Pedro P. VERGARA GONZALEZ has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11874456
    Abstract: The presently disclosed subject matter relates to electromechanical systems and devices, and more particularly to electromechanical systems for implementing reflective devices for displays, sensors, and authentication solutions. In some embodiments a reflective device includes a thin film transistor layer and a plurality of reflective elements positioned approximately parallel to the thin film transistor layer. The plurality of reflective elements is electrically coupled with the thin film transistor layer. Each reflective element is configured for controlling a reflectance parameter of the reflective element based on a first voltage applied to the reflective element by the thin film transistor. In other embodiments, a reflective element includes a transparent substrate and a plurality of polymer-air pair layers positioned approximately parallel position to the transparent substrate.
