Abstract: The invention relates to improved means for preventing buckling and therefore eversion of thin-walled, flexible, floppy gastrointestinal liners implanted in the digestive tract of an animal. The implantable devices include an anchor adapted for attachment within a natural body lumen and a thin-walled, floppy sleeve open at both ends and defining a lumen therebetween. A substantial length of the sleeve has material characteristics that result in the sleeve being prone to buckling and therefore eversion in the presence of retrograde pressures. Exemplary anti-buckling mechanisms provide an increased stiffness and/or an increased friction coefficient between the anchor and the proximal end of the sleeve to resist buckling and therefore eversion. In some embodiments, the anti-buckling mechanism is as a wire coupled along the substantial length of the sleeve.

Abstract: Organic electronic devices are fabricated by a process includes forming an organic layer including: placing a first liquid composition over a first portion of a surface of a substrate without a well structure connected to or adjacent the first portion of the surface of the substrate, i) the first portion of the surface of the substrate has a first surface energy, ii) the first liquid composition includes a first liquid medium and iii) the first liquid composition has a second surface energy that is higher than the first surface energy; and evaporating the first liquid medium while the first liquid composition overlies the first portion of the surface of the substrate.

Abstract: The invention relates to aqueous compositions comprising at least one doped conductive polymer, at least one co-solvent, and at least one metal cation selected from Group 1 metals or Group 2 metals or mixtures thereof.

Abstract: The invention relates to improved means for preventing eversion and subsequent obstruction of thin-walled, floppy gastrointestinal liners implanted in the digestive tract of an animal. The implantable devices include an anchor adapted for attachment within a natural body lumen and a thin-walled, floppy sleeve open at both ends and defining a lumen therebetween. A substantial length of the sleeve has material characteristics that result in the sleeve being prone to eversion in the presence of retrograde pressures. Exemplary eversion-resistant features provide an increased stiffness and/or an increased friction coefficient between the anchor and the proximal end of the sleeve to resist eversion. In some embodiments, the eversion-resistant feature includes an anti-buckling element, such as a wire coupled along the substantial length of the sleeve.

Abstract: Multilayer anode structures (104) for electronic devices (100) such as polymer light-emitting diodes are described. The multilayer anodes include a high conductivity organic layer (114) adjacent to the photoactive layer (102) and a low conductivity organic layer (112) between the high conductivity organic layer and the anode's electrical connection layer (110). This anode structure provides polymer light emitting diodes which exhibit high brightness, high efficiency and long operating lifetime. The multilayer anode structure of this invention provides sufficiently high resistivity to avoid cross-talk in passively addressed pixellated polymer emissive displays; the multilayer anode structure of this invention simultaneously provides long lifetime for pixellated polymer emissive displays.

Abstract: An electronic device configuration that prevents ambient moisture and oxygen from reacting with materials used in the fabrication of the devices and thus prevents ambient moisture and oxygen from deleteriously affecting device performance by use of an airtight enclosure comprising a porous drying agent.

Abstract: A substrate holder is provided to move a slide containing a microarray of biomaterial through a biomaterial analysis process. The substrate holder includes a substrate loader that allows loading of slides into the substrate holder with minimal contact to the slide, thereby minimizing the amount of contamination on the slide. The substrate holder can be used to transport a microarray of DNA through array fabrication, hybridization and analysis stations.

Abstract: An extendable shelf assembly is removably mounted on the slotted uprights of a display stand and comprises a shelf mounted on a shelf support, a shelf extender attached to said shelf and the shelf support and operable so that the shelf can be extended or retracted. A manually operable locking device permits the shelf to be extended or retracted and moved from one position to another when the locking device is released, the locking device retaining the shelf in its selected position when engaged. An angularly adjustable shelf support assembly which comprises a first mounting member with structure thereon for releasably attaching the member to a slotted upright and a second mounting member for attachment to the shelf to take the load thereof.
