  • HYDROPHILIC FENTANYL DERIVATIVES
    Publication number: 20180273475
    Abstract: Various fentanyl derivatives are described. The derivatives exhibit high binding affinity to opioid receptors, but also have decreased blood brain permeability as compared to standard fentanyl. This, the resulting derivatives can be less addictive than standard fentanyl. Methods of making such derivatives are also disclosed in this document.

  • Malleable Error Control Code Structures suitable for Adaptive Error Protection
    Publication number: 20180205394
    Abstract: In various implementations, a method includes determining a sequence of source packets. In some implementations, the sequence of source packets satisfies a windowing condition. In various implementations, the method includes synthesizing a first set of one or more parity packets as a function of a first set of source packets in the sequence. In some implementations, the first set of source packets satisfies a first encoding pattern. In various implementations, the method includes synthesizing a second set of parity packets as a function of a second set of source packets in the sequence. In some implementations, the second set of source packets satisfies a second encoding pattern that is different from the first encoding pattern. In some implementations, the first and second encoding patterns characterize an encoding structure determined as a function of a channel characterization vector.

  • Forward error correction for low-delay recovery from packet loss
    Patent number: 9843413
    Abstract: An encoder receives a sequence of packets. For each packet, the encoder selects a window of at least previous packets in the sequence of packets. The encoder identifies in the window one or more earlier packets among the previous packets and one or more later packets separated from the one or more earlier packets by a gap including gap packets. The encoder encodes the one or more earlier packets and the one or more later packets into a forward error correction (FEC) packet corresponding to the packet, without using any of the gap packets, and transmits the FEC packet and the packet.
