WIRELESS POWER TRANSMISSION APPARATUS AND METHOD
First Claim
1. A wireless power transmission apparatus for preventing a misconnection between the wireless power transmission apparatus and a wireless power reception apparatus in an environment in which a plurality of wireless power transmission apparatuses charge a plurality of wireless power reception apparatuses, the wireless power transmission apparatus comprising:
- a detector configured to detect a signal induced in a resonator; and
a controller configured to determine either one or both of a transmission interval of a wake-up power and a point in time at which the wake-up power is transmitted to prevent a waveform of the detected signal from overlapping a waveform of the wake-up power.

Abstract
A wireless power transmission apparatus for preventing a misconnection between the wireless power transmission apparatus and a wireless power reception apparatus in an environment in which a plurality of wireless power transmission apparatuses charge a plurality of wireless reception apparatuses includes a detector configured to detect a signal induced in a resonator, and a controller configured to determine either one or both of a transmission interval of a wake-up power and a point in time at which the wake-up power is transmitted to prevent a waveform of the detected signal from overlapping a waveform of the wake-up power.

9. A wireless power transmission apparatus for preventing a misconnection between the wireless power transmission apparatus and a wireless power reception apparatus in an environment in which a plurality of wireless power transmission apparatuses charge a plurality of wireless power reception apparatuses, the wireless power transmission apparatus comprising:
-
a detector configured to detect a signal induced in a resonator; a controller configured to determine a point in time at which a wake-up power is transmitted to be different from a point in time at which a waveform of the detected signal changes; and a recognizer configured to control a point in time at which low power to be used for communication by the wireless power reception apparatus is supplied to the resonator, and recognize a normal connection of a wireless power reception apparatus located in a charging area of the wireless power transmission apparatus, in response to a search message being received from the wireless power reception apparatus performing communication using the wake-up power. - View Dependent Claims (10, 11, 12, 13)

14. A wireless power transmission method of preventing a misconnection between a wireless power transmission apparatus and a wireless power reception apparatus in an environment in which a plurality of wireless power transmission apparatuses charge a plurality of wireless power reception apparatuses, the method comprising:
-
detecting a signal induced in a resonator; and determining either one or both of a transmission interval of a wake-up power and a point in time at which the wake-up power is transmitted to prevent a waveform of the detected signal from overlapping a waveform of the wake-up power. - View Dependent Claims (15, 16, 17, 18, 19)

20. A wireless power transmission method of preventing a misconnection between a wireless power transmission apparatus and a wireless power reception apparatus in an environment in which a plurality of wireless power transmission apparatuses charge a plurality of wireless power reception apparatuses, the method comprising:
-
detecting a signal received from another wireless power transmission apparatus; and transmitting a wake-power to be used for communication by the wireless power reception apparatus based on the detected signal so that the wake-up power is not transmitted while a signal is being received from the other wireless transmission apparatus. - View Dependent Claims (21, 22)
