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: 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: This invention relates to a data communication system/method for use in a downhole application wherein electrical energy is supplied over a multiple-conductor power cable to a motor assembly of a downhole tool such as an electric submersible pump. A power leg coupling interfaces a surface controller of a downhole instrument to the conductors of the tool's power cable. Uplink communication of telemetry data occurs via current modulation generated by the downhole instrument and interpreted by a surface controller. Downlink communication of downhole instrument data occurs over a different communication scheme supported by the downhole and surface controllers. Downlink communication scheme provides a supply of power to the downhole instrument. Protection of downhole electronics and continuity of communication is ensured in the event of a ground fault on the power cable. Both downlink and uplink communication frequencies are adaptive based on frequencies and voltages present on the power cable.
