Latest Patents
One of his latest patents is for an electrofluidic display and methods for making it. This invention outlines a method for manufacturing a freestanding film that includes a population of through holes, which cumulatively total at least 1% of the film area. The film's design ensures that the standard deviation of hole diameters is less than 25% and maintains a thickness of less than 25 micrometers. The process involves using a carrier substrate, a photo-curable material, and a release agent, allowing for selective curing and removal of material to create the desired pattern of holes.
Another significant patent is for energy-efficient shading systems for windows. This shading assembly can be configured into three selectable states. The first state allows more than 40% of solar light to pass through while reflecting over 35% of solar heat. The second state blocks more than 75% of solar light while transmitting over 50% of solar heat. The third state transmits more than 50% of both solar light and heat, demonstrating versatility in energy management.
