Abstract

Un método de detección de un suceso (110) en una estructura mecánica, por medio de sensores (50) y al menos un actuador (60), comprendiendo el método: generar en la estructura una señal excitada, usando el al menos un actuador (60); detectar una señal reflejada desde el suceso, utilizando cada uno de tres o más de los sensores (50), estando situados los tres o más de los sensores (50) alrededor de un círculo que tiene un eje central (100), y estando situados los sensores y el al menos un actuador (60) concéntricamente con respecto al eje central (100); determinar respectivas duraciones de tiempo, durante las cuales la señal reflejada se desplaza desde el suceso (110) hasta cada uno de los sensores (50); y calcular una ubicación del suceso (110) mediante el uso de las diferencias en las respectivas duraciones de tiempo, durante las cuales la señal se desplaza desde el suceso (110) hasta cada uno de los sensores (50), para determinar un ángulo y una distancia a los que está posicionado el suceso (110).
