  • Patent number: 12339556
    Abstract: Disclosed are a color-changing polymer composition, an ion-conductive composition, and a transparent electrode layer composition for a painting-type spray coating process, and an electrochromic device including the same. The color-changing polymer composition for an electrochromic device includes an amount of about 5 to 30 wt % of a color-changing material, an amount of about 0.01 to 1 wt % of ferrocene, an amount of about 10 to 30 wt % of a polymer matrix, an amount of about 0 to 70 wt % of an ion-conductive material, and an amount of about 1 to 10 wt % of a POSS (polyhedral oligomeric silsesquioxane) derivative, based on the total weight of the composition.

  • Patent number: 12292666
    Abstract: A form of a color-changeable plastic includes: a first conductive electrode layer; a color change layer disposed on the first conductive electrode layer, configured to cover a top surface of the first conductive electrode layer, and made of a substance that changes color depending on whether a voltage is applied; a second conductive electrode layer disposed on the color change laver, configured to cover a top surface and side surfaces of the color change layer, and configured to change the color of the color change layer with the first conductive electrode layer when the voltage is applied; and a conductive guide disposed at at least one of the first conductive electrode layer or the second conductive electrode layer, and configured to guide a movement of electrons and a color change direction of the color change layer when the voltage is applied.

  • Publication number: 20250054042
    Abstract: Systems, methods, and computer-readable storage media for predicting user interest, and more specifically to defining user interest based on user expressions of intent. The system can receive a list of items, where each item in the list of items has a similar purpose and can be substituted with other items in the list of items, and item content elements associated with items in the list. The system can then identify websites with content that is relevant to the item content elements associated with the list based on relevancy, and identify at least one user that accessed one of the websites, resulting in at least one interested user. The system can then generate, for each user in the set of at least one interested users, a user intent and modify a previously planned interaction with the each user based on the user intent score.
