Abstract: An example device includes an array of electrodes for transporting droplets of fluids along dynamically configurable routes, the array having a first electrode that is selectively energized for moving a first fluid droplet toward the first electrode; a second electrode that is selectively energized for moving a second fluid droplet toward the second electrode; and further electrodes surrounding the first fluid droplet and second fluid droplet that can be selectively de-energized for maintaining separation between the first fluid droplet and second fluid droplet or selectively energized for merging the first fluid droplet and second fluid droplet.

Abstract: An integrated circuit to drive a plurality of fluid actuation devices includes a plurality of first memory cells, a plurality of first storage elements, and control logic. Each first memory cell stores a customization bit. Each first storage element is coupled to a corresponding first memory cell. The control logic, in response to a reset signal, reads the customization bit stored in each first memory cell and latches each customization bit in a corresponding first storage element.

Abstract: A die for a printhead is described herein. The die includes a number of fluid feed holes disposed in a line parallel to a longitudinal axis of the die, wherein the fluid feed holes are formed through a substrate of the die. A number of fluidic actuators are proximate to the fluid feed holes to eject fluid received from the plurality of fluid feed holes. The die includes logic circuitry to operate the fluidic actuators, wherein the logic circuitry is disposed on a first side of the plurality of fluid feed holes. Power circuitry to power the plurality of fluidic actuators is disposed on an opposite side of the fluid feed holes from the logic circuitry. Activation traces are disposed between each of the fluid feed holes to couple the logic circuitry to the power circuitry.

Abstract: An integrated circuit to drive a plurality of fluid actuation devices includes a plurality of memory cells, a select circuit, configuration logic, and control logic. Each memory cell corresponds to a fluid actuation device. The select circuit selects fluid actuation devices and memory cells corresponding to the selected fluid actuation devices. The configuration logic enables or disables access to the plurality of memory cells. The control logic either activates the selected fluid actuation devices or accesses the memory cells corresponding to the selected fluid actuation devices based on a state of the configuration logic.

Abstract: The present disclosure is drawn to imaging media. In one example, an imaging medium includes a substrate and a color-forming layer on the substrate. The color-forming layer includes a pattern of color-forming regions. Individual color-forming regions include multiple adjacently-applied leuco dyes in a colorless state. The leuco dyes are developable to generate color upon contact with developer compound. The imaging medium is devoid of developer compound.

Abstract: The present disclosure is drawn to imaging media. In one example, an imaging medium includes a substrate, a color layer on the substrate, and an opaque porous concealing layer over the color layer. The color layer includes a pattern of color regions, wherein individual color regions include multiple adjacently-applied colors. The opaque porous concealing layer has a coat weight from 2 gsm to 10 gsm. The opaque porous concealing layer includes transparent inorganic particles having a refractive index from 1.3 to 3, and void spaces between the transparent inorganic particles are occupied by air.

Abstract: An example of an imaging medium includes an image-receiving substrate, a donor ribbon attached to the image-receiving substrate, and a registration mark. The donor ribbon includes a donor ribbon substrate, a release layer disposed on the donor ribbon substrate, and a color-forming layer disposed on the release layer. The color-forming layer includes a repeated pattern. A repeat of the pattern includes at least three adjacent color-forming stripes including a cyan-forming stripe, a magenta-forming stripe, and a yellow-forming stripe, or a grid of four color-forming sections including i) a color-forming section selected from the group consisting of black-forming, cyan-forming, light cyan-forming, yellow-forming, magenta-forming, and light magenta-forming, ii) a cyan-forming section, iii) a magenta-forming section, and iv) a yellow-forming section. The color-forming layer is in contact with the image-receiving substrate.

Abstract: A fluid thermal processing device may include a substrate, a platform projecting from the substrate, a fluid heating element supported by the platform, a temperature sensing element, distinct from the fluid heating element, supported by the platform and an enclosure supported by and cooperating with the substrate to form a fluid chamber about the platform. The fluid chamber forms a volume of uniform thickness conforming to and about the platform.

Abstract: In one example in accordance with the present disclosure, a fluidic ejection die is described. The die includes an array of nozzles. Each nozzle includes an ejection chamber, an opening, and a fluid actuator disposed within the ejection chamber. Each nozzle also includes an inlet passage to deliver fluid into the ejection chamber and an outlet passage to deliver fluid out of the ejection chamber. The fluidic ejection die also includes an array of channels divided into inlet channels and outlet channels. Each inlet channel is fluidly connected to a respective plurality of inlet passages and each outlet channel is fluidly connected to a respective plurality of outlet passages.
