Abstract: Un giricon o dispositivo de representacion visual de partículas giratorias basado en partículas opticamente anisotropicas no esferoidales (por ejemplo, sustancialmente cilíndricas) dispuestas en un sustrato. Las partículas pueden ser cilindros bicromicos, de manera preferible alineados paralelos entre sí y estrechamente empacados juntos en una monocapa. Una disposicion giratoria de cada partícula se logra mientras las partículas sean dispuestas de este modo en el sustrato, por ejemplo, las partículas pueden girar fácilmente en el sustrato, o pueden hacerse girar en el sustrato por medio de una operacion no destructiva efectuada sobre el sustrato. En particular, el sustrato puede hacerse de un elastomero que se expanda mediante la aplicacion de un fluido a este para hacer que las partículas giren en él. Una partícula, cuando está en su disposicion giratoria, no está unida al sustrato. La configuracion de monocapa estrechamente empacada de partículas proporciona características de brillantez excelente y relativa facilidad de manufactura en comparacion con ciertos otros dispositivos de representacion visual giricon de alta brillantez. El sustrato que contiene los cilindros puede ser fabricado con la técnica de elastomero hinchado conocida para dispositivos de representacion visual giricon de partículas esféricas, con un proceso de agitacion de un solo paso cuando para alinear los cilindros dentro del material hoja. También se describen las técnicas para fabricar los cilindros.

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 bichromal 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: An electrohydrodynamic (EHD) exciter (3) is disclosed for promoting the formation of droplets (26) from a column (1) of electrically conductive fluid emitted under pressure from a nozzle (2). The exciter is composed of one, two, three or more pump electroes (8) (9) (10) of a length equal to about one half the droplet spacing (5). Multiple pump electrode embodiments are spaced at intervals of multiples of about one half the droplet spacing or wavelength (5). The exciter may be used in an ink jet printing system of the type wherein selected droplets (26) 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.

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.
