Abstract: A method of filtering a fluid includes flowing a fluid into a filter assembly. The filter assembly includes a vessel defining a pressure chamber and a filter screen disposed within the vessel. The screen divides the pressure chamber into a first subchamber and a second subchamber. In addition, the method includes flowing the fluid from the first subchamber to the second subchamber, and controlling a first pressure of the first subchamber relative to a second pressure of the second subchamber to induce cavitation in the flowing fluid. Further, the method includes precipitating out dissolved impurities within the fluid during the cavitation.

Abstract: A method of filtering a fluid, including flowing a fluid from a first side of a filter member to a second side of the filter member, the fluid containing dissolved impurities. In addition, the method includes inducing fluid cavitation within the fluid to precipitate out at least a portion of the dissolved impurities. Further, the method includes controlling a pressure differential across the filter member. Still further, the method includes, maintaining or further inducing the fluid cavitation within the fluid in response to controlling the pressure differential. Related systems are also disclosed.

Abstract: A rotating detonation combustion system includes an outer wall and an inner wall together defining at least in part a combustion chamber and a combustion chamber inlet. A nozzle of the rotating detonation combustion system is located at the combustion chamber inlet, the nozzle defining a lengthwise direction and extending between a nozzle inlet and a nozzle outlet along the lengthwise direction. The nozzle further defines a throat between the nozzle inlet and nozzle outlet. A fuel injection port is also provided, the fuel injection port defining a fuel outlet located between the nozzle inlet and the nozzle outlet for providing fuel to a flow of oxidizer received through the nozzle inlet.

Abstract: An apparatus for computing a bid price for a plurality of items includes an input portion, a processing portion, and an output portion. The input portion is adapted to electronically receive a bid for an online auction listing for a plurality of items, the bid including a limit price and an initial bid price for each of the plurality of items, and a total bid price for an entirety of the plurality of items. The processing portion is adapted to electronically compute a bid price for each of the plurality of items, such that a sum of the computed bid prices for the plurality of items is substantially equal to the total bid price. The output portion is adapted to electronically transmit the computed bid prices for the plurality of items to an online auction portion, the online auction portion accepting the bid in accordance with the computed bid prices.

Abstract: Disclosed herein are compositions and methods for incorporating non-native amino acids into a single polypeptide. In one example, an isolated modified suppressor tRNA is disclosed that includes the following: a modified tRNAcys, wherein the tRNAcys has been modified so that an anticodon of the tRNA is complementary to a stop codon; a cysteine amino acid residue is covalently linked to the modified tRNAcys by aminoacylation generating a chemically reactive sulfhydryl side chain; and a detectable label is covalently linked to the sulfhydryl side chain. Methods for incorporating non-native amino acids into a single polypeptide utilizing the disclosed isolated modified suppressor tRNAs are also disclosed.

Abstract: A novel image sensor structure formed on a substrate of a first conductivity type includes a photosensitive device of a second conductivity type and a surface pinning layer of the first conductivity type. A trench isolation region is formed adjacent to the photosensitive device pinning layer. The structure includes a dopant region comprising material of the first conductivity type formed along a sidewall of the isolation region that is adapted to electrically couple the pinning layer to the substrate. The corresponding method facilitates an angled ion implantation of dopant material in the isolation region sidewall by first fabricating the photoresist layer and reducing its size by removing a corner, or a corner portion thereof, which may block the angled implant material. To facilitate the angled implant to the sidewall edge past resist block masks, two methods are proposed: 1) a spacer type etch of the imaged photoresist; or, 2) a corner sputter process of the imaged photoresist.

Abstract: An automated fiber preparation system and method for automatically fabricating an optical fiber. One or more fabrication processes associated with fiber preparation may be performed on an optical fiber without requiring active user input. The fiber preparation system may be configured to automatically carry out each of the process steps for fabricating an optical fiber pigtail. The fiber preparation system may include a fiber preparation module that is configured to automatically prepare one or both ends of an optical fiber in anticipation of one or more subsequent manufacturing processes involving the fiber.

Abstract: The JarCar Ladder presents an effective, safe, sure, way for people to escape buildings of all heights in emergencies by using commonplace materials (concrete, steel bar, wire cables, hooks, rope, wooden seat, etc.) in a unique life-saving manner, requiring no great intellect to use or employ. The newness of the invention is in its revelation of how minor things can work together as a complete unit for major accomplishments under the most dire circumstances when time is “of the essence.

Abstract: A method for forming an occlusive, typically temporary barrier over the entrance of the ear canal of a user. The method comprises the steps of: (a) without entering the ear canal, covering the entrance of the ear canal of the user with a substrate capable of supporting the formation of an occlusive barrier that substantially covers the entrance to the ear canal while preventing the occlusive barrier from entering the ear canal; (b) applying to the substrate a composition capable of forming in situ a occlusive barrier thereon; and (c) allowing the applied composition to form the occlusive barrier on the substrate in a manner such that the occlusive barrier substantially prevents the entry of solid or liquid foreign matter into the ear canal.

Abstract: A process for producing power by displacing water from a tank for operating a hydro-electric apparatus such as a turbine or Pelton wheel. In one embodiment, combustion products from fossil fuels are utilized to displace water from a reservoir or tank. The combustion products are generated by burning a fuel in a gas that contains more than 25% by volume oxygen to generate a hotter flame and less pollutants. If desired, the fuel and gas can be combusted in the reservoir or tank. In another embodiment, differences in pressure can be used to displace water from a reservoir to the hydro-electric apparatus. With these processes, hydro-electric power can be generated at greatly increased efficiencies compared to the prior art.
