  • Patent number: 11768983
    Abstract: The present invention generally relates to a method, a system and a computer program for shape optimisation of a technical device adapted to be exposed to a fluid flowing around a contour of said device with respect to its fluid dynamic parameters. In order to provide an improved method for shape optimisation of a technical device with respect to its fluid dynamic parameters which is faster, a method is provided comprising discretizing the shape of the technical device into a plurality of points along the contour of the technical device or into a surface mesh, and inputting the plurality of points or the surface mesh into a Convolutional Neural Network (CNN) for computing a prediction of the at least one fluid dynamic parameter.

  • Publication number: 20230157578
    Abstract: An analysis method for analyzing pressure exerted by a body portion and/or of a human prosthesis includes: sampling data generated by the body portion and/or the prosthesis during a threshold calibration period at a sampling frequency in a condition of use thereby obtaining an array of sampled data of at least one sensing unit; providing at least one threshold value of the sampled data for the condition of use and storing the least one threshold value in a memory unit; comparing at the sampling frequency the sampled data with the at least one threshold value to obtain calibrated data, and storing the calibrated data in the memory unit and/or sending the calibrated data to a computing device if the calibrated data is greater than the at least one threshold value. A sensing device for sensing the pressure exerted by a body portion and/or the human prosthesis is also provided.

  • Patent number: 10787576
    Abstract: The invention relates to a method for the preparation of a coating comprising at least one coating layer on a substrate, the method comprising the steps of a. providing monomers of the type R—(N)x-(L)m-(C?C)n-(L?)o-(N?)y—R?, wherein R is a head moiety, R? is a tail moiety, (C?C)n is an oligoyne moiety, L and L? are linker moieties, N and N? independently are branched or unbranched optionally substituted C1-C25 alkyl moieties optionally containing 1 to 5 heteroatoms, x, m, o, and y are independently 0 or 1, n is 4 to 12, and wherein the head moiety allows for an interaction with the surface of the substrate; b. bringing the monomers into contact with the substrate wherein the interaction of the head moieties of the monomers with the surface of the substrate induces at least a part of the monomers to align in a defined manner thereby forming a film on the surface and bringing the oligoyne moieties of the monomers into close contact with each other; c.

  • Patent number: 9437753
    Abstract: A device includes a conductive surface (12) and electrical contacts (14) by which an electric current is able to be passed. The electrical contacts (14) include conductive seeds (16) deposited on the conductive surface (12), an electrically insulating layer (18), which covers discontinuously the conductive seeds (16) in order to form openings leaving access to the conductive seeds (16), and a plating layer (22) recovering the discontinuous insulating layer (18) and deposited on conductive seeds (16) which are accessible through the openings and form points from which the deposit of the plating layer (22) can start. The rest of the conductive surface (12), which doesn't include any electrical contacts (14), is continuously covered by the electrically insulating layer (18).

  • Patent number: 9324505
    Abstract: The invention relates to substituted ullazine and analogs of ullazine as sensitizers for dye-sensitized solar cells (DSSCs) and other photoelectrochemical and/or optoelectronic devices. The sensitizers may comprise donor substituents and/or acceptor substituents, besides an anchoring group suitable for attaching the sensitizer on a semiconductor surface. DSSCs based on this type of sensitizers exhibit high power conversion efficiencies.

  • Patent number: 9086465
    Abstract: A method for high resolution NMR (=nuclear magnetic resonance) measurements using the application of excitation pulses and the acquisition of data points, whereby a dwell time ?t separates the acquisition of two consecutive data points, which is characterized in that one or more tickling rf (=radio frequency) pulses of duration ?p are applied within each dwell time ?t, and that the average rf field amplitude of each of the tickling rf pulses approximately fulfills the condition ?1=?1?p/?t=?J wherein J is the scalar J-coupling constant and ?1=?B1 with ? being the gyromagnetic ratio and B1 being the strength of the magnetic component of each tickling rf pulse. This method is effective in decoupling homonuclear couplings.

  • Publication number: 20130311868
    Abstract: A computerized method for annotating at least one feature of an image of a view, includes the steps of obtaining the image with an image sensor of a portable device, and retrieving at least one condition. Based on the at least one condition, the method automatically selects a feature identification method among a plurality of features identification methods. It then applies the feature identification method for identifying the at least one feature, and annotates some of the identified features.
