Abstract
SE PRESENTA UN METODO PARA DETECTAR, EN UN APARATO Y UN PROCESO CONTROLADOS, LA PARALIZACION O EL FALLO DE UN PROCESO DE DETECCION Y UN DISPOSITIVO QUE COMPRENDE UN DETECTOR QUE GENERA UNA SEÑAL DE SALIDA DE DETECTOR Y LOS COMPONENTES RELACIONADOS QUE CONVIERTEN LA SEÑAL DE SALIDA DEL DETECTOR EN UNA SEÑAL DE PROCESAMIENTO DERIVADA DE LA SEÑAL DE SALIDA DEL DETECTOR, ESTANDO SUJETO EL DETECTOR A VARIACIONES TRANSITORIAS CONTINUAS DEBIDAS AL RUIDO DEL PROCESO EN EL APARATO Y EL PROCESO CONTROLADOS, EL METODO COMPRENDE LOS PASOS DE: DETERMINAR EN MODO DE PROCESAMIENTO DE TIEMPO REAL UNA ESTIMACION DE LA DESVIACION ESTANDAR DE LA SEÑAL DEL PROCESO, COMPARAR LA ESTIMACION DE LA DESVIACION ESTANDAR DE LA SEÑAL DEL PROCESO CON AL MENOS UN VALOR DE REFERENCIA PREDETERMINADO, Y PRODUCIR UNA SEÑAL DE NO ACEPTACION SI LA COMPARACION DA COMO RESULTADO LA DETERMINACION DE UNA DESVIACION INACEPTABLE ENTRE LOS VALORES COMPARADOS. ADEMAS, SE DESCRIBE UN APARATO PARA DETECTAR, EN UN APARATO Y UN PROCESO CONTROLADOS, LA PARALIZACION O EL FALLO DE UN PROCESO Y UN DISPOSITIVO DE DETECCION.
