Latest Patents

Yang's latest patents include a "System and method for predicting inoperative inkjets within printheads in an inkjet printer." This method indicates a need for remedial printhead operation by predicting the number of inoperative inkjets and their locations within at least one printhead at a predetermined time. The prediction utilizes Markov chain Monte Carlo models that correspond to various ranges of area coverage density for inkjet areas of a printhead. Another notable patent is the "System and method for diagnosing inoperative inkjet patterns within printheads in an inkjet printer." This method identifies problems with an inkjet printer by comparing an index for a printhead map that identifies inoperative inkjets with indexes for clusters of extracted feature descriptors stored in a database. The dictionary for this database is developed using unsupervised cluster analysis of datasets comprised of printhead maps.
