  • Patent number: 8798812
    Abstract: Disclosed herein is a three-dimensional (3D) digital map system for implementing a navigation and ground collision preventing method using 3D terrain information. The 3D digital map system includes a terrain referenced navigation module configured to receive data from EGI (Embedded GPS/INS), a radio-altimeter (RALT) and a map database, corrects the data to perform accurate navigation computation, and outputs the corrected data, a collision avoidance warning module configured to generate a warning against collision of an aircraft with the ground or an obstacle using the corrected data, a 3D terrain database and an obstacle database, a terrain following module configured to generate a terrain following trajectory of the aircraft using the same information, and a Passive Ranging module configured to receive the 3D terrain database and line-of-sight (LOS) information of a target and calculate distance and position information of the target located on the ground.

  • Patent number: 8674579
    Abstract: The present invention relates to a stator core of a motor for a washing machine that is formed by connecting a plurality of arc-shaped core pieces to each other, each of the core pieces being formed by stacking core piece steel plates on top of each other and by bending the stacked core piece steel plates in such a manner that core piece teeth are disposed outward in the radial direction of a core piece yoke and the core piece yoke has the same curvature as a yoke of a stator core, the core piece yoke on each core piece steel plate having a plurality of incised portions for bending formed partially incised thereon between the respective neighboring core piece teeth on the opposite side to the side on which the core piece teeth are formed.
