  • Patent number: 12068074
    Abstract: A stereoscopic marker device includes: a polyhedral cube, including at least four flat surfaces, wherein the at least four flat surfaces are used as one primary marker and at least three secondary markers respectively, the primary marker includes a primary graphic code, the three secondary markers individually include a first secondary graphic code, a second secondary graphic code, and a third secondary graphic code, and the primary graphic code is used for providing spatial coordinate information, which is used for calculating six degrees of freedom (DOF) attitude data; and a spike-shaped body, combined with the polyhedral cube and configured to be fixed on a surgery site.
    Type: Grant

  • Publication number: 20210153747
    Abstract: A mobile device for detecting an oral pathology includes a casing, a probing unit, and a processor. The probing unit includes a fiber bundle set and a contact part configured to contact a gum portion of a tooth of an examinate. The fiber bundle set includes a light source fiber bundle and a light-receiving fiber bundle. The light source fiber bundle has a light-exiting end within the contact part, and can project a probing light onto the gum portion. The light-receiving fiber bundle has a light-receiving end within the contact part. The light-receiving fiber bundle can receive diffuse reflection lights generated after the probing light is diffuse reflected by the gum portion. The processor is in signal connection with the light-receiving fiber bundle, and can receive the diffuse reflection lights, to build an optical spectrum, and to determine a state of the gum portion according to the optical spectrum.
