His innovative work has led to the development of a patented system that enhances the quality of printing and scanning processes.

Latest Patents

Dan holds a patent for a "Calibrating system for a compact optical sensor." This compact optical sensing system is utilized in hardcopy devices for scanning and/or printing images, such as inkjet printing technology in desktop printers and photographic printers found in grocery and variety stores. The system employs several light-emitting diodes (LEDs) to illuminate a sheet of print media, while one or more photodiodes receive the light reflected from the sheet. The photodiode generates signals in response to the light received, which the hardcopy device uses to adjust printing parameters for optimal print quality. The design incorporates a chip-on-board process, allowing for a compact arrangement of at least four LEDs (blue, green, red, and soft-orange) in a space smaller than that occupied by a factory-made, single-packaged LED. Additionally, a calibrating system utilizes a white target covered by a windowed door, which is opened and closed by a printhead carriage.
