    • The invention concerns a method for exciting and monitoring a piezoelectric motor (M1) in stepping mode, the motor having a resonance frequency (f.sub.R) and being supplied electrically at an excitation frequency (f.sub.E) during each operating step. The method is characterized in that it comprises a monitoring phase which extends at least over several successive steps of said motor and in which, for a present step of said motor, a determined excitation frequency value (f.sub.E +1) is used, the duration (t.sub.E +1) of the present step is measured, said duration (t.sub.E +1) is compared to the duration (t.sub.E) of the preceding step and, according to the result of this comparison, said excitation frequency value (f.sub.E +2) is corrected for the following step in a direction tending to reduce the duration of the step. A circuit is also described which enables the implementation of the method.

    • The invention concerns a device for measuring a physical quantity, for example a force (A), and providing an output signal (Vs) whose amplitude represents the measured value. The device comprises a first oscillator (1) including a resonator (3) to which the force (A) is applied, this oscillator delivering a first alternating signal (S1) whose frequency depends on the magnitude of the force (A), a second oscillator (2) supplying a second alternating signal (S2) whose frequency is determined by the amplitude of the output signal (Vs), an EXCLUSIVE OR gate (20) receiving the first and second signals, and a low-pass filter (21) delivering the output signal (Vs) in response to a signal supplied by the gate (20). The amplitude of this output signal depends on the phase difference of the first and second signals, and constitutes a measurement of the magnitude of the applied force (A). The device is advantageously used when the measurement is to be displayed in analog form.

    • In an electronic watch, the content of the memory associated with the adjusting circuit of the division ratio of the frequency divider is modified at each correction of the display to compensate for the frequency error of the crystal oscillator and to thereby reduce the running error of the watch. Such electronic watches use a crystal oscillator whose frequency is not optimum. To compensate for the frequency variations due to manufacturing tolerances, age and temperature, correction circuits are incorporated into such watches. When an operator acts on a switch on the case of the watch to correct the time display indication, the content of the memory is modified to correct for the frequency error of the crystal oscillator.
