Abstract: A manufacturing method of an assembly injection molded article includes: preparing a first injection molded member; inserting insertion members into insertion holes of the first injection molded member to form an intermediate assembly; placing the intermediate assembly on a mold core of an injection molding mold, in which the mold core has in-mold insertion holes, and the insertion members are inserted into the in-mold insertion holes; and forming a second injection molded member on a side of the first injection molded member opposite to the mold core through the injection molding mold such that the first injection molded member, the insertion members, and the second injection molded member are assembled together. The present disclosure also provides an assembly injection molded article. The advantage of the present disclosure is to avoid burrs formed at seams between the insertion members and an appearance surface of the assembly injection molded article.

Abstract: A system and method for providing playback of interactions on a computing device. The system is configured to provide a user of a computing device with the capability of playing and/or recording walkthroughs on a user interface of the computing device, wherein the user is able to directly interact with the walkthrough and user interface in real- or near real-time during playback of the walkthrough. The walkthrough may be tutorial-based, such that the user may follow along with the walkthrough when attempting to answer a question or solve a problem via the user interface (e.g. classroom lesson on solving equations). The system is further configured to allow the user to record and generate a customized walkthrough.

Abstract: A system and method for generating and manipulating one or more curves in a dynamic graph in response to user input. The system provides a user interface for interacting with (e.g. manipulating) curves in a dynamic graph of a drawing program. In response to user input (e.g. interaction with the graph and/or curve therein), the user interface graphically generates and/or modifies the curve. Generation/modification of the curve is based on an algorithm configured to intuitively and dynamically move control points of the curve in response to the user input. The user input may include direct interaction with portions of the curve itself, as well as direct control of the end points and/or control points. The algorithm ensures that the generated/modified curve represents a valid mathematical function, while further ensuring that the generated or modified curve appears visually smooth.
