  • Patent number: 8335547
    Abstract: The described method and system allows for the utilization of a telematics unit on a telematics-equipped vehicle to prevent the unauthorized discharge of a vehicle battery. A user may communicate an authorization request for allowing discharge of the vehicle battery through a telematics unit or telematics service provider (TSP) call center. If approved by the TSP call enter or telematics unit, an authorization, which may include an authorization code, is communicated to a charge controller which controls the discharge of the vehicle battery. Alternatively, the user may communicate an authorization code directly to the telematics unit which passes it on to the charge controller for approval.

  • Patent number: 8327935
    Abstract: A method for fracturing a subterranean formation penetrated by a well bore comprises formulating a fracturing fluid useful in hydrocarbon drilling having the properties of both a dispersing fracture solution and an aggregating fracture solution. In particular, the dispersing properties of the stabilizing fracture solution are able to act as a dispersing fracture fluid in the clay and earthen materials discharged from the pay zone in the flow-back fluids during hydraulic fracturing. At the same time, aggregating properties of the stabilizing solution stabilize the pay zone. This stabilization property allows the flow of hydrocarbon through the fractures for a significantly longer time than with prior art fluids.

  • Patent number: 8331245
    Abstract: A method and a system for Internet Protocol (IP) session keepalive monitoring, a home gateway and a network device are provided. The method includes: receiving, by a User Equipment (UE) or an IP edge node, a Bidirectional Forwarding Detection (BFD) message sent by a Home Gateway (HGW), in which a first discriminator field value included in the BFD message is a difference between an IP address prefix of the UE and an IP address prefix of the HGW; and monitoring, by the UE or the IP edge node, whether an IP session between the IP edge node and the UE is keepalive according to the first discriminator field value in the BFD message. “Multihop BFD” is used as a keepalive monitoring mechanism of a “Multihop IPv6 Session”, thereby realizing keepalive monitoring of the “Multiple hop IPv6 Session”.
