Abstract: Disclosed are a method and an apparatus for multi-round alignment of gas long-distance pipeline magnetic flux leakage internal inspection data. The method includes: identifying the primary feature point data of two sets of internal inspection data, dividing the pipeline into multiple primary pipeline sections, identifying the secondary feature points in the primary pipeline sections, aligning the secondary feature points using a segment splitting algorithm, re-aligning unaligned secondary feature points, and aligning remaining feature points and defects in the secondary pipeline sections.

Abstract: A surgical instrument is disclosed herein. The surgical instrument can include an end effector that includes jaws configured to transition between an opened condition and a closed condition, a plurality of electrodes positioned within the jaws of the end effector, a control circuit, and a memory configured to store an algorithm configured to cause the control circuit to determine an impedance signal based on signals received from the plurality of electrodes, detect a media positioned between the jaws of the end effector based on the determined impedance signal, determine a position of the detected media based on the received signals, and generate an alert associated with the detected media and the determined position.

Abstract: A data processing method for a log structured merge (LSM) tree includes selecting SST files to be compressed and merged in a current layer and a next layer, sequentially reading the SST files to be compressed and merged in the current layer and the next layer from a first storage device and sequentially writing the SST files in a second storage device, randomly reading the SST files to be compressed and merged from the second storage device into a memory according to key sequence numbers of data blocks included in the SST files to be compressed and merged, and performing compression and merge processing on the SST files to be compressed and merged. Sequential and random read and write speed of the second storage device is higher than that of the first storage device.

Abstract: A cluster transfer robot includes a body, two clamping arms arranged at the bottom of the body, and a first driving mechanism arranged at the bottom of the body. The first driving mechanism includes a driving wheel configured for driving the transfer robot to move. The clamping arm includes a second driving mechanism and a rotating assembly connected to the second driving mechanism, the rotating assembly includes a rotating arm rotatably connected to the body and a supporting wheel arranged on the rotating arm for supporting the transfer robot, the rotating arm is provided with a clamping portion for clamping automobile tire, and two clamping portions of two rotating arms are arranged facing to each other to define a clamping space for the automobile tire when the two clamping portions are close to each other. The cluster transfer robot can greatly reduce the construction cost of intelligent parking lots.

Abstract: A refrigerator, comprising an automatic door-opening/closing apparatus mounted on a refrigerator body for driving the opening and closing of a door. When opening the door, if a first obstacle detecting apparatus detects the presence of an obstacle in front of the door, then the automatic door opening/closing apparatus stops the opening of the door; when closing the door, if a second obstacle detection apparatus detects the presence of an obstacle behind the door, then the automatic door-opening/closing apparatus stops the closing of the door. This stops the movement of the door upon the discovery of an obstacle while opening or closing the door, thus preventing the door from being damaged by collision, and when the obstacle is a person, preventing physical injuries from being caused.

Abstract: The present disclosure relates to a dump truck, and belongs to the technical field of means of transport. The dump truck includes a chassis frame, a truck bed and rotating frames, where first hinge points exist between the rotating frames and the chassis frame, second hinge points exist between the rotating frames and the truck bed, in a flipping and dumping process of the truck bed relative to the chassis frame, the truck bed can sequentially flip around the first hinge points and the second hinge points, in a flipping process of the truck bed, the truck bed can flip to different states by using a small force depending on dumping completeness of materials, so as to completely dump the materials, a structure is novel, and flexibility is high.
