  • DELTA-SIGMA CONVERTER WITH PM/FM NON-LINEAR LOOP
    Publication number: 20190181878
    Abstract: A device, system and method for improvement of analog/digital conversion. An improved delta sigma-converter including a phase or frequency modulation and demodulation, is used. The improved delta sigma-converter obtains higher gains than traditional Delta Sigma converter, preserving or improving the oversampling and noise shaping gains of these converters.

  • POWDERED GRIT MADE OF A FUSED CERMET
    Publication number: 20130209920
    Abstract: Powdered grit comprising a fused cermet of zirconium oxide (ZrO2) doped with a dopant chosen from yttrium, scandium, and a mixture of scandium and of aluminium and/or of cerium, and of nickel (Ni) and/or of cobalt (Co), said cermet having a eutectic structure, the contents, in mol %, of zirconium oxide, nickel and cobalt being such that 0.250Ni+0.176Co?(ZrO2+dopant)?0.428Ni+0.333Co, and said powdered grit having a median diameter D50 of between 0.3 ?m and 100 ?m.

  • Signal processing device and method for detecting and locating spectral shapes
    Patent number: 8290459
    Abstract: Method and device for detecting a target spectrum and its frequency location in a scenario contaminated with strong jammers on other interferers. The detection is based on the geodesic distance between the correlation matrix (RD) of the received signal and the correlation matrix (RT) of the target spectrum (TS) which is assumed known in shape and bandwidth. The detection happens when the threshold (Formula (I)) is overcome. The frequency location is based on the minimization of the mean square error between RD and RT.
