Abstract: An impeller, fan assembly, and associated methods are shown. Selected configurations are shown that include a circumferential feature formed within a plate of an impeller and spaced apart from edges of the plate.

Abstract: An apparatus and method are described for forwarding of packets with controlled delay. In one embodiment, the invention includes controlled delay queuing logic to hold a packet in a first class for a queuing time of at least a controlled delay value, and scheduling logic to determine whether to delay transmission of a packet in a second class to allow the transmission of the packet in the first class when the queuing time reaches the controlled delay value.

Abstract: A method and structure for the distribution and utilization of synchronization within an asynchronous network is described herein. Synchronization is distributed through an asynchronous network via a synchronization symbol periodically inserted on the MAC layer. The priority of this symbol ensures that this symbol is inserted in the MAC layer data stream ahead of all other types of symbols. The insertion of the synchronization symbol in the middle of an ongoing data frame is supported. In addition, a method for synchronization symbol distribution throughout an asynchronous network is presented, along with a method for switching to a new synchronization path (in the event of loss of original synchronization path) based on minimum number of hops from the synchronization source.

Abstract: A method and system for distributing work load in a cluster of at least two service resources. Depending upon the configuration, a service resource may be an individual process, such as a single instance of a computer game, or a node on which multiple processes are executing, such as a Server. Initial connection requests from new clients are directed to a single entry-point service resource in the cluster, called an intake. A separate intake is designated for each type of service provided by the cluster. The clients are processed in a group at the service resource currently designated as the intake to which clients initially connected, for the duration of the session. Based upon its loading, the current intake service resource determines that another service resource in the cluster should become a new intake for subsequent connection requests received from new clients. Selection of another service resource to become the new intake is based on the current work load of each resource in the cluster.

Abstract: A method and apparatus for adjusting the position of an antenna to improve reception at a television includes a signal generator which measures the signal strength received by the antenna. The signal generator sends a low frequency coded signal to a display visible to a person who is adjusting the antenna. The display provides a quantitative indication of the signal strength to the installer of the antenna, allowing precise adjustments to be made in accordance with the displayed value. The signal generator provides the coded signal to the display via the same cable used to carry the received signals from the antenna to a receiver, such as a set-top box.
