Abstract: An example device includes a defrothing portion to separate froth into a coalesced fluid and air, an air vent to vent the air from the defrothing portion, and a membrane on an outer surface of the defrothing portion, the membrane sealing the air vent. The membrane is formed of a material to prevent fluid from passing therethrough.

Abstract: An example device includes a frame having at least one outer opening and at least one inner opening recessed from the outer opening, at least one filter screen mounted on a perimeter of the at least one inner opening to form an inner chamber, at least one cover layer mounted on a perimeter of the at least one outer chamber to form an outer chamber, and a series of bubblebreaking features positioned within the inner chamber. The bubble-breaking features are positioned along a depth and a height of the inner chamber. The filter screen separates the inner chamber from the outer chamber, and the filter screen prevents froth from crossing and allows coalesced fluid to cross into the outer chamber.

Abstract: Various embodiments of a printer including an actuation member are disclosed.

Abstract: A hand-held printing device has a hand-operated mechanical actuator for moving a print head that prints images to medium and memory configured electronically storing a sequence of images in a predetermined sequential order. The hand-held printing device further has logic that detects a first actuation of the actuator and automatically communicates a first image in the sequence to the print head and detects a second actuation of the actuator and automatically communicates a second image in the sequence to the print head.

Abstract: A hand-held printing device having a hand-operated actuator that moves a print head relative to a print medium and at least one sensor. The hand-held printing device further has logic configured to perform at least one power-using operation of the hand-held device based on an output from the at least one sensor.

Abstract: Various embodiments of a printer including an actuation member are disclosed.

Abstract: Methods and apparatuses are provided for use inkjet pens. One method includes, during an initial stage of pen life, drawing ink from an ink reservoir through a standpipe, and, during an extended stage of pen life, allowing external air to enter into the standpipe through a standpipe bubbler and drawing ink from within the standpipe but not the ink reservoir.

Abstract: A replaceable ink supply comprises an ink container with an internal chamber formed from a plurality of walls. An ink reservoir block can be located within the internal chamber. Further, a channel can be formed in at least one wall of the internal chamber and the channel having an open side exposing a portion of the ink reservoir block.

Abstract: A multiple-layered membrane includes a gas permeable membrane layer, a printable surface layer having at least one aperture extending therethrough, and a non-contiguous adhesive layer coupling at least a portion of a first side surface of the gas permeable membrane layer to at least a portion of the printable surface layer, such that a part of the first side surface of the gas permeable membrane layer is exposed through the aperture in the printable surface layer.

Abstract: A fluid containment structure includes a containment vessel having an interior fluid chamber for fluid containment. A flexible bag is disposed within the containment vessel; the bag is vented to the external atmosphere outside the containment vessel. A spring is coupled to the bag to hold the bag in a coiled state until a back-pressure within the fluid chamber exerts sufficient force to commence uncoiling the bag against the spring pressure, allowing air from the external atmosphere to enter the bag and enlarge an interior bag space which is sealed from the interior fluid chamber.

Abstract: A fluid supply including a body and a reversibly fluid absorbing material having a first surface energy and disposed in the body. In addition, the fluid supply has at least one fiber having a fiber surface energy where the fiber is disposed within the fluid absorbing material, and the fiber surface energy is less than the first surface energy of the fluid absorbing material.

Abstract: A fluid containment structure includes a containment vessel having an interior vessel space for fluid containment, and a fluid outlet communicating with the interior vessel space. A flexible bag with opposed side surfaces is disposed within the containment vessel, vented to an external atmosphere outside the containment vessel. A sacrificial bond structure is formed between the side surfaces, and restrains the side surfaces together until a back-pressure within the vessel space exerts sufficient force to break the sacrificial bond structure, allowing air from the external atmosphere to enter the bag and enlarge an interior bag space.

Abstract: A heat stake head assembly includes a heating module including a heatable head surface, and a module head which includes a housing having a plurality of through receptacles formed between a first surface and a second surface. The module head is mountable onto the heating module such that the first surface is in contact with the heatable head surface. A set of stake tip elements are provided, each having a head end and a tip, each for fitting into one of the plurality of through receptacles such that the tips of the stake tip elements protrude from the second surface. A plurality of biasing structures bias a respective stake tip element into contact with the heatable head surface.

Abstract: An ink delivery apparatus includes a chamber configured to contain ink, where that chamber includes a proximal end for connection to the ink delivery apparatus, and opposing side portions having at least one tapered section configured to support the chamber and to facilitate at least partial controlled collapse of the chamber in response to a negative pressure.

Abstract: An ink delivery regulation apparatus includes a support configured to be positioned within an ink chamber and a resilient deflection member coupled to the support. The resilient deflection member is configured to resiliently deflect from a generally concave shape to a generally convex shape in response to a change in said negative pressure.

Abstract: An ink delivery apparatus includes a pressure tuned rolling piston having a distal end. The distal end includes a pressure responsive portion. A first convolute portion supports the pressure responsive portion, and the first convolute portion is configured to provide a first level of resistance against a negative pressure.
