Peter L. Diaconescu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • DIGITIZER USING PLURAL CAPTURE METHODS TO IMAGE FEATURES OF 3-D OBJECTS
    Publication number: 20100141960
    Abstract: A method and apparatus to digitize three-dimensional objects. A projection assembly is retained in fixed relation to an imaging assembly. The projection assembly projects a fixed gradient light pattern into a focal zone of the imaging assembly. The imaging assembly integrates the illumination over time such that the fixed gradient reveals the features of the three dimensional object.
    Type: Application

  • Three dimensional digitizer using multiple methods
    Patent number: 6980302
    Abstract: A method and apparatus capable of using two or more capture methods to create three-dimensional representations of a target captured. Elements of the three-dimensional digital representation generated from the plural capture method are combined to yield a single digital three-dimensional representation having improved quality.

  • Digitizer using intensity gradient to image features of three-dimensional objects
    Publication number: 20040061871
    Abstract: A method and apparatus to digitize three-dimensional objects. A projection assembly is retained in fixed relation to an imaging assembly. The projection assembly projects a fixed gradient light pattern into a focal zone of the imaging assembly. The imaging assembly integrates the illumination over time such that the fixed gradient reveals the features of the three dimensional object.
