Abstract: It is proposed a method for providing synchronization in a data acquisition system including a plurality of acquisition units. A given acquisition unit of the plurality carries out the following steps: receiving a packet from another device of the data acquisition system; extracting a synchronization accuracy information and a reference clock information from the received packet; obtaining a first reference clock as a function of the extracted reference clock information; if the extracted synchronization accuracy information indicates a better synchronization accuracy than a current synchronization accuracy information associated to the given acquisition unit: taking the obtained first reference clock as a selected reference clock and updating the current synchronization accuracy information to indicate a lower synchronization accuracy than the extracted synchronization accuracy information.

Abstract: A hybrid sensing apparatus for collecting data inside a well, the apparatus including an optical cable that acquires a first set of data; and an array of discrete probes connected to each other with an electrical cable. The discrete probes are configured to acquire a second set of data. The apparatus further includes an attachment system attached to the discrete probes and configured to hold the optical cable. The attachment system is configured to expose the optical cable to directly contact the well.

Abstract: A method for waking up a distant device from a local device, through a transmission medium and distant and local media converters. Initially, at least one of the physical and link layer units of the distant device is off, and its processing layer unit is off or in Low Power mode. The transceiver of the distant media converter is on. When receiving an initial wake-up signal from the local device, the transceiver of the distant media converter generates an electrical wake-up signal converted from the initial wake-up signal. The transceiver of the distant media converter sends the electrical wake-up signal, or derived wake-up information, to the processing layer unit of the distant device, through a transmission line independent of the physical and link layer units of the distant device. When receiving the electrical wake-up signal or the wake-up information, the processing layer unit of the distant device turns on.

Abstract: A communication system includes a node configured to collect ambient data with a sensor, and a docking station configured to couple to the node and to establish a communication path with the node through only one signal along one or two wires. The node includes a first module configured to use a first data communication protocol for receiving commands from the docking station along the communication path, and a second module configured to use a second data communication protocol for sending the ambient data to the docking station along the communication path. The first data communication protocol is different from the second data communication protocol, the first data communication protocol is asynchronous and the second data communication protocol is a modified synchronous protocol.

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.
