  • Publication number: 20070223529
    Abstract: An inter-departure time of a pair of TCP segments, or a mean inter-departure time of a block of TCP segments, is determined and an inter-arrival time of a pair of non-duplicate acknowledgments is determined. The bandwidth of a data network may be estimated based at least in part on the inter-arrival time if the inter-arrival time is not less than the inter-departure time or the mean inter-departure time.

  • Publication number: 20070223395
    Abstract: A plurality of network characteristics of a wireless network are determined and a plurality of TCP session parameters are updated. The network characteristics may be determined based at least in part on a comparison of the estimated bandwidth and estimated propagation delay of the wireless network and the typical bandwidths and propagation delays of one or more wireless networks. The TCP session parameters may be updated based at least in part on the network characteristics. The TCP session parameters may be used to limit the congestion window, retransmission timeout and slow start threshold.

  • Publication number: 20070223492
    Abstract: During a Transmission Control Protocol (TCP) session, a congestion window and slow start threshold may be limited to a range defined by a minimum congestion window and a maximum congestion window based at least in part on the network type of a wireless network. The network type of a wireless network may be determined based in part on one or more round trip times of one or more data segments and one or more TCP session parameters are set to corresponding stored session parameters that are associated with the network type.

  • Publication number: 20070114266
    Abstract: A method and device to elongate a solder joint are provided. The method begins by forming an elongator on a first substrate. The elongator comprises an expander and an encapsulant to encapsulate the expander. A solder joint is formed to connect the first substrate to a second substrate. Thereafter, the encapsulant is softened to release the expander from a compressed state to elongate the solder joint. The device to elongate a solder joint comprises a substrate having an elongator formed on it. The elongator includes an expander in a compressed state and an encapsulant to encapsulate the expander.

  • Publication number: 20070040565
    Abstract: A compliant interposer sheet probe card and a method for testing a wafer or a wafer level package using the probe card are described. Test electronic circuits are connected on one side of a multi-layer substrate. A top side of a compliant interposer sheet is connected to an opposite side of the multi-layer substrate. A wafer or a wafer level package to be tested is contacted with pins on a bottom side of the compliant interposer sheet whereby the wafer or wafer level package can be tested.

  • Patent number: 7032022
    Abstract: A unified policy management system for an organization including a central policy server and remotely situated policy enforcers. A central database and policy enforcer databases storing policy settings are configured as LDAP databases adhering to a hierarchical object oriented structure. Such structure allows the policy settings to be defined in an intuitive and extensible fashion. Changes in the policy settings made at the central policy server are automatically transferred to the policy enforcers for updating their respective databases. Each policy enforcer collects and transmits health and status information in a predefined log format and transmits it to the policy server for efficient monitoring by the policy server. For further efficiencies, the policy enforcement functionalities of the policy enforcers are effectively partitioned so as to be readily implemented in hardware.

  • Publication number: 20060057832
    Abstract: A wafer level package formed on an integrated circuit chip having bondpads and a fabrication method therefor is disclosed. The wafer level package comprises at least one first, second and third separation layer having at least one first and second conductive layer formed in-between the separation layers. The at least one first conductive layer is formed on the at least one first separation layer and is coupled to the bondpads. The at least one second conductive layer is formed on the at last one second separation layer wherein the at least one second conductive layer is electrically coupled to the at least one first conductive layer. The at least one third separation layer allows solder to be attached to the at least one second conductive layer for electrically coupling the solder to the bondpads. A chip ground plane is laid in the integrated circuit chip for providing a ground to the at least one first conductive layer and the solder.

  • Publication number: 20050183120
    Abstract: A media distribution technique employs a multi-user server positioned at the terminal end of a broadcast media network. The server receives broadcast media signals and selectively captures a portion of the signals for live personalized media streaming and/or storage for later personalized media streaming and/or download over a local distribution network to a collection of user receivers. Request/control streams sent from the receivers to the server control real-time personalization of the media streams such as trick-play functions and channel selection. Buffering and data storage segmentation techniques are used to provide highly responsive personal video recorder-like functionality to the multiple end users.
