A method, an article and a kit for the detection and visual indication of contact with or exposure to a polyhydroxyaromatic skin irritant found in the sap of a plant is provided herein. The article incorporates a colorless leuco dye that undergoes an instantaneous visible color change when contacted with or exposed to a polyhydroxyaromatic skin irritant in the sap of a plant or on a subject. This color change is an indication that contact with or exposure to a polyhydroxyaromatic skin irritant has occurred. Polyhydroxyaromatic skin irritants found in the sap of plants include those found in poison ivy, poison oak, poison sumac, poison dogwood, mango tree, cashew tree and lacquer tree. The leuco dye of the invention is Pergascript Red I-6B (1(3H)-isobenzofuranone,3,3-bis(2-methyl-1-octyl-1H-indol-3-yl)-).

Novel addressing schemes for controlling electronically addressable displays include a scheme for rear-addressing displays, which allows for in-plane switching of the display material. Other schemes include a rear-addressing scheme which uses a retroreflecting surface to enable greater viewing angle and contrast. Another scheme includes an electrode structure that facilitates manufacture and control of a color display. Another electrode structure facilitates addressing a display using an electrostatic stylus. Methods of using the disclosed electrode structures are also disclosed. Another scheme includes devices combining display materials with silicon transistor addressing structures.

Multi-color electrophoretic displays and materials for making the same

Disclosed herein are novel electrophoretic displays and materials useful in fabricating such displays. In particular, novel encapsulated displays are disclosed. Particles encapsulated therein are dispersed within a suspending, or electrophoretic, fluid. This fluid may be a mixture of two or more fluids or may be a single fluid. The displays may further comprise particles dispersed in a suspending fluid, wherein the particles contain a liquid. In either case, the suspending fluid may have a density or refractive index substantially matched to that of the particles dispersed therein. Finally, also disclosed herein are electro-osmotic displays. These displays comprise at least one capsule containing either a cellulosic or gel-like internal phase and a liquid phase, or containing two or more immiscible fluids. Application of electric fields to any of the electrophoretic displays described herein affects an optical property of the display.

Encapsulated electrophoretic displays and methods and materials for making the same

An electrophoretic display having a protective electrode that reduces the degradation of the display caused by mechanical or electrochemical action. The electrode can include a protective layer that reduces the mechanical or electrochemical damage to a transparent conductive electrode. The protective electrode can be a vapor permeable electrode that is a reticulated electrically conductive structure, such as a metal screen or wire mesh, or a reticulated structure coated or impregnated with a conductive material. The protective electrode can include a layer that protects the display media from physical abrasion or removal by mechanical action, while allowing the application of an electric field to cause the display to be addressed.

Protective electrodes for electrophoretic displays

A process for creating an electronically addressable display includes multiple printing operations, similar to a multi-color process in conventional screen printing. In some of the process steps, electrically non-active inks are printed onto areas of the receiving substrate, and in other steps, electrically active inks are printed onto different areas of the substrate. The printed display can be used in a variety of applications. This display can be used as an indicator by changing state of the display after a certain time has elapsed, or when a certain pressure, thermal, radiative, moisture, acoustic, inclination, pH, or other threshold is passed. In one embodiment, the display is incorporated into a battery indicator. A sticker display is described. The sticker is adhesive backed and may then be applied to a surface to create a functional information display unit. This invention also features a display that is both powered and controlled using radio frequencies. It describes a complete system for controlling, addressing, and powering a display. The system includes an antenna or antennae, passive charging circuitry, and active control system, a display, and an energy storage unit. There is also a separate transmitter that provides the remote power for the display. The system is meant to be used anywhere it is useful to provide intermittent updates of information such as in a store, on a highway, or in an airport. A tile-based display allowing a modular system for large area display is created using a printable display material.

A method, and product thereof, is described for reducing the amount of oil absorbed into a food during hot oil frying. The method involves coating the food, prior to deep fat frying, with a protein latex which forms a layer of hydrophobic protein having excellent barrier properties to hot oil.

Potato and other food products coated with edible oil barrier films

Texturized oils and oil-continuous emulsions are prepared by combining liquid oils with edible polyester polymers. The resulting texturized oils and emulsions are gelled substances having a fat-like consistency which approximates the viscoelastic properties of solid fats, such as butter, margarine or hydrogenated vegetable oils, but contain no saturated fats. These texturized oils and emulsions can be used as a substitute for solid fats in food products and to make high-quality spreads containing reduced amounts of saturated fat.
