Abstract (en)
[origin: WO2012171957A1] Device for measuring acceleration, comprising a mass (m) movable with respect to a support and returned elastically to a neutral position, means for detecting a physical magnitude (C1, C2) representative of a displacement (?x) of the mass, a moldulator (4) for generating, on the basis of the magnitude (C1, C2) and of a modulation signal (M(t)), an analog signal (S) representative of the displacement (?x), a convertor linked to the modulator and devised to convert the analog modulated signal into a digital modulated signal and means of demodulation for creating a digital demodulated signal (Y) on the basis of the digital modulated signal (S) and of characteristics of the modulation signal (M(t)), and means (CAL) for calculating a value (y) of acceleration (?) as a function of the demodulated digital signal (Y).
