A wireless power transmitting method performed in a wireless power transmitting apparatus includes transmitting a long beacon signal via a transmitting coil; determining whether or not a response signal to the long beacon signal has been received at a wireless communicator; determining whether or not a degree of change in a level of impedance of the transmitting coil is within a reference range responsive to the determination that the response signal is not received; and wirelessly transmitting the power responsive to the determination: that the response signal has been received or that the degree of change is within the reference range.

Wireless power transmitting apparatus and method

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.

Apparatus and method for transmitting and receiving power wirelessly

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.

Wireless power transmitter

A non-contact type power supplying apparatus may be capable of detecting another power receiving apparatus even during the charging. The non-contact type power supplying apparatus may include: a first output unit outputting a detection signal detecting a power receiving apparatus; and a second output unit outputting a wake-up signal waking-up a communications circuit of the detected power receiving apparatus when the power receiving apparatus is detected, thereby making it possible to supply power to the detected power receiving apparatus using a non-contact type method.

Non-contact type power supplying apparatus and non-contact type power supplying method

A non-contact power transmission device includes a power transmission unit configured to contactlessly provide electric power; a controller configured to provide location information of the non-contact power transmission device; and a communications unit configured to transmit the location information and product information received from a non-contact power reception device to a server, and receive an approval to transmit electric power to the non-contact power reception device from the server.

Non-contact power transmission device and location-based service system using the same

A non-contact type power transceiving apparatus may include: a non-contact type power transmitting apparatus adjusting bias power setting a level of transmission power based on a request and transmitting one of a first power and a second power having a power level higher than that of the first power in a non-contact scheme; and a non-contact type power receiving apparatus requesting one of the first power and the second power from the non-contact type power transmitting apparatus and varying a set temperature level determining an abnormal state based on the requested power.

Non-contact type power transmitting apparatus, non-contact type power receiving apparatus, and non-contact type power transceiving apparatus

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.
