20150115726 | ELECTRONIC DEVICE - There is provided an electronic device including: a power reception unit having a plurality of power receiving coils and receiving a wireless power signal from a wireless power transmission device; a switching unit controlling an ON/OFF switching operation of the plurality of power receiving coils; and a control unit obtaining reception sensitivity of the power reception unit and controlling the switching unit based on the obtained reception sensitivity. | 04-30-2015 |
20150130291 | NON-CONTACT TYPE POWER TRANSMITTING COIL AND NON-CONTACT TYPE POWER SUPPLYING APPARATUS - A non-contact type power transmitting coil may include at least one conductor pattern disposed on at least one surface of a base having a predetermined area, having a plurality of turns, and transmitting received power externally in a non-contact manner. The intervals between at least some of adjacent pattern portions of the conductor pattern in a direction from a center portion of an inner diameter of the conductor pattern to an outermost pattern portion conductor pattern may be different from one another. | 05-14-2015 |
20150130410 | BATTERY PACKAGE AND ELECTRONIC DEVICE HAVING THE SAME - There is provided an electronic device including a power-receiving unit configured to receive power by a contactless scheme, a battery package including a battery cell configured to be charged with the power received by the power-receiving unit, and an electronic device main body configured to receive the power from the battery package to perform a set operation. | 05-14-2015 |
20150179335 | COIL DEVICE, AND WIRELESS POWER TRANSMITTER AND WIRELESS POWER RECEIVER HAVING THE SAME - A coil device may be capable of varying the gap of a coil so that several devices may be wirelessly charged simultaneously or a single device may be wirelessly charged with concentrated power. The coil device may include: a case having a reception space and varying a charging area upon a user's selection; and a coil part, having, in the reception space of the case, a coil body formed of a wound conductor having a predetermined length. A gap of the wound conductor of the coil body varies as the charging area of the case varies. | 06-25-2015 |
20150200048 | COMPOSITE FERRITE SHEET, METHOD OF MANUFACTURING THE SAME, AND ELECTRONIC DEVICE INCLUDING THE SAME - A composite ferrite sheet may include a ferrite sheet, and composite sheets attached to both surfaces of the ferrite sheet, respectively, and having insulating properties. The composite sheet may be formed of a resin containing metal powder particles. The composite ferrite sheet may be easily manufactured and have improved shielding performance. | 07-16-2015 |
20150244424 | TRANSMITTING AND RECEIVING POWER WIRELESSLY - An apparatus for transmitting power wirelessly includes a power transmitter configured to transmit power wirelessly to an apparatus for receiving power wirelessly, and an identification information manager configured to transmit first identification information allocated to the apparatus for transmitting power wirelessly to other devices. | 08-27-2015 |
20150333532 | WIRELESS POWER TRANSMITTER - A wireless power transmitter according to an exemplary embodiment in the present disclosure may include a transmitting core; a transmitting coil provided on the transmitting core and transmitting power wirelessly; and a magnetic body provided on the transmitting core and allowing a virtual line which is normal to a surface of the magnetic body to form an acute angle with the transmitting core. | 11-19-2015 |
20150333562 | WIRELESS CHARGING TRANSMITTER AND WIRELESS CHARGING SYSTEM USING THE SAME - A wireless power transmitter is electromagnetically coupleable to a receiving coil of a wireless power receiver to provide power wirelessly and includes a substantially planar transmitting core. A transmitting coil has a plurality of windings and is disposed on a surface of the transmitting core. The transmitting core may extend beyond the transmitting coil in a planar direction. | 11-19-2015 |
