Abstract: The invention relates to the field of management systems and methods of an active device and more particularly, with said active device being an active ophthalmic lens, to a management system and method which allow a total or sufficient protection by taking into account the luminous environment of the wearer while avoiding some effects relative to permanent light filtering. According to a particular embodiment of the invention, there is also provided a monitoring of the wearer's health via active, regulated and continuous control of the active device, this control being performed for instance by a health professional via a remote monitoring system.

Abstract: A method cuts a patch to be applied onto a curved substrate and includes the preliminary calculation of curvilinear lengths on the substrate between a reference point and a peripheral edge of said substrate. The calculated lengths are applied to a planar film for making the patch, and then the patch is cut by connecting the ends of the applied lengths. The patch then precisely coincides with the edge of the substrate. Such a method is particularly useful for applying a functional film onto a spectacle lens, as a trimming of the lens after the film is assembled with the lens would degrade said film.

Abstract: An imaging device including an illumination module including at least one emitter for emitting at least one excitation beam, a scanning and injection module including an image guide, a proximal end and a distal end of which are linked by a plurality of optical fibers, and a scanning and injection optical system configured to alternately inject the at least one excitation beam into an optical fiber of the image guide from the proximal end of the image guide, and a detection module including at least one detector for detecting at least one luminous flux collected at the distal end of the image guide. At least one of the illumination module and the detection module is optically conjugated with the scanning and injection module by a conjugating optical fiber.

Abstract: A method of transferring a portion of a functional film (1) onto a substrate from a base plate (100) comprises the formation of a groove (S1) which passes through the said functional film and also a separating film (2) placed between the functional film and the base plate. A portion (2p) of the separating film is then detached from the base plate with the portion of the functional film. The portion of said separating film protects the portion of the functional film in the rest of the method. According to one improvement, the portion of the functional film which is detached from the base plate comprises a useful portion (1p) and a margin (1m) that are connected together by the portion (2p) of the separating film. The useful portion (1p) of the functional film may then be gripped and handled via the margin (1m).

Abstract: A miniaturized optical head provided to equip the distal end of a beam of flexible optical fibers scanned by a laser beam, is designed to come in contact with a sample and to excite the sample confocally. This optical head includes elements for correcting spherical aberrations and focusing members. The focusing members include: at least a first lens (L4) of high convergence associated with a spherical or hemispherical lens (L5) arranged at the distal end of the optical head, and elements for correcting the axial and lateral chromatic aberration provided with a single divergent lens (3b) whose curvature is substantially centered on the pupil of the optical fiber beam and arranged at the exact distance for this pupil for which the conditions of lateral achromatization coincide with the conditions of axial achromatization; this divergent lens being associated with a second convergent lens (L3a) in the form of a doublet (L3).
