Abstract

Ce dispositif de sortie d'informations comprend : une unité d'acquisition de position qui acquiert des données de position à des intervalles de temps prescrits ; et une unité de commande qui amène une unité de sortie à fournir des informations prédéterminées si la position indiquée par les données de position acquises par l'unité d'acquisition de position change séquentiellement et passe à une position de détection prescrite.
