Abstract: The present invention relates to construction machinery, and relates in particular to an operation device of a skid-steer loader, and a skid-steer loader. The operation device of a skid-steer loader can be disposed on a frame structure (3) of the skid-steer loader, and is located on a side of an operator cab (5) of the skid-steer loader. The operation device comprises a lift arm (16) comprising a clearance section (10). When the lift arm (16) is in a traveling position, the clearance section (10) is located in a region of the lift arm (16) adjacent to a side window of the operator cab. A top portion of the clearance section (10) is recessed toward a bottom portion of the frame structure (3) of the skid-steer loader. The operation device of the skid-steer loader can reduce the area on the side of the operator cab blocked by the lift arm, thereby increasing the peripheral vision of a driver.

Abstract: A Block-Type structured diamond grinding wheel with adaptive supply of instantaneous Cooling, includes a grinding wheel substrate and several grinding wheel units, each including an execution mechanism, a push mechanism, and an instantaneous Cooling mechanism. Various structured patterns are provided on an upper surface of the grinding unit in the execution mechanism, and a heat sink is disposed at a lower surface. During operation, a tangential grinding force generated by the grinding unit and a workpiece presses a sprayer to spray nano fluid into an operating region, to implement instantaneous Cooling of grinding wheel. When wear occurs in a grinding unit of a grinding wheel, a corresponding grinding unit may be replaced to extend the service life of the grinding wheel, and production costs are reduced. A special surface structure of the grinding unit further enhances a cooling effect, thereby improving a surface quality of a workpiece.

Abstract: Provided are a decoding method, a decoding device and a decoder. The method includes: setting a decoder parallelism P, and splitting soft information of a block to be decoded according to the parallelism P; performing decoding calculation on the block to be decoded according to the split information, and outputting decoded hard bit information; and recombining the hard bit information according to the parallelism P.

Abstract: Provided are a positioning method, apparatus and system, a layout method for a positioning system and a storage medium. A plurality of labels is laid with preset positioning precision in an area to be positioned, where each label among the plurality of labels carries label information, where the label information corresponds to position information of a position of the each label. A position acquisition device reads first label information on a label at a distance not greater than the preset positioning precision from the position acquisition device; and the position acquisition device determines first position information of the position acquisition device according to the first label information.
