Abstract: An example print component includes a container interface with a guide feature to guide rotation and a rotationally asymmetric key feature. An example toner component includes a recess to receive a toner container, a guide feature to guide rotation of the toner container, and an asymmetric key feature embedded in the guide feature to guide a container material interface towards a component material interface upon rotation. An example container may have a periphery with a rotationally asymmetric surface plane to guide rotation of the container and a protrusion extending from the periphery that has a key feature defined by edges rotationally asymmetric with respect to the periphery. An example container may include a mechanical interface including an asymmetrically-located key feature that, upon rotation of the print material container, generates a sealing force substantially perpendicular to the direction of rotation.

Abstract: This disclosure describes systems, methods, and computer-readable media related to retargeting online advertisement campaign recommendations for advertisements with multiple items or services. Bids may be based on a combined advertisement creative comprising two or more items or services. Dynamically selecting multiple items at bid time using a retargeting model to determine a potential revenue generation amount associated with an event may increase the probability of a conversion event based on the creative that includes the selected items. In some embodiments, a machine-learned retargeting model may be used to select multiple items to be displayed in an advertisement. The retargeting model may be applied to items that were previously viewed by the consumer and may determine a value for each of the items using factors. A bid may be calculated for each of the selected items using the values determined by the retargeting model.
