Abstract: The invention relates to an actuator comprising at least one epicyclic gear stage (28, 28.1, 28.2), and including an angular position sensor (42) comprising a target (46) mounted in a secured manner on a connecting rod (52) which is secured in rotation to a output mechanical connector (24) of the actuator (10), characterized in that the input component of the epicyclic gear stage is guided in rotation on the connecting rod (52) with a first positive diametrical guide clearance (“jg1”) relative to the main axis (A2), in that the output component of the epicyclic gear stage is rigidly connected to the connecting rod (52), and in that a rotatable assembly of the epicyclic gear stage (28) is positioned relative to the actuator casing (12) with a diametrical displacement clearance (“jd”) which is at least 3 times greater than the first diametrical guide clearance (“jg1”).

Abstract: Disclosed is a centering apparatus including: a chassis; a holder mounted on the chassis, which is suitable for receiving an ophthalmic lens; and a centering unit mounted on the chassis, which includes: a camera for acquiring images of the ophthalmic lens when received on the holder, and a screen for displaying the images acquired by the camera and a centering target superimposed onto the images, the centering target including two coaxial and parallel outlines.

Abstract: A system for monitoring the position of a blocking device on an ophthalmic lens (20) having at least one marking comprises: —a mechanical structure adapted to cooperate with the blocking device; —an image sensor (4) observing the ophthalmic lens (20); —a control unit (10) connected to the image sensor (4) and configured to produce an image having a point of reference with a determined position with respect to the mechanical structure and at least part of the ophthalmic lens (20) including said marking; and—a user interface (12) adapted to display a blocking device positional compensation proposal for an automatic positional compensation or for a manual positional compensation based on the comparison to a predetermined threshold of a distance between the point of reference and the marking on the image. A corresponding method and a method for edging an ophthalmic lens are also proposed.

Abstract: The method includes the steps of: providing spectacles including a template eyeglass having a mounting portion inserted in a groove of an arc and being to be replaced by a prescription eyeglass having a step-back portion with the same conformation as the mounting portion; providing a set of visible marks on the template eyeglass independently of the arc; having an outline editor providing a visualization of the template eyeglass provided with the visible marks; determining through observation of the spectacles the location—with respect to the visible marks—of points of the arc from which the template eyeglass projects; entering on the provided visualization the so determined locations of the points of the arc; and outputting from the editor the data representative of an edited outline based on the point locations so entered on the provided visualization, whereby the edited outline is the outline of the shoulder.

Abstract: The invention proposes an actuator for a component of a land motor vehicle, of the type including an actuator casing (12) which is produced by injection molding of thermoplastic polymer material and which delimits an internal volume in which are arranged: at least one electric motor (16), and an internal mechanical transmission (18) comprising at least a first gear wheel (24), which has an axis of rotation (A2) perpendicular to the axis of rotation (A1) of the drive shaft (20), characterized in that the first gear wheel (24) has a toothing (28), called axial toothing, which is formed of gear teeth having a bottom-top extension according to the direction of the axis of rotation (A2) of the first gear wheel (24), and which meshes with the output pinion (22) of the electric motor (16).

Abstract: A device and process for determining the dominant eye of a patient (10), wherein the device includes a target (120), a camera (110) for acquiring an image of the patient's face, and a mask (200) to be positioned in front of the patient's face. The mask includes; a closure face (210) suitable for hiding the target from the patient while enabling the camera to see the patient's face, and a viewing window (220) for the patient to view the target and which is located through the closure face in order to enable the patient to view the target with only one of his two eyes.

Abstract: The invention relates to a method for obtaining images from slices of a specimen, the method comprising: repeatedly obtaining an image of the surface layer of the specimen (1) and removing the surface layer of the specimen, thereby bringing the next slice to the surface; characterized in that after at least one of the removals of a surface layer the specimen is exposed to a staining agent. This method is especially suited for use in a particle-optical instrument equipped with both a scanning electron microscope column (20) and a focused ion beam column (10). The specimen can e.g. be stained in situ by admitting a gas, such as OsO4 (osmiumtetroxide), to the specimen. This method also makes it possible to perform differential staining by first making an image of the specimen exposed to a first staining agent, and subsequently making an image of the specimen when it is additionally stained by a second staining agent.
