High efficiency solid-state light source and methods of use and manufacture

A high-intensity light source is formed by a micro array of a semiconductor light source such as a LEDs, laser diodes, or VCSEL placed densely on a liquid or gas cooled thermally conductive substrate. The semiconductor devices are typically attached by a joining process to electrically conductive patterns on the substrate, and driven by a microprocessor controlled power supply. An optic element is placed over the micro array to achieve improved directionality, intensity, and / or spectral purity of the output beam. The light module may be used for such processes as, for example, fluorescence, inspection and measurement, photopolymerzation, ionization, sterilization, debris removal, and other photochemical processes.

System and method for improved registration performance

An apparatus and method for advancing a receiver into registered relationship with a moving image-bearing member. A motor is provided that is responsive to motor drive pulses. A drive member engages the receiver, and a drive coupling connects the drive member and the motor. An encoder generates encoder pulses that correspond with movement of the image-bearing member. A pulse generator generates motor drive pulses in response to the encoder pulses to accelerate the receiver to a speed approximately equal to the speed of the image-bearing member speed. A timer determines an amount of delay time between detection of the receiver by an in-track sensor and the beginning of a subsequent movement of the motor. A delay mechanism delays the acceleration of the receiver to the image-bearing member speed by the amount of delay time.

Non-contact transfer printing

A transfer printing process that exploits the mismatch in mechanical or thermo-mechanical response at the interface of a printable micro- or nano-device and a transfer stamp to drive the release of the device from the stamp and its non-contact transfer to a receiving substrate are provided. The resulting facile, pick-and-place process is demonstrated with the assembling of 3-D microdevices and the printing of GAN light-emitting diodes onto silicon and glass substrates. High speed photography is used to provide experimental evidence of thermo-mechanically driven release.

Smooth finish UV ink system and method

A printing method includes steps of applying an ink-receptive coating to a substrate; printing an actinic radiation-curable ink jet ink over the coating; and curing the printed ink jet ink. An article printed by the method has a ink-receptive coating layer with a cured print. An apparatus for carrying out the method includes a coating station at which the ink-receptive coating is applied to a substrate, an ink jet printhead at which the energy-curable ink jet ink is applied, and a source of actinic radiation for curing the applied ink. The ink may be applied in sufficient amount to achieve a color density comparable to that obtained using other printing processes such as flexographic or gravure printing processes. The ink-receptive coating layer may be of a thickness sufficient to provide improve surface smoothness and / or reduced drop spread relative to an uncoated substrate.

Extended functionality for an inverse inference engine based web search

An extension of an inverse inference search engine is disclosed which provides cross language document retrieval, in which the information matrix used as input to the inverse inference engine is organized into rows of blocks corresponding to languages within a predetermined set of natural languages. The information matrix is further organized into two column-wise partitions. The first partition consists of blocks of entries representing fully translated documents, while the second partition is a matrix of blocks of entries representing documents for which translations are not available in all of the predetermined languages. Further in the second partition, entries in blocks outside the main diagonal of blocks are zero. Another disclosed extension to the inverse inference retrieval document retrieval system supports automatic, knowledge based training. This approach applies the idea of using a training set to the problem of searching databases where information that is diluted or not reliable enough to allow the creation of robust semantic links. To address this situation, the disclosed system loads the left-hand partition of the input matrix for the inverse inference engine with information from reliable sources.

Web-fed rotary printing press for rapid change in production

The invention relates to a web-fed rotary printing press having a plurality of double printing units in which each of the printing units of the double printing units work together in the blanket-blanket method and each has its own drive. Transfer cylinders of each printing unit are driven independently. To permit a rapid change in production, both upon recto and verso printing, the transfer cylinders of the disconnectable double printing units are separable by eccentric bushings or swingable levers such that a web which passes through the printing press is conducted between them without being printed.
