    • An electrical connector comprising a binding post intended to be fixed to a suitable supporting surface such as the wall of a loudspeaker enclosure, and including an outwardly extending portion provided with a camming surface disposed spirally relative to the axis of the binding post, and an operating cap of dielectric material, desirably having at least slight elastic deformability, and provided with a conductor-receiving bore extending therethrough and disposed eccentrically relative to the axis of the binding post and cap. The lower body portion of the cap has formed therein a downwardly open cavity for partially receiving the operative portions of the binding post, whereby twisting the cap through a limited angle, substantially less than 180.degree., serves to force the bared conductor within the cap into tight conductive relation with the cammed surface of the binding post. The cap is maintained in coaxial relation with the binding post by structure both above and below the cam, including an upper stud of the binding post journaled in a central bore in the upper part of the cap, and by compressional engagement between the lower peripheral skirt of the cap and a slightly elliptical flange on the binding post, immediately beneath the cam.
    • 一种电连接器,包括用于固定到诸如扬声器外壳的壁的合适支撑表面的装订杆,并且包括向外延伸的部分,该部分设置有相对于装订杆的轴线螺旋地设置的凸轮表面,以及操作 电介质材料的盖,期望地具有至少轻微的弹性变形能力,并且设置有延伸穿过其并且相对于接合柱和盖的轴线偏心设置的导体接收孔。 盖的下部主体部分已经形成有向下开口的空腔,用于部分地接收装订杆的操作部分,由此将盖扭转到大约小于180度的有限角度,用于将盖中的裸露导体加强 与装订柱的凸轮表面紧密的导电关系。 盖子通过凸轮上方和下方的结构与装订杆保持同轴的关系,包括装在上盖中的中心孔中的装订杆的上部螺柱,以及下部外围裙部之间的压缩接合 的盖子和一个略微椭圆形的法兰在装订柱上,立即在凸轮下方。

    • A LAN has a wireless portion which includes access points and wireless communications devices and a wired portion which includes such things as routers, servers, and a PBX. The LAN operates in a radio frequency band where certain channels (DFS channels) are shared with a signal that is of higher priority than the communications signals transmitted and received by the access point and the wireless communications devices. If a higher priority signal is sensed on a particular channel of the wireless medium by a master device, it is necessary for all of the slave devices communicating on this channel to stop transmitting on that channel within a short period of time. The wireless communications devices are mobile and can be easily transported around in space or roam during a communications session. While roaming during a communications session, it is likely that the communications device will move out of range of an access point with which it is currently associated and possibly cause the session to end prematurely, and so it is important that a handoff procedure operates so that a communications session is continuous as the communications device roams from access point to access point. By setting and maintaining a timer dedicated to each available DFS channel, it is possible to ensure that the communications sessions is not interrupted during the roaming process in an environment were certain channels are shared with a higher priority signal.
    • LAN具有包括接入点和无线通信设备的无线部分以及包括诸如路由器,服务器和集团电话之类的有线部分。 LAN工作在无线电频段,其中某些信道(DFS信道)与比由接入点和无线通信设备发送和接收的通信信号优先的信号共享。 如果由主设备在无线介质的特定信道上感测到较高优​​先级信号,则在该信道上通信的所有从设备在短时间段内停止在该信道上的传输是必要的。 无线通信设备是移动的,并且可以在通信会话期间容易地在空间中漫游或漫游。 在通信会话期间漫游时,通信设备很可能移动超出其当前关联的接入点的范围,并且可能导致会话过早结束,因此重要的是切换过程操作使得 当通信设备从接入点漫游到接入点时,通信会话是连续的。 通过设置和维护专用于每个可用的DFS信道的定时器,可以确保通信会话在环境中的漫游过程期间不被中断,某些信道与较高优先级信号共享。
