  • Patent number: 10373750
    Abstract: The present invention relates to an apparatus of generating momentum which drives an object. The present invention provides a momentum generating apparatus in which a pair of high temperature superconducting coils which are wound in different directions and have different superconducting properties are arranged in parallel and the same current flows in the pair of coils to be in a stable state where magnetic fields generated in the coils are cancelled and an asymmetric current is suddenly applied to the pair of coils through a switching operation to generate a magnetic field and an eddy current is induced in a plate due to the generated magnetic field and the plate is floated using a repulsive force between the magnetic field generated in the plate due to the eddy current and the magnetic field generated in the pair of coils, to instantaneously generate force using a small amount of superconducting coils.

  • Patent number: 8081953
    Abstract: A method for providing pictures to a digital frame based on home networks is disclosed. A frame service server receives an image information message from user equipment which connects with a specific number. The frame service server grasps an IP of an RG installed in a home of a service destination by searching identification information included in the image information message at an RG identification table. The frame service server transmits the image information message including port number information to the IP of the RG, which is selected for informing the frame service. The RG transmits the image information to a digital frame so that the digital frame displays the image information.
