least one dose zone. The UV light source may be presented in a vertical riser configuration, wherein the UV light source is positioned above the fluid to be treated and projecting a UV dose zone downward toward and into the fluid to be treated, with the fluid moving upward toward the UV light source.
