Abstract:
A system and method to determine an angular movement of an arbor integral with a crown of a watch, the arbor being rotatable in a longitudinal direction. Included is a rotating reflector mounted on the arbor, and two emitter/detector pairs disposed on either side of the reflector. Each emitter/detector pair includes a light source for illuminating the reflector, and a light detector for receiving the light reflected on the reflector and for generating an electrical signal representative of the reflected light. A processor processes the electrical signals and determine a parameter relating to the angular movement of the arbor. The rotating reflector's visible outer surface changes when the reflector rotates on itself in a regular manner, such that the representative electrical signal generated by said detector of the pair has a substantially sinusoidal shape when the reflector rotates on itself in a regular manner in a same direction of rotation.

Abstract:
A moving indicator for an analogue display device, in particular for a timepiece. The indicator includes a multi-layer part including an opaque metal layer and a transparent light guide layer and forming a body and a head of the indicator. The head is centred relative to a rotational axis of the indicator and arranged to receive a luminous flux on the bottom face thereof. A fluorescent material is arranged on the transparent light guide layer at the head of the indicator to absorb at least part of said luminous flux and to re-emit a second luminous fluorescence flux in the transparent light guide layer. Other aspects comprise a set of indicators, a display device and a watch comprising one or more moving indicators.
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.
