Abstract
Description
(1)電力受信器330は通信経路110aを利用して近傍にあるどの電力送信器330aにも自らの存在を示すことができる。
(2)電力送信器330aは通信経路110aを通じて自らの存在を示し、そのアンテナ208または結束部204のうちの一つのみで送信を始めることがある。
(3)電力受信機330bは通信経路110aからかすかな信号を受け取ったことを認識することがある。
(4)電力送信器330aは他のアンテナ208または結束部204を、位相を初期値のゼロにして動作を開始させ、通信経路110aを通じて電力受信機330bに信号の強度を送るように要求することができる。
(5)電力受信機330bは、受け取った信号が以前よりも強い、同様、または弱いことを示す信号を返信することができる。
(6)信号が以前よりも弱いまたは同様である場合、コントローラー310は結束部240における位相を(1/2)π増加させ、他の信号強度を送信するよう要求できる。
(7)ステップ5および6は全ての位相について繰り返される。
(8)信号強度の増加がみられない場合、この特定の結束部240の動作を終了させ、他の結束部が一連の作業において使用され、ステップ4から繰り返される。
(9)ステップ4から6は全てのエミッターの結束部が使用されている状態になるまで繰り返される。
