Abstract: A method for manufacturing a flexible strip, including forming a plate of the required thickness with one or more micromachinable substrate wafers; affixing, on either side of the plate, an upper mask with an upper window and a lower mask with a lower window, of identical geometry; etching the plate, at least to mid-thickness, from the upper side of each upper etching window, and from the side of each lower etching window; removing the upper mask and the lower mask, to delimit a flexible strip having a height equal to the thickness of the plate, and whose edges are as-etched. A flexible strip made of micromachinable material, including, between two parallel upper and lower surfaces, two peripheral, tapered and reverse-tapered edge surfaces, for a flexible pivot, a resonator, a movement or a watch.

Abstract: The invention concerns a magnetic device for regulating the relative angular velocity of a wheel and of at least one magnetic dipole integral with an oscillating device. The wheel or the dipole is driven by a driving torque. The wheel includes a periodic, ferromagnetic pole path which alternates according to a center angle and the at least one dipole is arranged to permit magnetic coupling with the ferromagnetic path and oscillation of the dipole at the natural frequency of the oscillating element during the relative motion of the wheel and of the magnetic dipole to regulate the relative angular velocity. The wheel further includes an assembly to dissipate the kinetic energy of the at least one dipole when it moves away from the ferromagnetic path.

Abstract: The horological movement includes a mechanical resonator and an escapement including an escapement wheel, which has a plurality of teeth, and an anchor formed by a stick and two arms having respectively two mechanical pallets likely to come into contact, when the anchor is subject to an alternative movement, with any of the teeth according to the angular position of the escapement wheel. To avoid damage to the escapement during rocking of the anchor while the escapement wheel is positioned in an unfavourable angular position, the anchor is arranged, during the rocking of this anchor, to be able to bend being subjected to an elastic deformation. The anchor has an elastic capacity between each of the two mechanical pallets and a fork of the anchor, enabling it to absorb elastically, during the elastic deformation, a maximum mechanical energy that the mechanical resonator can have during the normal functioning of the horological movement.

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: 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.
