Abstract

"SENSOR CAPACITIVO". Um sensor capacitivo para montagem em um corpo, particularmente um corpo tal como uma porta de van. O sensor possui uma placa de sensor à qual um primeiro sinal é aplicado. Uma primeira placa de proteção é intercalada entre a placa de sensor e o corpo, e uma segunda placa de proteção é intercalada entre a primeira placa de proteção e o corpo. As primeira e segunda placas de proteção possuem cada uma sinais aplicados as mesmas que são iguais ou pelo menos similares ao primeiro sinal aplicado à placa de sensor. Dessa forma, a segunda placa de proteção age como uma proteção posterior para a primeira proteção e reduz sua capacitância ao aterramento. Isso reduz a corrente sugada pela primeira proteção, permitindo que a mesma rastreie de forma mais precisa o sinal no sensor e conseqüentemente mascare melhor a placa de sensor do corpo.
