Abstract: In a pedometer device (1), for detecting and counting steps of a user on foot, an accelerometer sensor (2) detects a vertical acceleration generated during the step. A processing unit (3) is connected to the accelerometer sensor (2), processes an acceleration signal (CalAcc) relating to the acceleration (A) in order to detect the occurrence of a step, and in particular compares the acceleration signal (CalAcc) with a first reference threshold (S + ). The processing unit (3) automatically adapts the first reference threshold (S + ) as a function of the acceleration signal (CalAcc). In particular, the processing unit (3) modifies the first reference threshold (S + ) as a function of an envelope (Env') of the amplitude of the acceleration signal.

Abstract: A barometric-pressure-sensor device (20), in particular for a portable electronic device (50), is provided with a pressure sensor (1) of a MEMS type designed to supply a barometric-pressure measurement, and with a processing circuit (22, 23) coupled to the pressure sensor (1) and designed to supply an altitude measurement as a function of the barometric-pressure measurement. The pressure sensor (1) and the processing circuit (22, 23) are integrated in a single chip (20c), and the processing circuit (22, 23) is a dedicated circuit of a purely hardware type. The processing circuit (22, 23) executes altimeter-setting operations, through a plurality of reference registers (27-29) containing respective pressure references.

Abstract: A method for controlling a pedometer includes the steps of: generating a signal (A z ) correlated to movements of a user of the pedometer; and detecting steps (200-225, 300-320) of the user on the basis of the signal (A z ). The method moreover envisages the steps of checking whether sequences of detected steps (K-2, K-1, K) satisfy pre-determined conditions of regularity (230, 320, 345); updating a total number of valid steps (N VT , 265, 325, 350) if the conditions of regularity (230, 320, 345) are satisfied; and preventing the updating of the total number of valid steps (N VT ) if the conditions of regularity (230, 320, 345) are not satisfied.
