  • Patent number: 11346313
    Abstract: A fuel flow limiter assembly includes a limiter body forming a central bore, and including a shutoff piston within the central bore having a closing hydraulic surface exposed to a fluid pressure of the fuel inlet, and being movable from an open position, to a closed position based on a fuel pressure drop from a fuel inlet to a fuel outlet in the limiter assembly. A fuel filter is resident in the limiter assembly and supported in a connector coupled to the limiter body. The fuel filter is elongate and projects from the connector into a fuel flow path from the fuel inlet to the fuel outlet.

  • Patent number: 11341511
    Abstract: Implementations relate to systems and methods for generating a user profile based on periodic location fixes. A cellular telephone or other mobile device captures location information via GPS or other capability. A location history can be generated from accumulated location fixes. The location history is then analyzed to detect the user's travel and dwell patterns. That information can be combined with business classification (e.g., SIC, etc.) or Point of Interest (POI) databases to identify a user's likely home, work, or other locations based on dwell-times, time of day, and other parameters. The user's age and gender can potentially be inferred based on types of locations visited, such as school locations. The user profile can be correlated with market segmentation databases to generate a marketing rating, such as a Nielsen or Claritas rating. Advertising, media, or other content can then be tailored to the user's individual location and demographic profiles.

  • Publication number: 20220096974
    Abstract: A filtration device includes a guide member and an adjustable ring assembly. The guide member is configured to be secured to an interior of a fuel device and includes a plurality of holes to guide fuel therethrough. The adjustable ring assembly is configured to be positioned within the interior of the fuel device to filter the fuel flowing through the fuel device. The adjustable ring assembly has a plurality of stackable rings that are concentrically aligned. A junction between a first ring and a second ring, of the plurality of stackable rings, defines a plurality of openings that fluidly communicate with the plurality of holes. The plurality of openings are smaller, respectively, than the plurality of holes.

  • Patent number: 11239507
    Abstract: Lead from lead acid battery scrap is recovered in two separate production streams as clean grid lead and as high-purity lead without smelting. In preferred aspects, lead recovery is performed in a continuous process that uses an aqueous electroprocessing solvent and electro-refining. Spent electroprocessing solvent and/or base utilized to treat lead paste from the lead acid battery scrap can be recycled to the recovery process.

  • Publication number: 20210321217
    Abstract: A method for performing contact tracing. An analysis system performing the method receives geo-temporal data comprising location data points for various wireless terminals, including the wireless terminal being used by a person diagnosed as having a specified disease and the wireless terminals of people who possibly have come in contact with the infected person. Based on filtering the geo-temporal data, the analysis system generates relatively-condensed mobility profiles that are representative of each person's locations and movements, and analyzes the mobility profiles. Through careful selections of various parameters based on the disease that is being analyzed, the mobility profiles are used instead of the relatively large amounts of geo-temporal data, to represent users of wireless terminals and to determine their interactions in regard to disease transmission.

  • Publication number: 20210279114
    Abstract: A system monitors an event loop executing on a host and determines causes for delays in tasks of the event loop. The system may include circuitry that receives, from an agent of the host, event loop data defining suspend and resume times of the tasks of the event loop executing on the host. The circuitry determines, based on the event loop data, event loop analysis data defining execution times for each of the tasks. The circuitry determines, based on the event loop analysis data, a cause of a delay in a task of the event loop as resulting from at least one of (i) a task delay in execution of the task or (ii) a loop delay in execution of another task of the event loop.

  • Patent number: 11072864
    Abstract: Lead is recycled from lead paste of lead acid batteries in a process that employs alkaline desulfurization followed by formation of plumbite that is then electrolytically converted to pure lead. Remaining insoluble lead dioxide is removed from the lead plumbite solution and reduced to produce lead oxide that can be fed back to the recovery system. Sulfate is recovered as sodium sulfate, while the so produced lead oxide can be added to lead paste for recovery.
