Abstract: The present invention comprises a method and a system by which mobile, remote, adaptable controllers can dynamically control a multitude of resources within a given region (e.g. a room) such that policies determined for the region, controllers, and resources can be arbitrated in a manner that creates a meaningful work environment for users in the region. Furthermore, the present invention allows a controller to dynamically choose one of various modes of operation, either singly or in combination, allowing the user of the controller a maximum of flexibility in interacting with the resources in the region. These modes of operation comprise, but are not limited, to: a manual mode whereby a user may select a list of available resources that meet region-level policy and two automatic modes whereby controllers and resources may, without direct user input, make requests and allocation based on region-level policy and other constraints. The present invention maximizes the control of the resources of a region such that the control of the most suitable resources is dynamically situated in the hands of the user on an adaptable mobile controller.

Abstract: Low acoustic solid wave attenuation structures are formed with an electroformed nickel mold, and are incorporated within acoustic ink emitters, between the focusing lens and surface of an ink layer. The structures have characteristics of low attenuation of acoustic waves to increase the efficiency of acoustic wave transmission within the acoustic ink emitter. Using the described structures, acoustic ink printers can accurately emit materials having high viscosity, including hot melt inks.

Abstract: Techniques for obtaining an ejection rate independent, spatial relationship between an acoustic focal area and the free surface (12) of a liquid (14). Variations in the spatial relationship are reduced or eliminated by applying substantially the same acoustic energy to the liquid's free surface (12) during periods when droplets (20) are not ejected as when they are, but at power levels insufficient to eject a droplet (20). During ejection periods in which a droplet is not ejected, the acoustic energy is applied at a lower level, but for a longer time. Because it is more convenient to measure and control, the transducer (26) drive voltage is used to control the acoustic energy applied to the liquid's free surface (12).

Abstract: In accordance with the present invention, an acoustic ink printer comprises a pool of liquid ink having a free surface in intimate contact with the inner face of a perforated membrane. The printer addresses all pixel positions within its image field via substantially uniform, relatively large diameter apertures which extend through the membrane on centers that are aligned with respective ones of the pixel positions. In operation, one or more focused acoustic beams selectively eject individual droplets of ink from the ink menisci that extend across the apertures. Accordingly, the membrane is positioned and the bias pressure that is applied to the ink is selected so that the menisci essentially remain within the focal plane of such beam or beams.

Abstract: A printing system and method combine conventional print and reusable print media functionality in a shared stand-alone system to allow a user flexibility in deciding whether to print a temporary document or an archival permanent document. The system integrates and shares functionality to reduce manufacturing and operating costs, as well as to reduce the device's footprint. Commonality may include a common printhead shuttling mechanism (traversing carriage) and portions of the mechanism for moving paper. Pre-conditioning and printzone conditioning stations may also be shared to achieve precondition heating and/or erasing of media sheets prior to printing and maintaining of an elevated temperature during printing. In embodiments, separate feed trays are provided for each media sheet type.

Abstract: A multiple-ejector system for printing arrays of biofluids include a tooling plate having a plurality of sets of tooling pins extending outward from the surface of the tooling plate. A printed circuit board is provided having pairs of power connection pins and ground return pins extending from a surface of the circuit board. A plurality of biofluid drop ejection units are provided and include alignment grooves and at least a transducer. Each of the plurality of biofluid drop ejection units are connected to a corresponding one of a set of tooling pins by connection of the tooling pins and alignment grooves. The power connection pins of the pairs are in operational connection with respective transducers and the ground return connection pins of the pairs are in operational connection with a body portion of the drop ejection units. The different drop ejection units will contain different biofluids which are to be emitted onto a substrate. Verification of drop ejection units containing biofluids, may be obtained in one embodiment through the use of an optical scanner. Detection of drops at defined locations provides a verification that validates a properly formed spot is present on a substrate, and is in the correct position.
