  • Patent number: 9030357
    Abstract: A method for identifying transmitters by a terminal in a single-frequency network comprising a plurality of transmitters. The transmitters are synchronized and transmit with an artificial delay ?i, specific to each transmitter. The method comprises at least one step of acquiring the approximate position of the terminal {circumflex over (p)}, the position pi of a list of transmitters {Tx} in the vicinity of the terminal and the delays ?i associated with them, a step of measuring pseudo-distances ?i between the transmitters and the terminal and a step of associating the measurements ?i with the transmitters of known positions pi by minimizing a cost function, said cost function ?(?i,{circumflex over (p)},?) corresponding to the norm of the error between the measurements ?i and a model of measurements of the pseudo-distances applied to a permutation of the position of the transmitters ?.

  • Patent number: 6254660
    Abstract: The invention relates to a Cr2O3-forming alloy that is resistant to oxidization and/or corrosion at high temperature, especially by glass, characterized in that it contains, in dispersion within its matrix, chromium oxide Cr2O3, or a precursor of this oxide. This alloy can be prepared by powder metallurgy using a process of hot consolidation of metallic powders, in particular by sintering. The alloy is especially suitable for articles which are to be used in a high-temperature oxidizing or corrosive environment.
