Abstract: A fluid-ejection device includes a handheld and/or mountable enclosure, a removable tip having a fluid-ejection mechanism, a first fitting extending from the enclosure and receptive to placement of the removable tip thereon, and a controller situated within the enclosure to cause the removable tip to eject the fluid. The fluid-ejection device may also include tip-extension assembly having an electrical cable connecting to the controller and having a second fitting receptive to placement of the removable tip thereon. The electrical cable permits the removable tip to be located substantially independently of the enclosure. The fluid-ejection device may further include tubings fluidically couplable with the removable tip through at least one of the first and second fittings to provide fluid to the removable tip and to regulate backpressure of the fluid within the removable tip.

The body of the tip has a second end at which a fluid-ejection mechanism is disposed to eject the fluid as controlled by the fluid-ejection device. The fluid may be introduced into the substantially hollow body of the tip through of the fluid-ejection mechanism disposed at the second end of the body of the tip. The tip may further be identified and/or serviced, and the tip and/or the fluid-ejection device may further be validated.

The controller is situated within the enclosure to cause the tip to eject the fluid via the electrical coupling of the electrical connectors of the tip and the fluid-ejection device.

Abstract: A peristaltic pump includes a plurality of occlusion surfaces and a plurality of rotors. The plurality of occlusion surfaces include a first occlusion surface and a second occlusion surface. The plurality of rotors includes a first rotor configured to be rotated about an axis and carrying a first set of occluding surfaces and a second rotor configured to be rotated about the axis and carrying a second set of occluding surfaces. The first set of occluding surfaces and the second set of occluding surfaces have a staggered pitch.

The fluid may be introduced into the substantially hollow body of the tip through of the fluid-ejection mechanism disposed at the second end of the body of the tip. The tip may further be identified and/or serviced, and the tip and/or the fluid-ejection device my further be validated.

Abstract: A device and method for delivering a pharmaceutical composition. The device includes an electronically controllable jetting device in communication with a source of a pharmacologically active material and a solid or fluidic mixing medium for receiving the ejected pharmacologically active material and directing it toward an end use destination.

Abstract: A fluid-gas separator includes a gas-permeable membrane arranged sufficiently adjacent to a fluid-permeable membrane to allow the separation of fluid and gas flowing therein independent of the orientation of the fluid-gas separator itself.

Abstract: In a recirculating inkjet print recording method and system, ink is stored at an ink supply. Fluid, including ink, is carried from the ink supply to a reservoir. Ink received from the reservoir is recorded onto a medium. Fluid, including ink and air, is carried from the reservoir to the ink supply. A proportion of ink in the fluid carried from the reservoir to the ink supply self-adjusts to prevent overfilling the reservoir.

Abstract: A manufacturing method provides ink-jet writing engine modules for use with a compatible hard copy engine module, a hard copy apparatus based thereon, and methods of manufacturing, operation, and use. Fluidic and electronic partitioning for ink-jet hard copy apparatus is redefined. Modular separation of a hard copy engine from a writing engine allows a replaceable writing module containing all of the key elements of the ink-jet writing system based on writing system technology requirements, particularly for those most likely to age or fail as a result of time, frequency of use, or end-user actions.

Abstract: A controller is provided for an inkjet airbrush system which uses inkjet printing technology for color mixing in airbrush painting, and for other fluid application systems. The controller is used to select a desired fluid blend or custom color which is blown by the inkjet airbrush onto an object. Firing signals, generated in response to the controller input, cause a printhead to eject a custom blend of colors which are combined in a mixing chamber and then atomized. The controller may be a remote device, or provided on-board the inkjet airbrush unit, preferably, as a joystick toggling device. The amount of colorant passing through the airbrush may be varied by varying the firing signal frequency in response to joystick motion or a separate adjustment mechanism. The inkjet airbrush system provides fast color changes and faster clean-up than conventional airbrushes. A method of controlling an inkjet airbrush is also provided.

Abstract: An inkjet airbrush system uses inkjet printing technology in a new manner for color mixing in airbrush painting. A variety of different configurations are used to generate atomized custom colors which are blown by the inkjet airbrush onto an object. In response to firing signals, a printhead ejects a custom blend of colors which are combined in a mixing chamber and then atomized using any type of atomizer desired. The firing signals may be generated by a remote device, such as a computer, or they may be generated on-board the inkjet airbrush in response to a user input, such as a code selected from a color chart. The amount of colorant passing through the airbrush may be varied by varying the firing signal frequency. The inkjet airbrush provides fast color changes and faster clean-up than conventional systems. A method of applying a fluid on an object is also provided.
