  • Publication number: 20240114348
    Abstract: Embodiments described herein include methods, systems, and apparatuses for allowing a user equipment (UE) that supports dynamic spectrum sharing (DSS) with uplink (UL)-shift to access a cell and barring UEs that do not support DSS with UL-shift. Embodiments may use a cell barring field in a master information block and additional filters to indicate a barring state for a network node.

  • Patent number: 11949681
    Abstract: Methods and systems are provided for improving user authentication and access control by a network file system service in a multi-tenant public cloud environment by receiving a request for a connection to a file system from a file system client (client), sending an identification request for identification authentication of the client to a control system, receiving a response from the control system, establishing the connection to the file system upon determining that the connection to the file system is allowed based on cloud tenant information associated with the client, receiving an attempt to access the file system from the client by a sub-user, authenticating the sub-user based on the cloud tenant information, issuing a security token including a globally unique sub-user identifier of the sub-user, and using the security token to determine access rights of the sub-user to the file system for a subsequent request.

  • Patent number: 11938466
    Abstract: Embodiments of catalyst systems and methods of synthesizing catalyst systems are provided. The catalyst system may include a core comprising a zeolite; and a shell comprising a microporous fibrous silica. The shell may be in direct contact with at least a majority of an outer surface of the core. The catalyst system may have a Si/Al molar ratio greater than 5. At least a portion of the shell may have a thickness of from 50 nanometers (nm) to 360 nm.

  • Publication number: 20230012762
    Abstract: A terminal and a central electrical box are disclosed. The terminal is used to be mounted on a circuit board. The terminal comprises: a first termination part; a second termination part; and a bending part connected between the first termination part and the second termination part. The bending part is bent by a predetermined angle relative to the first termination part and the second termination part, so that the first termination part and the second termination part are staggered by a predetermined distance along a direction transverse to a direction of inserting the terminal to the circuit board. When the terminal is mounted on the circuit board, one of the first termination part and the second termination part passes through the circuit board. In the present invention, the terminal passes through the circuit board, so that two electronic devices located on both sides of the circuit board can be directly electrically connected through the terminal.

  • Publication number: 20220326345
    Abstract: This application provides example detection signal transmitting methods, detection apparatuses, and storage medium. One example method includes determining an orientation of a field of view of a detection apparatus. One of a plurality of anti-interference parameters can then be selected as a target anti-interference parameter based on the orientation of the field of view of the detection apparatus and according to a predefined rule, where the plurality of anti-interference parameters are determined according to the predefined rule. A detection signal can then be transmitted based on the target anti-interference parameter.
