Abstract: 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.

Abstract: A personal identification system for children that includes two forms of identification. An identification card carried by the user contains the user's personal and medical information in an electronic medium. The identification card includes photographs of the user and their parent or legal guardian, a unique identification number for the user, and a list of corporate sponsors. The second identification device is to be worn by the user and includes the user's unique identification number and an access telephone number. A user interface enables the users to update their stored personal and medical information.
