Image formation with electroosmotic liquid removal

An image formation device includes a support, a fluid ejection device, and a first porous element. The support is to support movement of a substrate along a travel path, while the fluid ejection device is located along the travel path to deposit droplets of ink particles within a liquid carrier onto the substrate to at least partially form an image on the substrate. The first porous element is located downstream along the travel path from the fluid ejection device to be in contact against the substrate to remove, via electroosmotic flow through the first porous element, at least a portion of the liquid carrier from the substrate.

A DROPLET STEERING APPARATUS

An apparatus provides precise steering of inkjet droplets to a substrate by use of multipole arrangement with electrodes on a resistive plate. There may be droplet detection based on charge sensing. A hexagonal spiral deposition pattern on a target substrate allows fast uniform printing covering a nearly circular hexagonal area. There may be six electrodes arranged to form a cubic enclosure, and injected droplets may be merged within the enclosure, and their charge controlled by merging of source droplets of differing charges to provide a net charge for biasing onward steering.

ELECTROHYDRODYNAMICALLY FORMED STRUCTURES OF CARBONACEOUS MATERIAL

A method for the electrohydrodynamic deposition of carbonaceous materials utilizing an electrohydrodynamic cell comprising two electrodes comprised of a conductive material, by first combining a solid phase comprising a carbonaceous material and a suspension medium, placing the suspension between the electrodes, applying an electric field in a first direction, varying the intensity of the electric field sufficiently to drive lateral movement, increasing the electrical field to stop the lateral transport and fix the layers in place, then removing the applied field and removing the electrodes. Among the many different possibilities contemplated, the method may advantageously utilize: varying the spacing between the electrodes; removing the buildup from one or both electrodes; placing the electrodes into different suspensions; adjusting the concentration, pH, or temperature of the suspension(s); and varying the direction, intensity or duration of the electric fields.

METHOD FOR ASSIGNING COMMUNICATION ADDRESSES
20190092005 · 2019-03-28 ·

A production system such as an inkjet printer system includes a plurality of communication distribution devices connected in a daisy chain arrangement. A plurality of secondary devices, such as printhead electronics boards for inkjet printheads, is connected to each of the communication distribution devices. A first communication distribution device which is connected to a system controller assigns a communication address to itself from a first set of communication address and assigns communication addresses to its connected secondary devices from a second set of communication addresses. It then communicates information to the next communication distribution device specifying the next available communication addresses. This process continues down the chain of communication distribution devices. The assigned communication addresses are then transmitted to the system controller. The assigned communication addresses enable the system controller to determine the relative physical locations of the communication distribution devices and secondary devices.
