Abstract:
A timepiece includes a first oscillator oscillating at a first frequency and connected by a first gear train to an energy source to display the time. The timepiece also includes a chronograph system including a second gear train connected to the first gear train via a coupling device for selectively measuring a time. The chronograph system further includes a second oscillator, which is connected to the second gear train and oscillates at a second frequency. Moreover, the second gear train is connected to the first gear train by an elastic coupling, in order to synchronize the rate of the two oscillators using the same energy source when the coupling device is in a coupled position.

Abstract:
The receiver (1) picks up low rate FSK radio frequency signals. This receiver includes an antenna (2) for receiving FSK radio frequency signals, a low noise amplifier (3) connected to the antenna, a local oscillator (7) for supplying oscillating signals (LO), a phase shift circuit (16) for performing a 0° to 90° phase shift, and vice versa, in the oscillating signals (LO) or the incoming FSK radio frequency signals in each semi-period of a phase switching cycle (1/fs). The phase shift circuit alternately and successively generates in-phase and quadrature oscillating signals, or in-phase and quadrature incoming FSK radio frequency signals. The receiver includes a single mixer (4) for mixing the oscillating signals successively with the incoming FSK radio frequency signals, so as to generate alternately intermediate in-phase and quadrature baseband signals (INT) as a function of the phase shift circuit. The receiver further includes a low-pass filter (8) for filtering the intermediate in-phase and quadrature signals, and a demodulation stage (20) for demodulating the data (DOUT) from the filtered intermediate signals. The receiver is arranged such that the phase shift circuit (16) is switched by a phase selection signal (SEL) to a phase switching cycle frequency (fs) which is lower than the frequency deviation (Δf) of the modulated data in the FSK radio frequency signals and higher than the data rate frequency. Magic circuits (14, 15) in the demodulation stage reconstruct the intermediate signals during each switch operation for continuous demodulation in the demodulator (12).
