  • Patent number: 9341916
    Abstract: An electro-optic display comprising at least two separate layers of electro-optic material, with one of these layers being capable of displaying at least one optical state which cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.

  • Patent number: 5623017
    Abstract: A method of forming a thermodynamically stable transparent product by combining (i) water; (ii) a volatile cyclic methyl siloxane or volatile linear methyl siloxane; and (iii) a silicone polyether surfactant. The amounts of each component, the particular type of silicone polyether surfactant used, and the order of addition of the components, influence the type of product obtained, and these factors are such that the composition forms an optically clear gel. The gel is useful in personal care products such as cosmetics and antiperspirants.
