    • A hand-held device (10) for creating a pressure change in a person's ear canal. It has an interior space forming an air chamber (50), a plunger (58) and a valve means (52) frictionally engaged with said plunger (58), a tube (14) with an earpiece (48), and a finger-actuated diaphragm (60) in an external wall of the air chamber (50). The diaphragm (60) moves the plunger (58) from a resting position, and in a first direction. A spring (56) returns the diaphragm (60) to its undepressed position. Initial movement of the plunger (58) in said first direction from said resting position displaces the valve (52) from a first position to a second position at which the valve means (52) is stopped from further movement in said first direction. Further movement of the plunger (58) in said first direction causes the plunger (58) to slide relative to the valve (52). The device (10) is intended for treatment of Mënière's disease and ear pain from other causes.
    • 一种用于在人的耳道中产生压力变化的手持装置(10)。 它具有形成空气室(50),柱塞(58)和与所述柱塞(58)摩擦接合的阀装置(52)的内部空间,具有耳塞(48)的手指管(14) 在空气室(50)的外壁中的致动隔膜(60)。 隔膜(60)使活塞(58)从静止位置和第一方向移动。 弹簧(56)将隔膜(60)返回到其未受压位置。 柱塞(58)沿着所述第一方向从所述静止位置的初始移动将阀(52)从第一位置移位到第二位置,在该位置处,阀装置(52)停止在所述第一方向上的进一步移动。 柱塞(58)沿所述第一方向的进一步运动使得柱塞(58)相对于阀(52)滑动。 设备(10)旨在用于治疗梅内尔氏病和其他原因引起的耳痛。

    • A Private Network-Network Interface (PNNI) network including interconnected nodes is defined as a single rerouting domain (“global domain”) and the global domain is further defined by multiple divided domains (“local domains”). Each of the local domains is defined to include multiple nodes that are included in the network. Connection recovery and path optimization in the global domain (the entire PNNI network) are performed in accordance with a global rerouting protocol. The global rerouting protocol is a modification of the standard Domain-Based Rerouting (DBR) protocol, by adding information elements of domain identifier, rerouting for the global domain. The DBR protocol does not support the connection recovery from a link failure between local domains (“inter-domains”) and the global path optimization. The global rerouting method is capable of connection recovery and path optimization outside of any rerouting local domains. The global rerouting provides double fault recovery within the rerouting domain (“intra-domain”) as covered by the DBR and outside of the domains (“inter-domain”) or when the initial fault recovery within the domain has failed. Also, the global rerouting method provides maximum path optimization across all domains and within the rerouting local domain.
    • 包括互连节点的私有网络 - 网络接口(PNNI)网络被定义为单个重路由域(“全局域”),并且全局域由多个分割域(“本地域”)进一步定义。 每个本地域被定义为包括在网络中的多个节点。 根据全局重路由协议执行全局域(整个PNNI网络)中的连接恢复和路径优化。 全局重路由协议是通过添加域标识符的信息元素,重新路由到全局域,来修改标准的基于域的重路由(DBR)协议。 DBR协议不支持本地域(“域间”)与全局路径优化之间的链路故障的连接恢复。 全局重路由方法能够在任何重新路由的本地域之外进行连接恢复和路径优化。 全局重新路由在由DBR和域外(“域间”)覆盖的重路由域(“域内”)内或域内的初始故障恢复失败时提供双重故障恢复。 此外,全局重路由方法提供跨所有域和重路由本地域中的最大路径优化。
