  • Selective inhibition of bonding of power particles for layered fabrication of 3-D objects
    Patent number: 6589471
    Abstract: A method for fabricating a three-dimensional (3-D) object is disclosed. The method includes providing a layer of powder material, and selectively depositing bonding inhibitor on selected areas of the layer of powder material. The areas to be deposited with the bonding inhibitor are selected according to a cross-section design of the 3-D object. The method also includes promoting bonding of uninhibited areas of the entire layer of powder material by either sintering or balk deposition of chemical binders. The method further includes repeating the steps of providing a layer of powder material, selectively depositing bonding inhibitor, and promoting bonding until the 3-D object is formed.

  • Hand-held electronic stereoscopic imaging system with improved three-dimensional imaging capabilities
    Publication number: 20030020807
    Abstract: An improved stereoscopic imaging system that includes a pair of image capturing components and a pair of eyepieces, wherein the distance between the image capturing components may be varied substantially independently of the distance between the eyepieces. In a preferred embodiment, the stereoscopic imaging system comprises a housing having two telescope chambers, each telescope chamber containing an objective lens and an image capturing component. The telescope chambers are preferably attached to an adjustment assembly that allows a user to adjust the distance between the chambers and thus the distance between the imaging capturing components contained therein to enhance and vary the 3-D effect of the images captured by the image capturing components. The stereoscopic imaging device also preferably includes internal circuitry that can communicate with a remote system by wire hook-up or by wireless communication.

  • Incremental digitizer for encoding geometrical forms
    Patent number: 4500749
    Abstract: A digitizer for digitizing two and three dimensional geometrical forms. The digitizer uses extensible cords on pivotal reels. Information on cord extension and pivot angle is utilized to calculate stylus position in a desired coordinate system. Three dimensional objects rest upon a pivotal table which also provides digitizing information.
