Abstract: A power converter (P) for a data cable (c), the power converter (P) comprises an input (Pi) for establishing an electrical connection with electrical power wires (epw) of the data cable (c), an output (Po), and a converter section (Pc). The converter section (Pc) is configured to: receive electrical power having an input voltage (Vi) from the electrical power wires (epw), and use an inductance (Lc) of the electrical power wires (epw) for converting the electrical power having the input voltage (Vi) into electrical power having an output voltage (Vo), and to transmit the electrical power having the output voltage (Vo) to the output (Po).

Abstract: A device (2) for determining optimal equalizer settings (setE_opt) for an equalizer (1) for equalizing a pulse amplitude modulation signal (L0, L1, L2, L3) comprises an estimator section (21) configured for receiving at least a part of the equalized pulse amplitude modulation signal (L0?, L1?, L2?, L3?) from the equalizer (1), and for receiving an offset signal (offS), and for generating an estimator signal (estS) indicative of a percentage of signal levels of the at least a part of the equalized pulse amplitude modulation signal (L0?, L1?, L2?, L3?) which are larger or smaller than the offset signal (offS).

Abstract: A pressure regulator assembly includes an integrated body. The integrated body has an inlet for connecting to a gas cylinder, a bore extending from the inlet to a pressure regulator, a passage extending from the pressure regulator to an outlet, and a fill port in communication with the bore. The pressure regulator assembly includes the pressure regulator operable to reduce pressure of a fluid flowing therethrough between the bore and the passage to a sub-atmospheric pressure; and an isolation valve operable between an open position and a closed position. The isolation valve is operable to seal the passage from the outlet in the closed position and to provide fluid communication between the outlet and the passage in the open position.
