  • Patent number: 11616373
    Abstract: A software and hardware architecture framework utilize the specifications of Universal Serial Bus (USB) Type-C and Power Deliver (PD) to provide fine grain throttling of a processor (e.g., system-on-chip (SoC)). Based on an external charger connection or disconnection, a low latency fine grain power budget loss or gain indication to the processor is delivered. The mechanism of various embodiments is also applicable to connection or disconnection of VBUS powered peripheral devices to the system. The net power loss or gain available to the SoC and System is proportionally used to scale the processor throttling.

  • Patent number: 8942167
    Abstract: A method, apparatus and computer program product for providing seamless Internet Protocol multicast connectivity in unified networks is presented. The systems disclosed herein are able to transfer, from a designated (i.e., first) VLAN to a roaming (i.e., second) VLAN, a multicast stream from a multicast server in a mobility VLAN that is not available at the roaming VLAN. In operation, example embodiments of the present invention receive a report identifying a roaming mobile unit as a member of a first VLAN and forward the report to a first mobility switch in the first VLAN. The multicast stream is then received and forwarded toward the roaming mobile unit in the second VLAN so that transfer of the multicast stream from the first VLAN to the second VLAN is seamless.

  • Patent number: 8913487
    Abstract: A method, system and computer readable medium for fast failover of an access point are described. A system can cause a failover of a first wireless access point when a wireless control point determines that a first wireless switching plane has failed through a platform link failure mechanism. The system can also prevent a failover of the first wireless access point or a second wireless access point when a message is received from both the first wireless switching plane and a second wireless switching plane indicating that the other wireless switching plane has failed.

  • Patent number: 7224984
    Abstract: An asset positioning method and system (700) rapidly and accurately determine the special location of wireless nodes distributed in three-dimensional space. Furthermore, as a by-product, every node also determines the relative offset and drift of every other node's clock, so that it is possible for all nodes to carry out a precise synchronized action (708). The positioning and synchronization protocol has significant implications for a broad range of wireless networking infrastructure and applications. For instance, the rapid availability of accurate location information greatly simplifies and optimises the implementation of ad-hoc networks and sensor-based applications (716). Additionally, the synchronized node operations facilitate the development of new applications, such as phase-locked arrays, in which several low power transmitters coordinate to form a powerful group transmitter.

  • Patent number: 7212522
    Abstract: Communicating voice over a packet-switching network is implemented on a telecommunications network that includes the packet-switching network, two coding units coupled to the packet-switching network and to an originating node and a terminating node, respectively, and at least one signaling apparatus. The first of the two coding units is configured to extract signaling data associated with the voice call and transmit the signaling data and its network address to the signaling apparatus. Signaling data for establishing the voice call is received by the signaling apparatus, and a network address of the coding unit in the packet-switching network is obtained. The second coding unit is controlled to establish a bearer channel with the first coding unit for carrying the voice data through the packet-switching network, based on the network address.
