| There is provided a device for regulating the operation of a horological movement, including a magnetic escapement, which includes a resonator and a magnetic escapement mobile turning about an axis. The mobile includes at least one magnetic track with a plurality of magnets having an angular dimension that is greater than their radial dimension. The resonator includes at least one magnetic element for coupling to the magnetic track. The coupling element extends radially relative to the axis of rotation, and has a contour with a portion oriented substantially angularly when the resonator is in the rest position. When the mobile is driven in rotation, each magnet penetrates beneath the coupling element and gradually accumulates some potential magnetic energy. The magnet then exits from beneath the coupling element through the portion and the coupling element receives a pulse located around its rest position. | ||||||

| An object of this invention is to sense a transient displacement of the blade position to thereby detect abnormalities early. The invention includes: one or more first sensors mounted so as to be removable from an outer surface of a casing opposed to blade tips; a second sensor for acquiring a signal from a fixed point on a rotor shaft of the blades; a section configured to extract data groups from an output signal of the first sensor on the basis of information acquired by the second sensor; a section configured to average the data groups; a section configured to determine thresholds from averaged data obtained under a healthy condition; and an assessing section configured to compare magnitude of the thresholds and sensor signals obtained during blade status monitoring. Since a transient displacement of blade position can be sensed, abnormalities can be detected early in this invention. This early detection, in turn, enables a rotation to be stopped during an initial phase of blade damage. The invention is therefore advantageous in minimizing impacts on other devices. | ||||||

| 230 | REGULATING SYSTEM FOR A MECHANICAL WATCH | US14784175 | 2014-07-22 | US20160070235A1 | 2016-03-10 | Jean-Pierre MIGNOT; Jean-Jacques BORN; Rudolf DINGER |
| Regulating members for a mechanical timepiece, specifically a system based on magnetic interaction between a resonator, in a form of a tuning fork for example, and an escape wheel, as a magnetic escapement. In the system plural areas of magnetic interaction between the resonator and the escape wheel are arranged such that torques produced at the escape wheel by the interactions compensate each other if the escape wheel is not synchronized at the frequency of the resonator. This results in negligible torque in the escape wheel when the escape wheel rotates slowly in a direction of an arrow or opposite direction. This allows the timepiece to start with a low mainspring torque and without any start procedure or device and provides better resistance of the timepiece against a loss of synchronization in event of a shock. | ||||||
