  • Publication number: 20200233012
    Abstract: An apparatus and method for measuring a structural angular acceleration based on dynamic centrifugal force measurement belong to the technical field of angular acceleration measurement. The apparatus has a solid ball. The solid ball can move freely along the radial direction of the outer wall packaging hood. The elastic block is used as a stress base. A rod for lateral limit and connection is used for connecting the rigid block and a pulley and limiting the displacement of solid ball so that the solid ball can only move longitudinally along the apparatus. The rigid block can move freely due to the pulley. Measurement of a transient angular acceleration is converted into dynamic measurement of the centrifugal force of the solid ball. Through the above design, the dynamic angular acceleration of the structure caused by dynamic load can be relatively accurately calculated.

  • Patent number: 10674416
    Abstract: Embodiments provide a user equipment (UE) device that includes a processor and a transceiver. The processor is configured to direct a handover request to an evolved packet core (EPC) access node via the transceiver. The access node may be, e.g. a wireless local area network (WLAN) access point or an E-UTRAN access point. The handover request may initiate a transfer of connectivity of the UE device from the WLAN access point to the E-UTRAN access point, or from the E-UTRAN access point to the WLAN access point. The processor is configured to receive a handover response from the current access node, wherein the response includes a cryptographic key identifier, and to derive a handover key from the key identifier. The processor may then operate the UE device to provide connectivity based on the handover key between the UE device and the other of the access nodes.

  • Patent number: 9794831
    Abstract: The present invention provides a method for shortening signaling delay of ISC session transfer procedure, a network element for controlling ISC session transfer, a network element for anchoring a media path in ISC session transfer and a communication system including at least two terminals and the above two network elements. In the present invention, the SCC AS decides if a media path needs to be anchored in a media anchor point MRF, and if yes, then instructs a MRF to assign respective media endpoints for a local UE and a remote UE and connect the two media endpoints together, so as to divide the session between the local UE and the remote UE into two independent sub-sessions: a session between the local UE and the MRF, and a session between the remote UE and the MRF. For these two sub-sessions, the SIP signaling is terminated and sent out in the SCC AS. Thus, when a local UE or a remote UE triggers handover, only one sub-session needs to be updated/influenced.
