Abstract: A method of controlling a marine seismic streamer towed by a vessel includes deploying a workboat next to a section of the streamer and receiving, at the vessel, from the workboat, a command to enter a maintenance mode. In response, a locking command is transmitted via a streamer data link to direct a bird attached to the streamer to lock movable surfaces thereof. A user interface on the vessel is locked so that control of the bird is no longer available therethrough. A control apparatus for marine seismic operations includes the user interface, a receiver to receive commands from the workboat, a streamer interface to command the birds, a memory recording locations and identifiers of the birds, and a processor configured to carry out the method steps. A marine seismic detection system includes the streamer, a maintenance controller in the workboat, and an integrated navigation system controller in the vessel.

Abstract: A method for setting frequency channels in a multi-hop wireless mesh network including a plurality of nodes. Each node hops on frequency channels, with a hop period, according to a frequency channels hopping sequence. All data packets transmitted by the nodes have a duration strictly longer than the hop period. When a given node of the plurality of nodes is in a first transmit mode in order to transmit a data packet, it carries out steps of: selecting a transmit frequency channel as a function of the frequency channels hopping sequence; and transmitting the data packet using, for the entire duration of the data packet, the selected transmit frequency channel.

Abstract: A communication method is provided in a communication network, including a plurality of devices forming an ordered communication segment. At least one intermediate device of this segment is connected to at most two other devices called a previous device and a next device. The intermediate device receives data from the previous device and emits at least these data to the next device to propagate the data on the segment. A concentrator initializes transmission of a first frame of data through the segment to a terminal device ending the segment, which sends back a symbol initiating transmission of a second frame of data to the first concentrator through the segment. The method includes receiving a first symbol from the previous device, which triggers emitting a WAIT symbol to the previous device and emitting at least first symbol to the next device.
