Title: Mark S Barbour: Innovator in Fluid Ejection Technologies
Introduction
Mark S Barbour is a notable inventor based in Corvallis, Oregon. He has made significant contributions to the field of fluid ejection technologies, holding a total of 2 patents. His work primarily focuses on methods that enhance the efficiency and effectiveness of ejection devices.
Latest Patents
Barbour's latest patents include a method of ejecting fluid from an ejection device. This innovative method involves adding fluid to a firing chamber and passing a first amount of charge through a heating element. The first amount of charge causes the heating element to emit thermal energy, forming a vapor bubble that ejects fluid from the chamber. Additionally, a second amount of charge is passed through the heating element to emit thermal energy that is insufficient to eject fluid, optimizing the ejection process.
Another significant patent is related to asymmetric fluidic techniques for ink-jet printheads. This invention features a printhead apparatus with multiple ink drop generators. Each generator includes an orifice and a heating resistor, designed to create a rotational component in the ink fluid velocity during drop ejection. This innovative design reduces damage to the heating resistor, thereby extending its lifespan.
