  • Publication number: 20250123202
    Abstract: A method for measuring the attenuation coefficient of a scattering and/or absorbing part of a body using diffuse reflectance spectroscopy. The method includes emitting optical radiation, the intensity and/or the optical frequency of which are modulated, with at least part of the optical radiation, called a probe signal, irradiating the body; receiving part of the probe signal, called a backscattered signal, that is scattered and reflected by the body and measuring the path length of the backscattered signal; measuring the reflectance of the part of the body traversed by the backscattered signal; and computing the attenuation coefficient based on the measured path length and on the reflectance.

  • Patent number: 12212426
    Abstract: According to some embodiments, an Ethernet Virtual Private Network (EVPN) includes a first router configured as an Internet Group Management Protocol (IGMP) version 3 querier and a second router configured as an IGMP version 2 querier. The second router is configured to receive a Selective Multicast Ethernet (SMET) route message generated by the first router. The SMET route message includes an IGMP version 3 join request from a receiver, and the IGMP version 3 join request includes an address of a multicast source device. The second router is further configured to convert the IGMP version 3 join request of the SMET route message to an IGMP version 2 join request. The second router is further configured to send multicast traffic from the multicast source device to the receiver via the first router.

  • Patent number: 12003406
    Abstract: A method, network device, and computer program product for network traffic diversion are disclosed. In one embodiment, a method according to the present disclosure includes receiving a frame at a core edge node that is a member of a redundancy group (where the frame comprises network address information and a packet), and determining whether a link is affected by a network failure. The frame was sourced by a remote core edge node that is not a member of the redundancy group, and the network address information indicates that the packet is to be forwarded via the link. In response to the link being affected by the network failure, the method further includes generating a modified frame and forwarding the modified frame to another core edge node. The generating comprises including a redirect label in the modified frame. The another core edge node is another member of the redundancy group.

  • Publication number: 20240176207
    Abstract: A current-assisted photonic demodulator includes a detection portion having two doped modulation regions and two doped collection regions, lying flush with a first face covered by a dielectric layer. Electrodes pass through the dielectric layer and come into contact with the doped regions. In addition, intermediate electrodes partly pass through the dielectric layer and are spaced apart from the first face by a non-zero distance, each being located, in projection in a main plane, between one of the doped modulation regions and the adjacent doped collection region.

  • Patent number: 11945359
    Abstract: The ratchet tie-down tensioner includes a ratchet engagement head actuated by a tensioning bar, a tie-down engagement head connected to a tie-down winding shaft, a ratchet engaged with outer inclined teeth of the tie-down engagement head and a ratchet drive mechanism located between the two engagement heads. The drive mechanism includes a self-centering crown floatingly supported in the body and a gear attached to the ratchet engagement head and mounted in the self-centering crown. The gear has a toothing on the outer periphery thereof which is provided to engage with the inner toothing of the self-centering crown, at least one of said toothings comprising curved spring blades. Said tie-down tensioner makes it possible for tensioning cycles to be performed by moving the bar back and forth.

  • Patent number: 11431608
    Abstract: In one embodiment, a method according to the present disclosure includes receiving a topology change advertisement at a remote core edge node and performing a network address information removal operation. The topology change advertisement is received from a core edge node that is in communication with an access network. The topology change advertisement indicates that a topology change has occurred in the access network. The network address information removal operation removes network address information stored by the remote core edge node. The network address information is used by the remote core edge node in participating in communications with the core edge node.

  • Publication number: 20220247669
    Abstract: A mechanism that allows CE-to-PE traffic to achieve minimal traffic loss at the same rate as PE-to-CE redirection (FRR). The solution relies on a fast-unblocking of the Backup-DF interface based on appearance of redirected packets from the active DF-Elected peer. A slow-path confirmation mechanism is included to further mitigate false-positives, as well as maintaining data plane and control plane in sync.

  • Patent number: 10760595
    Abstract: The security unit ensures, by blocking the hydraulic flow, that the rod of a cylinder is held in position. It includes two preferably twinned isolation devices, each mounted on one of the hydraulic lines supplying fluid to a chamber of the cylinder. Each isolation device includes two series-connected ball-check valves allowing the flow in the direction of inlet of the fluid into the respective chamber; and a longitudinal, separate rod, inserted between the balls but not linked thereto, and capable of being slidably guided towards each of the balls and driving same. The rod is too short to contact both balls simultaneously when the two valves are closed; but it is sufficiently long to push the ball of the second valve, thereby causing it to open, when it slides under the pushing action of the ball of the first valve upon the latter being controlled to be opened.
