Abstract: Disclosed are methods, devices, apparatuses, and systems for poling a piezoelectric film. A poling system can be a corona poling system including a corona source with one or more corona wires configured to transfer a corona discharge onto a major surface of the piezoelectric film. The poling system can further include a grid electrode interposed between the corona source and the piezoelectric film. A substrate including the piezoelectric film may be supported on a substrate support, where the substrate and the corona source are configured to move relative to each other during poling.

Abstract: A notes service receives note items produced by various software applications. Each of the note items may comprise metadata, context data, and content representative of a note. The notes service, for each of the note items, stores a given note item in a note repository and updates a graph based at least on the metadata, the context data, and the content for the given note. As the notes service receives queries from the various software applications obtain relevant ones of the note items from the note repository, the service searches the graph for one or more note items relevant to a given query. The one or more notes are retrieved from the repository and provided in reply to the requesting application.

Abstract: An inline insertion viewport is provided. Aspects provide a preview of a content element within the context of a content authoring canvas prior to insertion of the content element into the canvas. Responsive to a selection of a functionality associated with inserting a content element into a canvas from within a content authoring tool user interface, an insertion viewport is displayed at an insertion point in the canvas, wherein the viewport comprises a preview of the content element. In a particular example, the user is enabled to utilize a camera functionality via the content authoring tool, wherein a preview of an image seen through the lens of a built-in or communicatively attached camera is displayed in the viewport, enabling the user to see how the content element looks within the context of the canvas prior to committing to capture and insert the content element in the canvas.

Abstract: Smart reminders are generated from input according to lexical and contextual cues. The input may be entered into any suitable application via any suitable electronic device. The input may be processed by a natural language processor to determine whether to convert the input into a smart reminder. In this way, the input of the note may be parsed to identify entities, such as entities associated with one or more people, relevant time(s), action(s), instruction(s), etc., for creating the smart reminder. The identified entities may then be used as triggers for displaying the smart reminder at an appropriate time to a user. A trigger such as detecting a person associated with the input, e.g., by receiving an incoming call from the person, connecting to the same network as the person, receiving a text from the person, or detecting the voice of the person, may cause the smart reminder to be displayed.
