The charge director is to charge the chargeable dispersant molecules. | 06-30-2016 |
20160187757 | METHOD AND APPARATUS FOR ELECTRONICALLY DISPLAYING INFORMATION - Embodiments of the present invention relate to a mass resolving aperture that may be used in an ion implantation system. Embodiments of the present invention relate to a mass resolving aperture that is segmented, adjustable, and/or presents a curved surface to the oncoming ion species that will strike the aperture. Embodiments of the present invention also relate to the filtering of a flow of charged particles through a closed plasma channel (“CPC”) superconductor, or boson energy transmission system. | 06-30-2016 |
20160187758 | MULTI-COLOR ELECTRO-OPTIC DISPLAYS - An electro-optic display comprising at least two separate layers of electro-optic material, with one of these layers being capable of displaying at least one optical state which cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another. | 06-30-2016 |
20160187759 | MATERIALS FOR USE IN ELECTROPHORETIC DISPLAYS - An electrophoretic medium comprises an electrophoretic layer, a layer of lamination adhesive and a polymeric layer disposed between the electrophoretic layer and the lamination adhesive layer, the polymeric layer being impermeable to the fluid. A second form of electrophoretic medium has a layer of a complex of an alkali metal and a polymer in contact with the electrophoretic layer. A third form of electrophoretic medium comprises a plurality of discrete droplets of internal phase in a binder, and further comprises a salt. | 06-30-2016 |
20160377950 | METHOD AND APPARATUS FOR A DRY PARTICLE TOTALLY INTERNALLY REFLECTIVE IMAGE DISPLAY - A total internal reflection image display comprised of dry electrostatically mobile particles composed of a solid material stably floating as a dispersant in a gas and exhibiting a high fluidity in an aerosol state may be sealed between the transparent sheet capable of total internal reflection such as comprising a plurality of transparent convex or hemi-spherical protrusions and the rear support, partition walls and the dry particles may be moved by application of a voltage bias. A method of manufacture is described comprising of the steps of forming partition walls, filling with dry particles, sealing the particles into cells or compartments. | 12-29-2016 |
20160377951 | METHOD FOR MECHNICAL AND ELECTRICAL CONNECTION TO DISPLAY ELECTRODES - An electro-optic display may comprise a front electrode having a first opening defined therein, a rear electrode having a second opening defined therein, an electro-optic layer between the front and rear electrodes and a rigid conductive component passing through the first and second openings and electrically contacting the front electrode but not the rear electrode. | 12-29-2016 |
