Abstract: A timepiece mechanism including a first component and a second component configured to cooperate with each other in a relative motion on a trajectory in an interface area, wherein a first path of the first component includes magnetic and/or electrostatic actuation components, configured to exert a contactless stress on complementary magnetic and/or electrostatic actuation components included in a second path belonging to the second component. Throughout a monotonous relative movement of the second path with respect to the first path, interaction energy between the first component and second component has a variable gradient with at least one position of discontinuity of the gradient, which corresponds to a variation in the contactless stress, the position of discontinuity of the gradient corresponding, in a variant, to an abrupt variation in the contactless stress.

Abstract: A timepiece resonator mechanism includes a structure and an inertial element oscillating around an axis and subjected to restoring forces exerted by a plurality of elastic blades, each fixed directly or indirectly to the structure at a first end and fixed directly or indirectly to an inertial element at a second end. The elastic blade extends in a perpendicular plane to the pivot axis and is deformable substantially in this plane, where this resonator mechanism includes an axial stop including at least a lower axial stop and/or an upper axial stop, and the axial stop is arranged for the protection of the blade resonator mechanism against axial shocks in the direction of the axis.

Abstract: The invention concerns a device for regulating the relative angular speed between a magnetic structure and a resonator magnetically coupled to each other and forming an oscillator which defines a magnetic escapement. The magnetic structure includes at least one annular magnetic path at least partially formed of a magnetic material and the resonator includes at least one element for magnetic coupling to the annular magnetic path, this coupling element being formed of a magnetic material having a physical parameter correlated to the magnetic potential energy of the oscillator. The radial dimension of the annular magnetic path is smaller than a corresponding dimension of the coupling element, and the magnetic material is arranged so that the physical parameter of said magnetic material gradually increases angularly or gradually decreases angularly in order to obtain an angularly extended magnetic potential energy area in each angular period of the annular magnetic path.

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.
