  • Publication number: 20240067752
    Abstract: The present invention provides anti-HtrA1 antibodies (including bispecific anti-HtrA1 anti-Factor D antibodies) and methods of making and using the same, for example, in methods of treating HtrA1-associated disorders, ocular disorders, and/or complement-associated disorders.

  • Patent number: 9276613
    Abstract: The Universal Packet Loss Recovery System (UPLRS) is capable of recovering end-to-end network packet losses to obtain reliable end-to-end network delivery of multimedia streaming content over IP networks where packet losses appear above the transport layer. The UPLRS incorporates the use of Packet Forward Error Correction Coding (FEC) with packet interleaving processing prior to transport. Packet FEC is an error correction coding method at the packet level to improve link transmission reliability. At the source end of the packet-switching network, the Packet FEC scheme encodes a stream of transport multimedia content packets by including redundant packets in the stream to allow for the recovery of lost packets by the Packet FEC decoder at the user end of the packet-switching network. Since lost packets appear only above the transport layer in the IP network protocol stack, Packet FEC can be viewed as a transport layer or an application layer coding method.

  • Patent number: 9007984
    Abstract: A physical layer network coding architecture is provided to increase downlink capacity for satellite network architectures. For instance, a network coding controller may perform a XOR network coding operation on FEC encoded information received from a first terminal and second terminal, and broadcast a single downlink message containing the XOR network coded information to the first and second terminal.

  • Publication number: 20110105126
    Abstract: A handover method provides intrasatellite transmitter handover detection and decision using an unbiased weighted Signal Noise Ratio (SNR) estimator based on forgetting factors for SNR monitoring, and a threshold delay is introduced to ensure the reliability of handover decision to prevent undesirable handovers during beam switching.
