Latest Patents

One of her latest patents is titled "Control method and apparatus for dispensing high-quality drops of high-viscosity materials." This invention focuses on a method and apparatus designed to dispense minute quantities of fluids, particularly highly viscous fluids, in a precise and repeatable manner without contact. The mechanism involves an impacting element that strikes a hardened insert on a flexible diaphragm, which deflects the insert into a jetting chamber. This action forces the viscous fluid through an outlet orifice, allowing for the controlled jetting of fluid in single drops.

Another notable patent is the "Viscous non-contact jetting method and apparatus." This invention details a method for dispensing minute quantities of highly viscous material from a jetting needle. The design includes a nozzle plate with a jetting chamber, where fluid enters from an inlet channel and is expelled by deforming the diaphragm to block the channel. This innovative approach allows for the precise expulsion of fluid drops from the needle.
