摘要： An active lighting device is placed on a person's wrist to light a path that the person is taking. The device is preferably in the form of a wristwatch. The device includes first light sources, which are controlled by a control unit. The first light sources are placed on a portion of a case. Each first light source activated by the control unit can produce a light beam of different orientation from another first light source activated by the control unit. The device further includes a motion sensor connected to the control unit to determine the wrist movement of the person wearing the device in order to allow the control unit to select certain first light sources to be activated depending on the person's wrist movement in order to light the path to be followed in the same defined forward direction.

摘要： A timepiece movement, including a mechanism including an inertial element arranged to oscillate or pivot about a first axis of pivoting relative to a structure of the movement, and arranged to cooperate directly or indirectly with an energy distribution wheel set that pivots relative to the structure about a second axis of pivoting parallel to or coincident with the first axis of pivoting and subjected to a torque exerted by an energy source, wherein the energy distribution wheel set meshes directly or indirectly with at least one inertia wheel set that pivots about a third axis of pivoting relative to the structure, each inertia wheel set is arranged to pivot in the opposite direction to the energy distribution wheel set, and the total inertia of the inertia wheel sets is comprised between 60% and 140% of the inertia of the energy distribution wheel set.

摘要： A horological movement provided with a generator and a circuit for regulating the frequency of rotation of this generator, the regulation circuit being arranged to be able to detect the zero crossings of an induced voltage generated in the stator by the rotating rotor and to generate first braking pulses which are triggered after zero crossings and each end before the induced voltage reaches a peak value, preferably before the rectified induced voltage reaches a power supply voltage provided by a power supply capacity. In addition, the regulation circuit is arranged so as to be able to further generate second braking pulses each of which occurs after detection of the end of a charging period of the power supply capacity during which the induced voltage reaches a peak value and each end before the induced voltage crosses zero.

摘要： A method for manufacturing a plurality of generators, each intended to power supply an electronic circuit operating in a given power supply voltage range, includes a step of manufacturing coils distributed in N pluralities of coils, similar within the same plurality and different from one plurality to another, and a step of manufacturing a plurality of rotors which is carried out with tolerances limiting the cost of production. The plurality of rotors is classified into N classes of rotors which are associated respectively with the N pluralities of coils to form N pairs allowing the assembly of N groups of generators. The generators of each of the N groups of generators have magnetic coupling factors between their rotor and their stator which are located in a corresponding optimised value range, which is at least partially superimposed on the others of the N optimised value ranges relating to the N generator groups.

摘要： A timepiece and method for mounting a generator in the timepiece, this generator being formed of a rotor with permanent magnets and two coils. A supporting structure is preassembled with the rotor and an electronic module including the two coils is preformed. The method includes the following successive steps for laterally mounting the electronic module in the supporting structure so as to form the generator; assembly of an electronic module support with the supporting structure to form an articulation; rotation of the electronic module thanks to the articulation to bring the two coils closer to the axis of rotation of the rotor, so that these two coils are finally each located in a functional position at the same distance from the axis of rotation of the rotor; fastening of the electronic module to block the articulation after said rotation and thus maintain this electronic module in a functional angular position.

摘要： A mechanical timepiece oscillator includes, between a support and an inertial element, a flexure bearing with flexible strips crossed in projection, including, superposed, an upper level that includes, between an upper support and an upper inertial element, an upper primary strip in a first direction and an upper secondary strip in a second direction, and a lower level that includes, between a lower support and a lower inertial element, a lower primary strip in the first direction and a lower secondary strip in the second direction. The upper level and lower level include, between the support and the upper or respectively lower support, a translational table with an elastic connection along one or two axes of freedom in the oscillation plane, of lower stiffness than that of each flexible strip.

摘要： A method for making a flexure bearing for an oscillator with an inertial element oscillating in a plane supported by flexible strips fixed to a stationary support returning it to a rest position includes: forming the bearing with basic strips in superposed levels, each having an aspect ratio of less than 10; breaking down the number of basic levels into a plurality of sub-units, each including one or two strips joining a basic support and a basic inertial element, which are made by etching substrates; assembling the sub-units by joining their basic inertial elements; and fixing the basic supports to the support, directly or via translational tables along one or two in-plane translational degrees of freedom, of lower translational stiffness than that of the sub-unit.

摘要： Timepiece movement including a flexible strip resonator cooperating with a magnetic escapement mechanism, wherein an escape wheel set includes tangential magnetized areas repelling first magnetized areas of an inertial element of the resonator, this movement includes isochronism correction means combining the first magnetized areas and compensating magnets on the escape wheel set, each arranged in proximity to a tangential magnetized area and producing a leakage field in a different direction from that of the field of the tangential magnetized area, the leakage field intensity being low compared to that of the field of the second tangential magnetized area, and this leakage field interacting with one of the first magnetized areas to produce a low variation in the operation of the resonator mechanism.
