Abstract: L'invention porte sur une loupe binoculaire qui contient une ou plusieurs lentilles remplies de fluide, hermétiquement scellées. La loupe binoculaire comprend un ou plusieurs oculaires, un capteur de distance et des circuits électroniques de commande. Dans un mode de réalisation, la puissance optique des lentilles remplies de fluide peut être ajustée de façon à régler la longueur focale associée à la loupe binoculaire. Le capteur de distance peut être utilisé pour déterminer une distance entre la loupe binoculaire et un échantillon, pendant qu'un dispositif de commande compare la distance mesurée à la puissance optique actuelle de la ou des lentilles remplies de fluide, hermétiquement scellées. Le dispositif de commande peut transmettre des signaux à un ou à plusieurs actionneurs couplés à une ou à plusieurs lentilles remplies de fluide, hermétiquement scellées, afin de changer la puissance optique de la ou des lentilles remplies de fluide, hermétiquement scellées, sur la base de la comparaison.

Patent CA-2824556-C (CA)
Inventor: DING FRANK
IPC: B01D53/04

Granted: 2019-04-02
Abstract: A conformal filter is disclosed having a plurality of sorbent beds oriented perpendicular to an inner side surface of the filter which conforms to an adjacent surface, such as a wearer's face when attached to a respirator. The inner side of the filter may approximate the curved shape of an interfacing surface. Because the sorbent beds are oriented perpendicular to the inner side surface, a conformal configuration can be achieved without bending the sorbent beds and while keeping constant bed residence time throughout the entire cross-sectional area of the air flow, thus enforcing even air distribution. Reduced bed depth is also achieved through this configuration which consequently reduces the overall pressure drop through the filter. Other embodiments are described and claimed.
