    • It provides a surge arrester (1) and its manufacturing method. The surge arrestor (1) includes an active part (10) extending along a longitudinal direction (14) of the surge arrester (1), a first electrode (11) having a first interlocking part (110), being arranged to rest against a first end (100) of the active part (10), a second electrode (12) resting against a second end (101) of the active part (10), wherein the second end (101) opposes the first end (100) in the longitudinal direction (14) of the surge arrester (1), a flexible insulating housing (13), being arranged around an assembly of the first electrode (11), the active part (10) and the second electrode (12), and a second interlocking part (132) formed on an inner surface of the flexible insulating housing (13). The first interlocking part (110) of the first electrode (11) is arranged to fit with the second interlocking part (132) of the flexible insulating housing (13) for preventing relative movement of the first electrode (11) and the flexible insulating housing (13) in the longitudinal direction (14) of the surge arrester (1). The flexible insulating housing (13) includes: a support member (130) mechanically connecting and supporting the assembly of the first electrode (11), the active part (10) and the second electrode (12), which has a plurality of supporting elements (130a,130b) being arranged parallel to the longitudinal direction (14) of the surge arrester (1) and being arranged laterally at sides of the assembly of the first electrode (11), the active part (10) and the second electrode (12), and an insulating expandable part (131) with a plurality of sheds extending outwards, being moulded around the support member (130) and being spaced apart from the assembly of the first electrode (11), the active part (10) and the second electrode (12). Because the support elements (130a,130b) are mechanically connected by the flexible insulating housing (13), by exerting outwards radial force on the flexible insulating housing (13), the cross- section of its inner space is enlarged, thus making it easier to insert the assembly of the first electrode (11), the active part (10) and the second electrode (12) into the flexible insulating housing (13). Besides, the interlocking mechanism ay prevent an undesirable relative movement between the electrode (11,12) and the flexible insulating housing (13) in the longitudinal direction (14).

    • Cognitive radio with the intelligent capabilities of opportunistic spectrum access has been proposed as an enabling element of next generation digital communications. However, the methods of wireless traffic prioritization under cognitive radio systems are missing in prior arts. The invention therefore discloses such traffic prioritization methods which can be applied in diverse cognitive radio implementations. The disclosed methods in principle enforce lower interference probabilities over higher- priority traffics. The spectrum sensing policies are then designed in such a way that higher-priority traffics are associated with clearer spectrum assessments. Moreover, the disclosed methods do not exert any additional communication overhead, so as to maximize the implementation efficiency; and are compatible with the prior arts of traffic prioritization in conventional communication systems. Numerous embodiments are elaborated in the disclosure without deviating from the design principle.
    • 具有机会性频谱接入的智能能力的认知无线电被提出作为下一代数字通信的一个启发元素。 然而,在现有技术中缺少认知无线电系统下的无线流量优先级的方法。 因此,本发明公开了可应用于不同认知无线电实现的这种业务优先级方法。 所公开的方法原则上在较高优先级业务上实施较低的干扰概率。 然后,频谱感应策略的设计使得更高优先级的业务与更清晰的频谱评估相关联。 此外,所公开的方法不会发挥任何额外的通信开销,从而最大化实现效率; 并且与常规通信系统中的流量优先级的现有技术兼容。 在不脱离设计原理的情况下,本公开中阐述了许多实施例。
