A synchronizing system including a generation unit for generating a synchronizing pulse from data of an independent clock, the synchronizing pulse being generated in a periodic manner, transmission links to transmit the synchronizing pulse to all the computation units, and in each of the computation units, a control element to compare the synchronizing pulse that has been received to a pulse generated by an internal clock of the computation unit and to detect a compliance or a lack of compliance, a scheduler of each of the computation units activating a sequence of partitions when the synchronizing pulse is received, and this only if the control element has detected a compliance. The synchronizing system is configured to synchronize the computation units in a reliable and accurate manner and to increase the operating safety of these computation units.

The invention concerns a sensor simulation system. The simulation system () comprises a generator () that generates a digital signal by direct digital frequency synthesis, based on the following parameters: a frequency, an amplitude, a phase and amplitude shift; a digital/analog converter (), and a means () that modulates the signal received from said converter ().

A method and device for detecting an electrical arcing phenomenon operate to measure an electric current and an electric voltage on an electric cable. The measurements are filtered and the filtered measurements are digitized to produce two digitized data segments. Each of the two segments is subjected to a number of functions to produce a form vector. The membership class of the form vector is determined, and the presence or absence of an electric arcing phenomenon is determined from the membership class.
