  • Patent number: 10296846
    Abstract: A domain-adapted classification system and method are disclosed. The method includes mapping an input set of representations to generate an output set of representations, using a learned transformation. The input set of representations includes a set of target samples from a target domain. The input set also includes, for each of a plurality of source domains, a class representation for each of a plurality of classes. The class representations are representative of a respective set of source samples from the respective source domain labeled with a respective class. The output set of representations includes an adapted representation of each of the target samples and an adapted class representation for each of the classes for each of the source domains. A class label is predicted for at least one of the target samples based on the output set of representations and information based on the predicted class label is output.

  • Patent number: 10293547
    Abstract: A three-dimensional (3-D) printer includes build and support material development stations positioned to transfer layers of build and support materials to an intermediate transfer surface. The intermediate transfer surface transfers a layer of the build and support materials to a platen each time the platen contacts the intermediate transfer surface. A sensor detects the thickness of the layer on the platen, and a mechanical planer is positioned to contact and level the layer on the platen as the platen moves past the mechanical planer. Additionally, a feedback loop is electrically connected to the sensor and the mechanical planer. The mechanical planer adjusts the amount of the build material and the support material removed from the layer based on the thickness of the layer on the platen, as determined by the sensor.

  • Patent number: 10291816
    Abstract: A method of operating a three-dimensional object printer includes generation of a printed predetermined test pattern on a substrate in the printer with a plurality of ejectors in a printhead. An image sensor generates image data of the printed test pattern and a controller identifies a z-axis distance between the printhead and the substrate that receives the test pattern with reference to an identified dispersion between cross-process direction distances separating printed marks in the test pattern.

  • Patent number: 10289909
    Abstract: A method and apparatus for classifying an image. In one example, the method may include receiving one or more images associated with a source domain and one or more images associated with a target domain, identifying one or more source domain features based on the one or more images associated with the source domain, identifying one or more target domain features based on the one or more images associated with the target domain, training a conditional maximum mean discrepancy (CMMD) engine based on a difference between the one or more source domain features and the one or more target domain features, applying the CMMD engine to the one or more images associated with the target domain to generate one or more labels for each unlabeled target image of the one or more images associated with the target domain and classifying each one of the one or more images in the target domain using the one or more labels.

  • Patent number: 10291407
    Abstract: Systems and methods are described that facilitate capturing promotional information details such as the number of promotional material items printed for a given vendor supported by a marketing agency, item size, placement details, price, and authentication information to prove that a print log or summary is genuine. The authentication information can include a timestamp, printer identity, job identity and run-length. This information is summarized in a message digest and is signed by the printing system using digital signatures, which are then verified by the marketing agency through a public key counterpart of a private key used to generate the signatures.

  • Patent number: 10279585
    Abstract: A printer is configured with an optical sensor that enables dashes in a test pattern formed with clear drops on a mirror-like surface to be detected and their positions identified. The optical sensor includes a louver positioned adjacent to a light source to limit and collimate an amount of light emitted by the light source onto each portion of the test pattern. The limiting of the light facilitates the processing of the image data generated by a plurality of photodevices that receive the specular light reflections from the mirror-like substrate and the test pattern to identify the positions of the dashes. These identified positions are compared to expected positions to identify misalignment distances that can be used to adjust ejector head alignment and timing of the firing signals to the ejector head that ejects clear drops.

  • Patent number: 10279456
    Abstract: A universal object holding mechanism for holding three-dimensional objects for printing thereon uses an array of suction cups reciprocally connected to a vacuum box to acquire objects from a staging platen while in a horizontal position and then pivot into a vertical position for movement of the objects past print heads. A plenum connected to the vacuum box is valve controlled to allow a low flow rate to the vacuum box to acquire objects and then a high flow rate pulse to close off all un-sealed suction cups with ball valves.

  • Patent number: 10284740
    Abstract: An original has a first pattern on and a second pattern, and the first pattern and the second pattern include relatively lighter markings within a relatively darker background. The relatively lighter markings appear at a first spacing interval in the first pattern, and at a larger second spacing interval in the second pattern. The first pattern and the second pattern cover and equally block a region of the original from reflecting ultraviolet light. A scanner is only capable of detecting patterns of markings having a spacing interval larger than the first spacing interval, which causes a copy of the original to not include the relatively lighter markings appearing at the first spacing interval. Thus, the copy lacks markings at locations corresponding to where the relatively lighter markings appear at the first spacing interval in the original. The copy reflects the ultraviolet light more where the copy lacks markings.

  • Patent number: 10279577
    Abstract: A 3-D printer includes development stations that electrostatically transfer first and second materials to an intermediate transfer surface. The development stations can each include a photoreceptor supplying the materials to the intermediate transfer surface, and a boosted developer roll supplying the materials to the photoreceptor. The boosted developer roll comprises an outer roll rotating in a first rotational direction to move with movement of the photoreceptor, and a magnetic roll within the outer roll rotating in a second rotational direction opposite the first rotational direction. The magnetic roll comprises alternating permanent magnets. The intermediate transfer surface transfers a layer of the materials to a platen each time the platen contacts the intermediate transfer surface to successively form a freestanding stack of layers on the platen. A bonding station is positioned to apply light and/or heat to the freestanding stack to bond the layers to one another.

  • Publication number: 20190126203
    Abstract: A system and method are described for regulating water concentration in a dielectric fluid. The system can comprise electrodes capable of applying an electric field across the dielectric fluid, thereby causing charge carriers and water included in the charge carriers to move toward a respective electrode. The system further includes a trap positioned near the electrodes and comprising a water absorbing material capable of trapping water, thereby reducing the concentration of water in the dielectric fluid. It is also possible to measure properties of the dielectric fluid and use such measurements to control the water-trapping process.
