Latest Patents
One of her latest patents is a "Drop quality control system for jet printing." This invention involves a method and apparatus for controlling the flight time and composition of a marking fluid used in a continuous jet marking system. A three-way valve allows for switching between fresh ink and system ink supplies. The system periodically compares the pressure required to maintain a constant drop flight time, enabling adjustments to be made to restore viscosity to desired values.
Another significant patent is the "Impact-valve printhead for ink jet printing." This invention features an ink jet chamber that communicates with an ink reservoir through an opening in a diaphragm plate. The chamber includes a nozzle for ejecting ink on demand. A mass, such as a ball, is driven into the diaphragm plate, pressurizing the ink in the chamber to eject a droplet from the nozzle. This design allows for the construction of large arrays, enhancing the capabilities of ink jet printing.
