Abstract: Focusing optics can include optical elements disposed and bonded in a linear arrangement (linear array) in at least two rows. A transparent bonding agent can secure alignment of the at least two rows of the optical elements. Scattering elements can also be disposed in the transparent polymer to cause light diffusion. Diffused or un-diffused light from a semiconductor laser array can then be caused to pass through the optical element and illuminate a target substrate such as an imaging member in a printing system.

Abstract: A method for forming an image by a print device includes: identifying a first pixel in halftone image data, the halftone image data representing an image to be formed, the first pixel corresponding to a malfunctioning inkjet of a plurality of inkjets. The method further includes identifying a neighboring pixel within a region of the image around the first pixel, the neighboring pixel corresponding to a functioning inkjet. The method further includes generating a modified halftone value for the neighboring pixel by: identifying a missing color associated with the malfunctioning inkjet, identifying a replacement color to compensate the missing color (the replacement color being a different color than the missing color), and modifying a halftone value for the neighboring pixel based on the replacement color. The method further includes causing the functioning inkjet to eject an ink drop based on the modified halftone value for the neighboring pixel.

The ejected uppermost photopolymer layer is partially cured and a portion of mesh sheet is positioned on the partially cured layer before the at least one eject continues to eject photopolymer material onto the uppermost layer. The portion of the mesh sheet reinforces the layers of photopolymer material and adds strength and durability to the overall part being formed with the photopolymer material.

Abstract: A micro-assembly system includes a reservoir that stores a supply of chiplets suspended in a suspension fluid. Each of the chiplets has a bottom major surface that defines a right side down orientation. The system includes a delivery surface or belt that delivers the chiplets from the reservoir to an assembly surface. The system includes a micro assembler that may arrange the first subset of the chiplets in a pattern on the assembly surface. The micro assembler moves the first subset of chiplets towards a subsequent assembly stage. The micro assembler has an array of field generators fixed relative to the assembly surface that move the first subset of the chiplets along the assembly surface in response to signals applied to each of the field generators.

Abstract: User identification information is received through a user interface device. A processor device supplies the user identification information through an input/output device to an external computerized device to receive, in response, external authorization to use features of an apparatus. The user interface device outputs a menu having options to create a local account based on the external authorization and, in response, receives instructions to create a local account using the processor device. The local account is created based on the instructions being received using the processor device. The local account is stored in a memory device. After creation of the local account, the processor device generates local authorization to use the features of the apparatus based on the user identification information matching information in the local account stored in the memory device, without contacting the external computerized device for the external authorization.

Abstract: An app is supplied to user devices. The app provides shared device cards to digital wallets of the user devices. The shared device cards supply entity-specific authentication configuration settings to a shared document processing device. The shared document processing device receives user credentials and uses the entity-specific authentication configuration settings to supply (through a computerized network) the user credentials to entity-specific authentication servers specified in the entity-specific authentication configuration settings. In response, the shared document processing device receives approval/denial for a user to access the shared document processing device from the entity-specific authentication servers. Different shared device cards have different entity-specific authentication configuration settings that correspond to only one of the entity-specific authentication servers, limiting each of the shared device cards to use with a single authentication server.

Abstract: An inkjet printer configures the printheads in a printhead module in an orientation that attenuates a temperature differential between the ink drops ejected by adjacent printheads at a stitch area between the adjacent printheads. The reduced temperature differential helps ensure that the contrasts between the two inks ejected by the adjacent printheads is sufficiently similar that image quality is not adversely impacted.

Abstract: The present disclosure is directed to systems and methods of coordinating threat detection and mitigation among a fleet of trusted devices. As described herein, cybersecurity is a growing concern of many individuals and organizations, especially for those that use multiple electronic devices. In expansive computing environments such as these, security information and event management (SIEM) solutions have been developed. However, providing a holistic solution to a distributed environment remains challenging. According, the systems and methods described utilize an SIEM solution in conjunction with a threat response profile hosted locally on a trusted device within a fleet of trusted devices to provide a coordinated threat response that can be narrowly and/or broadly applied to one or more devices of the fleet of trusted devices.
