The watch (2) comprises a memory (4) and a detection device (6) comprising an acceleration sensor (8), capable of measuring an acceleration vector of the watch in a three-dimensional reference frame of this watch, and an electronic unit (12) arranged to be...

L'invention se rapporte à un dispositif électronique (1), notamment une montre électronique, comprenant un boîtier (2) et un système électronique (3) agencé dans le boîtier (2), le boîtier (2) étant muni d'un logement (14) pour une batterie (5) p...

The process involves updating a reference pressure value (Pref) based on ambient pressure measurement, where the value is used to detect the beginning of a dive. The value stored before being updated is saved as a protection value (Psauv) of the value (Pre...

The method involves comparing a value of variation in pressure between measured ambient and reference pressure values to a trigger threshold. A dive mode is activated if the variation value is higher than the threshold, and the value is compared to a prese...

The device has an electronic circuit to control hour and minute needles (10, 11), in a historic mode, such that the needles indicate change of a stored value of a physical quantity such as pressure or temperature, according to time, in comparison with scal...

The button type battery (1) is situated in a housing within the equipment base (2) and is secured by tongues (5) which extend from the housing floor and have retaining tips (11) at their ends (9). The action of the retaining tips is reinforced by the lid (...

The portable instrument, for example a watch, is carried on a bracelet (4) and includes an electronic circuit and a rechargeable battery. The bracelet has two contact pads (10,11) that are pressed against complementary pads on a battery charger, and two co...

A battery inside a wristwatch or similar instrument is recharged through two different diameter recessed charger contacts (10,11) built into the watch strap (4) adjacent to the buckle (14). The contacts are connected to the battery by flexible conducting t...

An induction charger recharges an accumulator which supplies electric power to the wristwatch. The charger has primary winding and secondary winding (2) that is housed in the strand of wristwatch.

There is described a time base comprising a resonator (4) and an integrated electronic circuit (3) for driving the resonator into oscillation and for producing, in response to the oscillation, a signal having a determined frequency. The resonator is an int...
