    摘要： The present invention discloses resistive touch sensors that incorporate microstructured conductive layers. When local electrical contact is made between the microstructured conductive layer and an opposing conductive layer due to a touch input, the resulting signal can be used to determine the location of the touch. The microstructures can be used to penetrate a solid, deformable filler material disposed between the conductive layers, for example to provide more transmission of light through the sensor. The microstructures can also provide additional functionalities such as z-axis sensitivity, image direction, light control, light extraction, and so forth.

    摘要： The present invention provides a switchable pressure activated electronic device. The switchable electronic device includes a composite material disposed between two conductors. The composite material electrically connects the two conductors when pressure is applied between them, and electrically isolates the two conductors when pressure is not applied between them. The composite includes conductive particles at least partially embedded in an insulating material. The conductive particles are disposed so that substantially all electrical connections made between the first and second conductors are through single particles.

    摘要： A beaded light dispersing film has a substrate layer, and an optically transparent layer, having a predetermined thickness, disposed over a side of the substrate layer. Optically transmitting beads are arranged to penetrate at least partially into the transparent layer to define clear apertures at interfaces between the beads and the transparent layer. The bead radius is greater than the predetermined thickness. An absorbing layer is disposed on the transparent layer, in interstices between the beads. A method of manufacturing the film includes disposing optically transparent beads partially in an optically transparent layer disposed over a transparent substrate layer. The optically transparent layer has a thickness less than half a diameter of a transparent bead. An absorbing layer overlies the optically transparent layer.

    摘要： The present invention provides a beaded rear projection screen that has performance properties such as gain and viewing angle that can be tuned by using a mixture of two or more types of microbeads having different refractive indices and varying the mixture. The present invention further provides methods of selecting microbeads and the construction of the screen so that transmission through the screen can remain sufficiently high throughout the range of tunability.

    摘要： An optically dispersing film for a rear projection system includes reflecting surfaces disposed so as to reflect light passing therethrough into at least one dispersion plane. The reflecting surfaces are formed by structures, of a first refractive index, disposed within a layer of material having a second refractive index. The structures have light absorbing bases at the viewing side of the film. In some embodiments, the reflecting surfaces are disposed at one or more angles so as to reflect light into a number of different directions. In other embodiments, the layer of material having the second refractive index includes diffusing particles that diffuse the light. The film permits the asymmetric dispersion of image light in a rear projection system, so that the light may be selectively directed towards the viewer.

    摘要： A method of selectively patterning a structured substrate without using a mask is disclosed. The method includes the steps of providing a surface having a plurality of protrusions, coating the surface with a filler material thick enough so that the protrusions are covered, and planarizing the filler coating. The filler material is thereafter partially removed in a uniform fashion to expose only those portions of the protrusions to be modified. After modifying the protrusions by, for example, deposition or etching, the remaining filler material may be removed, resulting in a structured substrate selectively modified or patterned at its protrusions.
