  • Static neighbor wake on local area network
    Patent number: 8077712
    Abstract: In one embodiment, a method includes obtaining traffic that is to be forwarded to a neighboring device, and determining if the neighboring device is in a state that enables the neighboring device to receive the traffic. The method also includes automatically sending a first packet to the neighboring device if the neighboring device is not in the state that enables the neighboring device to receive the traffic. The first packet includes a bit sequence arranged to cause the neighboring device to awaken itself if the neighboring device is asleep.

  • Method and apparatus for processing data traffic across a data communication network
    Patent number: 7308506
    Abstract: A method is presented for processing data traffic between a correspondent node and a mobile node on the data communication network. Traffic from the correspondent node to the mobile node is intercepted and the mobile node home address is replaced as destination with the mobile node attachment address. Traffic from the mobile node to the correspondent node is intercepted and the attachment address is replaced as source with the home address.

  • Processing received data in a distributed speech recognition process
    Patent number: 6732072
    Abstract: A method of processing received data in a distributed speech recognition process. The method comprises the steps of comparing a received form of the common header information from each of a plurality of header frames; classifying a predetermined number of the same received form as a reference; and processing one or more received data frames whose received common header information is different to the reference by using the reference form instead of the received different form. Also described is an apparatus for processing received data in a distributed speech recognition process.
