  • Patent number: 10999465
    Abstract: According to aspects illustrated herein, methods and systems for retaining duplex scanning information in a scanned output file, is disclosed. The method includes receiving a document for scanning, having multiple pages, wherein each page has a first side such as a front side and a second side such as a back side. Then, a check for selection of a duplex scanning feature by a user, is performed. Upon scanning, an image data representing an image of the document is generated. The image data and the duplex scanning feature selected by the user is processed to generate a scanned output file. The duplex scanning information is generated, while generating the scanned output file. The duplex scanning information is retained in the scanned output file, for later retrieval and use. The duplex scanning information helps identify the first side and the second side in the scanned output file.

  • Patent number: 10999449
    Abstract: A method for measuring a blur of a print job and adjusting printer parameters in response to the blur is disclosed. For example, the method may be performed by a multi-function device (MFD) and includes printing an image on a print media, scanning the image, calculating a blur count for each location of the image in a cross-process direction, determining that the blur count for at least one location of the image is above a blur threshold, and adjusting at least one print parameter for a subsequently printed image on the MFD.

  • Patent number: 10999466
    Abstract: A first pattern and the second pattern in an original include relatively lighter markings within a relatively darker background. The first pattern differs from the second pattern by including non-printing patches between the relatively lighter markings. When exposed to ultraviolet light, the underlying print media fluoresces in response to the ultraviolet light at the non-printing patches, revealing hidden security printing features. When a scanned image is printed on a second sheet of print media to produce a copy of the original, the copy maintains distinct markings at locations where the relatively lighter markings and the non-printing patches appear because the spacing interval of the relatively lighter markings and the non-printing patches is at or above the minimum resolution of the scanner. Thus, when the original and the copy are exposed to ultraviolet light, both fluoresce the ultraviolet light where the non-printing patches appear in the original.

  • Publication number: 20210121947
    Abstract: A method for printing a structure, the structure including a plurality of pillars. The method for printing can include ejecting only a first drop of a print material such as a liquid metal sequentially at each of a plurality of pillar locations, then ejecting only a second drop of the print material sequentially onto the first drop at each of the plurality of print locations. Additional drops can be ejected at two or more of the pillar locations to form the plurality of pillars. Ejecting only a first drop at each pillar location allows the first drop to cure (i.e., cool or dry) before ejecting the second drop. The printer continues printing while the drops cure, thus improving processing efficiency and increasing production throughput.

  • Patent number: 10990337
    Abstract: In systems and methods, a print server receives an original print job in an originated format that is associated with a user through a network. The print server identifies potentially used printers that can be utilized to print the original print job based on a current physical location of a mobile wireless device associated with the user. The print server converts the original print job from the originated format into printing formats used by the potentially used printers to generate print-ready print jobs. The print server is adapted to send the print-ready print jobs to the potentially used printers through the network when the print-ready print jobs are created. A selected printer of the potentially used printers receives an instruction to print the original print job and the selected printer prints a received one of the print-ready print jobs when the selected printer receives the instruction to print.

  • Patent number: 10981742
    Abstract: An apparatus for controlling curl in sheets between two transports includes a curved baffle placed between the two transports. A thin layer of high velocity air is applied to the curved baffle. The high velocity air layer, which will have a tendency to follow the curved baffle (Coanda effect), will divert sheets (Bernoulli effect) towards the curved baffle. By positioning the curved baffle between the two transports and by applying a uniform air stream to it, a lower pressure area will be created. This will flatten the trajectory of the sheets and ensure acquisition by the downstream transport.

  • Patent number: 10984355
    Abstract: When monitoring a workspace to determine whether scheduled tasks or chores are completed according to a predetermined schedule, a video monitoring system monitors a region of interest (ROI) to identify employee-generated signals representing completion of a scheduled task. An employee makes a mark or gesture in the ROI monitored by the video monitoring system and the system analyzes pixels in each captured frame of the ROI to identify an employee signal, map the signal to a corresponding scheduled task, update the task as having been completed upon receipt of the employee signal, and alert a manager of the facility as to whether the task has been completed or not.

  • Patent number: 10986249
    Abstract: An image processing device includes a neutral edge detection and enhancement component which, for pixels of an input image, computes an edge strength for the pixel as a function of differences between the input luminance value of the pixel and input luminance values of neighboring pixels, computes a neutral adjustment factor for the pixel as a function of the input luminance value of the pixel, and computes a chroma adjustment factor for the pixel as a function of the input chrominance values of the pixel. An adjusted luminance value for the pixel is computed as a function of the input luminance value, the edge strength, and the neutral adjustment factor. Adjusted chrominance values for the pixel may be computed as a function of the input chrominance value, the edge strength, and the chroma adjustment factor. The system allows detection and enhancement of neutral edges in monochrome and color images.
