Abstract

Se proporcionan sistemas sensores de oclusión y métodos de uso de los sistemas sensores de oclusión. En una modalidad general, la presente descripción proporciona un dispositivo sensor que incluye un tubo y un sensor reflectivo infrarrojo que comprende un emisor de luz infrarroja y un receptor fototransistor infrarrojo o fotodiodo. El sensor reflectivo infrarrojo y el receptor fototransistor infrarrojo o fotodiodo están colocados en o cerca del tubo de modo que una luz infrarroja pueda ser transmitida a una porción del tubo y al menos una porción de la luz infrarroja reflejada desde la porción del tubo puedan ser detectadas por el receptor fototransistor infrarrojo o fotodiodo.
