Abstract: A reflectometry system includes at least one measurement means for measuring a reference signal retro-propagated in at least one transmission line, at least one analog-digital converter for converting at least one measured signal into a set of at least one first digital signal and one second digital signal, at least one complex correlator configured to correlate the real reference signal with a complex signal whose real part is formed by a first digital signal of the set and whose imaginary part is formed by a second digital signal of the set, so as to produce a first reflectogram corresponding to the real part of the complex signal and a second reflectogram corresponding to the imaginary part of the complex signal, an analysis module for analyzing at least the first reflectogram and the second reflectogram so as to identify the presence of defects in at least one transmission line.

Abstract: The present invention relates to a method and a device for enhancing the reliability of a system comprising a plurality of processors and a memory. The method comprises a step of grouping processes into a plurality of groups and a step of saving, individually for each group of processes, data stored in the memory which can be used by at least one of the processes belonging to said group, so as to restore an error-free global state of the system following an error occurring in a processor executing one of the processes belonging to said group without having to restore the entire memory.
