  • Publication number: 20180195360
    Abstract: A fracturing system includes a fracturing spool that mounts onto a wellhead assembly for injecting fracturing fluid into a well beneath the wellhead assembly. The fracturing system includes an isolation sleeve and fracturing spool. The isolation sleeve inserts in an axial bore of the fracturing spool, and has a lower end that extends into the wellhead to isolate and protect portions of the wellhead assembly from the fracturing fluid. A groove in an inner surface of the fracturing spool receives an annular seal for sealing between the isolation sleeve and fracturing spool. Injecting a viscous fluid into the groove energizes the seal, and blocks high pressure fracturing fluid from flowing between the isolation sleeve and fracturing spool.

  • Patent number: 10018130
    Abstract: Fuel injector wear compensation methodologies for use with internal combustion engines that alter the injection schedule over the life of the fuel injector(s) by using methods that conduct a primary injection of fuel in the engine (primary fuel event), per an injection schedule within an engine cycle; compare a measured engine parameter(s) to a reference value(s); and then alter the injection schedule applied to the engine, based on the comparing. Another method comprises: during injection events, inject a first fuel in a combustion chamber of the engine; measure an engine parameter(s) of the engine during operation; compare the engine parameter(s) to a reference value(s); add a post injection event of a second fuel during the injection events, based on the comparison. The methods can be applied with single or dual fuels.

  • Patent number: 10019612
    Abstract: A system and method to detect an event associated with a first object relative to a second object and a support is provided. The system can include an antenna at a support to receive the first object, a tag reader in communication with the antenna and a tag located on the second object. In response to detecting a change in impedance of the antenna associated with the presence of the first object, the tag reader communicates a presence signal. In response to detecting the tag within a threshold proximity of the tag reader, the tag reader generates a tag signal. A remoter server is operable to detect an association of the first and second objects based on a comparison a time associated with each of the tag signal and the presence signal, and in response then creates an output indicative of a detected event based on the association for illustration.

  • Patent number: 10019796
    Abstract: Disclosed are novel computer-implemented methods for creating a blood vessel map of a biological tissue. The methods comprise the steps of, accessing image data corresponding to multi-channel multiplexed image of a fluorescently stained biological tissue manifesting expression levels of a primary marker and at least one auxiliary marker of blood vasculature, and extracting features of blood vessels using the primary marker as an input to create a single channel segmentation of the blood vessels. The method further comprises the steps of extracting features of blood vessels using the auxiliary marker to create auxiliary channels as a second input and apply multi-channel blood vessel enhancement. Blood vessel maps are created using the features and tracing the blood vasculature by iteratively extending the centerlines of the initial segmentation using statistical models and geometric rules.

  • Patent number: 10018493
    Abstract: A flow sensor circuit for a fluid flowpath having a self-heated thermistor situated in a fluid flowpath. The flow sensor circuit is configured to energize the thermistor sufficiently to heat the thermistor, calculate the slope of the leading edge of the rise in temperature of the thermistor when the thermistor is energized, and equate the slope to the state of the fluid flowing through the fluid flowpath. In another embodiment, the flow sensor circuit is configured to energize the thermistor, measure and calculate the average and standard deviation of the thermistor temperature, and determine the state of the flowpath using the thermistor temperature average and standard deviation.

  • Patent number: 10021393
    Abstract: An entropy decoder is configured to, for horizontal and vertical components of motion vector differences, derive a truncated unary code from the data stream using context-adaptive binary entropy decoding with exactly one context per bin position of the truncated unary code, which is common for horizontal and vertical components of the motion vector differences, and an Exp-Golomb code using a constant equi-probability bypass mode to obtain the binarizations of the motion vector differences. A desymbolizer is configured to debinarize the binarizations of the motion vector difference syntax elements to obtain integer values of the horizontal and vertical components of the motion vector differences. A reconstructor is configured to reconstruct a video based on the integer values of the horizontal and vertical components of the motion vector differences.
