  • Patent number: 11997066
    Abstract: A data transmission system and method thereof for edge computing are provided. A terminal mobile station international subscriber directory number (MSISDN) and a terminal IP of a target terminal are obtained with a domain name system (DNS) by a device providing communication services from the data transmission system. After data packets are sent to the data transmission system, if the target terminal is in an idle mode, a paging message is sent by a terminal wake-up module to enable the target terminal to return to a connected mode for communication. Before a connection is established between the data transmission system and the target terminal, downlink data packets can be temporarily stored, and the packets can be sent after the target terminal is in the connected mode. A computer readable medium for executing the data transmission method is also provided.

    Abstract: A neutron-capture therapy system includes a charged particle beam generation unit, a beam transmission unit and a neutron beam generation unit. The charged particle beam generation unit includes an ion source and an accelerator. The accelerator accelerates charged particles generated by the ion source, so as to obtain a charged particle beam of the required energy. The neutron beam generation unit includes a target, a beam shaping body and a collimator. The charged particle beam irradiates onto the target through the beam transmission unit to generate neutrons, which sequentially pass through the beam shaping body and the collimator to form a neutron beam for therapy. The neutron-capture therapy system is accommodated in a concrete building including an irradiation room, an accelerator chamber and a beam transmission chamber. The neutron beam generation unit is at least partially accommodated in a partition wall of the irradiation chamber and the beam transmission chamber.
