摘要： The film (10) has light-controlling microstructures (12) i.e. linear structures, formed in the film and provided parallel to each other. A safety feature e.g. portrait image, is formed in the microstructures. The film is transparent in a primary view angle (14). The safety feature is designed not visible when the film is viewed in a false view angle, and visible when the film is viewed in a correct view angle (22) or a range of view angles. The correct view angle or the range of view angles is obtained, in which the film is rotated around an axis perpendicular to a surface of the film. Independent claims are also included for the following: (1) a document (2) a method for producing a safety feature in a light control film.

摘要： The aim of the invention is a method, whereby the least energy per pulse required is achieved, despite high pulse frequencies, during the machining of materials by means of laser beams (2a, 2b, 2c), in particular during the engraving of, for example, metal, or during the blackening and inscribing of plastics. Said aim is achieved, whereby several laser beams (2a, 2b, 2c) are brought together, by means of a beam combiner (5, 5a, 5b), fed down a common beam guide onto the workpiece and, in particular, controlled in an intermittent manner.

摘要： The present invention concerns a system for the calibration of at least one parameter of a laser engraver, the laser engraver comprising on one hand an engraving system with a focusing lens positioned at a distance of the surface of an substrate intended to be engraved and on the other hand a vision system for at least the positioning and the verification of the engraving, the vision system including a camera associated with an appropriate illumination and, wherein the engraving device of the laser is arranged in such way that the engraving device works to engrave a substrate with specific engraved layout corresponding to variation of at least one parameter and wherein the vision system is connected to a comparison device of at least one measured engraved parameter with the template value of at least one stored data in a memorization device connected to a engraving correction device.

摘要： An object processing machine for processing a plurality of objects, the machine comprising: a plurality of processing modules, each processing module having a modular structure co-operable with the modular structure of another processing module to form a modular assembly constituting the object processing machine; each processing module being operable to perform a corresponding processing operation on an object and being provided with at least one transfer unit located at a respective port of the processing module; each transfer unit being arranged to transfer an object to or from the corresponding processing module and/or to or from a transfer unit of another processing module of the modular assembly; the transfer units being arranged to co-operate with one another and/or with another processing unit such that objects can be guided from an input of the machine to an output of the machine via a plurality of different transport pathways through the machine, wherein the transport pathway taken by a said object being processed corresponds to the pre-determined processing operations to be performed on the said object. A method of processing a plurality of objects using such a machine is also described.
