Abstract: An active lighting device of a bicycle includes a first optical system with a first light source arrangement for long-distance illumination, which is controlled by a control unit, and a second optical system with a second light source arrangement for short-distance illumination, which is controlled by the control unit. A light sensor determines the light intensity of a location of the bicycle and allows the control unit to adapt the light intensity of the light sources, if they are activated and if the ambient light intensity is below a threshold. A speed sensor determines the speed of the bicycle, so that the control unit controls the activation of the light sources of the first light source arrangement from a speed threshold. An orientation or inclination detector selects and adjusts the light intensity of light sources.

It includes a light sensor for determining the light intensity of a location in which the bicycle is situated and allows the control unit to adapt the light intensity of the light sources, if they are activated and if the ambient light intensity is below a determined light threshold. Moreover, a speed sensor is provided for determining the speed of the bicycle in use on a path, so that the control unit controls the activation of the first light source from at least one determined speed threshold. An orientation detector is provided for orienting the light sources depending on a curve travelled by the bicycle in use.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An oscillator includes a resonator, which has an inertial mass returned by an elastic return and carries entry and exit pallets cooperating with teeth of an escape wheel each provided with a magnet. Each pallet includes a magnetic arrangement, with an annular sector, centred on the axis of oscillation of the resonator, defining a first magnetic barrier area extending above and/or below a mechanical pallet-stone of the entry pallet or exit pallet, over the entire length of this mechanical pallet-stone acting as support for the teeth during the supplementary arc, in order to form a magnetic cylinder escapement mechanism.

Abstract: 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.
