The present invention is directed to a computer-implemented method for identifying if an object is a genuine or a counterfeited object, wherein the method uses a combination of output from a predictive machine learning model and from a genuineness detection algorithm. In particular, the invention relates to methods for identifying a counterfeited object.
A microfluidics system to maintain alive and control cell cultures such as neuronal cell cultures over an air-liquid interface is arranged to prevent the formation of air bubbles and liquid overflows in fully automated 24/7 operation over the mid-long term. A pumping device is adapted to push a liquid through an inlet (131) of the microfluidics channel (130), then through an area of the microfluidics channel that is under the air-liquid interface, then through an outlet (132) of the microfluidics channel, assisted with geometrical arrangements of the microfluidics channel outlet and optionally inlet placements relative to the porous membranes of the air-liquid interface. The pumping device may be programmed with different flow rates, flow directions, and flow durations according to cell culture features and events detected with a computer vision system and/or an electrophysiological signal processing system to automatically adapt the parameters of the pumping device to the current state of the cell culture (100) over the air-liquid interface.

COGNITIVE COMPUTING METHODS AND SYSTEMS BASED ON BIOLOGICAL NEURAL NETWORKS
A Biological Neural Network (BNN) core unit comprising a neural cell culture, an input stimulation unit, an output readout unit may be controlled through its various life cycles to provide data processing functionality. An automation system comprising an environmental and chemical controller unit adapted to operate with the BNN stimulation and readout data interfaces facilitates the monitoring and adaptation of the BNN core unit parameters. Pre-processing and post-processing of the BNN interface signals may further facilitate the training and reinforcement learning by the BNN. Multiple BNN core units may also be assembled together as a stack. The proposed system provides a BNN Operating System as a core component for a wetware server to receive, process and transmit data for different client applications without exposing the BNN core unit components to the client user while requiring significantly less energy than conventional silicon-based hardware and software information processing for high-level cognitive computing tasks.
A machine learning system may automatically produce classifier algorithms and configuration parameters by selecting them into a set of predetermined unitary algorithms and associated parametrization values. Multiple digital representations of input object items may be produced by varying the position and orientation of the object to be classified and/or of the sensor to capture a digital representation of the object, and/or by varying a physical environment parameter which changes the digital representation capture of the object by the sensor. A robot arm or a conveyor may vary the object and/or the sensor positions and orientations. The machine learning system may employ genetic programming to facilitate the production of classifiers suitable for the classification of multiple digital representations of input object items. The machine learning system may automatically generate reference template signals as configuration parameters for the unitary algorithms to facilitate the production of classifiers suitable for the classification of multiple digital representations of input object items.
New authentication features are proposed that are visible, can be authenticated with a mobile equipment and yet are challenging to counterfeit. In a possible embodiment, the surface of the authentication feature may have three-dimensional characteristics, which can be recognized by a handheld camera, such as a smartphone camera, while it cannot be easily reproduced by a simple scan and print procedure. In a further possible embodiment, at least two different viewpoints of the authentication feature may be acquired using a smartphone camera and the resulting images may be analyzed using the smartphone processor to identify the three-dimensional characteristics of the authentication feature. The manufacturing of the feature may be performed at a low cost by embossing the three dimensional structure on a surface. The authentication feature may be carried by a self-adhesive label or directly embedded on the product packaging.
G07D 7/00 - Vérification spécialement adaptée à la détermination de l’identité ou de l’authenticité de papiers de valeur ou pour discriminer ceux qui sont inacceptables, p.ex. qui ne correspondent pas à une monnaie
The present invention concerns the field of tacking and authenticating genuine products such as tablets or pills manufactured by compressing powder The purpose of this invention is to provide a method to recognize tablets or pills by authenticate elements, those elements being very difficult to reproduce for the counterfeiters. Accordingly, the present invention proposes a method to authenticate genuine tablets manufactured by compressing powder between a punch/die set comprising the steps of at an initial stage - creating a microstructure on the surface of at least one of the face of the punch/die set, - compressing the powder between the punch and the die, - acquiring at least one reference image of the face of the tablet for which the punch/die set contains microstructure, And at a later stage - acquiring at least one test image of a tablet to be authenticated which is supposed to contain microstructure, - computing a level of similarity by an electronic device between the test image and each of the reference image, - comparing the computed level with a threshold value so as to define if the acquired tablet is genuine.

The present application concerns the visual identification of materials or documents for tracking purpose. The invention proposes a method to automatically identify an object by the following steps : - digitally acquiring a two-dimensional image through sampling on a uniformly spaced orthogonal grid of at least one color component of an area of interest of its surface illuminated by a non-coherent light which location, resolution, imaging angle and lighting angle are optimized for a given image matching metric, - comparing the acquired image to stored digital images of the same area, such comparison including the steps of : o preprocessing the image, o flattening the image, o applying a rotation compensation procedure, o applying a translation compensation procedure, o masking the areas of interest o computing a metric according to a deterministic convergence behavior when the mean square error between the acquired and recorded image tends towards a constant, such metric being dependent on the acquired and stored image resolutions and enabling the identification from the recorded images of a matching set of images for a given object image, the metric and threshold having the property that the cardinality of said matching set converges towards singleton when the resolution increases.
G06K 9/00 - Méthodes ou dispositions pour la lecture ou la reconnaissance de caractères imprimés ou écrits ou pour la reconnaissance de formes, p.ex. d'empreintes digitales
The present invention aims to provide a simple and reliable security element into a document, which can be recognized without special equipment. This aim is achieved with a paper or paper-like document with a surface, the surface being provided at least in a partial area with a background layer, wherein at least part of the surface of the document is provided with a security element comprising a series of protuberant structures spaced at regular interval. The protuberant structure creates a relief than can be easily recognized while rubbing the document. Contrarily to watermarks or other stamps, the fact that the structure is spaced at regular interval allows the user to better detect it over random structures. Regular interval does not mean that the space between each protuberant structure is equal. Regular means that each structure has a similar width and each space between the structures has also a similar width.
The present application aims to propose a solution for embedding invisible mark suitable for very large production volumes. This is achieved by a method for applying an invisible mark on a media based on a pattern, and comprising the following steps: determining an area to apply this mark, applying a transparent or semi-transparent substance, on the media, said substance being modulated with the active dots to form the pattern by modifying the quantity of the substance at each active dot.
