  • Patent number: 11816809
    Abstract: Embodiments described herein provide a system for facilitating dynamic assistance to a user in an augmented reality (AR) environment of an AR device. During operation, the system detects a first element of an object using an object detector, wherein the object is associated with a task and the first element is associated with a step of the task. The system then determines an orientation and an alignment of the first element in the physical world of the user, and an overlay for the first element. The overlay can distinctly highlight one or more regions of the first element and indicate how the first element fits in the object. The system then applies the overlay to the one or more regions of the first element at the determined orientation in the AR environment.

  • Publication number: 20230357566
    Abstract: Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a polymer matrix comprising a first polymer material and a second polymer material that are immiscible with each other, and a plurality of piezoelectric particles located in at least a portion of the polymer matrix. The piezoelectric particles may remain substantially non-agglomerated when combined with the polymer matrix. The compositions may define an extrudable material that is a composite having a form factor such as a composite filament, a composite pellet, a composite powder, or a composite paste. Additive manufacturing processes using the compositions may comprise forming a printed part by depositing the compositions layer-by-layer.

  • Patent number: 11809932
    Abstract: Access is provided to a variable data printing app and a code detection app on a computer server. The variable data printing app is adapted to add machine-readable code to printable items and create a decoder app capable of decoding the machine-readable code. The code detection app is adapted to receive user identification information and transmit the user identification information to designer devices. The printable items are printed as printed products. The designer devices validate a user device based on the validity of the user identification information. In response, the variable data printing app is adapted to transmit the decoder app to validated user devices. The code detection app, operating on the user device, is adapted to decode the machine-readable code in user-acquired images into an optional secure link with the designer devices.

  • Publication number: 20230351103
    Abstract: The disclosure discloses methods and systems for automatically validating content of filled-out application forms against one or more corresponding verification documents. The filled-out application form including pre-defined fields and filled-out content, is received at an automatic feeder. Then, one or more corresponding verification documents are received at pre-defined markings on a platen. The verification documents include pre-defined fields and pre-verified content. Thereafter, the filled-out application form and the verification documents are scanned. The scanned filled-out application form and the scanned verification documents are analyzed to extract the filled-out content from the scanned filled-out application form and the pre-verified content from the scanned verification documents. Post extraction, the filled-out content is matched with the pre-verified content and accordingly errors are highlighted in the scanned filled-out application form.

  • Patent number: 11801693
    Abstract: A printing system comprises an ink deposition assembly, a media transport device, and an airflow control system. The ink deposition assembly comprises a printhead to eject ink through a carrier plate opening in a carrier plate. The media transport device holds a print medium against a movable support surface by vacuum suction and transports the print media through a deposition region. The airflow control system comprises a baffle that is movable between an upstream-blocking configuration and a downstream-blocking configuration, and an actuator configured to move the baffle. In the upstream-blocking configuration the baffle blocks airflow through an upstream side of the printhead opening while allowing airflow through a downstream side of the printhead opening. In the downstream-blocking configuration the baffle blocks airflow through the downstream side of the printhead opening while allowing airflow through the upstream side of the printhead opening.
