  • Patent number: 8774330
    Abstract: A coarse timing acquisition technique includes generating a sequence detection indicator. The sequence detection indicator indicates detection of a sequence of repeated symbols in a received signal. The sequence detection indicator is based on a first energy threshold and a normalized moving sum of an autocorrelation signal. The autocorrelation signal is based on the received signal.

  • Publication number: 20140095246
    Abstract: A system is provided that orchestrates a supply chain event. The system receives a supply chain event from an external source system. The system further retrieves a source document referenced by the supply chain event. The system further retrieves a supply chain financial orchestration flow assigned to the source document, where the supply chain financial orchestration flow defines a trade relationship between a first entity and a second entity. The system further selects one or more tasks defined for the supply chain financial orchestration flow. The system further initiates execution of the one or more tasks, where each task is executed at an external target system.

  • Publication number: 20130329968
    Abstract: Provided is a method of preventing an unauthorized publication of a media object. On receipt of a user request to prevent an unauthorized publication of a media object, a video link is established with the user. An image of the user is received from the video link and a determination is made whether the image of the user correspond with an image in the media object. Based on said determination an action is performed with regard to the unauthorized publication of the media object.

  • Publication number: 20130148767
    Abstract: A method of operating a communications system includes generating a channel impulse response estimate based on a first received signal. The method includes selecting a precursor and a cyclic prefix length for a second received signal based on the channel impulse response estimate, a target cyclic prefix energy level, and a predetermined range of cyclic prefix lengths.

  • Patent number: 8311820
    Abstract: Presented is a method and system for speech recognition. The method includes determining a noise level in an environment, comparing the determined noise level with a predetermined noise level threshold value, using a first set of grammar for speech recognition, if the determined noise level is below the predetermined noise level threshold value, and using a second set of grammar for speech recognition, if the determined noise level is above the predetermined noise level threshold value.

  • Patent number: 7706367
    Abstract: A method for processing data packets in an interception proxy server without using a Network Address Translation module. A TCP packet received at a router is encapsulated using generic routing encapsulation (GRE). The TCP packet is redirected to a proxy server through a GRE tunnel which includes a redirection rule comprising a local destination IP address and port to be used for traffic passed through the tunnel. When the proxy server receives the TCP packet, the TCP packet is decapsulated. If a flag is set in the payload header of the TCP packet indicating that a redirection rule has been configured for traffic passed through the tunnel, the payload header of the TCP packet is modified according to the redirection rule. The modified TCP packet is then passed to a transmission control protocol of the proxy server.
