Abstract: The present invention relates to active respiratory protective face shield systems. More specifically, the present invention is directed to face shield systems comprising a substantially transparent lens having an upper visual chamber and a lower breathing chamber. The protective face shield systems have a generally open design so to not substantially contact the user's face. The lens configured to cover at least the user's nose and mouth. An input filter system module provides a positive pressure environment to a breathing chamber by the delivery of filtered air. The positive pressure is of sufficient magnitude so to produce an air barrier for substantially preventing environmental contamination, e.g., particulate matter, microorganisms, and the like, from entering the breathing chamber. Alternate embodiments further include an output filter system module for the evacuation and substantial filtration of the user's exhalation air to surrounding environment.

Abstract: A planar continuous elongated ring configured to engage a filtration textile to a nose-mouth perimeter of a user, said continuous elongated ring including an upper curvilinear portion adapted to engage said filtration textile disposed about a nasal periphery of the user; said upper curvilinear portion including a pair of attachment features adapted to fastenly receive an upper support strap configured to engage the user's head, and a lower curvilinear portion adapted to engage said filtration textile disposed about a mouth periphery of the user, the lower curvilinear portion including a pair of attachment features adapted to fastenly receive a lower support strap configured to engage the user's head.

Abstract: The present disclosure delineates both active as well as passive respiratory filtration systems. The respiratory filtration systems are configured to be worn by a user, providing the user protection from the ambient environment, possibly containing microorganisms, pathogens, particulate matter, and the like. Some embodiments are also designed to protect observers, by filtering user exhalation air released into the environment. Nontransparent members of the system are configured to be located over impassive features of the user's face, such as the cheeks or chin areas. The disclosed respiratory filtration system(s) includes one or more hygienic materials. The hygienic materials are carefully selected and disposed at predetermined locations within the respiratory filtration system, so to optimize user to the observer(s) communications. Optimized communications include the transmission of distortion-free speech and/or unobstructed view of the user's oronasal area—via an expression window(s).

Abstract: An active respiratory filtration system that provides a continuous flow of filtered air to a face mask, covering the nose and mouth of the user. The forced air is directed into the inner volume of the face mask, creating a positive pressure which yields several advantages, including: reducing user inhalation, reducing heat built-up within the face mask's inner volume, help overcome face mask perimeter seal breach issues. Some embodiments include the use of pliable mask filters, enabling the filtration of exhalation air from the user to the environment, thereby protecting others. Other embodiments include at least one check valve integrated into the face mask, thereby reducing the user exhalation effort. The system is configured to be compact, light-weight and portable.

Abstract: A jetting-module cleaning system for cleaning the nozzle plate of a jetting module includes a non-rotating shaft and a rotating wiper mechanism. The non-rotating shaft includes one or more outlet openings extending from its hollow core to its outer surface. The rotating wiper mechanism includes a rotating sleeve having one or more openings extending from its hollow core to its outer surface, and one or more wiper blades. The rotating wiper mechanism rotates around the non-rotating shaft. A pressurized fluid source supplies pressurized cleaning fluid to the hollow core of the non-rotating shaft. An actuator rotates the rotating wiper mechanism around its axis. Cleaning fluid is sprayed onto the nozzle plate through the one or more outlet openings in the non-rotating shaft when the openings in the rotating sleeve are aligned with the outlet openings in the non-rotating shaft.

Abstract: An inkjet printing system includes a fluid coupling assembly for supplying fluid to a jetting module. The jetting module includes an electrical connector adapted to connect with a corresponding electrical cable, and a jetting module attachment face with a jetting module fluid port. The fluid coupling assembly includes a coupling assembly attachment face with a coupling assembly fluid port in a position corresponding to the jetting module fluid port. A latch mechanism on the fluid coupling assembly includes a latch handle and a latch fastener adapted to engage with a latch keeper on the jetting module. When the latch handle is in a first disengaged position the latch mechanism blocks the electrical connector, and when the latch handle is in a second engaged position the latch fastener engages the latch keeper to secure the fluid coupling assembly to the jetting module.

Abstract: An inkjet printhead assembly includes a repositionable shutter mechanism adapted to block a slot through which drops of ink ejected from the array of nozzles pass before they impinge on the print medium. The shutter mechanism includes a repositionable shutter blade extending in a cross-track direction having a pivot axis passing through first and second tabs affixed to its ends. A first slide mechanism component is pivotably attached to an end of an actuator rod, and a second slide mechanism component is rigidly attached to the repositionable shutter blade. An actuator is configured to translate the actuator rod, thereby pivoting the repositionable shutter blade about the pivot axis between a first pivot position where the shutter blade blocks the slot and a second pivot position where the shutter blade is moved away from the slot so that drops of ink can pass through the slot.

Abstract: A method for printing image data with a printing system having a staggered array of overlapping printheads. Adjacent printheads overlap in the cross-track direction defining an overlap region such that image pixels corresponding to the overlap region can be printed with either first or second printheads. The method includes defining an initial row interval N and an initial position of a transition boundary within the overlap region. N rows of image pixels are then printed wherein image pixels on one side of the transition boundary are printed using the first printhead and image pixels on the other side of the transition boundary are printed using the second printhead. A random process is used to iteratively determine updated row intervals, where the position of the transition boundary is shifted by an increment amount of between one pixel and three pixels for each row interval.

Abstract: A modular inkjet printhead assembly including a plurality of printhead modules mounted on alternating sides of a central rail assembly. The rail assembly includes a beam and a rod attached to a side of the beam. The printhead modules include a jetting module having an array of nozzles, a first alignment tab having a first alignment datum and a second alignment datum, a second alignment tab having a third alignment datum and a fourth alignment datum, a rotational alignment feature including a fifth alignment datum, and a cross-track alignment feature including a sixth alignment datum. Portions of the alignment tabs of the jetting module are adapted to fit within corresponding notches in the beam. A jetting module clamping mechanism and a jetting module cross-track force mechanism apply forces to the jetting module that causes each alignment datum to engage with corresponding alignment features on the rail assembly.
