Abstract: A privacy enabled system for managing clinical study participant travel has a database (stores data: clinical study, participant, clinical site and trip data sets) and a graphical user interface that has a Travel Planning Interface and is in data communication with an input device and the database. The data sets include a Study Travel Policy, a Study Visit Schedule (appointment procedure, appointment schedule), a traveler profile, traveler personal data (traveler contact information), a site appointment location associated with the appointment procedure, and site contact information. The travel planning interface receives the trip data set (trip segment data) from the database and the input device. The travel planning interface transmits the trip segment data to and receives booked travel data from a travel booking module, generates an itinerary that has booked travel and trip segment data, and transmits the itinerary according to the traveler contact information and the site contact information.

Abstract: Systems for visualization and management of a travel policy for a clinical study have a study dataset having a first travel policy condition, a study travel policy dataset having a main travel policy and a specialized travel policy, and a GUI having a travel policies interface and a travel policy control. The first travel policy condition may be a country, a clinical site, a traveler policy label, a visit attribute, a visit policy label, and combinations thereof. The specialized travel policy (a country policy, a site policy, a first visit policy, a second visit policy, a custom policy, and combinations thereof) is programmatically associated with the first travel policy condition.

Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of ink. An interior retains the ink while exit and return ports define openings through a housing to fluidly communicate the interior to the imaging device. The opening of the return port is larger than the opening of the exit port. The design slows the return of fluid to the housing which minimizes air bubbles or frothiness in the fluid. During use, ink depletes toward a bottom surface of the interior beneath which the ink is prevented from occupying. A housing section below the interior retains a portion of the exit port so that a bottom of the opening of the exit port is substantially horizontally aligned with the bottom surface. It prevents stranding ink beneath the exit port. Further embodiments include port configuration, construction, and modular components, to name a few.

Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of fluid. Its housing defines an interior having a pair of opposed electrodes. The electrodes define a capacitance that varies in response to an amount of liquid between them. A volume space filled by the liquid varies along a length of the electrodes. The design facilitates abrupt changes in capacitance values at each change in the volume space. Devices can recalibrate fluid levels at these changes. Electrode interior surfaces face one another. At least one electrode has an open region, such as a hole or a cutout of material. In another design, a support material connects to each electrode to provide mechanical stability and create a region preventing filling by the liquid. Further embodiments contemplate material selection, construction, and modularity, to name a few.

Abstract: A housing defines a fluid reservoir for an imaging device. One or more exterior walls define a volume for holding ink to set a fluid backpressure in the imaging device. An opening in the walls is positioned for overflowing excessive ink from the volume to maintain the fluid backpressure within a predetermined operating range. Fluid inlets and outlets connect the reservoir to both a supply item and an ejection head. Ink flows into the reservoir from the supply item. It fills until the fluid rises to a height where it overflows back to the supply item. Less full reservoirs fill as the pump operates, while full reservoirs simultaneously return fluid back to their supply containers. Fluid does not spill from the walls.

Abstract: A replaceable tank for attachment to a micro-fluid ejection head containing a multi-function thermoplastic elastomer layer, a method for sealing an exit port of a removable fluid reservoir for a micro-fluid ejection head using the multi-function thermoplastic elastomer layer, and a method for improving the handling and shipping of replaceable fluid cartridges for micro-fluid ejection heads using the multi-function thermoplastic elastomer layer. The multi-function thermoplastic elastomer layer is disposed in the exit port and on at least a portion of an outer surface of the reservoir.

Abstract: A printhead assembly includes a printhead body including at least one printhead having a wick associated therewith, and a shipping reservoir. The shipping reservoir is operable to releasably engage the printhead body and includes at least one vented ink container for retaining ink. The shipping reservoir is engaged in the printhead body during shipment so that the wick and ink flow channels with the at least one printhead remains moist while the shipping reservoir is engaged in the printhead body.

Abstract: An ink cartridge comprising: (a) an ink cartridge body including a floor and an exterior wall partially defining an interior volume, the ink cartridge body including a capillary producing medium; and (b) an ink cartridge cap mounted to the ink cartridge body to substantially enclose the interior volume, the ink cartridge cap including two vents in direct communication with the interior volume, wherein a first vent incorporates an ink supply port. The invention also includes the utilization of a universal ink tank lid for use both in replacement and starter ink tank configurations, as well as methods of utilizing a universal ink tank lid to reduce production costs and complexities.

Abstract: Ink tanks and recording devices incorporating the ink tanks comprise a free ink chamber, and a negative pressure generating chamber in the ink tank. The negative pressure generating chamber comprises a floor member comprising at least one projection extending along at least a portion of the floor member, and a porous material, wherein the projection of the floor member is configured to engage the porous material to inhibit the creation of an air flow path between the porous material and the floor member. The ink tank further comprises a partition wall disposed between the free ink chamber and the negative pressure generating chamber and configured to allow the flow of ink from the free ink chamber to the negative pressure generating chamber.

The ink tank comprises a negative pressure producing material containing chamber and a free ink chamber. A lid configured to seal the negative pressure producing material containing chamber and free ink chamber of the ink tank is adapted to reduce the volume of the ink tank from a first capacity to a second capacity of ink. A method of manufacturing the same is provided.

Abstract: Some embodiments of the present invention provide an inkjet printhead within which a removable ink cartridge can be installed. Upon installation, the ink cartridge can be coupled to one or more wicks in the printhead for establishing fluid communication between one or more chambers in the ink cartridge and nozzles through which ink exits the printhead during operation. The wick can extend from a cartridge receptacle to a filter in order to transport ink from the removable cartridge to the filter. In some embodiments, the wick is retained in place within the printhead by a cap, which can be coupled to one or more filter towers. The wick can have upstream and downstream interfaces that can be the same or different in shape and/or size.

Abstract: An inkjet assembly comprising a vented ink reservoir for containing a liquid ink therein, the vented ink reservoir defining an internal volume occupied at least in part by a semipermeable membrane in fluid communication with a vent that automatically adjusts for pressure differentials by enabling gaseous diffusion between an environment external to the vented ink reservoir and the internal volume of the vented ink reservoir, while inhibiting liquid diffusion therethrough. A method is also disclosed for mounting the semipermeable membrane to at least one of an ink reservoir cap and an ink tank.
