  • Patent number: 10140573
    Abstract: Methods and apparatus are provided for processing in an artificial nervous system. According to certain aspects, resolution of one or more functions performed by processing units of a neuron model may be reduced, based at least in part on availability of computational resources or a power target or budget. The reduction in resolution may be compensated for by adjusting one or more network weights.
    Type: Grant

  • Patent number: 8767676
    Abstract: A network device includes a transceiver and a control module. The transceiver transmits, from the network device to a first access point, first packets and second packets, transmits a request signal to a second access point to perform a handover of support for the network device from the first access point to the second access point, and receives a control message from the second access point based on the request signal. The transceiver receives the control message subsequent to transmitting the first packets to the second access point. The control message indicates the second access point received, during the handover, the first packets from the first access point, and one of the first packets from the network device. The control module, based on the control message, refrains from transmitting the one of the first packets, discards the first packets, and has the second packets transmitted to the second access point.

  • Patent number: 8270369
    Abstract: A network device includes a transceiver that transmits N packets to a first access point and that receives a control message from a second access point. The control message indicates reception of one of the N packets by the second access point from the first access point during a handover of the network device from the first access point to the second access point. N is an integer. A control module causes the transceiver to refrain from transmitting the one of the N packets to the second access point based on the control message. The handover of the network device from the first access point to the second access point occurs prior to the control message being received by the transceiver.

  • Publication number: 20090190572
    Abstract: A service request device includes a transceiver that receives a downlink signal that includes at least one of an unreserved value, a resource status value, and a reserved value from a base station. The downlink signal is transmitted when a non-contention-based resource of the base station is not available for the service request device. A control module initiates a contention-based access procedure that synchronizes the service request device with the base station based on the at least one of the unreserved value, the resource status value, and the reserved value. The transceiver receives packets from the base station in response to the service request device being synchronized with the base station.

  • Publication number: 20070171892
    Abstract: An approach is provided for supporting special call services and applications in a data network. A request message is generated for establishment of a voice session over a data network. The request message specifies that the voice session is special as to permit a non-subscriber to establish the voice session for a predetermined duration.
