Publication number: 20240127603Abstract: Provided are a system and methods for a unified framework and tooling for lane boundary annotation, which include obtaining sensor data along a trajectory corresponding to locations of a base map. Features are extracted from the sensor data. The features are input into a trained neural network that outputs overlapping rich feature maps comprising polylines.

Patent number: 10954754Abstract: Assemblies and methods are provided for positioning a sealing tool within a receptacle and pressure testing a seal between the sealing tool and the receptacle. The assembly may be coupled to the sealing tool for latching the sealing tool into the receptacle. The assembly may include a projection that is movable between a coupled position and an uncoupled position. In the coupled position, the projection may couple the assembly to the sealing tool. In the uncoupled position, the projection may be positioned such that the assembly is not coupled to the sealing tool. The projection may move from the coupled position to the uncoupled position in response to determining a seal is established between the sealing tool and the receptacle.Type: GrantFiled: November 14, 2017Date of Patent: March 23, 2021Assignee: Halliburton Energy Services, Inc.Inventors: Matthew Bradley Stokes, Christian Alexander Ramirez, Lester Barett Dupler, Borisa Lajesic
