  • Publication number: 20210065976
    Abstract: The present invention discloses an inter-layer transition forming machine for winding of a large-sized superconducting coil. A vertically movable forming mechanism and a horizontally movable forming mechanism are mounted on a fixing plate. When the winding of a large-sized superconducting coil performs inter-layer transition, an armored superconducting conductor is clamped by wedge clamping mechanisms with right- and left-handed threads on the vertically movable forming mechanism and the horizontally movable forming mechanism, and a reference line on the conductor is ensured to be aligned with a reference line on a forming mold. The vertically movable forming mechanism is pressed down, under the drive of a double-acting hydraulic cylinder, in a vertical direction to form inter-layer transition, and the horizontally movable forming mechanism moves in a horizontal direction according to the reduction of the vertically movable forming mechanism.

    Abstract: A deposition system for winding of a large-scale superconducting magnet coil. First and second conductor supports withstand the weight of a bent conductor and allow the conductor to be lowered down in spiral and be placed smoothly onto a rotary table. The rotary table bears the weight of coils, rotates according to a contour of the coil and forwarding speed of the conductor, and tracks the winding trajectory of the coil accurately, which avoids the extra stress induced onto the conductor. The conductor placed on the rotary table is reliably clamped by clamping fixtures and adjustable rod to ensure the conductors to be placed on correct radial and toroidal positions. After treated by the deposition system, the conductor is placed to a corresponding position on the rotary table smoothly and accurately to achieve a high-precision contour control of the coil.

  • Patent number: 10873885
    Abstract: A wireless communication system may support two types of networks, such as a 4th-Generation (4G) network and a 5th-Generation (5G) network. The 4G network is accessed through Long-Term Evolution (LTE) base stations. The 5G network is accessed through New Radio (NR) base stations. During idle mode, a communication device may scan 5G RF frequencies to determine whether a 5G signal is available and whether to display a 5G network symbol in the status bar of the device. The communication device is configured to detect conditions indicating whether a user of the device is likely viewing the device and/or the display of the device. If it is unlikely that the user is viewing the device or its screen, RF frequency scanning is paused to reduce power consumption and the currently displayed network symbol is maintained until RF frequency scanning is resumed.

  • Patent number: 10728946
    Abstract: A cellular communication network may be configured to use a primary Long-Term Evolution (LTE) base station and a secondary New Radio (NR) base station to implement a Non-Standalone Architecture (NSA) configuration. The primary LTE base station broadcasts system information, for reception by the communication device, using System Information Blocks (SIBs). The secondary NR base station, however, may be configured to not broadcast certain system information. Rather, system information of the NR base station is specified to the communication device in communications from the LTE base station during setup of an NR data connection. When there is a change in the system information of the NR base station, the network is configured to forgo updating the communication device with the new system information at least until the existing NR data connection is terminated.

  • Publication number: 20200196211
    Abstract: When using Dual Connectivity in a Non-Standalone Architecture cellular communication system, a data bearer may be steered through a Long-Term Evolution (LTE) base station or a New Radio (NR) base station. Each bearer is assigned a combination of Quality of Service (QoS) values corresponding to the service type that the bearer is supporting. For example, each different service type may be assigned a combination of a QoS Class Identifier and an Allocation and Retention Priority parameter value. Each combination is also associated with a radio access technology such as LTE radio access technology or NR radio access technology. When NR communications are available between a network core and a communication device, and if the bearer's combination of QoS values has been associated with NR, bearer data is routed through an NR base station. Otherwise, the bearer data is routed through the LTE base station.

  • Patent number: 10687287
    Abstract: A cellular communication device is configured to use Non-Standalone Architecture (NSA) dual connectivity for communicating with a cellular communication network, using simultaneous 4th-Generation (4G) Long-Term Evolution (LTE) and 5th-Generation (5G) New Radio (NR) radio access technologies. When implementing NSA dual connectivity, the device may receive separate transmit power control commands for LTE uplink transmissions and NR uplink transmissions, respectively. In order to keep total transmitted power of the device below a regulatory maximum transmit power, LTE transmit power is limited to a value that is less than regulatory maximum transmit power, thereby reserving at least a reserved transmit power for NR transmissions. This allows NR acknowledgements to be sent from the device to avoid NR downlink failure.

  • Publication number: 20200068468
    Abstract: A first access node of a first wireless access network receives, via a first entry node of the first network, a service-request message from a terminal registered with the first network. The first access node requests first network-capacity information associated with the first wireless access network from the first entry node, and second network-capacity information associated with a second wireless access network from a second access node of the second network. The first access node selects a target access network based on the service-request message and the first and second network-capacity information. The first access node, in response to a selection of the first wireless access network, sends a service-reply message to the first entry node. The first access node, in response to a selection of the second wireless access network, triggers a handover of the terminal to the second wireless access network.
