  • Patent number: 12560024
    Abstract: A laminate which can serve as either a smart window or a smart mirror is formed using first and second substrates coated with transparent first and second electrodes which are separated by foraminous layer and a third grid-like linear electrode insulated from the first and second electrodes. The foraminous layer includes spacers defining a cell space which is filled with a colloidal ink having first and second particles. The first particles have a positive charge and a first color and second particles having a negative charge and a second color different from the first color. By altering the voltages of the first, second and third electrodes, one can achieve different light transmission characteristics which, for example, can alter the color temperature of the light transmitted through the laminate or enhance reflective colors.

  • Patent number: 12545752
    Abstract: Embossing resins, methods of manufacturing such resins, and electrokinetic display system, which includes display cells containing such resins. The resins include a fluoropolymer in weight percentage 5%-60%, a difunctional diluent in weight percentage 0-30%, a monofunctional diluent in weight percentage 0-40%, a urethane diacrylate or functionalized nanoscale material, e.g., a functionalized urethane material, in weight percentage 5-50%, a photoinitiator in weight percentage 0.5-5%, and a surfactant in weight percentage less than 0.5%. The difunctional diluent may be Hexanediol Diacrylate, and the monofunctional diluent may be a monofunctional hydrocarbon. The resins are made by identifying a target index of refraction for a cured state thereof, and combining together, by weight percentage, the constituent components to produce the liquid state version of the embossing resin having a desired composite index of refraction.

  • Patent number: 12422734
    Abstract: The present invention is a window pane assembly system and method utilizing locking a locking system for easy insertion of a second window pane and an electro kinetic strip or film on these window panes. These electrokinetic strips and films have the capability to do many things on the window panes like changing the opacity of the windows and allowing certain levels of light through the window. The use of this technology can create more opportunities for creating advertisements on window surfaces, storing energy or repelling solar energy for building temperature management and energy savings. The electrokinetic film can be used with a remodel of window panes or the electrokinetic strips and films can be built into new window panes. With the ability of the electrokinetic devices to allow certain levels of light in, there is the opportunity for many more technological advancements on the window panes.
