Title
(EN) APERTURE ASSEMBLY FOR USE WITH A PHOTOSENSOR SYSTEM AND A SECURING MECHANISM FOR THE APERTURE ASSEMBLY
(FR) ENSEMBLE OUVERTURE POUR UNE UTILISATION AVEC UN SYSTÈME DE CELLULES PHOTOSENSIBLES ET MÉCANISME DE FIXATION POUR L'ENSEMBLE OUVERTURE
Abstract
(EN)
A cost-effective photosensor system for rotor position detection includes securing an aperture assembly to an off-the-shelf infrared radiation-emitting component and/or an off-the shelf infrared radiation-detecting component. The application discloses an aperture assembly that may be stamped from a thin, opaque, elongated piece of plastic having an aperture window through which a radiation beam may pass and be focused. The aperture assembly also has a locking system for securing the assembly to the off-the-shelf photosensor system component, and an alignment system to direct the infrared radiation beam. A replaceable stamped aperture assembly for use in a rotor-sensing system and a method of providing a replaceable aperture assembly and securing it to an infrared component of a photosensor system are also disclosed.

La présente invention concerne un système de cellules photosensibles rentable pour la détection de la position d'un rotor qui comprend la fixation d'un ensemble ouverture à un composant émettant un rayonnement infrarouge en vente libre et/ou un composant de détection de rayonnement infrarouge en vente libre. La demande concerne un ensemble ouverture qui peut être matricé à partir d'un morceau allongé, opaque et mince de plastique comportant une fenêtre à travers laquelle un faisceau de rayonnement peut passer et être focalisé. L'ensemble ouverture comporte également un système de verrouillage pour fixer l'ensemble composant du système de cellules photosensibles en vente libre et un système d'alignement pour diriger le faisceau de rayonnement infrarouge. L'invention concerne également un ensemble ouverture matricé remplaçable pour une utilisation dans un système de détection de rotor et un procédé consistant à fournir un ensemble ouverture remplaçable et le fixer à un composant infrarouge d'un système de cellules photosensibles.
