Title: Innovations of William J West
Introduction
William J West is a notable inventor based in Los Altos, California. He has made significant contributions to the field of ink-jet printing technology. With a total of 8 patents to his name, West has developed innovative solutions that enhance the functionality and efficiency of ink-jet systems.
Latest Patents
One of his latest patents is focused on back pressure control in ink-jet printing. This system is designed to manage the back pressure in the reservoir of an ink-jet pen. It includes a pump for removing air from the reservoir and a vacuum regulator to ensure that the back pressure does not exceed levels that could cause the print head to fail. Another significant patent is a method and system for remote-sensing ink temperature and melt-on-demand. This invention regulates the temperature of hot melt ink by detecting light reflected from a phase change material adjacent to the ink. A closed loop control signal is generated based on the intensity of the reflected light, which is then applied to a heater element for precise temperature control. Additionally, this system provides an ink level indication signal processed in a closed loop servo system to maintain optimal ink levels during the operation of an ink jet printhead.
