    Abstract: A gyricon or twisting-particle display based on spheroidal optically anisotropic particles disposed in a substrate. The particles are preferably aligned parallel to one another and packed close together in a monolayer. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; for example, the particles can already be rotatable in the substrate, or can be rendered rotatable in the substrate by a nondestructive operation performed on the substrate. In particular, the substrate can be made up of an elastomer that is expanded by application of a fluid thereto so as to render the particles rotatable therein. A particle, when in its rotatable disposition, is not attached to the substrate. The close-packed monolayer configuration of particles provides excellent brightness characteristics and relative ease of manufacture as compared with certain other high-brightness gyricon displays.

    Abstract translation: 基于设置在基板中的球状光学各向异性粒子的陀螺仪或扭曲粒子显示器。 颗粒优选彼此平行对准并且以单层紧密堆积在一起。 可以实现每个颗粒的可旋转布置,同时将颗粒设置在基板中; 例如,颗粒可以在衬底中可以旋转,或者可以通过在衬底上进行的非破坏性操作而在衬底中转动。 特别地,基材可以由弹性体构成,弹性体通过向其中施加流体而膨胀,以使颗粒在其中可旋转。 当颗粒处于其可旋转的位置时,未附着到基底上。 与某些其他高亮度陀螺显示器相比,颗粒的紧密单层构造提供了优异的亮度特性和相对的制造容易度。

    Abstract: Methods and systems consistent with the present invention can be used to assemble composite rotatable-element components and can be used to form a laminate substrate system, and use a plurality of rotatable-element components or rotatable-element component material of two classes. Each class is defined by a common response or responses to incident electromagnetic radiation of interest. The method for assembling a composite rotatable-element component comprises: dispersing a plurality of rotatable-element components of a first class to first preferred positions on a first carrier; dispersing a plurality of rotatable-element components of a second class to second preferred positions on a second carrier; performing a first manipulation of the first carrier and the second carrier such that one of the plurality of rotatable-element components of a first class and one of the plurality of rotatable-element components of a second class touch at a first contact point; and performing a second manipulation of the rotatable-element components that touch such that they bond to form a composite rotatable-element component. The method for assembling a laminate substrate further comprises: performing a third manipulation of the first carrier and the second carrier such that they touch at a set of second contact points; and performing a fourth manipulation of the first carrier and the second carrier such that they bond to form the laminate substrate.

    Abstract: 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 ant 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.

    Abstract: A gyricon or twisting-particle display based on nonspheroidal (e.g., substantially cylindrical) optically anisotropic particles disposed in a substrate. The particles can be either bichromal or polychromal cylinders, preferably aligned parallel to one another and packed close together in a monolayer. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; for example, the particles can already be rotatable in the substrate, or can be rendered rotatable in the substrate by a nondestructive operation performed on the substrate. In particular, the substrate can be made up of an elastomer that is expanded by application of a fluid thereto so as to render the particles rotatable therein. A particle, when in its rotatable disposition, is not attached to the substrate. The close-packed monolayer configuration of particles provides excellent brightness characteristics and relative ease of manufacture as compared with certain other high-brightness gyricon displays. The substrate containing the cylinders can be fabricated with the swelled-elastomer techniques known from spherical-particle gyricon displays, with a simple agitation process step being used to align the cylinders within the sheeting material. Techniques for fabricating the cylinders are also disclosed.

    Abstract: INK JET ELECTROHYDRODYNAMIC EXCITER An ink jet printing system is disclosed of the type wherein selected droplets from a continuous stream of droplets are charged and deflected toward a target. The droplet placement on the target is determined by the amount of charge. The system uses an electrohydrodynamic (EHD) exciter to generate the continuous stream. The exciter is composed of one, two, three or more pump electrodes of a length equal to about one half the droplet spacing. The multiple pump electrode embodiments are spaced at intervals of multiples of about one half the droplet spacing or wavelength.
