  • Patent number: 11914621
    Abstract: An association metric for record attributes associated with cardinalities that are not necessarily the same is used for training and/or applying an entity resolution (ER) model. A pair of records includes (a) a first record indicating a first set of values for a first attribute and (b) a second record indicating a second set of values for a second attribute. Each of the first set of values and each of the second set of values are compared to determine individual association metrics. A first-level reduction operation is applied to subsets of the individual association metrics to determine reduced association metrics. A second-level reduction operation is applied to the reduced association metrics to determine an association metric, for the pair of records, for training and/or applying an ER model.

  • Patent number: 10894411
    Abstract: A cap is positioned to contact a printhead when the printhead is not ejecting liquid ink. The cap and the printhead create a sealed space adjacent printhead nozzles when contacting each other. A flexible blade is positioned to contact the printhead when the printhead is not in contact with the cap. The flexible blade is adapted to fold over to spread a liquid solution on the nozzles in a first direction, and the flexible blade is adapted to remove excess amounts of the liquid solution from the nozzles in a second direction. A humidifier is connected to the cap and adapted to supply a moisture form of the liquid solution to the sealed space. A moisture sensor is connected to the cap. The humidifier is adapted to vary supply of the moisture to the sealed space based on the amount of moisture detected by the moisture sensor.

  • Patent number: 10814635
    Abstract: Devices include one or more inkjet printheads, a reusable jetting sheet that is adjacent to nozzles of the printheads, support structures (e.g., drive rollers) contacting the sheet, and a cleaning station contacting the sheet. The reusable jetting sheet includes an opening, that is at least as large as the sets of nozzles, and a jetting area spaced from the opening. The support structures are adapted to move the reusable jetting sheet relative to the sets of nozzles. The inkjet printheads are adapted to eject ink from at least some of the nozzles, through the opening, to print media when the opening is positioned adjacent to the sets of nozzles, to print on print media. The inkjet printhead is further adapted to eject ink from at least some of the nozzles to the jetting area when the jetting area is positioned adjacent to the sets of nozzles to perform maintenance jetting.

  • Patent number: 10814653
    Abstract: A roller for a transport belt of a vacuum transport assembly includes an elongate cylindrical body adapted for a rotatably fixed connection to a vacuum transport assembly. An outer surface of the roller defines a hollow inner channel, which extends along an axial region of the body. The outer surface is a running surface for a transport belt. An inlet at one end of the hollow inner channel receives air from an air source. Perforations are formed in the outer surface for allowing air pressure to be discharged from the hollow inner channel toward the transport belt. The air diffuses through the transport belt to detack a sheet from the transport belt.

  • Patent number: 10751935
    Abstract: The automation of the assembly of a stack of substrates in the process of forming an object includes a blanking die having a push through plate to drive the blanked sheets onto a set of locating pins, thereby creating a very accurate stack. An image forming device may print and develop images onto a web that is subsequently die cut and stacked onto a curing platen. The die cutter cuts individual sheets out of the web and cuts or pre-cuts alignment holes into each sheet that would be accepted by the curing platen having locating pins corresponding to the alignment holes in the sheet. The die cutting operation includes a tamping device that would accurately transfer the sheets from the die to the curing platen. This stack may then be removed and/or processed to form a 3D object.
