US Classification:

250/455110, 422/022000, 422/023000, 422/003000, 422/105000, 422/108000

Abstract:

Methods and apparatus for precisely controlling a light treatment of a treatment system for treating a product. In one implementation, a method for use with a fluid treatment system using light comprises the steps of: estimating a particular velocity of moving particles within a fluid flowing through a treatment chamber of the fluid treatment system using pulses of light as a light treatment, the fluid flowing at a mass flow velocity, the treatment chamber and the fluid being transmissive to at least 1% of light having at least one wavelength within a range of 170 to 2600 nm; and setting a flash rate of the pulses of light based on the particular velocity in order to optimize the light treatment. Furthermore, in preferred implementations, the light treatment is for the deactivation of microorganisms, including viruses, bacteria, fungus and other pathogenic and non-pathogenic microorganisms.

US Classification:

422/022000, 422/024000, 422/186300, 250/455110

Abstract:

A fluid treatment system consists of a light source for providing light and a flexible treatment chamber having an input port and an output port, at least a portion of the flexible treatment chamber positioned to receive the light. The at least the portion of the flexible treatment chamber is transmissive to at least 1% of the light having at least one wavelength within a range of 170 to 2600 nm and the flexible treatment chamber is adapted to allow a fluid to be treated to be flowed via the input port therethrough at a specified rate and out the output port. The light source illuminates the fluid as it flows through the flexible treatment chamber in order to deactivate pathogens within the fluid. In some embodiments, the light source is a pulsed light source for emitting short duration, pulses of polychromatic light.

Abstract:

Methods and apparatus for precisely monitoring and collecting data relating to the light treatment of a product in a treatment system. In one implementation, a method for use with a treatment system using light comprises the steps of: illuminating a product with a light treatment comprising light having a spectrum of wavelengths within a range of 170 to 2600 nm, the light treatment for treating the product; and measuring a fluence of a portion of the light treatment for each of a plurality of wavelengths of the spectrum of wavelengths simultaneously. In preferred implementations, the light treatment is a pulsed light treatment and the product is a biological fluid product flowed through a treatment chamber. Furthermore, in preferred implementations, the light treatment is for the deactivation of microorganisms, such as viruses, bacteria, fungus, and other pathogenic and non-pathogenic microorganisms.

International Classification:

H05B037/00

US Classification:

31520000A

Abstract:

An apparatus, system and method are provided for use in triggering a flash lamp and treating fluids. In some embodiments, a flash lamp assembly is provided that includes a chamber that surrounds a flash lamp with first and second electrodes that extend through the chamber, and a trigger element positioned adjacent an exterior of the chamber. First and second ends of the trigger element can, in some implementations be proximate the first and second electrodes. Some embodiments provide a fluid treatment system that includes a flash lamp enclosed within a chamber, and a trigger element positioned adjacent an exterior of the chamber. The chamber include an inlet and outlet where fluid to be treated is pushed into the chamber to pass about the flash lamp without contacting the trigger element.
