Abstract: An example apparatus including memory to store a first image of a document and a second image of the document, and a processor coupled to the memory, wherein the processor is to: perform optical character recognition on the first image to generate a first output dataset; perform optical character recognition on the second image to generate a second output dataset; and compute a transformation matrix based on the first output dataset and the second output dataset, the transformation matrix to align the first image with the second image.

Abstract: A three-dimensional object may be generated. A controller may be to control an energy source to apply energy to a layer of build material on a support member or previous layer to cause a portion of the layer to coalesce and solidify to form a slice of the three-dimensional object. A radiation sensor may be to measure absorbance or gloss of the layer. The controller may be to receive, from the radiation sensor, data representing measured absorbance or measured gloss of the layer. The controller may be to control the apparatus to modify a process parameter if the measured absorbance or gloss indicates an incorrect degree of solidification of a part of the layer.

Abstract: Fluid flux correction is disclosed. An example method of fluid flux correction includes displacing a fluid volume in a fluid reservoir with a compliant element. The method also includes absorbing fluid surges caused by variations in fluid flux to reduce distortion of at least one ink nozzle meniscus and maintain consistent fluid ejection.

Abstract: Example pages in which text and graphics have been laid out using a mixed text-and-graphics layout template are received from a user. Hyper parameters of a probabilistic model for the mixed text-and-graphics layout template are optimized, based on the example pages.

Abstract: Disclosed is a system and method for representing user interaction with a web service. The method comprises the steps of: acquiring a representation of the actions of a user performing a task with the web service; analyzing the acquired actions to determine semantics and at least one variable describing the user actions; and representing the semantics and the at least one variable in at least one script file, the at least one script file supporting performance of user interaction with the web service based on the semantics and a value provided for the variable.

Abstract: A method to operate an integrated circuit includes operating a locally active memristive device in a locally reactive region of an operating domain where the device exhibits inductor-like behavior, such as a phase shift where a voltage across the device leads a current through the device.

Abstract: The present disclosure is drawn to compositions and methods for a liquid electrophotographic ink printing. The composition comprises a liquid vehicle; ink particles; and a charge director system, comprising i) a primary charge component, ii) a secondary charge component, and iii) an electrical stability additive; such that the charge director system provides the following ink conductivities: a high field conductivity of about 100 pS/cm to about 500 pS/cm, a low field conductivity of about 20 pS/cm to about 200 pS/cm, a direct charge conductivity less than about 30 pS/cm, and a particle conductivity of at least 100 pS/cm. Additionally, the liquid electrophotographic ink can be formulated for printing from a liquid electrophotographic printer.

Abstract: A color-separation LUT and/or algorithm method and apparatus preferably convert input device-color data to output device-colorants, for many color-presentation types—automatically and for arbitrary colorant-set. In one major aspect of the invention, a device-hue ring is defined along six straight edges of a cubical device-hue space (without segments ending at white and black). Preferably coordinates defined along the six segments parametrize the procedure and equipment, i. e. establish colorant indexing by those coordinates (and preferably device-hue). In a second major aspect, plural color transformations—having respective favorable and adverse characteristics—serve different portions of input color space; their outputs merge to combine favorable properties of the transforms. In a third, cusps of the colorant hue planes populate the output side of the hue ring. In a fourth, a colorant sampling technique (faster by several orders of magnitude than exhaustive sampling) canvasses the output space.

Abstract: A printing device is provided which includes ink-dispensing structure which carries a printhead with a leading edge, and which moves in a printing sweep downstream across a printzone, a fairing structure, and a mounting structure which supports the fairing structure for movement with the printhead downstream from the leading edge of the printhead in a position configured to reduce aerodynamic turbulence associated with the leading edge of the printhead during movement of the printhead downstream across the printzone.
