Abstract

Aparato para percibir un punto deseado en una curva representativa de la variación de dos entradas relacionadas, generadas por una porción generalmente lineal y dicho punto deseado se encuentra más allá de dicha porción generalmente lineal, comprendiendo dicho aparato: primeros medios para generar una señal representativa del gradiente instantáneo de dicha curva, y segundos medios que responden a dicha señal de gradiente para determinar un cambio significativo en la pendiente de dicha curva que contiene dicho punto deseado, incluyendo dichos segundos medios unos medios para almacenar una señal representativa del gradiente de dicha curva en la porción generalmente lineal de la misma y para generar una señal de control cuando dicha señal de gradiente instantánea tiene una relación predeterminada con respecto a dicha señal almacenada en dicho punto deseado.
