Abstract
Description
誘導電力移送(IPT)フィールドを生成するよう構成された少なくともひとつの電力送信コイルと、
生成された場合の前記IPTフィールドによって占められるスペース内のまたはそのスペースに隣接した物体を検出するよう構成された物体検出システム。
前記物体検出システムは、受信体に関連付けられたタグに基づいて該受信体を検出するよう構成される。
・永久磁石を含む受信器タグ、および該永久磁石に応答するよう構成され、かつ他の磁石には必ずしも応答しないよう構成された磁気センサを含むODシステム。
・電磁石などの非永久磁石を含む受信器タグ、および、受信器タグが送信器に近づいたときに該非永久磁石を活性化させるODシステムまたは送信器制御。この活性化は例えば送信器から受信器へ伝達されるある種の信号(例えば、変調IPT信号)を通じてなされ、または送信器のIPTコイルやODシステムの他の磁石からの磁束の受領を通じてなされる。これは、DC電圧でエネルギ付与される受信器コイルを用いて実装されてもよい。受信器がこれを用いていったん特定されると、受信器コイルからエネルギが取り去られ、その結果それは電力を受けることを開始できるようになり、ODシステム202は取り外しが決定されるまで受信器特定モードにある。受信器の取り外しは、電力移送、期間または他の通信チャネルを測定することにより決定されてもよい。
・受信器タグは符号化された反射性表面を含み、ODシステムは反射光パターンを測定するよう構成された光検出器を含む。
