A system and method for enhancing the flux and separation properties of water filtration membranes by oxidizing raw or processed water constituents with direct photolysis of the water matrix by pulsed blackbody UV, yielding ozone and hydrogen peroxide, hydroxyl radicals and other short lived oxidizing species. The result thereof, causing precipitation of inorganic molecules or organically complexed minerals, partial or complete mineralization of organic molecules and the deactivation or destruction of microbes including: virus, bacteria and protozoa. The system and method comprises a pulsed blackbody, deep-UV reactor having at least one treatment chamber, the reactor having a conveying assembly to convey the water to be treated into the chamber; a filter assembly to screen the UV treated water; a caustic supply means for the post-treatment of water; a recovering assembly recovering the permeate at an outlet of the filtration means. The effect of such UV water treatment is multifaceted. One aspect is the reduction of the transmembrane pressure (TMP), another is the reduction of duration of backwash and caustic cleaning cycles. Also, the oxidation of iron and manganese to insoluble compounds, without the addition of oxidizing agents, does not harm the membranes. Iron and manganese turn into hydroxide crystals trapped by the filtration membrane and separated from the permeate. These effects integrate to enhance the water flux through the filter membrane.

A system for opto-pyrometric tissue temperature monitoring in real time. The system is adapted for cardiac ablation and tissue temperature measurement, having a catheter having a tip electrode adapted for RF ablation of cardiac tissue and an optical collector whose distal end is received in an opening formed in the tip electrode to detect black body radiation from the cardiac tissue. The system includes an optical detection system in communication with the optical collector, the optical processing system processing signals representative of a wavelength of at least a portion of the black body radiation to determine a tissue temperature. The incorporation of an optical collector within a catheter tip permits real time monitoring of tissue temperature during ablation and lesion formation to prevent critical thresholds in temperature associated with events that can damage tissue, including steam pop, thrombus, char, etc.

An extrudable black body decoy flare composition which, when combusted, provided black body radiation is disclosed. The compositions generally include from about 40% to about 70% metal such as magnesium or aluminum, from about 10% to about 40% polytetrafluoroethylene, and from about 8% to about 30% binder. Important to the operation of the invention is the production of carbon upon combustion of the composition. Accordingly, polyaromatic thermoplastics, such as polystyrene and dimethyl phthalate, serve as the binder.

A method and a device for reducing the extrinsic dark count of a superconducting nanowire single photon detector (SNSPD), it comprises the steps of: integrating a multi-layer film filter on the superconducting nanowire single photon detector; the multi-layer film filter is a device implemented by a multi-layer dielectric film and having a band-pass filtering function. The extrinsic dark count is the dark count triggered by optical fiber blackbody radiance and external stray light. The superconducting nanowire single photon detector comprises: a substrate having an upper surface integrated with an upper anti-reflection layer and a lower surface integrated with a lower anti-reflection layer; an optical cavity structure; a superconducting nanowire; and a reflector. The present invention is easy to operate, and only needs to integrate the multi-layer film filter on the substrate of the SNSPD to filter non-signal radiation.

An apparatus for cooking a food item therein is disclosed. The apparatus has a housing defining an interior and includes at least first and second opposed walls. A rotating member is positioned between the first and second walls of the housing, and the rotating member is capable of engaging and rotating the food item. A drive mechanism is mounted on the apparatus for rotating the rotating member. A heating element is positioned adjacent the second wall of the housing, and a blackbody radiator is positioned between the rotating member and the heating element. The heating element heats a first side of the blackbody radiator and a second side of the blackbody radiator emits radiation in a highly effective wavelength spectrum toward the food item. The apparatus also includes a self cleaning system for cleaning the interior.
