Latest Patents
One of his latest patents is titled "Electrophoretic, high index and phase transition control of total internal reflection in high efficiency variable reflectivity image displays." This invention utilizes charged particles suspended in a medium, such as Fluorinert™ Electronic Liquid, to electrophoretically control total internal reflection (TIR) at a retro-reflective surface formed on a high refractive index material. The design incorporates prismatic structures that redirect ambient light from an overhead source toward a display image, enhancing the contrast of the reflective display. Additionally, a transparent planar waveguide illuminates the display with sequential flashes of red, blue, and green light, creating a full-color display. The patent also explores controlling TIR through vapor-liquid phase transitions and altering the absorption coefficient of materials using various methods.
Another significant patent is "Electrophoretic, dual refraction frustration of total internal reflection." This invention describes a display device and method that employs electrophoresis and/or dual prismatic surfaces to controllably frustrate TIR at the interface between materials with different refractive indices. In one embodiment, an array of solid dielectric light fibers is surrounded by an electrophoretic medium, allowing for the manipulation of light reflection based on electrophoretic activity. This innovative approach enables gapless control of the TIR phenomenon at flat surfaces.
