Abstract

Un método para determinar una altura de una abertura de una vidriera corrediza formada por una vidriera corrediza movible en una campana de ventilación. El método incluye proporcionar un dispositivo láser en la campana y proporcionar un reflector en la vidriera corrediza. Además, el método incluye posicionar la vidriera corrediza en una posición abierta para formar la abertura de vidriera corrediza y medir una primera distancia entre el dispositivo láser y el reflector cuando la vidriera corrediza está en la posición abierta. El método también incluye calcular la altura de la vidriera corrediza con base en la primera distancia.
