Abstract: Architectures and techniques are for significantly improving operation of unmanned underwater vehicles (UUVs). For example, a UUV can have modular interfaces that can be configured to interchangeably connect different types of sensors to facilitate different UUV applications, to interchangeably connect different types of clamping devices that can be configured for different types or sizes of underwater pipe, and can comprise a mother ship interface that can be used to exchange information and supply a fluid for the clamping device. The UUV can comprise a PID controller that can be used for autonomous navigation to a target location of the underwater pipe and autonomous coupling, via the clamping device, to the underwater pipe.

Abstract: The present disclosure provides an array substrate, a display panel and a display device. The array substrate includes a base substrate and a thin film transistor. An orthographic projection of a drain of the thin film transistor on the base substrate does not go beyond an orthographic projection of a gate of the thin film transistor on the base substrate.

Abstract: A method for repairing a display defect includes: detecting the display defect in a display panel; and repairing a partial structure of the display defect so that a size of a remaining structure of the display defect is smaller than a test standard value.

Abstract: A display substrate and a display device including the display substrate are provided. The display substrate includes an alignment mark in an alignment region of the display substrate; and a blocking structure in a preset region around the alignment mark, wherein the blocking structure is arranged to block residual particles carried by a rubbing roller during rubbing.
