  • Patent number: 10790586
    Abstract: A feed network, steering apparatus and system for a steerable antenna array are described. The feed network includes a waveguide assembly including first and second radial transverse electromagnetic (TEM) waveguides, and first and second variable phase shifters positioned in the respective TEM waveguides. The variable phase shifters cause additional progressive electrical phase shifts in respective rings of radiating elements, directly proportional to the angular position of the radiating elements in the ring, from 0 to a controllable integer multiple of 2? radians. The feed network includes first and second phase-mode feed probes coupled to the respective radial TEM waveguides, which provide respective phase-mode feed ports. When the feed network is coupled to the antenna array, two consecutive-order phase modes are provided at the phase-mode feed ports. The orders of the phase modes are selectable using a phase shift control signal controlling the integer multiple of the variable phase shifters.

  • Patent number: 10789138
    Abstract: In a method for processing a server message block (SMB) service fault, a first storage device generates a file handle according to a first file open instruction from a host, and sends the file handle to a second storage device. The second storage device stores the file handle as a backup handle. The second storage device activates an Internet Protocol (IP) address of the first storage device according to fault information from the first storage device, and establishes a communication connection to the host. After the second storage device determines a file handle matches the handle identifier, the second storage device opens a file. Hence, when a storage device that processes an SMB service is faulty, the SMB service may be taken over by a secondary storage device such that the SMB service is executed without interruption.
