  • Patent number: 11904609
    Abstract: An inkjet head includes a pressure chamber in which ink is stored, a nozzle plate including a nozzle which connects with the pressure chamber, an actuator configured to change a volume of the pressure chamber, and a drive circuit. The drive circuit, before a printing is performed, outputs, to the actuator for a first time period, a first signal for changing the volume of the pressure chamber without ejecting ink from the nozzle. A second signal for changing the volume of the pressure chamber is then output to the actuator for a second time period such that ink is ejected from the nozzle. A third signal for changing the volume of the pressure chamber to the extent that the ink is not ejected from the nozzle is then output to the actuator for a third time period.

  • Patent number: 11893328
    Abstract: This application relates to apparatus and methods for generating, and executing, surrogate models. In some examples, a computing device generates and evaluates correlations between input and output variables for a system to identify highly correlated input and output parameters. In addition, weights for one or more of the parameters may be determined. The computing device identifies a mathematical relationship between input and output variables to generate a physics model. The computing device may also identify other features not captured by the physical relationship that are highly correlated to each other, and generates a feature model that is based on the highly correlated features. The computing device may optimize the feature model based on a culling process that reduces the computational resources required to execute the feature model. The physics model is then combined with the feature model to generate a system output model that can simulate the system.

  • Patent number: 11862300
    Abstract: Chemical formulations for chemical products can be represented by digital formulation graphs for use in machine learning models. The digital formulation graphs can be input to graph-based algorithms such as graph neural networks to produce a feature vector, which is a denser description of the chemical product than the digital formulation graph. The feature vector can be input to a supervised machine learning model to predict one or more attribute values of the chemical product that would be produced by the formulation without actually having to go through the production process. The feature vector can be input to an unsupervised machine learning model trained to compare chemical products based on feature vectors of the chemical products. The unsupervised machine learning model can recommend a substitute chemical product based on the comparison.

  • Patent number: 11850845
    Abstract: A process is disclosed for creating a print profile to control the operation of a direct-to-shape printing system for applying images on the exterior of an axially symmetrical media object that has a contoured, varying exterior surface, such as occurs on curved wine bottles and sports equipment like bats. The process takes a media recipe holding media geometry information and an image intended to be printed and processes that information to control a motion control subsystem and a print engine subsystem. The geometry information is manipulated to generate a CAM table suitable for the motion control subsystem, and the image file is processed to create a raster image file suitable for ink head expression. Various setup values are included in the process to prepare the direct-to-shape printing system for use of the media recipe.
