Power transmitting apparatus, power receiving apparatus, control methods thereof, and program
First Claim
1. A power transmitting apparatus that transmits power to a power receiving apparatus, the power transmitting apparatus comprising:
- a first power transmission unit configured to execute wireless power transmission intermittently using a first antenna;
a detection unit configured to detect a signal received from the power receiving apparatus in response to the power transmission by the first power transmission unit;
a second power transmission unit configured to execute, in the case where the signal has been detected by the detection unit, wireless power transmission having longer period than a period of the power transmission by the first power transmission unit using the first antenna;
a third power transmission unit configured to execute wireless power transmission having larger amount of power than amounts of power of the power transmission by the first power transmission unit and power of the power transmission by the second power transmission unit using the first antenna; and
a communication unit configured to execute, after the second power transmission unit executes the power transmission, communications with the power receiving apparatus to determine whether to cause the third power transmission unit to execute the power transmission using a second antenna different from the first antenna.

Abstract
A power transmitting apparatus that transmits power to a power receiving apparatus executes intermittent wireless transmission of power. The power transmitting apparatus operates according to one of a first power transmitting method including detecting a signal load-modulated by the power receiving apparatus using an ID in response to the transmitted power during the intermittent transmission and a second power transmitting method including transmitting the power having modulated the power according to an ID determined in advance so that the power receiving apparatus detects the ID determined in advance.
