    摘要： A method (1) of processing signals by means of rescaling, comprising the steps of: − downscaling (10) an initial signal (11), in accordance with a predetermined downscaling factor (Df) to obtain a downscaled signal (12), − upscaling (20), the downscaled signal (12) to obtain an upscaled signal (13) having the same dimensions as said initial signal (11), − comparing (30) the initial signal (11) and the upscaled signal (13) to calculate a comparison parameter, − if said comparison parameter is within a previously defined range, decreasing (50) the downscaling factor (Df) and repeating the steps of downscaling (10), upscaling (20) and comparison (30), − if said comparison parameter is outside the previously defined range, encoding (40) an encoded signal (14) as a function of the downscaled signal (12).

    摘要： A method is described for driving a full-bridge circuit (34,64) comprising a circuit (31) generating a first output modulation signal (m1) and a second output modulation signal (m2) for controlling the full-bridge. The method comprises the steps for generating a first (X1) and a second (X2) square waveform having a common period (Ts), where the first waveform (X1) is configured in order to drive a leg of the full-bridge and the second waveform is configured in order to drive the other leg of the full-bridge. The method is characterized in that the first square waveform (X1) is generated with a first duty cycle based on a first modulation signal (m1); the second square waveform (X2) is generated with a second duty cycle greater than or equal to the first duty cycle of a time increment Ts/(N-1) based on the second modulation signal (m2).

    摘要： A method (100) of measuring chemical species in a sample by x-ray fluorescence comprising the steps of: - arranging (110) a sample to be analysed including one or more chemical species to be identified and measured, - exposing (120) the sample to x-radiation, - measuring a spectrum (130) associated with the chemical species, - recognising (140) the chemical species by identifying the energy value of one or more peaks of the spectrum, - calculating the mass (150) of each of the chemical species by analysing said spectrum, on the basis of the number of counts associated with each of the peaks (K, L) of the measured spectrum, the mass of each of said chemical species being calculated on the basis of the number of counts associated with each of the peaks (K, L), - a preliminary calibration step (101) wherein a linear relationship between the number of counts associated with each peak and the mass of the corresponding chemical species associated with said peak is identified by deposition of a plurality of calibration solutions on respective rough, impermeable surfaces (55) of respective calibration supports (50) that are identical to each other, each of said calibration solutions comprising a predefined amount of a chemical species.
