Title: Francesca A Barrientos: Innovator in Paper Transport Systems
Introduction
Francesca A Barrientos is a notable inventor based in Berkeley, CA (US). She has made significant contributions to the field of paper transport systems, holding a total of 4 patents. Her work has been instrumental in enhancing the efficiency and functionality of copying and printing technologies.
Latest Patents
Among her latest patents is the "Single drive nip sheet buffering system using independently driven rolls." This innovative paper transport system includes an apparatus designed to control the movement of sheets along a predetermined course, providing effective sheet buffering. The system features first and second friction surfaces that move in orbital paths, defining a nip through which the paper sheets pass. The independently controlled movement of these surfaces allows for optimized performance, ensuring that the first friction surface has a higher coefficient of friction with the paper sheets than the second surface.
Another significant patent is the "Automatic copy sheet selection device." This device automatically selects the appropriate type of copy sheet based on the weight of the original document without requiring coded control sheets or operator input. A paper weight sensor in the document handler determines the weight of each original sheet and sends a signal to a programmable controller, which selects the correct copy sheet feed tray based on preprogrammed parameters.
