Description
2003年5月15日に出願された米国特許仮出願シリアルNo.60/470,961号からの優先権を本出願は請求し、同仮出願の開示はここで援用される。
本発明は電界効果センサを2線のみを用いて制御システムまたは被制御装置に相互に接続する方法及び装置に関する。
タッチ・センサは、しばしば、機械的スイッチの置換用に望ましい。しかるに、機械的スイッチをタッチ・センサで置換する際には、或る限定が生じる。例えば、典型的機械的スイッチは簡単な2端子デバイスであるのに対して、従来のタッチ・センサは典型的には動作用に3線、即ち、電力入力線、接地線、出力線を必要とする。従って、タッチ・センサで機械的スイッチを置換することは、機械的スイッチでの使用に要求されない第3番目の線の追加をしばしば要する。これは、コスト及び複雑性を増加して、機械的スイッチ置換用としてのタッチ・センサの使用を或るアプリケーションでは禁止することになる。
