    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： 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 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： A process is set forth for purifying and liquefying a feed gas mixture with respect to its less strongly adsorbed component of lower volatility which integrates temperature swing adsorption (TSA), pressure swing adsorption (PSA) and cryogenic distillation to optimize overall performance. The TSA portion of the process is used to remove the strongly adsorbed component from the feed; the PSA portion of the process is used to remove the moderately strongly adsorbed component from the feed; and the cryogenic distillation portion of the process is used to remove the less strongly adsorbed component of higher volatility from the feed while also providing for the liquefaction of the product. A key to the present invention is the use of the PSA and distillation waste streams in the regeneration of the TSA and PSA adsorbents. An important application of the present invention is the purification and liquefaction of a natural gas feed stream with respect to its methane/C.sub.2 hydrocarbon component.
