Patent number: 9551934Abstract: A system comprises an electrophotographic subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electrophotographic subsystem comprises a photoreceptor, a charging subsystem, an exposure subsystem, and a development subsystem. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor to thereby write a latent charge image onto the photoreceptor surface. The image is developed with an image definition material, such as a dampening fluid. The image definition material forms a positive pattern of the image to be printed. The image pattern is then transferred to the reimageable surface. The transferred pattern is then developed by selectively applying an ink over regions of image definition material. The inked image may be transferred to a substrate.Type: GrantFiled: February 19, 2016Date of Patent: January 24, 2017Assignees: Xerox Corporation, Palo Alto Research Center IncorporatedInventors: Janos Veres, David K.

Patent number: 9529307Abstract: A system comprises an electro-wetting subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electro-wetting subsystem comprises a photo-responsive photoreceptor, a charging mechanism, an image definition material reservoir, a charge erase mechanism, and an exposure subsystem, such as a light source and rotating polygon forming a raster output scanner (ROS) disposed for exposure of the photoreceptor through the image definition material reservoir. The imaging member comprises a reimageable surface having certain properties, such as having a low surface energy to promote ink release onto a substrate. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor, which is developed with image definition material. The image definition material pattern is transferred to the reimageable surface. The pattern is developed with ink. The inked image may be transferred to a substrate.Type: GrantFiled: July 12, 2012Date of Patent: December 27, 2016Assignee: Palo Alto Research Center IncorporatedInventors: Janos Veres, David K.

Patent number: 9316993Abstract: A method is disclosed in the context of a system comprises an electrophotographic subsystem, a transfer subsystem, an imaging member, and an inking subsystem. The electrophotographic subsystem comprises a photoreceptor, a charging subsystem, an exposure subsystem, and a development subsystem. In operation, the photoreceptor is charged areawise. An exposure pattern is formed by the exposure subsystem on the surface of the charged photoreceptor to thereby write a latent charge image onto the photoreceptor surface. The image is developed with an image defining material, such as a dampening fluid. The image defining material forms a negative pattern of the image to be printed.

Publication number: 20150376768Abstract: A system and method are provided for implementing a unique scheme by which to execute digital vapor phase patterning on metals, semiconductor substrates and other surfaces using a proposed variable data digital lithographic image forming architecture or technique. For certain substrate printing and manufacturing applications, including some printed electronics applications, the disclosed schemes implement techniques to digitally pattern metal layers with bulk material properties in a manner that is aligned with underlying layers on the fly. The disclosed digital printing process may pattern a release oil on a substrate in support of a metal deposition process. Changeable patterning is implemented with an ability to modify the alignment of the patterns on-the-fly. The release layer on a drum is laser patterned in order that the patterned release layer is transferred to the substrate, or the patterning of the release layer is accomplished directly on the substrate.Type: ApplicationFiled: June 30, 2014Publication date: December 31, 2015Inventors: Janos VERES, Timothy D.

Patent number: 9156194Abstract: A replica 3D structure is fabricated inside a multi-layered mold by patterning each mold layer to define a void/opening that matches a corresponding cross section of the structure's peripheral surface, and filling the patterned opening of each layer with a structural material (i.e., before depositing a subsequent layer of mold material). The mold material (e.g., photoresist or another dissolvable sacrificial material) is blanket deposited (e.g., by slot-die, spray coating) and then patterned using a laser or a printed mask. Each layer of modeling material (e.g., polymer, ceramic or metal, or a combination thereof) is electro-plated or otherwise deposited on the previously formed modeling material layer. High vertical resolution is achieved by utilizing relatively thin mold layers. The mold layer deposition, patterning and modeling material deposition is repeated until the replica 3D structure is entirely formed inside the multi-layered mold, and then the mold is dissolved or otherwise removed.Type: GrantFiled: March 14, 2013Date of Patent: October 13, 2015Assignee: Palo Alto Research Center IncorporatedInventors: Tse Nga Ng, JengPing Lu, Eugene M.

Patent number: 8872224Abstract: A low-cost neutron detector is formed on a substrate includes a sensor formed by an active material layer sandwiched between two electrodes, and a neutron capture layer formed in close proximity to (i.e., over and/or under) the sensor. The sensor active material layer includes a bulk heterojunction or bilayer structure that is formed by depositing particulate solutions incorporating at least one type of high atomic number nanoparticle using low-temperature (i.e., below 400° C.) solution processing techniques. The sensor electrode material and neutron capture material are similarly disposed in associated solutions (e.g., conductive inks) that are also deposited using low-temperature solution processing techniques, whereby the fabrication process can be carried out on low-cost flexible substrate material (e.g., PET) using high efficiency roll-to-roll production techniques.Type: GrantFiled: March 14, 2013Date of Patent: October 28, 2014Assignee: Palo Alto Research Center IncorporatedInventors: Gregory L.
