Abstract: Exemplified methods and systems facilitate presentation of data derived from measurements of the heart in a non-invasive procedure (e.g., via phase space tomography analysis). In particular, the exemplified methods and systems facilitate presentation of such measurements in a graphical user interface, or “GUI” (e.g., associated with a healthcare provider web portal to be used by physicians, researchers, or patients, and etc.) and/or in a report for diagnosis of heart pathologies and disease. The presentation facilitates a unified and intuitive visualization that includes three-dimensional visualizations and two-dimensional visualizations that are concurrently presented within a single interactive interface and/or report.

Abstract: A hammer union includes a male sub, a threaded female sub, a threaded union nut disposed around abutting ends of the threaded female sub and the male sub, the abutting ends of the threaded female sub and the male sub include contact surfaces perpendicular to a longitudinal axis of the hammer union, and an outermost diameter of the perpendicular contact surfaces and a minor thread diameter of the female sub are equidistant from a longitudinal axis of the hammer union. A method of assembling a hammer union includes inserting a plurality of load segments between a threaded union nut and a male sub, threadedly engaging internal threads of the threaded union nut with external threads of a female sub, and engaging flat contact surfaces of abutting ends of the male sub and the female sub.

Abstract: A union connection common in connecting pipelines in various industries comprises a threaded female pipe end, a male pipe end insertable into the female pipe end to form a sealed connection, a plurality of shaped ring segments and a threaded collar in which the shaped ring segments are placed in a shaped groove on the male pipe and positioned in the threaded collar. The threaded female pipe end is then threaded onto the threaded collar, the threads each being clocked so as to press the collar against the male pipe using the ring segments and into a sealed connection with the female pipe. A pin inserted through a pin hole in the collar and into a pin recess in the female pipe end holds the parts in place. The pin hole and pin recess are positioned relative to the clocked threads of the collar and female pipe.

Abstract: The invention comprises a flapper check valve assembly in which a flapper coated with an elastomeric seal is pivotably attached to a swing arm, and further in which the swing arm is pivotably attached to a retainer ring permitting two degrees of freedom of motion. The retainer ring is mounted in a check valve body. A novel mounting of the flapper to the swing arm ensures the flapper seals the pipeline against backflow.

Abstract: The present disclosure is directed to a system for sensor-based objective determination. In general, sensor data may be used to render objective determinations that were not previously possible due to the unavoidable subjectivity of human-based officiating systems. For example, at least one device may be configured to make objective determinations during the course of a sporting event. Data collection circuitry may receive data from sensor devices coupled to players, equipment, playing surfaces, etc. Data analysis circuitry may categorize the data and input the data into a model to determine if an infraction occurred. For example, categorization may involve determining a type of infraction that may have occurred based on the sensor data. The model may then be selected based on the type of infraction, the model being developed utilizing prior sensor data, rules for the sporting event, etc. Output circuitry may generate a notification based on the infraction determination.

Abstract: A method and apparatus of additive manufacturing is provided, along with a 3D printed product, in which 3D printing is implemented axially, according to a cylindrical coordinate system based on the cylindrical axis of shaft. A shaft is provided as a build base. A layer of additive material is deposited onto the surface of the shaft in rows having axial coordinates in an axial direction of the cylindrical axis. Each of the rows are separated from each other by azimuthal coordinates representing angles of rotation around the cylindrical axis. Radial coordinates are displaced from the cylindrical axis such that subsequent layers are similarly deposited atop radially underlying layers, where the layers are separated by layer thicknesses represented by respective radial coordinates. The shaft is supported by a rotating chuck and an extruder is supported by carriages movable in the axial and radial directions.

Abstract: A pressure relief comprises a valve body which includes an inlet bore that is connectable to a flow line, an outlet bore that is connectable to a vent line and a valve bore that extends to between the inlet and outlet bores. A valve member is slidably supported in the valve bore and is moveable between a closed position in which the fluid in the flow line is prevented from flowing from the inlet bore to the outlet bore and an open position in which the fluid in the flow line is permitted to flow from the inlet bore to the outlet bore. A solenoid operated pilot valve is connected to the valve body over the valve bore, and a fluid chamber is located in the pilot valve above the valve member. The fluid chamber is filled with a hydraulic fluid, and the hydraulic fluid in the fluid chamber is operatively engaged with the valve member.
