Abstract: PURPOSE: A wireless power transfer device, a wireless power transfer controlling device, and a wireless power transfer method are provided to determine the coupling frequency between two resonators and control a transfer frequency to transfer power at the determined coupling frequency, thereby realizing high transfer efficiency without a separate matching circuit in spite of a distance change between the two resonators. CONSTITUTION: A wireless power transfer device comprises a determination unit and a controller. The determination unit determines the coupling frequency between a power resonator and a target resonator. The controller controls a transfer frequency to transfer power at the determined coupling frequency. The determination unit measures the reflective wave of a signal transmitted from the power resonator to the target resonator and determines the frequency with the minimum amplitude of the reflective wave as a coupling frequency(S510).

Abstract: 무선전력전송장치, 무선전력전송제어장치및 그방법이개시된다. 본발명의실시예들에따르면, 두공진기사이의결합주파수를결정하고상기결합주파수로전력이전송되도록전송주파수를제어함으로써, 두공진기사이의거리가변화하는경우에도별도의매칭회로(matching circuit) 없이높은전력전송효율을유지할수 있다.
Abstract translation: 提供无线电力传输装置（110），无线电力传输控制装置和无线电力传输方法。 确定源极谐振器（111）和目标谐振器（121）之间的耦合频率。 控制传输频率使得功率以耦合频率从源极谐振器（111）传输到目标谐振器（121）。 因此，即使当源谐振器（111）和目标谐振器（121）之间的距离改变时，也可以不使用附加匹配电路来保持高功率传输效率。

Abstract: An umbrella for a wheel chair comprises a fixing unit, a connection frame, and first and second cover units. The fixing unit is combined with the back of the wheel chair. The connection frame is fixed on the fixing unit to be able to be detached. The first cover unit is fixed on the connection unit and unfolded in a first direction. The second cover unit is fixed on a position different from the position on which the cover unit is fixed and unfolded in a second direction opposite to the first direction.
