  • Measuring method of critical current density of superconductor wires using measurement of magnetization loss
    Patent number: 8788227
    Abstract: A method for measuring critical current density of superconductor wires according to the present invention is characterized in that it includes: (a) applying an external magnetic field to the superconductor wires, (b) measuring a magnetization loss of the superconductor wires according to the application of the external magnetic field, (c) normalizing the measured magnetization loss, and then calculating a fully-penetration magnetic field of the superconductor wires according to the normalized magnetization loss, (d) calculating a critical current density of the superconductor wires according to the calculated fully-penetration magnetic field. Therefore, the critical current density of parallel superconductor wires such as stacked superconductor wires may be measured without applying current to the superconductor wires directly.

  • Contact module for rechargeable battery, mobile electronic device having the same contact module and method of preventing rechargeable battery from exploding using the same contact module
    Patent number: 8405363
    Abstract: A mobile electronic device having a contact module and a method of preventing a rechargeable battery from exploding using a contact module. The contact module includes a contact module body disposed inside a mobile electronic device; a plurality of contact terminals elastically fitted to the contact module body to be electrically connected to contact terminals of the rechargeable battery; and a temperature sensor module disposed on one side of the contact module to detect a temperature of the rechargeable battery. The contact module is embodied by setting contact terminals and a temperature sensor module into one unitary module, and can correctly measure the temperature of the rechargeable battery to effectively prevent the rechargeable battery from exploding when the battery is being charged.
