  • Patent number: 8402124
    Abstract: A methodology for balancing demand for networked services in a distributed data processing system is presented. Each client is uniquely associated with a local service manager; one or more local service managers are located throughout a distributed data processing system, and each local service manager provides access to networked services for associated clients. Each local service manager is uniquely associated with a distributed service manager; one or more distributed service managers are located throughout the distributed data processing system, and each distributed service manager provides access to networked services for associated local service managers. A client sends a service request to its local service manager, which returns information about a matching service to the client after finding a matching service that has characteristics that match parameters in the request.

  • Patent number: 8090480
    Abstract: A mechanism for managing energy consumption of electrical devices within a home or building. Energy usage data is collected for a first electrical outlet connected to an unidentified electrical device in a facility. A pattern of energy usage is determined from the energy usage data collected at the first electrical outlet. The pattern of energy usage of the first electrical outlet is then compared against known patterns of energy usage for one or more other electrical outlets. Responsive to identifying a match between the pattern of energy usage of the energy usage data collected at the first electrical outlet and a known pattern of energy usage of a second electrical outlet in the one or more other electrical outlets, the electrical device connected to the first electrical outlet is identified as the same electrical device that is associated with the known pattern of energy usage of the second electrical outlet.

  • Patent number: 8032627
    Abstract: A method of enabling transaction probes used to monitor a transaction or modify a primary application handling the transaction. The method begins with retrieving a token associated with the transaction. The token contains information regarding which transaction probes from a plurality of transaction probes will be enabled with respect to the transaction. The token is then read to determine the set of transaction probes from the plurality of transaction probes that will be enabled. The determined set of transaction probes is then enabled.

  • Patent number: 7958241
    Abstract: A network service allocation device is disclosed. The device comprises a probe, a module, and an engine. The device collects performance data relating to the physical characteristics of a distributed data processing system. The module utilizes the performance data to identify two or more node clusters on the distributed data processing system. The engine correlates the node clusters and one or more performance rules as related to the network service to provide a map of node cluster(s) for supporting the network service, or a list of one or more servers within a node cluster for supporting the network service.

  • Patent number: 7898832
    Abstract: A switched mode converter is disclosed that includes mode logic for switching between voltage mode and current mode. The converter includes sensing circuitry for sensing current on the primary side, load current on the secondary side, and converter output voltage. When load current is less than a predetermined value, the converter operates in voltage mode wherein output voltage of the voltage mode controller is used to control the duty cycle of a PWM controller. When load current is greater than a predetermined value, the converter operates in current mode wherein primary current is used to control the PWM controller. Thus during a light load when the converter is voltage controlled there is no need for a minimum load to stabilize the control loop. In current-mode the control loop will have faster transient response and avoid flux imbalance. Thereby providing advantages of both voltage and current controlled switched mode converters.

  • Patent number: 7805736
    Abstract: The present invention addresses the problem of linking cross-process and cross-thread subtransactions into a single user transaction. The mechanism of the present invention employs bytecode inserted probes to dynamically detect out of process correlating tokens in an inbound request. The bytecode inserted probes retrieve the correlating token in the inbound request. Based on the correlating token retrieved, the bytecode inserted probes are then used to dynamically determine if the inbound user request should be recorded and linked to a transaction that began in another thread or process.

  • Patent number: 7782636
    Abstract: A switched mode converter is disclosed that includes mode logic for switching between a voltage mode and a current mode. The converter includes circuitry for sensing current on the primary side of the transformer, load current on the secondary side, and output voltage. When the load current is less than a predetermined value, the output voltage of the voltage mode controller is used to control the duty cycle of a PWM controller. When the load current is greater than a predetermined value, the primary current is used to control the PWM controller. During a light load the converter is voltage controlled and there is no minimum load needed to stabilize the control loop. In a current-mode, the control loop will have a relatively faster transient response and avoid flux imbalance in push-pull topology. The converter provides the advantages of both known voltage controlled and current controlled switched mode converters.

  • Publication number: 20100194353
    Abstract: A switched mode converter is disclosed that includes both voltage mode and current mode control. The switched mode converter also includes mode logic for switching between a voltage mode and a current mode. The converter includes current sensing circuitry for sensing the switcher current on the primary side of the transformer and the load current on the secondary side as well as voltage sensing circuitry for sensing the converter output voltage. When the load current is less than a predetermined value, the converter operates in a voltage mode. During the voltage mode, the output voltage of the voltage mode controller is used to control the duty cycle of a pulse width modulation (PWM) controller. When the load current is greater than a predetermined value, the converter operates in a current mode. In a current mode, the primary switcher current is used to control the PWM controller.
