  • Extracting gradient features from neural networks
    Patent number: 9792492
    Abstract: A method for extracting a representation from an image includes inputting an image to a pre-trained neural network. The gradient of a loss function is computed with respect to parameters of the neural network, for the image. A gradient representation is extracted for the image based on the computed gradients, which can be used, for example, for classification or retrieval.

  • Method and apparatus for mitigating particulate settling in an ink handling system
    Patent number: 9782973
    Abstract: Printer structures include a controller, a marking engine operatively (meaning directly or indirectly) connected to the controller, and a container connected to the marking engine. The marking engine applies marking material to print media, and the container stores that marking material. The container can include a flexible bladder storing the marking material, and an actuator structure operatively connected to the controller. The actuator structure contacts the flexible bladder and periodically moves portions of the bladder to periodically mix the marking material as controlled by the controller (based on the marking engine being idle for a previously established amount of time). Alternatively, the actuator structure contacts the container can periodically rotate the container to periodically mix the marking material as controlled by the controller.

  • Method for making hydrophobic barriers requiring UV-light treatment
    Patent number: 9782771
    Abstract: Provided is a method of patterning a substrate. The method includes depositing, in a first predetermined pattern, hydrophobic material on a first surface of a hydrophilic substrate. The method includes permeating the hydrophobic material through a thickness of the substrate. The method includes exposing the hydrophobic material to UV-light and sufficiently solidifying the permeated hydrophobic material. The sufficiently solidified hydrophobic material forms a liquid-impervious barrier that separates the substrate into at least one discrete region.

  • Hidden Markov model generation of multi-plane random screens
    Patent number: 9787871
    Abstract: Methods and systems for the in-situ creation of a halftone noise screen layer by layer. Each layer produced is a white noise uniform distributed screen, statistically similar to one generated by a uniform noise function. The generation of each layer, however, is driven by a screen state which is an error based metric on the mean screen threshold. The set of screens produced are not independent of each other; adjacent layers are negatively correlated, while non-adjacent layers are completely uncorrelated. The result of this screen creation is that for any color the variation of coverage across the viewed surface is smaller than the variation produced by randomly generated screen planes. The algorithm is computationally inexpensive and eliminates the need to store multiple screens in memory.

  • Automated form fill-in via form retrieval
    Patent number: 9785627
    Abstract: A method of creating an electronic file corresponding to a printed artifact may include receiving an image file of a document page. The method may include analyzing the image file to detect a potential form identifier on the document page and automatically (without human intervention) performing a search to identify an actual form that corresponds to the potential form identifier. The method may further include validating that the image file is of a document page that corresponds to the actual form, locating a probable fill-in field on the document page and mapping the probable fill-in field to an actual fill-in field of the actual form.

  • System and method for removing three-dimensional printed parts from a platen using inductive heating and gravity
    Patent number: 9782964
    Abstract: A method of manufacturing a three-dimensional object facilitates removal of the three-dimensional object from the platen on which the object was formed. The method includes rotating the platen from a horizontally level position to a position at an angle to the level position to enable gravity to urge the three-dimensional object away from the platen and inductively heating the platen to melt support material at the boundary of the object and the platen to release the three-dimensional object from the platen.

  • USER TONE REPRODUCTION CURVE INK LIMIT WARNING
    Publication number: 20170286816
    Abstract: If elements (curves) of a tone reproduction curve increase application of marking material, the magnitudes of the elements of the tone reproduction curve are summed. If the summed magnitudes of the elements of the tone reproduction curve exceed marking material limits, a warning message is output.

  • METHOD AND SYSTEM FOR IDENTIFYING USER ISSUES IN FORUM POSTS BASED ON DISCOURSE ANALYSIS
    Publication number: 20170286396
    Abstract: A method for categorizing an issue includes, for each of a plurality of categories of issue, providing at least one discourse pattern for identify text sequences that meet the discourse pattern. At least one of the discourse patterns specifies that an instance of a domain term in a domain term vocabulary be present in the text sequence for the pattern to be met. An issue is received which includes a text sequence. The text sequence is categorized based on which, if any, of the discourse patterns are met by the text sequence of the received issue. Information based on the categorization of the text sequence is output.
