Instancing an application emulating a virtual fluid meter able to communicate directly with the data concentrator for each fluid meter in the plurality, and, for each fluid meter in the plurality, the corresponding virtual fluid meter takes responsibility for retransmitting information representing a fluid-consumption reading, said information having been supplied to the reading system by said fluid meter to the management entity via the data concentrator.

The present invention is directed to a system and method of remotely controlling a welding machine with command signals transmitted to the welding power source across a weld cable connecting the power source to a remote device, such a wire feeder. A transmitter transmits the control commands containing desired welding operational parameters to a receiver disposed in the power source across a weld cable also designed to carry welding power from the power source to the wire feeder.

A system for controlling a level of communication signals broadcast onto an associated power line communication (PLC) network by an associated transmitting device includes an input circuit, an adjustable amplifier circuit, and an output circuit. The input circuit receives a first communication signal having a first signal level from the associated transmitting device. The adjustable amplifier circuit applies a selectable gain to the first communication signal based on one or more of a monitored condition of the associated vehicle and/or a monitored condition of the associated PLC network to generate a level-adjusted communication signal having a second signal level different than the first signal level of the first communication signal. The output circuit receives the level-adjusted communication signal and broadcasts the level-adjusted communication signal onto the associated PLC network.

A wired communication systems, a subscriber device and a method, and more specifically related to initialization and/or update of communication parameters used for communication through the wired communication systems. An access node comprises at least one processor and memory storing instructions that when executed by the at least one processor cause a local transceiver of the access node to transmit signaling data via a subscriber line to a remote transceiver, the signaling data identifying particular symbol positions within a sequence of symbols transmitted over the subscriber line during show-time as being suitable for characterizing a direct communication channel between the local transceiver and the remote transceiver.

A power line communication apparatus includes a first power line communication device disposed at a signal transmit end, a second power line communication device disposed at a signal receive end, a power line, a first magnetic ring disposed at the signal transmit end, and a second magnetic ring disposed at the signal receive end. The second power line communication device receives the modulated signal from the power line. The power line includes a wire for transmitting electric energy and a shield layer that wraps the wire for electromagnetic shielding. The wire and the shield layer separately extend from the signal transmit end to the signal receive end. The first magnetic ring and the second magnetic ring are separately coupled to the shield layer, to suppress inductance attenuation of the magnetic ring and improve reliability of the transmitted modulated signal.

The adaptive filter circuitry includes error sample generation circuitry configured to generate error samples representing a difference between a target response and the filtered data samples, arithmetic-only circuitry configured to approximate a windowing function to operate on the error samples, and output sample generation circuitry configured to operate on windowed error samples to provide the output filtered data samples. The comparison circuitry may be configured for time-domain operation and may further be configured to transform the error signals into frequency-domain error signals.

A system for providing powerline communication over flexible mesh for circuit design used in biometric monitoring is disclosed. In particular, the system provides for the transmission of power and data over the same circuit infrastructure, and integrates the ability to transfer data over an infrastructure that also transmits power. Notably, the system facilitates the integration of data over power in flexible systems, such as systems incorporating flexible mesh sensors and flexible geometric systems. The dual use of power infrastructure reduces weight and increases flexibility and potential sensor density. The systems use of data over power significantly reduces or eliminates the needs for a standalone data bus, thereby reducing the design complexity of the circuit.
