Power reserve indicator mechanism for horology

A power reserve indicator mechanism is for displaying the power reserve of an energy storage of a timepiece movement, powered in a winding phase by an input wheel actuated by a winding-stem or an automatic winding mechanism of the movement, or by an external winder, and arranged to restore energy in the unwinding phase via an output wheel. The power reserve indicator mechanism includes at least one display wheel set indirectly driven by the input wheel or by the output wheel, via a differential mechanism of which the input wheel and the output wheel constitute two inputs, and, at a single output, an output wheel set directly or indirectly driving the display wheel set.

11725094 · 2023-08-15 · ·

A solid material including a matrix, dispersed in which are microparticles of at least one antimicrobial agent for preventing, limiting and/or eliminating the contamination of the material and/or the contamination of a composition which is in contact with the material for at least a given time, and/or preventing, eliminating and/or slowing down the formation of biofilms on the surface of the material, wherein the antimicrobial agent is an oxide of at least one positively charged metal ion and the antimicrobial agent does not migrate out of the material. Also, the use of such material for manufacturing an article, to the process for manufacturing the article, and to the article obtained. In particular, the article is selected from stoppers, lids, seals, caps, covers, plugs and valves intended for sealing bottles, flasks, jars, cans, canisters, barrels, tanks, or various containers used for packaging and/or storing food products, dietetic products, cosmetic products, dermatological products or pharmaceutical products.

MECHANICAL HOROLOGICAL MOVEMENT WITH POWER RESERVE DETECTION

A mechanical horological movement (1) including at least one barrel system (2) for driving a set of wheels and power reserve detector. The detector (10) includes a control wheel (3) disposed opposite the cage of the barrel system (2) and is rotated by a complementary wheel (8) at the differential output to determine a power reserve level. An aperture (13) has a first end (21) to define a complete charge of the barrel system and a second end (22) to define a complete discharge. A lever (4) is rotatably mounted about a lever axis parallel to the axis of rotation of the control wheel. A contact element (5) disposed in the aperture contacts the second end during a zero power reserve indication. A portion of the lever contacts a component of the movement to stop its operation when power reserve indication is at zero.

System and method for determining at least one parameter relating to an angular movement of an arbor

A system and method to determine angular movement of an arbor integral with a crown of a watch, the arbor being rotatable on itself in a longitudinal direction. The system includes a rotating reflector mounted on the arbor, and two emitter/detector pairs disposed on either side of the reflector, each including 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 determines a parameter relating to the angular movement of the arbor. The rotating reflector is a cylinder of revolution and light absorption points are made on the circumference of an external cylindrical surface. When the reflector rotates in a regular manner and in the same direction of rotation, the representative electrical signal generated by each detector has a sinusoidal shape.
