Latest Patents
One of his latest patents is a multiple projection optics slide projection apparatus. This innovative slide projector features two image-projection systems that operate with a circular slide tray. The design allows slides to pass directly between the slide tray and either of two slide gates. The slide gates move between positions to acquire and release slides, as well as to project them onto a screen. The projector includes a slide lifter, a slide tray lock, and slide clamps on each slide gate, all operated in a specific sequence to ensure proper handling of the slides. The central hub of the slide tray is independently driven, and sensors continuously detect the positions of the lifter, slide gates, and slide tray. Additionally, a front-end assembly incorporates lenses that move laterally and vertically, maintaining parallel longitudinal axes for precise image alignment.
