  • Patent number: 8341174
    Abstract: A method and apparatus for obtaining context information from a context server maintaining a context for an object of interest in a telecommunication network. The context server receives raw context data from sensors associated with the object of interest. A request is received from a requesting party for refined context information with reference to the object of interest. Individual context data is collected for at least one individual entity of the requesting party. A customized rule is created on the basis of the received individual context data. The rule defines conditions in an adapted request for refined context information regarding the object of interest, which is sent, including the customized rule, to the context server of the object of interest. Context data refined according to the customized rule is then received from the context server.

  • Patent number: 8341484
    Abstract: A first transceiver that supports hybrid Automatic Repeat Request (hybrid ARQ) functionality is operated. Initially, it is operated to transmit data blocks having a nominal maximum data block size, M0. In response to detecting that a second transceiver does not have sufficient soft buffer memory space to store data blocks associated with an anticipated number of active hybrid ARQ processes, the transceiver is operated to transmit data blocks having a reduced data block size, M?. The anticipated number of active hybrid ARQ processes can be, for example, higher than a nominal number of active hybrid ARQ processes.

  • Patent number: 8322435
    Abstract: A pressure driven pumping system includes a piston disposed within a first bore of a housing to separate a process chamber from a working chamber. A rod member coupled to the separating member extends into a reduced pressure chamber. The piston has a first face exposed to the process chamber and a second face exposed to the working chamber. The second face has an effective area less than an effective area of the first face. The housing may be placed in seawater at a selected depth. The process chamber can be in fluid communication with a well to pass well fluid into the process chamber at well pressure to move the piston, to discharge seawater from the seawater chamber. The working fluid, typically seawater in a subsea application, is pumped into the working chamber to move the piston, which discharges well fluid from the process chamber.

  • Patent number: 8325742
    Abstract: A network bridge comprising two ports for connection to two networks, a spanning tree controller and a wireless bridge link controller for each port. The ports employ an adaptive modulation technique. The wireless bridge link controller is connected to the port to exchange physical layer information with said port. When the port detects a change of its PHY mode, it sets the path cost of the link to a value configured for the new PHY mode and forces the bridge to recalculate its spanning tree. The wireless bridge link controller is also connected to the spanning tree controller. If the bridge detects that it has not received BPDUs for a certain time period and the timer will expire soon, the bridge forces the port, via the wireless bridge link controller, to use a more robust PHY mode.

  • Patent number: 8325781
    Abstract: The presence of spread spectrum signals in a given frequency range is detected in a receiver by receiving a signal; determining for a measurement frequency an indication signal; and using it as an indication of the presence of spread spectrum signals having a carrier frequency equal to the measurement frequency. An in-phase signal and a quadrature signal are provided by mixing the received signal with an oscillator signal having the measurement frequency; at least one of these signals is phase shifted; a sum signal and a difference signal are generated; and the sum signal is multiplied by the difference signal and low pass filtered. In this way a method and a circuit of detecting the presence of spread spectrum signals in a given frequency range are provided, which are simple and fast enough to be used in low-cost cognitive radios.
