Pulsed antenna capacitive touch switch |
摘要 |
A capacitive touch switch suitable for use in areas with high environmental and electrical contamination employs a complex excitation signal that is demodulated to better distinguish it from environmental effects. Improved discrimination allows these sensed signals to be offset against a signal developed by a reference electrode to allow the system to operate robustly with contamination on the electrodes that would otherwise trigger or obscure pulses. |
