Abstract
L'invention porte sur des détecteurs de caractéristiques obscures. Un détecteur d'éléments obscurcis comprend un ensemble de plaques de capteurs comprenant trois plaques de capteurs ou plus, chacune des trois plaques de capteurs ou plus étant configurée pour former une première extrémité d'un champ électrique correspondant et pour prendre une lecture du champ électrique correspondant par le capteur. Le champ électrique correspondant varie en fonction de la proximité de la plaque du capteur par rapport à un ou plusieurs objets environnants et d'une propriété matérielle de chacun des objets environnants. Les trois plaques de capteurs ou plus comprennent une première plaque de capteur qui a une première forme et une seconde plaque de capteur qui a une seconde forme différente de la première forme de la première plaque de capteur. Le détecteur d'éléments obscurcis comprend également une ou plusieurs plaques communes pour former une seconde extrémité du champ électrique correspondant des trois plaques de détection ou plus.
