20150028802 | WIRELESS CHARGING DEVICE AND METHOD FOR CONTROLLING THE SAME - A wireless charging device may include: a sensor unit sensing an input from an external device and generating a wake-up signal; a control unit, upon receiving the wake-up signal, exiting from a sleep mode to enter an active mode, and generating an activation signal; a detection unit receiving the activation signal from the control unit to detect a mobile terminal; and a power supply unit, in the case that the detection unit detects the mobile terminal, supplying power to the mobile terminal wirelessly. | 01-29-2015 |
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 |
20150133056 | NON-CONTACT TYPE POWER SUPPLY APPARATUS AND NON-CONTACT TYPE POWER SUPPLY METHOD - A non-contact type power supply apparatus may include a power unit transmitting power to a power receiving apparatus in a non-contact type manner, a communicating unit communicating with the power receiving apparatus, and a controlling unit terminating communications with the power receiving apparatus in the case in which a communications signal level of the power receiving apparatus transmitted to the communicating unit is equal to or less than a reference signal level. | 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 |
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 |
20160036245 | WIRELESS POWER TRANSMITTER - A wireless power transmitter includes a case including a base plate and a structure disposed on the base plate; and a transmitting coil having a three-dimensional spiral shape disposed on a side surface of the structure and configured to generate a magnetic field in a direction perpendicular to the side surface of the structure. | 02-04-2016 |
