Abstract: A learning system capable of adaptively presenting various learning materials of various concepts to a user may include a concept tracker to analyze the learning materials and track one or more concepts from each of content items in the learning materials. A content item may be a video, and the system may analyze the transcripts of the video to determine one or more concepts about the video. The learning system may recommend a concept for the user to learn or improve based on the user's understanding and knowledge level around relevant concepts. Further, the system may present learning materials about the recommended concept to the user by indexing video segments by the time stamps associated with the particular concept and replay the video segments from the respective starting position and the ending position without replaying the entire video contents. Various clustering methods may be used to track the concepts.

Abstract: Instruments having plugs with data carriers containing codes identifiable as being correlated. The codes can be individual identifiers that are individually provided to the plugs. If plugs identical in construction of instruments of identical types are connected with apparatus or an apparatus group, e.g., a first plug of a used instrument and a second and third plug of a new instrument that replace the used instrument, the three inserted plugs are determined as not being part of the same instrument and an operation of the apparatus and thus the instruments is blocked.

Abstract: An educational system may include a contextualizer that accesses and processes content items and build a knowledge base including educational content and relationships between content items. The system may include a user assessor unit that determines user assessment variables based on user responses to previous educational content items and generate a user model based on the user assessment variables. The system may include a recommender that navigates the knowledge base and generates recommendations of new educational content based on the user model. The recommendation can assess the user's proficiency on a given concept based on the user model and maximize the user's probability of success around the concept of which the user shows proficiency, or improve the user's proficiency around the concept the user shows weakness. In some examples, the system may acquire an expert's knowledge about certain concepts to refine the user model, increasing the accuracy of the recommender.
