Abstract: A method of detecting a movement of a timepiece setting stem arranged to be moved axially along and/or rotated about its longitudinal axis. The method includes a light source illuminating a portion of the setting stem; a light detector receiving a reflected or diffracted light pattern from the setting stem; a processor forming a first pixel pattern representative of the reflected light pattern at a first time instant; the processor forming a second pixel pattern representative of the reflected light pattern at a second, later time instant; and determining that the setting stem has been moved, if the second pixel pattern is different or shifted with respect to the first pixel pattern.

Abstract: The invention relates to a method for detecting and calculating the duration of a jump effected by an individual, comprising the following steps: Detection of a moment associated with a landing following the jump, this step comprising a sub-step of detecting an acceleration peak of an amplitude greater than a first threshold amplitude, within the acceleration measurements provided by a three-axis accelerometer, on board a watch worn on the wrist of the individual. Detection of a jump phase, by detection, in a temporal window finishing at the moment of landing, of a succession of acceleration measurements between 0 g and 0.5 g during a duration greater than a first threshold duration.

Abstract: A position sensor and method for determining an axial and/or an angular position of a setting stem of a timepiece. A magnet is provided on the setting stem, and at least one magnetic field sensor is configured to detect changes in magnetic field strength along at least a first axis and a second axis as the rotatable element rotates; the second axis is not parallel to the first axis. The changing magnetic field sensed by the magnetic sensor is converted into a characteristic signature path which may then be mapped onto a circular signature path in two dimensions to derive the angular position of the setting stem.

Abstract: A watch includes a control member which makes it possible to manage one or more electronic functions. The control member includes an optical guide, which extends between a proximal face and a distal face with respect to the middle. A light source is arranged such that it can illuminate the distal face through the optical guide, and an imaging device, including a photodetector, is arranged to capture an image of a portion of the finger of a user of the watch, when they touch the distal face. A processor generates commands based on signals generated by the photodetector, in the way of an optical mouse, for example, to make it possible for the user to browse in a menu displayed on a digital screen.
