Latest Patents

One of his latest patents is a "Method and apparatus for cleaning inkjet cartridges." This invention focuses on removing surface contamination on flexible circuits for inkjet printer cartridges using pulsed laser irradiation in air. The method effectively eliminates contamination around and inside the tiny inkjet nozzles without damaging the flexible circuit. The cleaning mechanism relies on laser-induced ablation and fast momentum transfer from the laser beam to the contaminants. This technique offers high throughput and avoids the use of water and chemical solutions, which can be harmful to the circuits.

Another significant patent is the "Method of laser marking and apparatus therefor." This method is designed for marking hard transparent materials without causing microcracking. It involves directing irradiation onto the target material to ablate it and transfer it onto a markable surface. The process allows for different colors of marks depending on the target materials used, and the tone of the mark can be controlled as desired. The apparatus developed for this method enables real-time control, enhancing its practicality in various applications.
