Abstract: An organic electronic device includes a first electrode layer, an organic resistive layer coupled to the first electrode layer wherein the organic resistive layer defines at least three regions, an organic active layer coupled to the organic resistive layer, and a second electrode layer coupled to the organic active layer. Each of the at least three regions is characterized by one of the plurality of resistances and the plurality of resistances includes at least three discrete resistances that are different from one another.

Abstract: An electro-optic display is produced using a sub-assembly comprising a front sheet, an electro-optic medium; and an adhesive layer. An aperture is formed through the adhesive layer where the adhesive layer is not covered by the electro-optic medium, and the sub-assembly is adhered to a backplane having a co-operating member with the aperture engaged with a co-operating member, thus locating the sub-assembly relative to the backplane. In another form of electro-optic display, a chip extends through an aperture in the electro-optic medium and adhesive layer. In a third form, the aforementioned sub-assembly is secured to a backplane and then a cut is made through both backplane and sub-assembly to provide an aligned edge.

Abstract: The invention relates to compositions and methods for prion degradation, decontamination or disinfection. The composition comprises an oxidizing agent, one or more proteases and a surfactant such as an ionic surfactant/detergent. The method comprises contacting a prion contaminated entity with a prion-degrading composition comprising an effective amount of an oxidizing agent, an effective amount of at least one protease, and an effective amount of a surfactant. The components of the composition may be contacted with a prion-contaminated entity sequentially or simultaneously using an aqueous composition. Typically at least two different proteases are used for optimal efficacy. Preferably the oxidizing agent comprises peracetyl ions or a source thereof. The invention also relates to kits comprising the various reagents.

Abstract: The present invention relates to partially fluorinated (meth)acrylic polymers that can be blended with other (meth)acrylic polymers to provide enhanced surface properties.
Abstract: In the transition into the logarithmic range, not the entire bit width of the result linearly dependent upon the square of the value must be considered. Rather, it is possible to scale the result of a value with x bits such that a representation with less than x bits of the result is sufficient to receive the logarithmic representation based thereon. The effect of the scaling factor on the resulting logarithmic representation may be compensated for by adding or subtracting a correction value received by the logarithm function applied to the scaling factor to or from the scaled logarithmic representation without any loss of dynamics. This way, a method and an apparatus for creating a representation of a result linearly dependent upon a square of a value are provided so that the calculation is simple and/or possible with little hardware expenditure.

Abstract: In a space shuttle with a device for docking to a satellite, especially a communication or navigation satellite, at least two spreading elements in the form of lever spreaders are pivotally disposed at a retaining part of the docking device, which is concentric to a linkage. The lever spreaders have their proximal ends—relative to the space shuttle—provided with inward projections projecting inward towards the linkage, which inward projections engage in a recess formed in the linkage when the lever spreaders, spread apart to a defined opening angle by the cone of the linkage. When the linkage is retracted further, a pressure spring is compressed. At the same time, the lever spreader caught in the recess are retracted so far that the ends of the lever spreaders, spread apart in a defined manner, positively abut the inner wall of the nozzle neck.
