  • Patent number: 10284002
    Abstract: A reception device for receiving wireless power may include: a power reception circuit configured to wirelessly receive power from a transmission device, rectify the received power, and output the rectified power; a charger configured to process the rectified power received from the power reception circuit and charge a battery of the reception device or output the rectified power to a system of the reception device; and a control circuit configured to, when an event for changing an input current limit of the charger is detected, gradually change the input current limit of the charger by stepping up or stepping down the input current limit to one or more intermediary values until the input current limit reaches a predetermined value.

  • Publication number: 20160175606
    Abstract: Disclosed herein is an optical stimulator inserted into a biological tissue for obtaining a neural signal by stimulating a neuron with a propagating light. The optical stimulator includes: a main unit comprising electrodes, and electrical terminals connected to the electrodes; a waveguide extended from a side of the main unit and comprising electrochromic films; and a light source disposed in the main unit and producing light along a direction in which the electrochromic films formed in the waveguide are arranged. Each of the electrical terminals is connected to the respective electrochromic films, and the electrochromic films change a propagation path of light reaching the electrochromic films upon a voltage being applied thereto from the electrical terminals, to stimulate a neuron.
