摘要： A method of managing node resets in a cluster is provided. Status information from a node cluster including a plurality of nodes may be received. A determination of whether a time delay associated with a first node of the cluster is greater than a node reset time may be made based at least on the received status information. The node reset time may comprise a time after which a node reset is automatically triggered. If the time delay associated with the first node is greater than the node reset time, the node reset time may be dynamically adjusted such that a node reset of the first node is not automatically triggered.

摘要： Hybrid fiber/coax networks employ the existing cable plant used for cable TV and transmit data signals in a frequency bandwidth above that which is used for cable TV. As this cable plant was deployed in a tree and branch topology, data transmissions may be susceptible to noise, variable transmission loss and frequency dispersion, particularly in the upstream direction. Further, due to the tree and branch topology, homes at the far end of the network experience much greater loss than do the homes that are near to the headend/ONU. The present system, which uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals, or messages, are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. Messages indicative of an end user routing ID (RID) are identified and the information extracted for user with successive messages. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.
摘要翻译：混合光纤/同轴电缆网络采用用于有线电视的现有电缆设备，并以高于用于有线电视的频率带宽传输数据信号。由于该电缆厂部署在树型和分支拓扑结构中，数据传输可能会受到噪声，可变传输损耗和频率分散的影响，特别是在上行方向。此外，由于树和分支拓扑，网络远端的家庭比靠近头端/ ONU的家庭遭受更大的损失。该系统使用位于馈线/分配网络中的智能网络元件之间的点对点数据链路来提供可靠，安全的双向宽带接入。数字信号或消息在智能网络元件处被终止，被切换和重新生成，以便在将家庭连接到头端或路由器所需的附加上游或下游数据链路上传输。识别指示最终用户路由ID（RID）的消息，并且为具有连续消息的用户提取信息。以这种方式，数据链路通过相对较短的同轴电缆运行进行，这可以提供比归属和前端或光网络单元之间的典型端到端馈线/分配连接更大的带宽。

摘要： A charge sharing suppression circuit for a charge pump circuit in a phase locked loop is disclosed that is capable of suppressing charge sharing due to static phase error in the phase locked loop. A return path is provided to allow charge pump currents to flow when static phase error exists. A first switch in the return path closes in response to an UP signal from a phase frequency detector and a second switch closes in response to an inverted version of a DN signal. A third switch in the return path closes in response to an inverted version of an UP signal and a fourth switch closes in response to a DN signal. The return path is disabled in the absence of static phase error.

摘要： A process for producing a purified gaseous product from a gaseous feedstream such as air containing impurities is disclosed. The impurities such as hydrogen, water vapor, carbon monoxide and carbon dioxide are removed from the gaseous feedstream in a vessel having layers of adsorbents and oxidation catalysts. The placement of the hydrogen to water vapor conversion catalyst downstream of the step of contacting the feedstream with a catalyst to convert the carbon monoxide to the carbon dioxide and the step of removing the carbon dioxide from the feedstream improves not only performance but also the economies of the purification system.

摘要： The present invention provides for a process for purifying atmospheric air prior to its separation by cryogenic distillation. The process utilizes three adsorbent layers, the first primarily removes water; the second primarily removes CO2; and the third layer is designed to remove displaced gas components such as N2O and hydrocarbons which are displaced by the second layer. It has been found that CaX type adsorbents provide the removal of N2O and hydrocarbons in the third layer.

摘要： A profile service, instance is linked to a plurality of external data stores. Each external data store is associated with a predefined data store connector class that describes a connector object that establishes a link and provides methods to query the associated data store. An external data store profile is created in the profile service that names the connector class. An external data store reference object is created in the profile service instance that identifies the external data store profile and a number of parameters that specify particular data desired from the external data store. A profile within the profile service instance includes an attribute that names the data store reference object. When the attribute is evaluated, the data store reference object is instantiated, optionally using parameters specified at runtime, and passed as a parameter to an instance of the data store connector class identified by the external data store profile. The external data store connector instance applies the query methods to retrieve the desired data and return the desired data to the data store reference object. The profile service instance uses the returned data as the value of the attribute.

摘要： The strongly adsorbed component of a gas mixture is produced in enhanced purity and yield by novel PSA cycles. The basic steps of the cycles include an adsorption vessel prepressurization step, a cocurrent nonadsorbed gas production step, a cocurrent purge step with strongly adsorbed gas product and a countercurrent depressurization step which produces the strongly adsorbed gas product that is used in the cocurrent purge step. In addition to the basic steps, a first depressurization equalization step precedes or follows the cocurrent purge step and a corresponding first pressurization equalization step follows the countercurrent depressurization step. The cycle optionally includes one or two depressurization equalization steps before the cocurrent purge step and one or two corresponding pressurization equalization steps after the first pressurization equalization step.
