  • Patent number: 11907069
    Abstract: In network devices, during manufacturing, input for designation of a region code to be a non-specific region code is stored in a BIOS memory of the network device, and a specific region code is stored off the BIOS. During boot up, the BIOS is checked for a specific region code to regulate wireless transmissions at a physical location of operation. Responsive to receiving the non-specific region code from BIOS, the specific region code is requested from a region code server based on a network device identifier. Once received, the region code is stored in flash memory, until rebooted or otherwise reset, rather than BIOS.

  • Patent number: 11780149
    Abstract: The present disclosure provides a winding device for producing a fiber composite loop chain and a winding method, and belongs to the field of production equipment. The problem that an existing composite loop chain forming technology has tension defects is solved. The winding device includes a main shaft assembly, a clamp pushing-in mechanism, travel switch assemblies, a mold pushing mechanism, a clamp pulling-out mechanism, a positioning and clamping mechanism and a tension control mechanism which are fixedly connected to a rack. The main shaft assembly includes a driving mechanism, a bearing pedestal, a rotating main shaft, clamp sliding shafts and a supporting block. The driving mechanism is connected with one end of the rotating main shaft, and the other end of the rotating main shaft is connected with the supporting block. The rotating main shaft is connected with the bearing pedestal through a bearing, and the bearing pedestal is fixed to the rack. Two clamp sliding shafts are provided.

  • Patent number: 11151422
    Abstract: Empty container identification method and system are disclosed. The method includes: obtaining customs declaration information, and finding out an vehicle declared as an empty container or an empty vehicle from the customs declaration information; performing X-ray inspection on the vehicle to acquire a transmission image of the vehicle; inputting the transmission image into an empty container identification model obtained by pre-training, so that the empty container identification model determines candidate regions of the transmission image, and performs post-processing analysis on the candidate regions to obtain an image identification result; and comparing the image identification result with the corresponding customs declaration information to determine whether or not the image identification result is consistent with the customs declaration information.

  • Patent number: 6888825
    Abstract: A method and apparatus for sharing storage in a cross-connect. According to one embodiment of the invention, a cross-connect includes a number of sets of data input lines and a number of matrices. Each of the sets of data input lines is to be coupled to a different line card. Each of the matrices is coupled to every one of the sets of data input lines. In addition, each of the matrices has a set of data output lines, where the set of data input lines of each of the matrices is to be coupled to a different one of the line cards.
