  • Publication number: 20200015948
    Abstract: Disclosed is a method for determining the relative arrangement of patient's jaws in a bite position when the patient's occlusion is not defined by natural teeth alone, where the method includes a step of obtaining a digital 3D representation including both surface data relating to dental tissue in one of the patient's jaws and surface data relating to a scan appliance arranged in relation to the jaw, where the scan appliance is configured for at least partly defining the patient's occlusion.

  • Publication number: 20190267616
    Abstract: The present disclosure relates generally to an electrode produced with a non-toxic solvent, resulting in a homogeneous mixture with uniform distributions of a conductive additive and a binder. Electrodes produced according to the present disclosure feature narrow binder particle size distribution, which distinguishes such electrodes from typical electrodes produced via a N-Methyl-Pyrrolidone (NMP) process. The resulting microstructure promotes the flow of current through the electrode and has an improved cycling stability due, in part, to the binder's and the conductive additive's ability to bind with the active material particles used in the fabrication of the electrode.

  • Patent number: 10010387
    Abstract: A method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation includes shape data and texture data for the tooth is obtained. A tooth shade value for at least one point on the tooth is determined based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.

  • Patent number: 8833043
    Abstract: The present invention relates to a row of lids (1) defining an unbroken sheet material having a longitudinal direction, the sheet material being shaped so that the rim of the sheet material defines first rims section (3) of the lids (2) and so that second rims sections (4) of two lids (2) being adjacent to each other in the row of lids are defined by one cut in a direction being different from perpendicular to the longitudinal direction (5) of the sheet material.

  • Patent number: 8724198
    Abstract: The present invention is generally related to the field of optical systems and/or lens attachments, and more specific to an optical system and/or lens attachment providing a switchable Optical Power Switch (OPS) controllably switchable between different states. A soft transparent material (12), for example silicone-gel is disposed onto a surface of a glass plate (10). The glass plate (10) can be moved with actuators towards a surface of a lens body (10). When the soft material element (12) is in contact with the surface of the lens body (12), this surface changes its optical feature.

  • Patent number: 8310772
    Abstract: The present invention provides thermal compensation for a lens assembly comprising a polymer lens body. Polymers do have different thermal expansion coefficients which makes it necessary to compensate for thermal expansions to keep optical characteristics of such lenses within specifications when used under different environmental conditions. Also, it is necessary to provide thermal compensation during manufacturing of such lenses due to high temperatures during manufacturing steps.
