Latest Patents

Dennis Sand holds a patent for a "High-speed continuous linear film transport system." This invention establishes a stable, continuous, high-speed roll film media path between supply and take-up film reels. The design isolates a core transport path section from significant non-linear forces, enabling continuous, high-speed, high-accuracy scan line imaging of the media. The system features supply and take-up path segments that maintain open decoupling loops in the film media while accurately controlling speed, tension, and alignment. A microcontroller operates two motor-driven capstans to manage the film media's speed and tension, while optical sensors provide feedback to maintain the decoupling loops. This innovative design effectively isolates the film media from frictive, inertial, and skewing forces that could degrade imaging quality.
