Latest Patents

One of Goldis's latest patents is an ink delivery system for high-speed printing. This system is designed for high throughput commercial inkjet printing devices. It features a high-speed ink ejection printhead with a large number of nozzles and an ink flow design that improves printhead cooling. The design achieves high ink ejection rates by utilizing a very short inlet channel length, made possible by maintaining a constant distance from the edge of the printhead. Additionally, the array of nozzles is positioned at an angle relative to the normal scan direction. The system also includes an impinging ink flow to limit the printhead's temperature, a bubble collection chamber to extend the printhead's life, and a pressure regulator for controlled ink pressure during peak usage.

Another significant patent by Goldis is a capacitive ink level detection sensor. This sensor detects the amount of residual ink remaining within an ink container of an inkjet cartridge by measuring the capacitance of the air dielectric between the ink bag and the ink cartridge. This innovation enhances the functionality of inkjet cartridges by providing accurate ink level readings.
