Abstract:
The invention pertains to a method of detecting and calculating height of a jump performed by an individual, comprising the following steps:A detection of a reception subsequent to the jump, this step comprising a sub-step of detecting a pressure spike of amplitude greater than a first threshold amplitude, within pressure measurements provided by a pressure sensor embedded aboard a watch worn on the wrist of the individual,A calculation of a height of the jump by differencing a starting altitude corresponding to a last stable pressure measured before the pressure spike and a finishing altitude corresponding to a first stable pressure measured after the pressure spike via the pressure sensor, a stable pressure being defined as a pressure whose variations do not exceed 0.1 hectopascals for at least 2 seconds.

Abstract:
Wristwatch comprising a mechanical device for executing a first mechanical function arranged to produce a first acoustic alarm signal, and an electronic device housed in a bracelet and arranged to produce a second acoustic alarm signal and/or a mechanical vibration, wherein the electronic device is arranged to produce the second acoustic alarm signal at the moment when the mechanical device for executing the first mechanical function produces the first acoustic alarm signal.
Abstract:
The timepiece comprises means for indicating the sunrise and sunset taking account of seasonal variations. These means comprise a sphere reproducing the terrestrial globe, a shell arranged concentrically to the sphere and arranged to demarcate one portion of the terrestrial globe where it is night from another portion where it is day by indicating the position of the Earth's terminator. The shell can pivot about the globe on two axes perpendicular to each other. The shell is driven by the movement so as to rotate at a rate of one revolution per 24 hours about the polar axis. A disconnecting mechanism is controlled by an annual cam which has a profile representative of the tilt of the Sun with respect to the equatorial plane. The disconnecting mechanism controls the tilt of the shell about the axis by means of a drive shaft concentric to the polar axis.
Abstract:
A device for measuring the accuracy of a mechanical watch includes a time reference source, a calculating mechanism, and another data processing unit. The time reference source is formed by an internal time reference source, or by a receiving and processing mechanism arranged to receive and process signals transmitted by an external time source to permanently update a repeater clock internal to the device. The calculating mechanism is arranged to calculate time differences between display values, and/or between time reference points provided by the time reference source, and to calculate a variation in rate. The another data processing unit is arranged to store and process at least one variation in rate calculated by the calculating mechanism, and/or a viewing mechanism arranged to display at least one variation in rate calculated by the calculating mechanism.
Abstract:
The timepiece comprises means for indicating the sunrise and sunset taking into account seasonal variations (17, 27). These means comprise a sphere (17) representing the Earth, a shell (27) arranged concentrically to the sphere and arranged to delimit a part of the globe where it is night time from another part where it is daytime by indicating the position of the Earth's terminator. The shell can pivot around the globe along two perpendicular axes (X-X, Y-Y). The shell is driven by the movement in order to revolve at the rate of one revolution every 24 hours around the polar axis (X-X). A differential mechanism (50) is controlled by a year cam (72) that has a profile representing the inclination of the sun in relation to the equatorial plane. The differential mechanism controls the inclination of the shell around the axis (Y-Y) by means of a drive shaft (35) concentric to the polar axis (X-X).
Abstract:
The smart battery includes an electronic circuit for managing the supply voltage connected to a battery. The electronic circuit includes a battery end-of-life detector, a management unit, an oscillator stage, a DC-DC converter powered on when the supply voltage of the battery is close or equal to a battery end-of-life threshold, and a data or command communication interface. The data or command communication interface is a 1-wire interface which is connected to a positive supply voltage terminal of the smart battery for transmitting a modulated data or command signal through one of the supply voltage terminals. The modulated signal transmitted by the interface may include battery end-of-life information.
