Method and apparatus for measuring web site performance
A web site is provisioned with a proxy that receives a page request intended for the server and records a first time. The page request is then forwarded to the server for response. The response stream generated by the server is intercepted at the proxy at a second time. As the stream is forwarded to the requesting client, the proxy inserts a page script that, upon execution at the client, calculates a page render time. This time is determined by calculating the difference between a third time (the time at which the page script begins execution at the client) and a fourth time (a time at which the page rendering is complete). Upon completion of the page rendering, the script opens a connection back to the server and returns a packet that includes the page render time. This packet is received at a fifth time. A transaction record is then built by the proxy using the timestamp data.

The disclosed system displays the user-specific topology to the user after a subsequent user log-in to the Web portal.
Node discovery involving multiple node enumerators
A network node discovery method allows multiple enumerators to concurrently accept and interpret the same enumeration responses from responder nodes on a network. In this manner, the responder nodes do not have to issue individual responses for each enumerator. Each responder maintains a discovery state and one or more per-enumerator session states to manage when the responder should transmit enumeration responses. The enumeration, therefore, proceeds at a target network load, irrespective of the number of enumerators present, and completes in a short time by making efficient use of the network capacity available. Furthermore, an enumerator can determine that it need only wait for responses solicited by other enumerators, rather than requesting them, thereby reducing network traffic in the presence of many concurrently enumerating nodes.

After the Internet TV has transmitted the requested authentication number to the portal server and the server has checked the transmitted authentication number, information is provided to the Internet TV. Because the portal server provides the authentication number to each Internet TV, the portal server is able to confirm the access authority of each Internet TV, thus allowing each Internet TV to automatically access the portal server without an individual user login.

Agent-based clustering of abstract similar documents
A continuous, emergent, anytime process clusters input documents according to a similarity function within a node-based, distributed computing environment, for example, within a client/server environment. An agent (DAg) assigned to each document determines whether its document should remain at a node or be moved to another node to increase similarity clustering. An agent (SAg) assigned to each node may be operative to manage storage requirements within its node, and/or manage communications between the nodes of the environment as the DAgs operate. Typically a move request is issued to another node if it is determined that clustering would increase by moving a document to that node. In such an instance, the SAg assigned to that other node would probabilistically consider the move request in view of other such requests in sequence to avoid overloading. To enhance performance, documents may be preprocessed and given values representative of similarity. The similarity between two arbitrary documents may then assessed as the average difference between the values assigned to the same attribute in the two documents.

Symbol synchronization using phase discontinuity for DVB-T systems in AWGN channels
At a receiver incoming coded OFDM Symbol Data are passed through a Coarse Symbol Timing Synchronization module to determine the approximate start of the symbol. In one embodiment this is accomplished through correlation. The symbol is then passed through an FFT (2K or 8K, depending on the mode desired by the receiver). Since the Coarse Symbol Timing Synchronization module only determines an approximate start point of the symbol, a process of fine synchronization is used to adjust this approximate start point and determine a more accurate start point of the symbol. In this manner, the receiver is enabled to process COFDM symbols in DVB-T transmissions (where the symbols include a cyclic prefix to overcome echoes). One output of an FFT operation is magnitude. Magnitude is used for Channel Estimation (or Channel Correction). Another output of an FFT operation is phase discontinuity or rotations.

Poly-phase AC/DC active power converter
A three-phase AC/DC active power converter provides an H-bridge that is controlled by a DSP (digital signal processing) controller that places the H-bridge in a voltage-boost mode of operation when voltage of a DC-link capacitor maintained by the H-bridge is near than the voltage input from a three-phase power source. The voltage difference between the boosted DC-link voltage and the three-phase power source voltage provides a voltage potential thereby giving the control loops a possible gain value. The gain value provides loop stability to thereby prevent an inrush of electrical current into the power converter upon startup. The converter also allows harmonic distortion to be modified through wave shaping of the normally pure sinus conduction signal.
