| Number | Title | Issue Date |
| 8172575 | Map in azimuthal equidistant hemispheric projection with reduced distortion According to one embodiment, world maps in the Azimuthal Equidistant (AE) Hemispheric projection are formed by depicting the main hemisphere of a globe in full and the opposing hemisphere in the form of two semi-hemispheres contiguous two spaced side portions of the... | 05/08/2012 |
| 7331790 | Map (profile) of the earth's continents and methods of manufacturing world maps World maps for the earth's continents are formed from the continental hemisphere as a main body by attaching several sections of the oceanic hemispheres. Folding the hemispheres in half repeatedly makes near-flat disk maps of the both hemispheres. Other methods of p... | 02/19/2008 |
| 6612843 | Globe base educational device The present invention comprises an educational device for use with an earth globe having ecliptic angle of inclination for teaching students the position of the earth relative to the sun through the various seasons. The educational device can also be used... | 09/02/2003 |
| 6464502 | Three-dimensional intra-globe model A globe that shows internal structures of the earth three-dimensionally. The globe comprises a plurality of concentrically arranged spheres 1, 2, 3, 4 which are made of a transparent material except the innermost sphere and three-dimensional displaying me... | 10/15/2002 |
| 6398221 | Polyhedron globe puzzle system The polyhedron globe puzzle system of this invention comprises a plurality of scalene triangles with attachment means so as to form a generally spherical body on which is inscribed a world map such that the position of the scalene triangles contains laten... | 06/04/2002 |
| 6221457 | Display system for curved surfaces A flexible sheet can be stored or patterned while in a flat configuration, and subsequently readily adapted to overlay a curved surface, for example a hemisphere of a sphere. Radial incisions made to the sheet provide a hub and a plurality of substantiall... | 04/24/2001 |
| 6068486 | Multidisplay globe with overlays A multidisplay globe comprising a globular body including a globe spherical surface representing the earth, support means for mounting the globular body, and spherical film overlays removably mounted over the globe spherical surface for displaying selecte... | 05/30/2000 |
| 5695342 | World map system A world map system consists of thirty-two loose maps in the form of twelve equilateral pentagons and twenty inequilateral hexagons having alternately a relatively short side and a relatively long side. With these maps a globe can be formed by surrounding ... | 12/09/1997 |
| 5676550 | Plate tectonic earth planet model An Earth planet model based on the science of plate tectonics. Accordingly, the model (10) includes a plurality of curved members (12), each curved member representing one of Earth's crustal tectonic plates. Each plate member (12) is formed of a durable, ... | 10/14/1997 |
| 5222896 | Polyhedral approximation of a spherical body and two-dimensional projections therefrom A polyhedral approximation of an Earth globe or other non-planar surface and a projection of such non-planar surface to a two-dimensional form with a practical minimum of distortion of principal and secondary features is disclosed. Vertices are selected o... | 06/29/1993 |
| 4773861 | Map with a homogeneous grid system A geographic map-grid network constructed on a sphere is obtained by inverse gnomonic transfer of a Rome de l'Isle polyhedron (P) circumscribed about a sphere (S) in accordance with local transfers centered at the point of tangency (E) of each lozenge-sha... | 09/27/1988 |
| 4627622 | Map puzzle having periodic tesselated structure A puzzle comprising a planar map projection is formed from a conformal projection of the earth's surface onto an equilateral tetrahedron whose apices are located at preselected significant points on the surface, for example, major airports, major seaports... | 12/09/1986 |
