  • Patent number: 10574300
    Abstract: A wireless power transmitter for transmitting power by wireless to a terminal includes a power conversion unit and a power transmission control unit. The power conversion unit forms a wireless power signal for wireless power transfer using power supplied from a power supply unit. The power transmission control unit regulates a characteristic of the supplied power, based on orientation information of the terminal. A terminal includes a power receiving unit and a control unit. The power receiving unit receives a wireless power signal formed by a wireless power transmitter. The control unit detects whether or not an orientation of the terminal is changed while the wireless power signal is received, and transmits a control message for power regulation to the wireless power transmitter when the change in the orientation of the terminal is detected.

  • Publication number: 20150159027
    Abstract: A connector and a cable can absorb low frequency electromagnetic waves when formed of a material including a conductive nanomaterial and a magnetic metal material. Because the conductive nanomaterial and a magnetic metal nanowire or nanoparticle have high permeability as compared to the conductive nanomaterial alone, low frequency electromagnetic waves can be absorbed, and electrical interference among various electric/electronic parts can be minimized.
