  • Patent number: 10355993
    Abstract: Deterministic network interface for an avionic network, configured for two Ethernet physical media, with two neighboring network interfaces. The network interface of the invention allows the realization of ring-topology network without collision in the physical Ethernet media. The communication between nodes is carried out in a fully deterministic fashion by an unconnected (UDP) protocol. The interface of the invention incorporates a hardware end-to-end integrity mechanism that ensures message integrity from the memory of the sender host to that of the recipient one.
    Type: Grant

  • Publication number: 20180145909
    Abstract: Deterministic network interface (100) for an avionic network, configured for two Ethernet physical media (120, 220), with two neighbouring network interfaces (99, 101). The network interface of the invention allows the realization of ring-topology network without collision in the physical Ethernet media. The communication between nodes is carried out in a fully deterministic fashion by an unconnected (UDP) protocol. The interface of the invention incorporates a hardware end-to-end integrity mechanism that ensures message integrity from the memory of the sender host to that of the recipient one.

  • Patent number: 6760363
    Abstract: A correlation method and a digital correlation device allowing detection of the occurrence of a coded reference sequence including N code elements or chips in a sampled reception signal are described. The reception signal is sampled at a frequency equal to d times the chip rate of the reference sequence, and d×Nd correlation values are generated for d×Nd successive delays of the reception signal, Nd being a lower number than the number N of chips. Each correlation value, for a given delay of the reception signal, is obtained, according to the present invention, at the end of a plurality of correlation operations during which partial correlation values covering code portions including Nd successive chips of the reference sequence are generated.
