Abstract: In various examples, a printbar is formed from multiple modular fluid ejection subassemblies joined together through a molding process that provides for a continuous planar substrate surface. A mold may secure the modular fluid ejection subassemblies during a molding process in which a runner conveys a molding material to seams between the joined modular fluid ejection subassemblies.

Abstract: User interfaces for indicating time, displaying a user interface based on a day of the week, user interfaces that include a dynamic text string, user interfaces that include a customizable border complication, user interfaces that include a watch hand that changes color at predetermined times, and user interfaces that include a simulated lighting visual effect.

Abstract: An example digital microfluidic device can include a hydrophobic electrowetting surface including an array of electrodes. The individual electrodes can have a shape with three or more sides. The array of electrodes can include a parking electrode and an adjacent electrode that is adjacent to the parking electrode. A cover can be positioned over the electrowetting surface at a gap distance sufficient to accommodate a liquid droplet between the cover and the electrowetting surface. A plurality of droplet barriers can be positioned on three or more sides of the parking electrode. The droplet barriers can constrain movement of a liquid droplet from the parking electrode to the adjacent electrode.

Abstract: A computer-implemented method for clinical workspace simulation includes capturing a real-world environment by an imaging device of an augmented reality headset and generating a composite view by rendering a first virtual object relative to a surgical table in the real-world environment. Captured real-world environment and the rendered first virtual object are combined in the composite view, which is displayed on a display of the augmented reality headset worn by a user.

Abstract: A process for producing copolymers of ethylene and butene-1 wherein the butene-1 comonomer is generated in situ within the polymerization reactor by a separately catalyzed ethylene dimerization reaction.
