    摘要： A method and system for counteracting performance deterioration in an electrochemical fuel cell includes passive re-activation, active re-activation, or both. Active re-activation includes intermittently applying positive voltage electrical pulse across the anode. The positive voltage applied is less than that required for decomposition of water. Passive re-activation includes interposing a resistive load between the anode and the cathode while fuel stream flow to the anode is interrupted. The resistive load increases voltage potential at the anode to less than that required for oxidation of carbon.

    摘要： An improved media server interconnect to subscriber terminals is accomplished with a plurality of media servers at a headend where each media server provides one or more programs for distribution to the subscriber terminals. An array of modulators connects a requested media asset, such as a video program or WEB page, from a media server to a requesting subscriber terminal. A connection manager responds to a media asset request from the requesting subscriber terminal and selects a source server to provide the requested media asset and selects a modulator in the array to send the requested media asset from the source server to the requesting subscriber terminal. The array of modulators acts as a two stage switch between the source server and the requesting subscriber terminal. A selected modulator in said array is the switch point in the two stage switch. The connection manager controls a first stage of the switch by selecting the selected modulator to receive the requested media asset from the source server. The requesting subscriber terminal acts as a second stage of the two stage switch also under the control of the connection manager by tuning to the channel frequency of the selected modulator.

    摘要翻译： 与用户终端的改进的媒体服务器互连通过在前端的多个媒体服务器完成，其中每个媒体服务器提供一个或多个节目以分发给用户终端。 调制器阵列将所请求的媒体资源（例如视频节目或WEB页面）从媒体服务器连接到请求用户终端。 连接管理器响应来自请求用户终端的媒体资产请求，并且选择源服务器以提供所请求的媒体资产，并选择阵列中的调制器以将所请求的媒体资产从源服务器发送到请求用户终端。 调制器阵列用作源服务器和请求用户终端之间的两级交换机。 所述阵列中选择的调制器是两级开关中的开关点。 连接管理器通过选择所选择的调制器来控制交换机的第一级，以从源服务器接收所请求的媒体资产。 请求用户终端也在连接管理器的控制下，通过调谐到所选择的调制器的信道频率，起到两级交换机的第二级的作用。
