Abstract: Methods and systems for designing an experiment using a computer to determine whether the experiment is a true experiment are described. These approaches allow a user who is unsophisticated in the complexities of true experimental design to design and deploy an experiment that produces substantially confound-free results and can be used to determine and quantify any causal relationship between independent and dependent variables. The computer may select one or more independent and/or dependent variables of the experiment or may assist the user in selection of independent and/or dependent variables. Formation of control and treatment groups, randomization and/or blocking to reduce the effects of confounding variables may be performed by the computer with or without input from the user.

Abstract: Edge-emitting organic light emitting diode (OLED) devices having optical microstructures and methods for fabricating them. The edge-emitting OLEDs include a substrate, an organic electroluminescent layer overlaying the substrate surface, and optical microstructures functioning as turning optics and separated from the OLEDs. The turning optics reflect and redirect the light from the edge-emitting OLEDs away from the top of the substrate, or through and away from the bottom of the substrate.

Abstract: The invention relates to organic electronic devices and methods of manufacture comprising at least two segments, each segment comprising an organic electronic light-emitting device wherein each segment is defined by peripheral edges; wherein each segment comprises a first electrical contact disposed on a first peripheral edge and a second electrical contact disposed on a different peripheral edge than the first electrical contact and the electrical contacts of each segment are joined in electrical communication with a conductive material.

Abstract: A microstructure to interact with electromagnetic waves by changing optical aspect in selected areas in response to an external signal, the microstructure comprising: a plurality of responsive elements, each responsive element capable of presenting at least two different optical aspects and changing between the optical aspects based on an applied external signal; a support substrate containing the responsive elements; and a plurality of assisting optical lenses each optically enlarging an image from the responsive elements associated with the assisting optical lens.

The electrode film has an array layer and an electrode layer, where the array layer provides a support structure for the electrode layer and electrically non conductive and in contact with the surface of the display panel and having. a plurality of mesa shaped segments where each mesa shaped segment has a top face and side walls extending downward from the top face. The electrode layer formed of an electrically conductive material coats the array layer and is exposed for contact by an electrical stimulus. The electrode layer is thicker on the top face than on the side walls, producing resistive bridges between adjacent top faces. The resistive bridges partially electrically isolate each electrode from the other electrodes in the electrode layer.

Abstract: Generally, the present invention relates to a display film and a method of making same, where the display uses electrically responsive, reflective particles disposed within a polymer matrix.

The invention is also directed to a display having particles selected from a production distribution of particles.

Abstract: A method improves the respondability of moveable structures in a display medium, such as a gyricon display. The inventive method includes heating the display and exercising the rotatable structures within the display by an application of an electrical field. Applying heat to the display enlarges the cavity surrounding each particle due to thermal expansion of the cavity and the bead rotation cycling jostles the particles loose. The inventive method enables a larger percentage of the particles to rotate to a greater degree thereby improving resolution of an image. Alternatively, heating and exercising can be accomplished by application of ultrasonics. In addition, degassing the fluid contained in the display enhances switching with heat and improves the rotatability of the structures.

Abstract: A segmented electrode film is used with a display panel, such as “gyricon” (or twisting particle) displays or other forms of electronic paper, such as particulate electrophoretic displays, which are available from E-Ink Corporation. The display panel has a viewing surface and a backside surface opposing the viewing surface. The electrode film can be on the viewing surface, in which case the electrode film must be transparent, or the backside surface or in a printer. The display panel comprises surrounding media containing particles which are responsive to changes in a magnetic field are optically anisotropic toward the viewing surface. The electrode film has an array layer and an electrode layer, where the array layer provides a support structure for the electrode layer. The array layer is electrically non conductive and in contact with the surface of the display panel.

Abstract: A retroreflective marking material which can be secured to a substrate, e.g., a firefighter's helmet, and then readily removed when desired, even after exposure to heat and flame. The material comprises a retroreflective layer made up of a layer of retroreflective elements in a binder layer, a fire resistant fabric, and a defined fire resistant adhesive on the rear of the fire resistant fabric. The adhesive adheres strongly to polycarbonate and can be stripped from polycarbonate after being held in a forced air oven at 260.degree. C. for 5 minutes. The marking material can contain fluorescent coloring agent(s) to afford good daylight visibility.
