  • Patent number: 8986793
    Abstract: A method of producing a metal element of an electronic device on a substrate, including the steps of: forming a mixture of a material comprising metal atoms with a liquid, depositing the material from the liquid mixture onto a substrate, and then irradiating at least part of the deposited material with light to increase the electrical conductivity of the deposited material.

  • Patent number: 8845058
    Abstract: A printing machine includes a substrate and at least one printhead with at least two material deposition channels which are movable with respect to the substrate, wherein the printhead is mounted on a stage which allows rotation of the printhead around an axis perpendicular to the substrate and translation in a direction perpendicular to the print direction, and wherein during each print swath, the rotation angle and translation values of the printhead are varied in order to change the pitch and the lateral position in the direction perpendicular to the print direction of material deposited from the different deposition channels; and an algorithm which computes the required rotation angles and translation values for a given pattern of substrate distortion.

  • Patent number: 6576591
    Abstract: A coding scheme to identify the connections an optical fiber is to form in an optical assembly is provided. The coding scheme consists of a series of colors, typically four, provided along the fiber length. The combination of colors identifies the connection the fiber is to form. Colors are transferred to the optical fiber by sublimation of the dye at a relatively low temperature. The sublimed dye then diffuses into the outer coating of the optical fiber.
