Abstract: The present invention concerns a method of controlling a rotational speed of a rotor (3) of a direct current electric motor (1) comprising an inductor circuit (A, B) for rotating the rotor, which is configured to rotate continuously and is equipped with permanent magnets. The method comprises: measuring the rotational speed of the rotor; determining a time drift in the rotor rotation compared to a reference signal; defining N speed thresholds with at least one being a variable speed threshold depending on the determined time drift, the N speed thresholds defining N+1 rotational speed ranges for the rotor; determining in which one of the N+1 rotational speed ranges the determined rotational speed of the rotor is; and finally selecting an action relative to the control of the inductor circuit, based on the determined rotational speed range, for controlling the rotational speed of the rotor.

Abstract: A method for single or multiply charged ion implantation into a surface of a treated object, and a device for implementing the implantation method, the method including: directing towards the surface of the treated object an ion beam produced by an ion source of the electronic cyclotron resonance type; producing at least one primary electron beam and directing the primary electron beam so that it passes through the ion beam; and producing a secondary electron beam by reflecting the primary electron beam onto a target once the primary electron beam has traversed the ion beam, the target being oriented such that the secondary electron beam falls onto the surface of the treated object.

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 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.
