  • Patent number: 7113146
    Abstract: A broadband monopole is preferably formed as a single arm helical winding formed from copper, aluminum, or other suitable materials. The monopole is embedded in a lossy dielectric material that may include, for example, a potting material and a polyurethane resin or carbon-loaded ceramic shell. In alternate embodiments, the helical winding may be used without the dielectric material, although such an embodiment is not preferred because the input impedance is oscillatory and difficult to match. The resulting antenna operates over an extremely broad band and provides very uniform input impedance.

  • Patent number: 7106324
    Abstract: An image generating system and a program enabling scissoring of a polygon in a three-dimensional stage to prevent display failure of a polygon on a screen end or at a short distance from the viewpoint with a reduced computation load. The system performs scissoring processing for a polygon in a three-dimensional stage and generates an image of an object including a new vertex generated by the scissoring. A polygon which is at a short distance from a view point, displaying of which is likely to be missed, is scissored on side surfaces of a quadrangular pyramid forming a view volume, to prevent the display failure of the polygon existing at a short distance from the end of a screen. A polygon arranged in the three-dimensional space is subjected to coordinate transformation into a screen coordinate system, to detect an undrawable vertex, and a polygon containing the detected vertex is scissored at a portion containing the detected vertex, in a predetermined plane.
