Abstract: The unique advantages of computer-controlled fabrication of a patient-specific orthotic device using an automated fabrication machine capable of following computer instructions to create 3D surface contours and new developments in non-invasive three-dimensional (3D) scanning have made it possible to acquire digital models of freeform surfaces such as the surface anatomy of the human body and to then fabricate such a patient-specific device with high precision. Such a patient-specific device brings significant improvement in patient-specific fit, comfort, and function of medical devices (and, in particular, to orthoses that require a close fit to the wearer's body to act effectively). The combination of these two technologies is ideally suited for the development of patient-specific orthotic devices. A patient specific ankle-foot orthotic device using this technology is disclosed. This exemplary device is used to help stabilize the ankle-foot region, for example, in patients with impaired gait.

Abstract: A surveillance system uses an image from an omni-directional camera to identify objects or events of interest on which a higher-resolution camera can be trained.

Abstract: A method of automatically recognizing a human face includes developing a three-dimensional model of a face; and generating a number of two-dimensional images based on the three-dimensional model. The generated two-dimensional images are then enrolled in a database and searched against an input image to identifying the face of the input image.

Abstract: A method of automatic human identification includes matching an image of a subject'so ear against a database of images of ears from identified people to identify the subject.

Abstract: A computer automated 3D sketch artist process for generating a computer 3D image of an individual includes the steps of generating a morphable head model as a starting point to develop a composite 3D like picture of the individual by analysis of a prerecorded data base of 3D face pictures, selecting a lighting model to best depict the individual, selecting a mouth model from a prerecorded data base of mouth shapes to best depict the individual's mouth and teeth, selecting an expression model for the individual's composite 3D sketch from a prerecorded data base of facial expressions, and manipulating the generated composite 3D sketch with various morphing tools to selectively modify the composite sketch to best conform to the individual's characteristics.

Abstract: The present specification describes systems and methods for interactive three-dimensional dental imaging. More specifically, the present methods and systems provide for interactive computer-aided design (CAD) in dental applications. According to one of many possible embodiments, an interactive dental computer-aided design (CAD) system includes a graphical user interface for displaying at least one three-dimensional (3D) image for viewing by an operator, an access interface for receiving input from the operator, and a prosthesis design module providing design tools for creating a virtual 3D model of a dental prosthesis responsive to operator input.

Abstract: A radiation surveillance sensor system includes a radiation responsive sensor, a lightweight, radiation reflective member for selectively adjusting the incident radiation path to the sensor, and power means for controlling the position of the reflective member to achieve pan, tilt, or zoom functions for obtaining predetermined selectable view locations of the sensor. Similarly, a method for selectively controlling deflection of radiation from a field to be monitored by generating a 360 degree panoramic field of view includes the steps of fixedly positioning a radiation sensor for receiving radiation from a field to be observed, movably positioning a mirror-like surface for selectively reflecting radiation from the field to be observed towards the sensor, and rotatably driving the reflective mirror to selectively reflect radiation from the mirror to the fixedly mounted sensor to achieve up to a 360 degree panoramic view.

Abstract: A method for acquiring a surface profile 3D data set of an object includes illuminating a surface of the object with a sequence of multiple rainbow projection (MRP) structural light patterns, capturing light reflected from the object, and calculating 3D data (X, Y, Z) for each visible point on the object based upon triangulation mathematical principles of the captured reflected light.
