  • Patent number: 11425277
    Abstract: A method for manufacturing decorative panels includes rendering a wood pattern on a paper with a marking device to form a decorative layer before resin impregnation and heat pressing, wherein the marking device includes M inks and N inkjet printhead units. The rendering is performed in a plurality of passes in which each inkjet printhead unit includes the M inks, and the rendering step includes generating N sub-images in which an intensity of each pixel in the wood pattern equals the sum of intensities of corresponding pixels from the N sub-images, and the intensity of a pixel from a first sub-image from the N sub-images is a first percentage between 1 and 99 of the intensity of corresponding pixel in the wood pattern, and the intensity of a corresponding pixel from a second sub-image from the N sub-images is a second percentage between 1 and 99 of the intensity of corresponding pixel in the wood pattern.

  • Patent number: 11243214
    Abstract: The present invention is directed to the identification of a biomarker specifically located in the plasma membrane of pancreatic beta cells. Based on a set of specific features the biomarker is a unique candidate for imaging and targeting strategies to study the pancreatic beta cell mass in health and disease (T1D, T2D, pancreatic cancers, obesity, islet transplantation, beta cell regeneration).

  • Patent number: 10500875
    Abstract: An inkjet printing method using an inkjet printing device including a vacuum support for a substrate held down against a support surface of the vacuum support by air suction includes a step of jetting a set of layers with a set of liquids on the support surface to form a pattern with a surface roughness between 2.0 ?m and 200.0 ?m and rougher than the surface roughness of the support surface, and a step of supporting the substrate at least partially on the pattern.

  • Publication number: 20100330049
    Abstract: The present invention relates to an in vitro method for generating insulin-producing beta cells from a population of mammalian cells comprising dedifferentiated exocrine pancreatic cells. The method comprises the step of culturing said dedifferentiated exocrine pancreatic cells in a culture medium in the presence of at least one agent that is able to inhibit the Notch 1 signaling pathway in said dedifferentiated exocrine pancreatic cells, and at least one ligand of the gp130 receptor and/or at least one ligand of the EGF receptor. The invention further provides a population of mammalian pancreatic cells comprising insulin-producing beta cells obtainable by the present method and uses thereof in a pharmaceutical composition for treating type 1 or type 2 diabetes.

  • Patent number: 7365720
    Abstract: A calibration method for calibrating a fixed format emissive display device having a plurality of pixels is described In the display each pixel comprises at least three sub-pixels for emitting light of different real primary colours. The method comprises determining, for each real primary colour separately, a virtual target primary colour which can be reached by at least 80% of the pixels of the display, determining a colour gamut defined by the determined virtual target primary colours, and adjusting the drive currents to the sub-pixels to achieve a colour inside the determined colour gamut. A display having an extended range of colours is described, i.e. a gamut of colours that is more than the gamut provided by an n virtual primary colour based electronic multicolour display, as measured on a chromaticity diagram, for example. A color and/or brightness uniform image can be produced with this fixed format emissive display device.
