Latest Patents

- **Feedforward Control of Downstream Register Errors for Electronic Roll-to-Roll Printing System.** This invention combines feedforward control with conventional feedback control to compensate for register errors caused by variations in upstream printing-cylinder speeds. The approach aims to improve registration precision in continuous roll-to-roll printing and support manufacturing electronic devices using processes that previously could not be implemented reliably.

- **System and Method for Producing Flexible Dye-Sensitized Solar Cells by a Roll-to-Roll Printing Process.** This patent describes a continuous production system for making flexible dye-sensitized solar cells. Its process forms and sinters a titanium dioxide layer, applies dye, washes and dries the substrate, prints a gel electrolyte, and seals the assembly with another flexible conductive substrate. The system also describes controlling and recirculating the dye solution and managing the electrolyte layer to help prevent leakage.
