Abstract
SYSTEME DE DETECTION DE POSITION D'UNE AIGUILLE INDICATRICE. UN DISPOSITIF SELON L'INVENTION COMPREND UNE SOURCE LUMINEUSE FIXE QUI DIRIGE UN FAISCEAU DE LUMIERE ALLONGE SUR UN COTE DE L'AIGUILLE 12, AU MOINS UN DETECTEUR 54, 56, 58 PLACE DE L'AUTRE COTE DE L'AIGUILLE POUR DECELER UNE VARIATION DE LA QUANTITE DE LUMIERE QU'IL RECOIT, CETTE VARIATION CORRESPONDANT AU PASSAGE DE L'AIGUILLE ENTRE LUI ET LA SOURCE. LA POSITION DU DETECTEUR EST REGLABLE. DE PREFERENCE, ON UTILISE UNE SOURCE POURVUE D'UNE LENTILLE 112 A FACETTES 114, 116, 118. APPLICATION A UN APPAREIL RESPIRATOIRE MEDICAL, L'AIGUILLE ETANT CELLE D'UN MANOMETRE.
