本発明の実施形態は、電子装置に結線された二次コイルと誘導結合する、電源に結線された少なくとも1つの一次コイルを備える誘導性電力アウトレットによる送電の効率を監視する方法を提供することを対象とする。この方法は、一次コイルに送出された入力電力を測定するステップと、電気装置が受け取った出力電力を測定するステップと、入力電力をプロセッサに通信するステップと、出力電力をプロセッサに通信するステップと、プロセッサが電力損失インデックスを決定するステップとを含む。

を含む。
本発明の別の態様は、電気装置に結線された二次コイルと誘導結合する、電源に結線された少なくとも1つの一次コイルを備える種類の誘導性電力アウトレットを見つける電力アウトレットロケータを提供することを対象とする。通常、電力アウトレットロケータは、少なくとも1つの電力アウトレットを検出する少なくとも1つのセンサと、少なくとも1つのセンサからセンサ信号を受信し、少なくとも1つの電力アウトレットのロケーションの少なくとも1つの座標を計算する少なくとも1つのプロセッサと、信号をプロセッサから受信し、ロケーションをユーザに伝える少なくとも1つのユーザインタフェースとを備える。
