Abstract
UN APARATO PARA LA ENTRADA DE COORDENADAS EN EL QUE SE DETECTA LA ENTRADA DE VIBRACION POR UNA PLUMA DE VIBRACION MEDIANTE SENSORES DE VIBRACION UNIDOS A PREDETERMINADAS POSICIONES DE UN PLATO DE PROPAGACION HECHO DE UN PLATO DE VIDRIO TRANSPARENTE O SIMILAR, DETECTANDOSE LA POSICION DE LA COORDENADA DE LA PLUMA SOBRE EL PLATO EN BASE A LOS TIEMPOS DE PROPAGACION DE LA VIBRACION QUE SE REQUIEREN HASTA QUE LA VIBRACION SEA DETECTADA POR LOS SENSORES. LAS PORCIONES PROXIMAS A LOS BORDES LATERALES FUERA DEL AREA DE ENTRADA DE LA COORDENADA DEL PLATO SE CURVAN MUCHO Y LENTAMENTE, IMPIDIENDO ASI LA GENERACION DE ONDAS REFLEJADAS DESDE LA PERIFERIA DEL PLATO. LA RELACION DEL AREA DE ENTRADA DE LA COORDENADA EFECTIVA AL TAMAÑO DEL CUERPO PRINCIPAL DE TODO EL APARATO SE ESTABLECE EN UN VALOR ALTO DE MANERA QUE EL APARATO PUEDA COVERTIRSE EN UNA MINITATURA.
