  • Publication number: 20060168334
    Abstract: A method is disclosed for application layer message-based network element management of server failures. According to one aspect, a network element such as a router intercepts session state information that is contained in a request from a client and locally stores the session state information. As a result, application servers to which the requests are directed do not need to store the session state information. If an application server fails, then the network element can use the session state information stored at the network element to continue the session with another application server, transparently to the client application that is involved in the session.

  • Publication number: 20060166398
    Abstract: A multilayered printed wiring board having a ball grid array (BGA) land pattern in which each land in the pattern is connected to a respective via by a link connector, a method of adapting spacing between selected adjacent via and respective link pairs to receive decoupling capacitor pads, comprising rotating, elongating and/or truncating the selected adjacent pairs and rotating their respective corresponding via pairs to adapt the spacing between the selected adjacent via pairs in the BGA land pattern and applying the capacitor pads to the selected via pairs. The selected adjacent via pairs and their respective link connectors are rotated, elongated and/or truncated in mutually opposite directions.

  • Publication number: 20060129689
    Abstract: A method is disclosed for reducing the sizes of application layer messages in a network element such as a network switch or router. According to one aspect, the network element receives data packets and determines an original application layer message that is collectively contained in payload portions of the data packets. The network element compresses the original application layer message into a compressed message, and sends the compressed message toward an application that is hosted on a device other than the network element. According to another aspect, the network element receives data packets and determines a compressed message that is collectively contained in payload portions of the data packets. The network element decompresses the compressed message into an original application layer message, and sends the original application layer message toward an application that is hosted on a device other than the network element. Compressed messages consume less network bandwidth.

  • Publication number: 20060123425
    Abstract: A method is disclosed for high-speed processing of structured application messages in a network device. According to one aspect, a network device receives a set of message classification rules that have been prepared beforehand by a system administrator or customer. The system analyzes the message classification rules to determine what part(s) of the message are necessary to classify a message according to the message classification rules. This allows the system to consider only the relevant parts of the message and ignore the rest of the message. The system extracts the portion of the message necessary for classifying the message and classifies the message using the values of the extracted information and the message classification rules. A unique sequence of operations is implied by the message classification and those operations must then be applied to the message.

  • Publication number: 20050162839
    Abstract: A solution for mounting decoupling capacitors on a printed wiring board (PWB) used for mounting a high performance ball grid array (BGA) device is described. The via array that connects the BGA device is modified, the modification being that at least a portion of one row of said vias array is missing at least two adjacent vias. The missing vias are replaced by respective shared vias in an adjacent row, and the shared vias are connected to either a power supply or a power return. The shared vias are also provided with via pads on the other side of said PWB, and a decoupling capacitor can be electrically connected across the pair of via pads to decouple the power supply and the power return at the two adjacent vias.

  • Publication number: 20050093881
    Abstract: A method and apparatus for extensible real-time workflows are described. The present invention allows a user of a transaction processing system, such as a customer relationship management (CRM) tool or an automatic call distribution (ACD), for example, to easily add new event sources without recompiling the core workflow server engine of the transaction processing system. The invention also supports features such as the adding of new services, the exchange of events and parameters with other systems, real-time collection and display of workflow statistical information, the use of a centralized configuration database, incremental loading and unloading of workflows and rules, and exception handling.

  • Publication number: 20030100350
    Abstract: A telephone includes an indicator which alerts a user that the telephone has stopped receiving data and is ready for transmission. Thus, when operating as a speakerphone, the indicator alerts the user that the other party has stopped speaking and the user may begin speaking. The indicator may also indicate that the telephone is receiving data and the telephone is not ready for transmission.

  • Patent number: 5032099
    Abstract: A toy musical box having an electronic musical sound reproduction circuit and an electric motor drive for an endless band carrying a continuous picture past a window, so that the musical box can resemble a television set. The operation of the sound reproduction circuit and the motor are remotely controlled by sound impulses from a separate hand-held device, the musical box having a microphone and a discriminator to provide an output signal upon receipt of the sound impulses. Preferably a double sound impulse is acquired to operate the musical box, eg. two clicks one immediately following the other, for differentiation from other extraneous sounds.
