  • Patent number: 8620605
    Abstract: A method for detecting and determining a position of faults using reflectometry in a wired electrical network including: injecting a test signal e(t) into a cable in the electrical network, a timing of successive injections being controlled by a synchronization module that generates an emission clock signal and a reception clock signal; retrieving a reflected signal on the cable; sampling the reflected signal at a frequency Fe=1/Te, where Te is a sampling period; counting a number of samples obtained for the reflected signal and comparing the number of samples obtained with a number n predefined as a function of a length of the cable or the electrical network to be diagnosed, where n is an integer; repeating the injecting, the sampling, and the counting steps N times, shifting the emission clock signal by a duration ?; reconstituting the reflected signal from n*N samples obtained; and analyzing the reconstituted reflected signal to detect a fault.

  • Publication number: 20130158892
    Abstract: A method for selecting, from a plurality of processing resources capable in an information-processing system of carrying out one and the same type of process, one of the resources so that it carries out a process of said type, the method including estimating the probable time to failure for each of the resources, the resource being selected so that the probable times to failure of the resources evolve in a substantially identical manner.

  • Publication number: 20110015882
    Abstract: This invention relates to a method for detecting and determining the position of faults using reflectometry in a wired electrical network comprising the following steps: inject a test signal into a cable in said network, retrieve a reflected signal on said cable, sample said reflected signal at a frequency Fe=1/Te, repeat the previous steps N times, where N is an integer number, for each injected test signal, retrieve n samples from the corresponding reflected signal, where n is an integer number, analyse M=n*N retrieved samples to detect and locate a fault in the wired electrical network. The method is characterised in that the retrieved samples are compared with an adaptive threshold defined for each diagnostic as a function of the test signal injected in the tested cable.
