Abstract

PROCEDIMIENTO DE DETERMINACION DE LAS COORDENADAS DE UNA ZONA DE CONTACTO DE UN OBJETO CONDUCTOR, COMO UN DEDO, SOBRE UNA SUPERFICIE SENSIBLE. COMPRENDE: A) POLARIZAR LOS DOS BORNES DE LA REJILLA, EN CONCORDANCIA DE FASE CON UNA SEÑAL DE RELOJ; B) REALIZAR UN MUESTREO SINCRONICO DE LA TENSION DE CADA BANDA DETECTORA, ALTERNATIVAMENTE PARA LOS PERIODOS DE INTERRUPCION Y DE ESTABLECIMIENTO; C) EFECTUAR LOS PROMEDIOS DE CIERTO NUMERO DE MUESTRAS, SEPARADAMENTE PARA LOS PERIODOS DE INTERRUPCION Y DE ESTABLECIMIENTOS; D) COMPARAR LOS DOS PROMEDIOS ASI OBTENIDOS, PARA DETECTAR SI SE PRODUCE CONTACTO; E) DETERMINAR LA COORDENADA NUMERICA POR EL NUMERO DE LA BANDA DONDE ES DETECTADO EL CONTACTO; F) POLARIZAR LOS DOS BORNES DE LA REJILLA EN OPOSICION DE FASE ENTRE ELLOS, PARA CREAR EN LOS MISMOS ALTERNATIVAMENTE UNA CORRIENTE EN UN SENTIDO Y EN EL SENTIDO OPUESTO EN CADA BANDA RESISTENTE; G) REALIZAR UN MUESTREO SINCRONICO DE LA TENSION DE LA CITADA BANDA DETECTORA; H) EFECTUAR EL PROMEDIO DE CIERTONUMERO DE MUESTRAS; I) EFECTUAR LA DIFERENCIA DE ESTOS PROMEDIOS, PARA CALCULAR LA COORDENADA ANALOGICA.
