Abstract: In one example in accordance with the present disclosure, a fluidic die assembly is described. The fluidic die assembly includes a rigid substrate having a bend therein. A fluidic die is disposed on the rigid substrate. The fluidic die is to eject fluid from a reservoir fluidly coupled to the fluidic die. The fluidic die includes an array of ejection subassemblies. Each ejection subassembly includes an ejection chamber to hold a volume of fluid, an opening, and a fluid actuator to eject a portion of the volume of fluid through the opening. The fluidic die assembly also includes an electrical interface disposed on the rigid substrate to establish an electrical connection between the fluidic die and a controller. The fluidic die and the electrical interface are disposed on a same surface on opposite sides of the bend.

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 layer disposed on the release layer. The color layer includes a repeated pattern. A repeat of the pattern includes at least adjacent color stripes including a cyan stripe, a magenta stripe, and a yellow stripe, or a grid of four color sections including i) a colored section selected from the group consisting of black, cyan, light cyan, yellow, magenta, and light magenta, ii) a cyan section, iii) a magenta section, and iv) a yellow section.

Abstract: An electroporation system may include a well plate, a dispenser and a dispenser-well positioning system. The well plate may include wells, each of the wells including an interior, a first electrode adjacent the interior and a second electrode adjacent the interior and spaced from the first electrode. The first electrode and the second electrode are to apply an electrostatic field across the well. The dispenser is to dispense a cell having a diameter into each of the wells. The dispenser-well positioning system is to align each well and the dispenser such that the dispenser dispenses the cell into each well at a location spaced from the first electrode and the second electrode by a distance of at least 5 times the diameter of the cell.

Abstract: A fluidic die may include a number of actuators. The number of actuators form a number of primitives. The fluidic die may include a digital-to-analog converter (DAC) to drive a number of the delay circuits. The delay circuits delay a number of activation pulses that activate the actuators associated with the primitives to reduce peak power demands of the fluidic die. A number of delay circuits may be coupled to each primitive.

Abstract: One example includes a device that includes an insulator panel, a plurality of electrical inputs, and a plurality of electrodes. The plurality of electrical inputs may be disposed on the insulator panel and individually receive an actuation voltage. The plurality of electrodes may be disposed on the insulator panel and are coupled to the plurality of electrical inputs. Two or more of the plurality of electrodes may be coupled to a single one of the plurality of electrical inputs for each of the plurality of electrical inputs. The plurality of electrodes may be actuated with the actuation voltage individually received at a respective electrical input to create an electric field over associated electrodes to subject a droplet proximate to the associated electrodes actuated with the actuation voltage to an electrowetting force.

Abstract: Aspects relating to an ink container for an image reproduction device are described herein. The ink container includes a body and an electrical connection. The body is formed by molding a polymer material having a metal seed layer. The electrical connection is formed by metallizing a plurality of traces in the metal seed layer. The electrical connection extends from an inside wall of the ink container to an outer wall. A width of the electrical connection on the inside wall of the ink container gradually varies from a bottom of the ink container to a rim.
