Patent number: 11925435Abstract: An intra-oral scanning device includes a light source and an optical system, and communicates with a display system. The device provides for more efficient transmission and capture of images. It integrates OCT scanning with RGB-based scanning. In operation, the device is used for recording topological characteristics of teeth, dental impressions, or stone models by digital methods and for use in CAD/CAM of dental restorative prosthetic devices. To that end, the RGB-based scan obtains surface data (e.g., a margin), while the OCT scan penetrates the surface. The two scanners operate from within the same physical housing and preferably at the same time such that only one scanning pass (to obtain all necessary data) is required. The 3D data obtained from the OCT scan is registered with the 3D data obtained from the RGB-based scan by virtue of being captured using a common return path.Type: GrantFiled: June 9, 2022Date of Patent: March 12, 2024Assignee: D4D Technologies, LLCInventors: Ye Li, Justin G. Graham, Rod A. Duncan, Greg R. Basile, Grant E. Kenworthy, Henley S. Quadling, Mark S. Quadling, Glen Freeman

Patent number: 9347973Abstract: A stress control apparatus for managing effects caused by electrical stress in a high voltage environment, and methods of manufacturing the apparatus. A dielectric tube with a central bore coated with a conductive material has an outer conductive coating on a lower section that is grounded. The central bore carries a high voltage potential from a current-carrying conductor. The grounded coating transitions to the exposed outer dielectric surface along a gradually tapered transition. A conductive insert connects to the central bore and forms an electric field in a space between the insert and the grounded coating. When coated with an epoxy and inserted into the central bore, the insert forms a small gap between an outer surface of the insert and part of the central bore, such that there is no zero potential difference in the gap. Any epoxy that oozes out during insertion will collect in the gap.Type: GrantFiled: May 15, 2014Date of Patent: May 24, 2016Assignee: Gridview Optical Solutions, LLCInventors: Philip B. Davis, Edward B. Condon, Grant E. Kenworthy
