Abstract: The disclosure relates to a communications system having a transmitter and receiver connected via a transmission line. An example communications receiver (202) comprises: a pair of input connections (211, 212) for connecting to a transmission line (203); a termination resistance (213) equal to a characteristic impedance (Zc) of the transmission line (203); an air core transformer (205) having an input coil (206) connected to the pair of input connections (211, 212) via the termination resistance (213); and a comparator circuit (208) connected to an output coil (207) of the air core transformer (205), the comparator circuit (208) configured to provide an output signal (504) responsive to detection of voltage pulses across the output coil (207).

Abstract: Aspects of the present disclosure are directed to a method and/or apparatus for use with battery cells having an actual voltage-sourcing level that is at or above a specified battery-output level. Switch circuitry is selectively activated for passing current, and a monitoring circuit is responsive to activation of the switching circuitry by distributing energy corresponding to an actual voltage-sourcing level of a particular one of the battery cells to a voltage node. A voltage-measurement circuit provides an indication of the actual voltage-sourcing level across the particular battery cell by ascertaining voltage differentials between the voltage node and respective voltage nodes of the battery cell, the ascertained voltage differentials being less than the specified battery-output level.

Abstract: Embodiments provide redundant voltage measurements for battery management systems. A first stack of battery cells is monitored with a first battery cell controller (BCC), and a second stack of battery cells is monitored with a second BCC. At least one battery cell is a common battery cell shared by the first stack of battery cells and the second stack of battery cells. For one embodiment, a single common battery cell is used. A failure of the first BCC or the second BCC is then determined based upon monitoring of the common battery cell. If failure is detected with respect to the BCGs, an action is taken to protect the battery pack including the first stack of battery cells and the second stack of battery cells. In addition, diagnostic voltage levels can also be used to facilitate the determination of a failure for the first BCC or the second BCC.

Abstract: A method for processing a voltage signal relating to the pressure prevailing in a combustion chamber of a cylinder of an internal combustion engine, the signal, referred to as an “input signal”, having, in alternation, “plateau” phases and main peak phases. The method includes a step (E1) of rectification of the input signal such that the gradient of the base signal is zero, a step (E2) in which the peaks of the rectified signal of which the amplitude is greater than a predetermined voltage value are clipped so as to obtain an at least partially clipped signal referred to as a “clipped signal”, a step (E3) of detection of a main peak when the amplitude of the input signal is greater than the amplitude of the clipped signal, and a step (E4_1, E4_2) of compensation of the input signal in the absence of such a detection.
