摘要： Disclosed are a method and an apparatus for transmitting power wirelessly. The apparatus for wirelessly transmitting power includes: a power converter including an inverter for converting DC power into AC power, a resonance circuit, and two sensors for extracting a message transmitted from a receiving apparatus receiving power through magnetic induction of the resonance circuit; and a controller for controlling an operation of the inverter by selectively using messages extracted by the two sensors. When the controller fails in decoding the message extracted by one of the two sensors, the controller decodes the message extracted by the other of the two sensors and controls the operation of the inverter based on the decoded message. One of the two sensors is connected to a front stage of the inverter and the other of the two sensors is connected to a rear stage of the inverter.

摘要： Disclosed herein is a reception device for wireless charging. The reception device for wireless charging may include a reception antenna configured to generate an electric current based on a change of magnetism and a charging circuit unit configured to convert the electric current generated by the reception antenna into direct current. The reception antenna and the charging circuit unit may be connected to a flexible board. Accordingly, the reception device can be attached to the casing of a smart terminal while minimizing a change in the thickness of the smart terminal. A task for connecting the antenna and charging circuit unit of the reception device can be eliminated. A wireless charging function can be assigned to a smart terminal by simply replacing the casing of the smart terminal not having the wireless charging function.

摘要： The present invention relates to a recording speed determining method of a disk device. The present method, when data record is requested from a host through an interface, a disk device can receive size information about data to be recorded and/or the present time from the host, and determine a recording speed of a disk to be suitable for the received size information and/or for a time zone where the device is located. The disk device can determine such data size and time zone information internally. Thus, it is possible to reduce a noise that is caused from disk rotation if the size of data to be recorded is small or when a noise is felt relatively big. Further, it is possible to determine a data recording speed in accordance with a data size.

摘要： The method for transmitting power wirelessly according to an embodiment may comprise checking a position of a receiving device while wirelessly transmitting power to the receiving device, and changing a charging stop level which is compared with power loss which corresponds to a difference between transmitted power transmitted to the receiving device and received power received by the receiving device when the receiving device is outside a charging area. The receiving device is outside the charging area may be determined based on that the received power is equal to or greater than reference power and a power control level when transmitting the power to the receiving device is equal to or greater than a reference value. The charging stop level may be returned to an original value when the power loss is lower than the changed charging stop level until a predetermined time elapses after changing the charging stop level.
