  • Patent number: 8917597
    Abstract: A quality of service for various classes of services for the transfer of electronic data packets is provided by establishing classes of packets for a customer and for assigning bandwidths to the classes for the customer. Accordingly, the amount of bandwidth for one type of service may vary from the bandwidth for another type of service over the same data connection. A device, such as an edge router of a network, may police the data packets being transferred by a customer to maintain the bandwidth being utilized by a given class of packets of the customer to within the assigned bandwidth for that class of the customer. The data packets may further be policed by core routers of the network may also to maintain the bandwidth being utilized by a given class of packets to within the assigned bandwidth for that class as specified by the service provider.

  • Patent number: 8917726
    Abstract: A network utilizes centralized control for the transport of a packet flow to a destination via an intermediary network. The network identifies the intermediary network best suited for offloading the packet flow and then develops a routing policy based on Multiprotocol Label Switching or other circuit-switching type techniques. This ensures that the packets of the packet flow are automatically forwarded to a peering router connected to the identified intermediary network, and ensures that the peering router automatically outputs the packets of the packet flow to the identified intermediary network in a manner that bypasses autonomous routing decisions by the routers of the network.

  • Patent number: 8918321
    Abstract: Disclosed herein are systems, computer-implemented methods, and computer-readable media for enhancing speech recognition accuracy. The method includes dividing a system dialog turn into segments based on timing of probable user responses, generating a weighted grammar for each segment, exclusively activating the weighted grammar generated for a current segment of the dialog turn during the current segment of the dialog turn, and recognizing user speech received during the current segment using the activated weighted grammar generated for the current segment. The method can further include assigning probability to the weighted grammar based on historical user responses and activating each weighted grammar is based on the assigned probability. Weighted grammars can be generated based on a user profile. A weighted grammar can be generated for two or more segments.

  • Patent number: 8913991
    Abstract: A system and methodology that can customize screen time-outs on a portable electronic device based on user activity is provided. The system employs a sensing component that receives data from one or more sensors located on the portable electronic device, for example, skin conductivity sensors. The sensing component determines whether the user is using the portable device, either actively or passively and also determines the identity of the user. A configuring component is employed to change one or more features or functions of the portable electronic device based on the information determined by the sensing component. In particular, the configuring component changes one of more features of the portable electronic device based on the preferences predefined by the identified user and device usage (active and passive usage).
