  • Publication number: 20070067125
    Abstract: The disclosure relates to a method for inspection of the quality of products produced by a production system, by monitoring the exhaustiveness, effectiveness and reliability of a traceability system associated with said production system. The method includes the following steps: determination of a plurality of domains of said traceability system to be inspected; determination of a plurality of criteria to be monitored for each of said domains, said criteria for a domain being correlated to each other; for each of said criteria, assignment of a numerical data representing a quality value by measurement through at least one sensor and/or by assessment; for each of said domains, multiplication of all said numerical data for each said criterion in said domain and application of a mathematical regression function to the resulting product to obtain a numerical data representative of a quality value of said domain; comparison of said numerical data with at least one predetermined threshold for each of said domains.

  • Patent number: 6812873
    Abstract: The invention concerns a method for decoding received digital data corresponding to transmitted digital data coded with an entropic code associating with each word of an alphabet a distinct bit sequence, whereof the length is a function of said word occurrence probability, using a decoding lattice whereof each transition corresponds to a binary value 0 or 1 of one of the bits of a sequence corresponding to one of said words.
