摘要： A gyricon or rotating-particle display having an "eggcrate" substrate. The display includes a substrate having a cavity-containing matrix whose cavities are disposed substantially in a single layer and are arranged within the matrix substantially in a geometrically regular pattern, and a plurality of optically anisotropic particles disposed in the cavities in the substrate, with each cavity containing at most one of the optically anistropic particles. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; the particle, when in its rotatable disposition, is not attached to the substrate. Each particle, for example, can have an anisotropy for providing an electrical dipole moment, the electrical dipole moment rendering the particle electrically responsive such that when the particle is rotatably disposed in an electric field while the electrical dipole moment of the particle is provided, the particle tends to rotate to an orientation in which the electrical dipole moment aligns with the field. The single layer of cavities can be substantially planar, and the geometrical pattern of cavities can be a two-dimensional array pattern in the plane of the layer, such as a hexagonal, rectangular, or rhomboidal array pattern. The substrate can further include first and second members between which members the matrix is disposed; at least one of the members can include an optically transmissive window through which a flux of optical energy can pass so as to be incident on the particles.

摘要： An apparatus for fabricating hemispherically bichromal balls, comprising a separator member having opposing first and second surfaces located and an edge region in contact with both surfaces, and delivery means for flowing first and second colored hardenable liquid material over the first and second surfaces, respectively, so that the liquid materials arrive at the edge at substantially the same flow rate and form a reservoir outboard of the edge region. The reservoir comprises side-by-side regions of different colors which do not intermix. Further means is provided for propelling the first and second liquid materials away from the separator member and out of the reservoir into a fluid medium as a plurality of side-by-side bichromal streams whose forward ends become unstable and break up into droplets which form into spherical balls, each of the balls comprising hemispheres of differently colored hardenable liquid, and means for collecting the bichromal balls.

摘要： A display is provided with an insulative layer whose electrical properties have been selected so that the display can be addressed by the effects of triboelectrically generated charges and thus requires no stylus or special writing utensil. Thus, the display can be addressed by dragging a finger across the display. Alternately, the display is provided with an insulafive layer whoes electrical properties have been selected so that the display is addressed with a stylus and is immune from the effects of stray riboelectrically generated charges.

摘要： An improved electric paper which allows it to form an image from a light image rather than from an applied electric field. The prior art embodiment had a number of rotatable balls imbedded in a plastic substrate. Each ball had hemispheres that had different electrical characteristics, and were colored differently. Under the influence of an image in the form of an electrical field, the balls would selectively rotate to form a permanent visible image, whereupon the field could be removed. This invention has two conductive surfaces to provide a uniform electric field across the substrate, and then exposes the substrate to light which selectively changes the electrical characteristics of one of the two hemispheres, resulting in the rotation of the selected balls to form the image.

摘要： There is described an optical-effect-producing medium comprising a carrier medium (1) containing or comprising pigment particles (10) having at least one optically responsive pigment or dye (100) that responds to incident electromagnetic radiation of at least a selected excitation wavelength or wavelength band (λEX) by producing an optical response in the visible or near-visible spectrum. A refractive index (n1) of the carrier medium (1) and a refractive index (n2; n3) of the pigment particles (10) are selected to maximise the amount of incident electromagnetic radiation reaching the said at least one optically responsive pigment or dye (100). Also described is the use of such optical-effect-producing medium to produce an optically responsive feature, especially for security, authentication and/or identification purposes, as well as objects comprising such an optically responsive feature.

摘要： A rotating element for use in an electric paper system in which the rotating element may be either substantially cylindrical or substantially spherical in shape and comprises at least three portions. Each portion has an associated optical modulation characteristic and the optical modulation characteristics of at least one portion are different from the optical modulation characteristics of at least one other portion. One of the portions is capable of being permanently magnetized. The rotating element also has an anisotropy for providing an electrical dipole moment. The electrical dipole moment renders the element electrically responsive such that when the rotating element is rotatably disposed in an electric field while the electrical dipole moment of the rotating element is provided, the rotating element tends to rotate to an orientation in which the electrical dipole moment aligns with the field.
