摘要:
There is disclosed a wristwatch having a case containing a mechanical watch movement (10) driven by a spring barrel (14) and provided with a mechanical regulator with a balance and balance-spring, which is associated, via electromagnetic coupling, with an electronic regulator driven by a quartz resonator. The rim of the balance (13) is provided with a pair of permanent magnets (38, 39). The electronic regulator includes a fixed coil (12) arranged for cooperating with said magnets via electromagnetic coupling, a rectifier (58) provided with at least one capacitor, and a circuit (60) for enslaving the frequency of the mechanical regulator to the frequency of the oscillator by braking obtained by briefly short-circuiting the coil. In order to enable a common type of mechanical movement to be used, only the balance of which is altered, the electronic regulator is formed by a structural module (11) that is entirely separate from the mechanical watch movement (10). This module can be fixed to the movement plate, or, conversely, carried by the watchcase independently of said movement, in particular via a casing ring (26). Apart from the coil, all of the rest of the electronic module (11) is preferably located outside the mechanical movement.

The timepiece (1) includes a mainspring (2) driving the rotor (3a) of an electromechanical converter (3) and time display hands (6). A circuit (7) for enslaving the real angular position of the rotor (3a) to its desired angular position is supplied with electrical energy by the converter (3). In order to increase the autonomy of the timepiece (1), the enslaving circuit (7) includes means (28) which store a portion of the electrical energy generated by the converter (3) and means (21, 23 to 27) which use this stored electrical energy to apply driving pulses (IM) to the converter (3) when the rotor (3a) has a greater retardation than a determined retardation, with respect to its desired angular position.
摘要:
The integrated circuit (11) of this timepiece comprises means (16, 17, 18) for comparing the frequency of a time base (12, 13) to the frequency of the generator (1). The error signal thereby generated is examined by a wired logic (20) allowing verification of whether this signal passes distinct threshold values. Passing of two of these values allows an electric brake (22) of the generator to be controlled so that from a certain degree of depletion of the power reserve of the barrel (5), the second hand moves periodically right away over an angle of several seconds inviting the wearer of the timepiece to rewind the spring (6) of the barrel (5).

There is disclosed a timepiece having a mechanical clockwork-movement (10) driven by a barrel spring (14) and provided with a mechanical regulator, with a balance and a balance spring, which is associated, via electromagnetic coupling, with an electronic regulator driven by a quartz resonator. The rim of the balance (13) balance is provided with at least one pair of permanent magnets (38, 39). The electronic regulator includes a fixed coil (12) arranged for cooperating with said magnets via electromagnetic coupling, a rectifier (58) provided with at least one capacitor, and a circuit for enslaving the frequency of the mechanical regulator to the oscillator frequency by braking obtained by briefly short-circuiting the coil. In order to use a mechanical movement of a common type, in which only the balance is altered, the coil (12) is located on the side of the balance-cock (23) with respect to the balance rim. The pair of magnets (38, 39) is covered by a plate of magnetic material in order to close field lines on the side of the plate. Apart from the coil, all of the rest of the electronic module (11) is located outside the mechanical movement.

A timepiece comprising a generator (1) for generating a supply voltage of a first predetermined value U.sub.1, a barrel with a spring (5, 6), a winding mechanism (5') and a set of hands (7 to 9). The electronic circuit (11, 12) of the timepiece requires a minimum limited supply voltage having a second predetermined value U.sub.2. This circuit comprises a timebase (12) and a regulating circuit (11) for regulating the rotational speed of the generator. According to the invention, a voltage regulator (25) is connected between the generator and said electronic circuit for adjusting its output voltage to said limited second value U.sub.2. The ratio between the absolute value U.sub.1 of the predetermined first value U.sub.1 and the second predetermined value satisfies the relationship U.sub.1 =k.multidot.U.sub.2, k being a factor corresponding at least to the maximum expected variation rate of the absolute value U.sub.1 when the timepiece is worn.

摘要:
This invention concerns a wireless data communication method, wherein a transmitter device having a first wide band antenna transmits ultra-wide band encoded data signals to a receiver device having a second wide band antenna for receiving the direct and/or multiple path coded data signals. The transmitted data is defined by one or several sequences of N pulses where N is an integer number greater than 1. The arrangement of the N pulses of each sequence represents a data coding relative to the transmitter device. The N pulses of a sequence of direct and/or multiple path coded data signals received by the receiver device are processed each in one among N corresponding reception time windows. Each of the N reception time windows is positioned in time based on a known theoretic arrangement of the N pulses of signals transmitted by the transmitter device. An adding operation of the N windows is then performed in the receiver device so that the amplitude level of the constantly added pulses is higher than the amplitude level of the noise sensed by the receiver device.

摘要:
An oscillator, such as a ring oscillator, uses CMOS transistors. At least some of the transistors have forward biased, current limited source-tub junctions for lowering the threshold voltages of these transistors. This enables the oscillator to operate at very low supply voltages, and it may be used in an electronic timepiece powered by a single photovoltaic cell.
