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.

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.

Abstract: Systems and methods are disclosed for autonomous joint detection-classification of acoustic sources of interest. Localization and tracking from unmanned marine vehicles are also described. Based on receiving acoustic signals originating above or below the surface, a processor can process the acoustic signals to determine the target of interest associated with the acoustic signal. The methods and systems autonomously and jointly detect and classify a target of interest. A target track can be generated corresponding to the locations of the detected target of interest. A classifier can be used representing spectral characteristics of a target of interest.

Abstract: A direct-to-object printer includes a sliding arm that carries a plurality of printheads over a planar member for the printing of objects on the planar member and that rotates the plurality of printheads after the printheads have passed over the planar member. The printer then moves the sliding arm in the opposite direction over the planar member to print a different portion of the objects on the planar member while maintaining the same order of the printheads.

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.

Abstract: A surface treatment module is positioned within a printing system to treat the surface of three-dimensional objects prior to printing of the objects. The surface treatment module includes an actuator operatively connected to an applicator so operation of the actuator presses a portion of a cleaning membrane against the surfaces of the three-dimensional objects to remove material from the object surfaces and retracts the applicator and cleaning membrane from the object surface before the objects pass by an array of printheads in the printing system for printing.

Abstract: A printing system treats the surface of three-dimensional objects to be printed to improve the printing of the articles of manufacture. The system includes a surface treatment module that is positioned to part of the printing process and to treat the object surfaces prior to the surfaces being printed.

Abstract: A direct-to-object printer includes a vaporizer to attenuate the effect of oxygen inhibition on the curing of non-aqueous ultraviolet (UV) marking material ejected onto the surface of an object printed by the printer. The vaporizer includes a heating element to form a vapor from a solution of solvent and particulate and a pressurized air source to direct the vapor toward the object to enable a portion of the vapor to condense on the object. The condensed vapor forms a barrier that attenuates the effect of oxygen inhibition on the curing of non-aqueous UV marking material.
