20130176578 | Mask Generation Mechanism - A method is disclosed. The method includes generating a seed pattern which ensures one dot per column, computing an auto correlation function and performing pixel error processing. Pixel error processing includes performing multiple operations during each iteration to create visually pleasing halftone mask patterns which follow a one dot per column constraint. | 07-11-2013 |
20130176599 | Halftone Screen Generation Mechanism - A method is disclosed. The method includes generating a Continuous Tone Image (CTI) with all pixel values same as the first gray level and an initial Half Tone Image (HTI) with all pixel values equal to minimum absorptance level, computing a change in pixel error by toggling with all the possible output states and swapping with all neighbor pixels only if the stacking constraint is satisfied, updating the HTI with the maximum error decrease operation and continue to next pixel location till the end criteria is met. Once the end criteria is met, the updated HTI is saved as a final halftone screen for that gray level and copied as the initial HTI for the next gray level along with CTI pixel values updated to the next gray level till the final gray value is reached. | 07-11-2013 |
20130176600 | Halftone Calibration Mechanism Employing an Ink Model - A printing system is disclosed. The printing system includes a halftone calibration system that receives one or more un-calibrated halftones, generates one or more calibrated halftones using an ink model from the one or more un-calibrated halftones, analyzes a printed calibration screen of the one or more calibrated halftones, and performs a halftone calibration. | 07-11-2013 |
20130257969 | Print Head Alignment Mechanism - A printing system is disclosed. The printing system includes a print engine including two or more print heads to generate an alignment chart and an alignment system. The alignment system receives the alignment chart and computes a magnitude of misalignment between the print heads. | 10-03-2013 |
20130265611 | Hybrid Halftone Generation Mechanism - A method is disclosed. The method includes generating a Continuous Tone Image (CTI) with all pixel values same as a first gray level, generating an initial Half Tone Image (HTI) with all pixel values equal to minimum absorptance level and computing a change in pixel error for a first pixel. The change in pixel error is computed by identifying a first pixel indicated in a valid pixel map, toggling the first pixel with all the possible output states and swapping the first pixel with all neighbor pixels only if the stacking constraint is satisfied, updating the HTI with the maximum error decrease operation and continue to next pixel location till the end criteria is met. | 10-10-2013 |
20130265612 | Hybrid Halftone Generation Mechanism - A method is disclosed. The method includes generating a Continuous Tone Image (CTI) with all pixel values same as a first gray level, generating an initial Half Tone Image (HTI) with all pixel values equal to minimum absorptance level and computing a change in pixel error for a first pixel. The change in pixel error is computed by identifying a first pixel indicated in a valid pixel map, toggling the first pixel with all the possible output states and swapping the first pixel with all neighbor pixels only if the stacking constraint is satisfied, updating the HTI with the maximum error decrease operation and continue to next pixel location till the end criteria is met. | 10-10-2013 |
20140233069 | Method and System for Halftoning Using Energy Minimization - A method is disclosed. The method includes generating a set of points via energy minimization to implement halftone seed pattern. | 08-21-2014 |
20140240803 | Toner Estimation Mechanism - A method is disclosed. The method includes estimating a quantity of toner to be used to print a job at a printer by calculating a buildup of toner at edges of data on each page of the print job. | 08-28-2014 |
20140253976 | Hybrid Halftone Generation Mechanism - A method is disclosed. The method includes generating a halftone screen using a Direct Multi-bit Search Screen Algorithm (DMSSA) to optimize a halftone pattern at each gray level. | 09-11-2014 |
20150025693 | SYSTEM AND METHOD OF TEMPERATURE CONTROL - A structure and method for temperature control includes determining a schedule for a climate control device needed for an inside temperature to reach a desired temperature, determining a perceptual temperature factor based on at least the schedule and the inside temperature, adjusting the desired temperature based on the perceptual temperature factor, and after the adjusting the desired temperature, repeating the determining the schedule. | 01-22-2015 |
20150055185 | Halftone Mechanism - A method is disclosed. The method includes applying a human visual system (HVS) model to a Continuous Tone Image (CTI) and a initial Half Tone Image (HTI) to generate a perceived CTI and a perceived HTI and computing a change in pixel error for a first pixel by toggling the first pixel with all the possible output states and swapping the first pixel with all neighbor pixels. | 02-26-2015 |
