  • Patent number: 11504963
    Abstract: A compliant surface is created with micron scale pits or dimples above an electrically biased conductive layer. The dimples are filled partially with fountain solution and brought adjacent a surface bearing a charge image. The field lines between pixel charge and backplane conductive layer are guided by the dielectric variations defined by the dimple walls and the fountain solution. Dielectrophoretic forces cause the fountain solution within the dimples to flow up to the charge image and wet the surface. A desired volume is controlled by varying parameters such as nip pressure. The developed latent image is then brought into contact with a transfer member blanket and split, thus creating on the blanket a fountain solution latent image ready for inking.

  • Patent number: 11508169
    Abstract: Embodiments described herein provide a system for generating synthetic images with localized editing. During operation, the system obtains a source image and a target image for image synthesis and selects a semantic element from the source image. The semantic element indicates a semantically meaningful part of an object depicted in the source image. The system then determines the style information associated with the source and target images. Subsequently, the system generates a synthetic image by transferring the style of the semantic element from the source image to the target image based on the feature representations. In this way, the system can facilitate localized editing of the target image.

  • Patent number: 11486919
    Abstract: An approach to detecting partial discharge events involves retrofitting an electrical system to include a capacitive sensor configured to capacitively sense partial discharge events of a component of the electrical system. The capacitive sensor has a first electrical conductor that forms a first terminal of the capacitive sensor, a second electrical conductor that forms a second terminal of the capacitive sensor, and a dielectric that separates the first electrical conductor and the second electrical conductor. The capacitive sensor generates an electrical sensor signal at an output of the capacitive sensor in response to the partial discharge event. The electrical sensor signal is converted to an optical signal and the optical signal is processed to detect an occurrence of the partial discharge event.

  • Patent number: 11479850
    Abstract: 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.
