  • Patent number: 11323302
    Abstract: Some aspects of the present disclosure relate to detection of a Phase Hit and, upon detecting the Phase Hit, determining the magnitude and location of the Phase Hit. Detecting the Phase Hit may involve comparing a phase offset difference for successive pilot symbol to a detection threshold. Determination of the detection threshold may involve a Neyman-Pearson binary hypothesis testing (NP-BHT) approach. Once the magnitude and location of the Phase Hit are known, data symbols received after the location may be processed to remove the magnitude of the Phase Hit.

  • Patent number: 11296800
    Abstract: Computational nodes are connected to each other via multiple point to point communication ports to form a mesh network. When a node receives such routing information, it will be a set of {Route ID, Forwarding Ports} pair, where the ports can be multiple targets including the node itself. When all the nodes within the routing path receive such information, the mesh system can handle the packet transfer for the given Route ID. Each node looks up the table with Route ID and determines where to forward the packet.

  • Patent number: 11252212
    Abstract: This invention concerns the transmitting and receiving of digital media packets, such as audio and video channels and lighting instructions. In particular, the invention concerns the transmitting and receiving of redundant media packet streams. Samples are extracted from a first and second media packet stream. The extracted samples are written to a buffer based on the output time of each sample. Extracted samples having the same output time are written to the same location in the buffer. Both media packet streams are simply processed all the way to the buffer without any particular knowledge that one of the packet streams is actually redundant. This simplifies the management of the redundant packet streams, such as eliminating the need for a “fail-over” switch and the concept of an “active stream”, The location is the storage space allocated to store one sample.
