Abstract: Disclosed are systems and methods for inserting or injecting additional object identifiers into a currently presented feed or presentation of object identifiers. For example, a user of a portable device may view a feed or set of object identifiers, such as images of objects, that is presented on the display of the portable device. As the user views the object identifiers, the user may interact with one or more of those object identifiers by selecting an interaction control associated with the object identifier to indicate an interest in the object identifier. In response to the interaction, rather than presenting a new set of object identifiers, the described implementations insert or inject additional object identifiers into the current feed or set of object identifiers so that the user can continue to view the current object identifiers as well as the additional object identifiers.

Abstract: A digital magazine application associated with a digital magazine server executes on a client device and allows a user to interact with content from the digital magazine server even when the client device is unable to communicate with the digital magazine server. When the application detects loss of communication with the digital magazine server, interactions received by the application after the loss of communication has been detected are stored in a queue on the client device. When communication with the digital magazine server is reestablished, interactions from the queue are communicated to the digital magazine server. Certain interactions having less than a threshold measure of time dependency are stored in the queue in an order based on their associated timestamps, allowing the stored interactions to be later executed in an appropriate order by the digital magazine server.

Abstract: A container for holding endodontic instruments that may include a base, a foam pad, a retainer, and a lid. The base may include a well with a bottom and sidewalls extending upwardly from the bottom to an open-ended top. The foam pad may be configured to hold one or more endodontic instruments inserted through the pad, and dimensioned to cover the open-ended top of the well. The retainer may be configured to clamp the foam pad over the open-ended top of the well so that the pad is tautly maintained in a holding position, whereby the foam pad is configured to hold at least a portion of an endodontic instrument within the well. The lid may be coupled to the base, and movable between an open position and a closed position that covers the foam pad.
