Abstract:
Disclosed herein is a wireless power transmission system, including a transmitting unit generating and transmitting power for charging a battery; a receiving unit receiving transmitted power and charging the battery with power; and a transmission control unit controlling a magnetic induction method and a magnetic resonance method to be selectively used according to a distance between the transmitting unit and the receiving unit when the transmitting unit transmits power.
Abstract:
Disclosed herein are a multi wireless charging apparatus and a method for manufacturing the same. The multi wireless charging apparatus includes: a control unit wholly controlling a multi wireless charging process; and a plurality of wireless charging units electrically connected with the control and deformed into a roll form by being bonded so as to a plurality of interlayer voids at the time of laminating a plurality of flexible substrates. By this configuration, the multi wireless charging apparatus can be rolled up in a roll form while having a slim thickness and therefore, can be conveniently carried.
Abstract:
A wireless power transmission apparatus includes: a resonance circuit configured to be magnetically coupled to a wireless power receiving apparatus; a wireless communicator configured to form a near field communications channel with the wireless power receiving apparatus; and a cross controller configured to determine whether the wireless power receiving apparatus is cross-connected to the wireless power transmission apparatus based on first identification information received from the wireless power receiving apparatus through the resonance circuit and second identification information received from the wireless power receiving apparatus through the wireless communicator.

Abstract:
A thin-film ceramic capacitor includes a body in which dielectric layers and first and second electrode layers are alternately disposed on a substrate, and first and second electrode pads disposed on external surfaces of the body. A plurality of vias are disposed in the body. Each of a plurality of first vias connects the first electrode layers and the first electrode pad to each other. Each of a plurality of second vias connects the second electrode layers and the second electrode pad to each other. A separation slit is disposed to penetrate from an upper surface of the body and extend to the substrate, and the pluralities of first and second vias are disposed symmetrically with respect to the separation slit.
