New transport speed, tension, and framing control approach

Below is a system diagram showing how I intend to control film speed, tension, camera shutter (framing) and backlight flash. It is not a scale drawing, and only shows the system components in the context of the tasks they need to perform. In particular, the film gate area is only conceptual, but it is my intention to keep the film path as straight as possible to reduce drag and reduce film stress. The heart of the system is a Phase Locked Loop (PLL) device that will probably be implemented in...
