Latest Patents

Catherine holds a patent for a "Method and apparatus for determining the contact angle of a drop of liquid." This invention involves a support that holds a substrate horizontally, allowing a drop of liquid to be placed on it. A source of light, in conjunction with a collimator, directs a primary beam of parallel light perpendicularly to the substrate. The interaction between this beam and the drop, along with the substrate, produces a secondary beam that is intercepted by a receiver surface. The contact angle can be deduced from the illuminated zone on the receiver surface. This patent showcases her innovative thinking and technical expertise.
