  • Patent number: 11436427
    Abstract: A generative attribute optimization (“GAO”) system facilitates understanding of effects of changes of attribute values of an object on a characteristic of the object and automatically identifying attribute values to achieve a desired result for the characteristic. The GAO system trains a generator (encoder and decoder) using an attribute generative adversarial network. The GAO model includes the trained generator and a separately trained predictor model. The GAO model inputs an input image and modified attribute values and employs the encoder and the decoder to generate a modified image that is the input image modified based on the modified attribute values. The GAO model then employs the predictor model to that inputs the modified image and generate a prediction of a characteristic of the modified image. The GAO system may employ an optimizer to modify the attribute values until an objective based on the desired result is achieved.

  • Publication number: 20220267667
    Abstract: A product includes a cell having a mixture comprising a solvent and colloidal nanoparticles. Each of the colloidal nanoparticles have a core and a shell surrounding the core. The cell also includes at least one electrode. A product includes a nanoparticle having a core and a shell. The core includes a luminescent material. The shell is silicon-based. A method includes applying an external stimulus to a cell containing a mixture comprising a solvent and colloidal nanoparticles for altering the brightness and/or color of an assembly of at least some of the colloidal nanoparticles. Each of the colloidal nanoparticles have a core and a shell surrounding the core.

  • Patent number: 10732480
    Abstract: According to one embodiment, a product is a mixture including a solvent and generally spherical colloidal nanoparticles, the colloidal nanoparticles each having a core and a shell surrounding the core, and an electrode. In addition, the mixture is characterized as having a transparency to light in a predetermined wavelength range, where the transparency increases as a voltage of the electrode increases.

  • Patent number: 9975178
    Abstract: In one embodiment, a process includes creating a mixture of an aqueous component, nanowires and nanoparticles, and a hydrophobic solvent and allowing migration of the nanowires to the hydrophobic solvent, where the nanoparticles remain in the aqueous component. Moreover, the nanowires and nanoparticles are in the aqueous component before the migration.
