Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a cushion. The cushion has a non-face contacting portion structured to be connected to the frame, a face-contacting portion structured to engage the patient's face, and a central portion that interconnects the non-face contacting portion and the face contacting portion. The frame may be structured to allow a forehead support to assume multiple positions, to compensate for replacement cushions that may have a different profile, shape or size. The cushion is structured to compensate for variations in strap tension, treatment pressure and/or movement of the patient. Headgear may be provided with a strap assembly in which one or more straps is provided with selectively adjustable elasticity or extensibility that may be automatically changed in dependence of treatment pressure and/or treatment type.

Abstract: A comfortable low-leak mask assembly for use with Non-Invasive Positive Pressure Ventilation (NIPPV) is provided to improve patient compliance and/or treatment. The mask system may include headgear having straps that are substantially inextensible and/or micro-adjustable; and/or a mask and/or cushion that includes various structures to allow enhanced/tailored sealing and/or fit at selected locations on the patient's face.

Abstract: A vent assembly for use with a mask assembly includes a first vent, a second vent and a selector to switch the flow of exhaled gas from a patient between the first and second vents.

Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a frame to support one of at least first and second compliant patient interfaces and a forehead support adjustably mounted to the frame. The forehead support is structured and configured to be moved between a first position for use with the first patient interface and a second position relative to the frame for use with a second patient interface, whereby the forehead support maintains a horizontal offset distance with the first and second patient interfaces which is substantially constant.

Abstract: An inkjet printer includes a printhead for printing onto a media substrate, the printhead defining a plurality of nozzles from which ink is expelled; an ink tank provided upstream of the printhead; a sump provided downstream of the printhead for collecting unused ink from the printhead, the sump having a lower portion for holding the unused ink and an upper portion defining a headspace of air above the unused ink; a first fluid conduit extending between the printhead and the sump for communicating the unused ink from the printhead to the sump, the first fluid conduit connecting the sump to a position in the printhead upstream of the plurality of nozzles; and a pump connected to the sump, the pump for drawing air from the headspace of the sump into atmosphere and effecting a negative pressure in the printhead upstream of the nozzles. Communication of ink from the ink tank to the printhead is effected by the negative pressure generated by the drawing of air from the headspace of the sump.

Abstract: An inkjet printer that has a printhead with an array of ink ejection nozzles, an upstream ink line for connecting the printhead to an ink supply, a downstream ink line for connecting the printhead to a sump, a pump in the downstream ink line for drawing fluid out of the printhead, a gas inlet in communication with the printhead, the gas inlet being configured to open to atmosphere during a printhead de-priming operation, and close to atmosphere during a printhead priming operation and, an accumulator positioned in the upstream ink line for generating a positive pressure pulse for priming the printhead.

Abstract: A printhead maintenance system for maintaining a printhead having an ink ejection face is provided. The maintenance system comprises: (a) a foaming system for providing liquid foam on the face, (b) a foam transfer surface for receiving the foam from said face, (c) a transport mechanism for feeding said transfer surface through a transfer zone and away from said printhead, and (d) a valve configurable in first and second positions, the first position for establishing fluid communication between said printhead and an ink supply system and the second position for establishing fluid communication between said printhead and said foaming system. The transfer zone is adjacent to and spaced apart from said ink ejection face.

Abstract: A method of minimizing ink consumption during printhead priming in an inkjet printer. The printhead has a nozzle face defining an array of nozzles for ejecting ink on to a media substrate. The method includes the steps of: providing a porous pad having a contact face dimensioned so that it can encompass all the nozzles in the array; moving the porous pad such that the contact face engages the nozzle face to cover the array of nozzles; forcing ink into the printhead under pressure until ink flows out the nozzles in the array and into the porous pad engaged with the nozzle face; and withdrawing the porous pad such that the contact face disengages the nozzle face.

Abstract: A cushion for a respiratory mask assembly includes a breathing chamber forming portion and a face contacting portion formed in one piece of an elastomeric material, and a gusset portion including one or more folds. The breathing chamber forming portion includes a mask interior breathing chamber and the face contacting portion is structured to engage a patient's face. The gusset portion is structured to provide flexibility to the face contacting portion. The breathing chamber forming portion includes a front side of the mask and the face contacting portion includes a rear side of the mask. The breathing chamber forming portion, when provided to a mask frame, includes an exterior surface exposed at the front side of the mask.

Abstract: A printhead cartridge for an inkjet printer is removably receivable in the printer. The cartridge comprises: a pagewidth printhead, an ink delivery system and a maintenance station. The maintenance station comprises: a chassis reciprocally moveable between a first position and a second position, and a printhead maintenance system mounted on the chassis. The printhead maintenance system is moveable by the chassis between the first position in which the printhead is maintained by the maintenance system and the second position in which the maintenance system is disengaged from the printhead. The chassis comprises an engagement formation for complementary engagement with an engagement arm of an engagement mechanism in the printer. The chassis is moveable by means of the engagement mechanism.
