  • Patent number: 8233378
    Abstract: A method and apparatus for validating control and data plane association is described. In one embodiment of the invention, a first provider edge (PE) network element negotiates a pseudowire with a second PE network element. The pseudowire is uniquely identifiable between the first and second PE network element with a unique pseudowire identifier. The first PE network element receives OAM (operations, administration, and management) packets each including a pseudowire identifier from the second PE network element over the negotiated pseudowire. If an OAM packet is received with a pseudowire identifier that does not match the negotiated pseudowire, the first PE network element determines a data plane fault is associated with the pseudowire on the second PE network element. However, if the OAM packets include the pseudowire identifier that matches the negotiated pseudowire, the control and data plane association of the second PE network element is validated. Other methods and apparatuses are also described.

  • Patent number: 8233404
    Abstract: Control of uplink transmit power for a first mobile station operating with scheduled uplink data transmissions. A change in uplink scheduled status for the first mobile station is detected (301). Filtering of uplink interference measurements for the first mobile station is adapted (302) to account for the detected change in uplink scheduled status for the first mobile station. Alternatively a change in uplink scheduled status for a second mobile station is detected and a current filtering state for filtering of uplink interference measurements for the first mobile station is adjusted by applying an estimated expected change in interference associated with the detected change. A signal quality for uplink transmissions from the first mobile station is determined (303) based on measurements of received signal strength from the mobile station and the filtered uplink interference measurements.

  • Patent number: 8233517
    Abstract: A combination of parametric and non-parametric approaches are disclosed for enabling pilot-based SINR estimation for MIMO systems. The pilot-based SINR estimation embodiments account for precoding applied during either single-stream or multi-stream data transmission. The pilot-based SINR estimation embodiments also account for code reuse interference which arises during multi-stream data transmission when spreading codes are reused on the data channel. Accordingly, mismatches that exist between the data channel and the pilot channel because of precoding and/or code reuse are inherently accounted for by the pilot-based SINR estimation embodiments disclosed herein.

  • Patent number: 8231380
    Abstract: The invention concerns a combustion method for industrial furnace comprising an arrangement of two substantially parallel and symmetrical burner assemblies (G, D). Each burner assembly comprises a fuel injector (10<SUB>G</SUB>, 10<SUB>D</SUB>) and three oxidant injectors (1<SUB>G</SUB>, 2<SUB>G</SUB>, 3<SUB>G</SUB>, 1<SUB>D</SUB>, 2<SUB>D</SUB>, 3<SUB>D</SUB>) arranged at increasing distances from the fuel injector. An oxidant supply system cyclically distributes a specific flow of oxidant among some at least of the second and third injectors of the burner assemblies (2<SUB>G</SUB>, 3<SUB>G</SUB>, 2<SUB>D</SUB>, 3<SUB>D</SUB>). The amount of nitrogen monoxide produced upon combustion is thus reduced, while ensuring a good distribution of the heating power in the furnace.

  • Patent number: 8231650
    Abstract: An improved embolic filter frame having looped support struts. The frame configuration provides enhanced longitudinal compliance, improved sealing against a vessel wall, low profile delivery, and a short deployed length. The looped support struts have a high degree of “radial” stiffness with a low degree of “longitudinal” stiffness. In the deployed state, the frame exerts a relatively high stress onto a vessel wall to maintain an effective seal, yet remains compliant in the longitudinal direction. Minor displacements of the support wire or catheter are therefore not translated to the filter. The looped support struts elongate when tensioned and assume a compressed and essentially linear form. While constrained in this linear state by a delivery catheter, the support struts exert minimal stress onto the delivery system. The overall delivery profile and stiffness are therefore reduced.
