  • Publication number: 20050018273
    Abstract: In electrophoretic media, it is advantageous to use pigment particles having about 1 to 15 per cent by weight of a polymer chemically bonded to, or cross-linked around, the pigment particles. The polymer desirably has a branched chain structure with side chains extending from a main chain. Charged or chargeable groups can be incorporated into the polymer or can be bonded to the particles separately from the polymer. The polymer-coated particles can be prepared by first attaching a polymerizable or polymerization-initiating group to the particle and then reacting the particle with one or more polymerizable monomers or oligomers.

  • Patent number: 6847943
    Abstract: The method discloses a rule-based decision process which formulates an investment strategy in terms of short term debt, long term debt, short term equity, and/or long term equity for a variety of property types and geographic markets. The first phase of the method achieves a visual representation of the condition of each of a selected territory's major markets, showing market direction and volatility determined on the basis of commercially available market research data which has been adjusted by the investing entity in light of actual local experience in the market. The second phase deals with the implications of the first phase results on four possible alternative investment types, namely, short term debt, long term debt, short term equity, and/or long term equity. This is accomplished by formulating a set of decision rules which enable the individual investors of the investing entity to uniformly evaluate specific types of investment for each property type in a respective market area.

  • Publication number: 20050007336
    Abstract: 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.

The electronic display includes a nonemissive electro-optic medium; and a light transmissive element. Light transmitted through the light transmissive element illuminates the display medium. The propagation of light that is directed through the light transmissive element towards the microencapsulated electrophoretic display medium is substantially undeflected at the interface between the surface of the light transmissive element and the microencapsulated electrophoretic display medium. A reflector is included for directing light from the light source through the light transmissive element.
