A method (P) for coding a solar time, called the initial solar time (Hs), associated with a geographical location (Loc) and with a day (J) of the year, wherein the method includes selecting SEL(Href, Nb) a reference time (Href) and an initial number of bits (Nb) as a function of the type of initial solar time (Hs), computing CALC(Nm) a number of minutes (Nm) separating the initial solar time (Hs) and the reference time (Href), coding COD(Hs) the number of minutes (Nm) in the initial number of bits (Nb).

Method for coding and transmitting at least one solar time

A method for transmitting data from an electronic device to an electronic watch, including the following steps: emitting a sequence of light signals with a light source of the electronic device, each signal having a light-intensity level belonging to a set of at least four light-intensity levels, said sequence corresponding to a code of the data to be transmitted; detecting successive light-intensity levels with a phototransistor of the watch, so as to reconstitute the sequence; and decoding the sequence in order to reconstitute the data, the set of at least four intensity levels being divided into a first portion and a second portion, one light signal in two of the sequence having a light-intensity level belonging to the first portion, the other signals having a light-intensity level belonging to the second portion.

Method for transmitting data synchronously from an electronic device to an electronic watch

A universal moon phase display device for a watch including a device that calculates or receives the date, that receives a geolocation signal, that calculates or receives a lunar calendar with the correlation between the date of the moon phase, that converts the day's moon phase into a first angular position of a first display member included in this device and which includes a representation of the normal moon, and that further determines the northern or southern hemisphere in which this device is located and controls the direction of rotation of first drive device included in this device in order to drive the first display member in opposite directions in the northern hemisphere and in the southern hemisphere.

Universal moon phase display

A method for transmitting data from an electronic device to an electronic watch is provided, including emitting a first sequence of light signals with a first light source of the device at a light-intensity level among at least four light-intensity levels, the emitted first sequence corresponding to a code of data to be transmitted; emitting a second sequence of light signals at two light-intensity levels corresponding to clock phases, simultaneously to the emitted first sequence, with a second light source of the device; detecting successive light-intensity levels with a first phototransistor of a watch, to reconstitute a sequence of data; detecting a succession of the two light-intensity levels with a second phototransistor of the watch, to reconstitute the clock phases, the first and the second sequences emitted at two distinct wavelengths; and decoding the sequence of data by a sequence of the clock phases to reconstitute the data.

Method for transmitting data asynchronously from an electronic device to an electronic watch

An electronic module including at least one electric motor for driving an analog display, a clock module including a time base delivering a clock signal connected to a divider circuit, the divider circuit delivering a reference signal sent to a control circuit arranged to control the electric motor, the clock module further including a measuring and correction circuit arranged between the time base and the divider circuit and delivering an intermediate compensated signal. The time base, the compensation module, the divider circuit, and the control circuit are arranged in a same case to form the clock module.

Thermocompensated chronometer circuit

The present invention concerns an electronic device comprising a calculation unit capable of generating a signal representative of a physical magnitude, for a motor driving a display device, said motor comprising a rotor in a magnetic circuit, two terminals, one positive and one negative, via which the calculation unit controls the motor, the electronic device further comprising at least one shock detector circuit connected between the calculation unit and a motor terminal for the detection of an external shock applied to the motor,

Shock detector circuit and method for operation thereof

The wristwatch () is provided with an electrical connector (), which is connected via a connection element () to at least one electronic circuit and/or to a rechargeable battery which are disposed inside the watch case. The electrical connector () is a female USB electrical connector, which is disposed on an inner surface of the bracelet (), and where the bracelet is fixed to the middle part () of the watch case. The inner surface of the bracelet comes into contact with the user's wrist when the watch is worn. The connection element () passes through the middle part to connect a contact area of the electrical connector to the electronic circuit and/or the rechargeable battery inside the case.
