Abstract
Se provee un sistema de detección de pasajero; un sensor mide la capacitancia, efectos de campo eléctrico u otra característica que responde a una carga en un área de asiento; el sensor usa uno o más electrodos (v.gr., un electrodo de transmisión o recepción o un electrodo para transmitir y uno o más electrodos para recibir); otros electrodos están conectados con diferentes impedancias; la medición por un sensor, pero con otros electrodos conectados con diferentes impedancias, puede distinguir entre un ocupante y objetos inanimados, puede distinguir entre características de un pasajero (v.gr., tamaño, estatura, peso o posición), o puede indicar un estado de conexión a tierra de un ocupante.
