The present invention is a chromatic-emphasis hybrid-diatonic leverless keyboard configured to provide an extension, duplication, or representation of both heptatonic and pentatonic keys on the leverless keyboard. The extension enables the user to shift the physiological center of gravity for the keyboard to the area where pentatonic and heptatonic keys share space and are more isomorphic, thus assisting in gaining and applying understanding of the chromatic equality of the twelve tonalities in standard equal temperament, and in gaining and applying understanding of the one-dimensional nature of music.

Chromatic-emphasis hybrid-diatonic leverless keyboard

An apparatus and method for solution coating layers onto a substrate of an electronic device. A slot die coater in conjunction with a vacuum assist device is used in priming, coating and cleaning stations to produce thin layers having performance advantages over competing technologies.

Apparatus and method for solution coating thin layers

Methods for fabrication of organic electronic devices are described.

Methods of fabricating organic electronic devices

The present invention relates to electrically conductive polymer compositions, and their use in electronic devices. The compositions contain a semi-aqueous dispersion of at least one electrically conductive polymer doped with at least one highly-fluorinated acid polymer, non-conductive oxide nanoparticles, at least one high-boiling organic liquid, and at least one lower-boiling organic liquid.

Electrically conductive polymer compositions for coating applications

There is provided a process for forming a contained second layer over a first layer, including the steps:

Process for making contained layers and devices made with same

There is provided a process for forming a contained second layer over a first layer. The process comprises forming the first layer having a first surface energy and then treating the first layer with a photocurable surface-active composition which is a fluorinated ester or fluorinated imide of an &#x3b1;,&#x3b2;-unsaturated polyacid; exposing the photocurable surface-active composition patternwise with radiation resulting in exposed areas and unexposed areas; developing the photocurable surface-active composition to remove the unexposed areas resulting in a first layer having untreated portions in the unexposed areas and treated portions in the exposed areas, where the treated portions have a second surface energy that is lower than the first surface energy; and forming the second layer on the untreated portions of the first layer. There is also provided an organic electronic device made by the process.

Process and materials for making contained layers and devices made with same

A process of forming an electronic device is disclosed. An organic device layer is formed. The organic device layer includes a charge-selective material and a radiation sensitizer and has a first electrical conductivity and a first surface energy. First portions of the organic device layer are selectively exposed to radiation. The electrical conductivity and surface energy of the first portions of the organic device layer are modified.

There is provided a portable substrate carrier enclosure. The carrier enclosure has a carrier support; a displaceable cover; spacers between the support and cover; a gas inlet; and a removable lid. There is also provided an assembly and a process for depositing an air-sensitive material onto a substrate using the portable substrate carrier enclosure.

Electronic device including a guest material within a layer and a process for forming the same

There is provided herein a process for forming an encapsulated electronic device. The device has active areas and sealing areas on a substrate. The process includes providing the substrate; forming a discontinuous pattern of a material having a first surface energy on at least a portion of the sealing areas; forming multiple active layers, where at least one active layer is formed by liquid deposition from a liquid medium having a surface energy greater than the first surface energy; providing an encapsulation assembly; and bonding the encapsulation assembly to the substrate in the sealing areas. Also provided are devices formed by the disclosed processes.

Process for forming encapsulated electronic devices

There is provided an essentially planar test substrate for non-contact printing. The substrate has a first layer having a first surface energy and having a planar measurement portion. A liquid containment pattern is over at least the measurement portion of the first layer. The liquid containment pattern has a second surface energy that is different from the first surface energy. The measurement portion of the first layer and the liquid containment pattern together are substantially planar.

Planar test substrate for non-contact printing

Emulsions comprising an active material, a solvent for dissolving the active material, and a wetting fluid, wherein the active material is sparingly soluble in the wetting fluid, are provided, and methods for making the same.

Organic compositions for depositing onto fluorinated surfaces

Organic electronic devices that include dummy electrodes are described, along with methods for using such devices.

Organic electronic device and processes for forming and using the same

A multilayer, photosensitive element comprising a coversheet, a photohardenable layer, a contiguous layer, an isolation layer, an adhesive layer, and a support, is described. The element is used for image reproduction.
