  • Patent number: 11029664
    Abstract: Methods and corresponding systems that are useful in design and fabrication of kinetic wire mechanisms or characters. The method includes a computational technique for the design of kinetic wire mechanisms tailored for fabrication on consumer-grade hardware such as a desktop CNC bending device. The method takes as input a skeletal animation of the mechanism to be fabricated and estimates, from the skeletal animation, a cable-driven and compliant wire structure, which matches user-selected keyframes. To enable localized deformations, the technique involves shaping the mechanism's body (i.e., the wire) into functional spring-like entities at a set of locations along the length of the mechanism's body.

  • Patent number: 11013582
    Abstract: A method and system generate a scan model that is a mathematical model to simulate an imaging process performed by an x-ray imaging device that created a two-dimensional x-ray image of at least one tooth. The scan model uses an initial estimate of one or more parameters of the x-ray imaging device to simulate the imaging process on a three-dimensional model. The method and system generate the two-dimensional contour of the three-dimensional model based on the scan model that uses the initial estimate of the one or more parameters of the x-ray imaging device. The method and system adjust the two-dimensional contour to cause a first component of the two-dimensional contour to approximately align with a second component of the two-dimensional x-ray image. The method and system calibrate the scan model based on data obtained from adjusting the two-dimensional contour.

  • Patent number: 10842594
    Abstract: A system and associated methodology for the generation of digital models that account for the adaptation of the shape of the patient's gingiva is provided. The exemplary system uses an initial scan of the patient's gingiva as a base model, taking into account the type and morphology of the teeth, the shape, orientation and movements of the roots inside the gingiva, and other factors for a more accurate prediction of the changes in the shape of the gingiva throughout every step of the treatment. In particular, the system proactively determines the areas of the model that will be covered by the aligner and prevents changes to such areas, whereas the shape of the model outside these areas is altered in a way to minimize the size of model and to add any necessary features for the manufacturing of the aligners.

  • Patent number: 10839481
    Abstract: The invention aligns a digital face model from a 3D face scanner with a 3D jaw scan from an intraoral scan produced by an intraoral scanner without using external markers. The alignment proceeds in two steps. In the first step, the teeth part of a subject whose teeth are clenched, referred to as a clenched-teeth face scan, is aligned with an intraoral jaw scan to obtain a first transformation matrix. In the second step, a face model of a subject with a normal facial expression is aligned with the clenched-teeth face model of the same subject to obtain a second transformation matrix. A graphical user interface is provided that enables a user to manually align the 3D jaw scan with a 2D image of the subject's teeth to determine the first transformation.
