  • Publication number: 20250092918
    Abstract: Drivetrains and constant velocity joints for recreational vehicles are disclosed. These joints comprise a housing, an aperture for connecting with an axle, and interior components for rotatably connecting the axle to the housing. Various retention mechanisms improve the retention of constant velocity joints, including hydraulic-based, disc-based, pin-based, spline-based, and spring ring-based mechanisms. Hydraulic-based systems utilize adjustable hydraulic pressure for maintaining engagement. Disc-based mechanisms employ a conical disc that provides additional frictional force to resist pull-out forces. Pin-based retention involves drive pads or pins and corresponding tracks or grooves in the shaft interfacing gear. Spline-based mechanisms include a toolless locking half shaft retention system with rotating, interrupted splines. Spring ring-based retention features multiple flexible retaining rings placed axially along the spline, providing improved shaft retention.

  • Patent number: 12110761
    Abstract: A plug for use in a wellbore has a piston that is movable on a body. A control valve is disposed in communication between the wellbore and a piston chamber and can capture wellbore pressure in the piston chamber. A closure on the body can transition from a closed condition to an open condition relative to the port in response to the movement of the piston. A fixture releasably holds the closure in the closed condition on the body. The fixture releases in response an increased pressure differential on the piston above an initial pressure differential between the captured chamber pressure and the wellbore pressure.

  • Publication number: 20230399939
    Abstract: A downhole sensor apparatus may include a first surface at a first end of the downhole sensor apparatus, a sensor coupled to the downhole sensor apparatus, and an exterior surface at a second, opposite end of the downhole sensor apparatus. The downhole sensor apparatus is configured to be inserted into a recess of a drill string component such that the first surface is adjacent an interior surface within the recess. The exterior surface of the downhole sensor apparatus is configured to receive external pressure that results in a force that transfers through the downhole sensor apparatus to an interface defined by a contact area between the first surface and the interior surface. The contact area of the interface is smaller than the exterior surface. Drill string components, such as earth-boring and downhole tools, incorporating such a downhole sensor apparatus and methods of using same are also disclosed.

  • Patent number: 11822603
    Abstract: Systems and methods for modeling higher-level metrics from graph data derived from already-collected but not yet connected data are disclosed. A method includes extracting a first set of actor-related data, a second set of object-related data, and a third set of temporal data from the set of the already-collected but not yet connected data representative of a unit-level contribution to the target activity. The method further includes generating graph data for a graph using the set of the already-collected but not yet connected data, where each of the plurality of nodes of the graph corresponds to the actor or the object, and where an attribute associated with each of the plurality of edges of the graph corresponds to a measurement associated with the target activity. The method further includes modeling a relationship between graph attributes associated with the graph data and a higher-level metric associated with the target activity.
