Patents by Inventor Si Qian

Si Qian has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11893449
    Abstract: Techniques for characterizing an optical system (for example, a printer verifier) are provided. In this regard, the optical system may be characterized for scanning a printed image. The characterization of the optical system includes determining an effective aperture size of the optical system, and correspondingly an effective resolution at which the optical system can be configured to scan a portion of the printed image according to verification requirements.
    Type: Grant
    Filed: November 9, 2021
    Date of Patent: February 6, 2024
    Assignee: Datamax-O'Neil Corporation
    Inventors: H Sprague Ackley, Si Qian, Thomas Axel Jonas Celinder, Sebastien D'Armancourt

  • Patent number: 10867145
    Abstract: A system includes a verifier that is operationally integrated with a printer so as to configure one or more elements of the verifier to have a handshake arrangement with one or more elements of the printer when verifying a print quality of a barcode image during printing of the barcode image by the printer. The handshake arrangement can include various unidirectional and/or bidirectional communication signals that are propagated between the verifier and the printer so as to optimize various operational factors such as paper print speed, barcode image verification speed, and barcode verification result intimation. Barcode result intimation can include features such as providing a paper printout indicative of an unacceptable barcode image quality and/or providing a status message upon a display.
