Abstract: An apparatus and method for preparing high-purity spherical magnesium and/or high-purity magnesium powder are provided. The apparatus includes a vertical furnace body, a heating zone, and a condensing zone, where a periphery of the condensing zone is provided with a first thermal insulation device and a second thermal insulation device sequentially from bottom to top, and each of the first thermal insulation device and the second thermal insulation device is removably arranged; the periphery of the condensing zone is further provided with a liquid cooling device; a gas inlet and a gas outlet are formed in the condensing zone; and an inner wall of the condensing zone is provided with an arrangement structure configured to arrange a collection device. A heating temperature of a material and condensation conditions in the condensing zone are controlled to make an evaporated magnesium vapor condensed on the collection device in the condensing zone.

Abstract: A battery and a manufacturing method thereof are disclosed. The battery includes at least one battery cell and at least one switching element; each of the at least one switching element is respectively connected to one or more of the at least one battery cell to control the one or more of the at least one battery cell.

Abstract: In one embodiment, a packet switching device is configured to operate as a spoke or a hub in a Dynamic Multipoint Virtual Private Network (DMVPN) using one or more initially negotiated service overlay capabilities including service encapsulation to use in communicating service overlay data packets between the packet switching device and another device (e.g., spoke, hub) of the DMVPN over an established tunnel (e.g., secure protocol channel). The packet switching device is further configured to negotiate updated one or more service overlay capabilities including updated service encapsulation to use in communicating service overlay data packets with another device (e.g., spoke, hub) without dropping the already established tunnel. In one embodiment, the negotiation between the packet switching device and another device (e.g., spoke, hub) of the DMVPN uses Next Hop Resolution Protocol (NHRP). In one embodiment, the service encapsulation uses Network Service Header (NSH).

Abstract: According to one aspect, a control entity (such as a policy server) in communication with a plurality of border routers in a network, generates failover entries for one or more traffic flows. Each failover entry specifies a backup path to be used by a border router when the border router determines that a wide area network interface of the border router has failed. The control entity sends the failover entries to each of the border routers. A border router operating in a network stores failover entries for one or more traffic flows. For packets received at the border router either from a local area network interface or via a tunnel from another border router, when the border router detects that the wide area network interface has failed, the border router determines how to handle the packets based on the stored failover entries.

Abstract: A method of manufacturing anti-bacteria polyamide fiber via high speed spinning disclosed a kind of method, which can make manufacturing anti-bacteria polyamide fiber via high-speed spinning realized, including the preparation of anti-bacteria particles and process of high-speed spinning. The preparation of anti-bacteria particles includes surface treatment of anti-bacteria agent and its process of preparation. Choose nano zeolite carrying silver ion as anti-bacteria agent, mix the anti-bacteria particles and polymer chips, after melting, produce anti-bacteria yarns via high speed spinning. The surface treatment to the anti-bacteria agent the invention can improve the spinnability of raw material and place foundation for realizing high speed spinning.
