特定のシステム構成要素を示すために、ある種の用語が以下の説明および特許請求の範囲全体を通じて使用される。当業者は理解するであろうように、電気外科システムを設計し、製造する企業が、ある構成要素を異なる名称によって呼ぶ場合がある。本願は、機能ではなく、名称が異なる構成要素間を区別するものとは意図していない。
E(tn)=I(tn)xV(tn)xΔt (1)
式中、E(tn)は、時間長さΔtの区間tnにおいて配給されるエネルギーであり、I(tn)は、その区間についての実電流測定結果であり、V(tn)は、その区間についての測定済みまたは仮定電圧である。次いで、各区間について計算されるエネルギー配給は、それぞれの時間ウィンドウにおけるエネルギー値を決定するために加算システムによって使用される。
