Abstract: Systems and methods of the present invention provide for receiving, from a client, a request for a collaborative environment; displaying the collaborative environment; recording a plurality of attempt steps including events input by a learner to solve a problem, and solution steps input into the collaborative environment by an instructor, which identifies a timestamp within the plurality of events and generates alternative events solving the problem. The system then receives a request to reproduce the collaborative environment; and generates a reproduction of the collaborative environment.

Abstract: A media detection system receives a video corresponding to a fixed field of view. The media detection system may receive user input indicating one or more object types to identify or a subset of the video within which to identify objects. The media detection system applies one or more machine-learned classifiers to frames of the video and creates a summary video that includes the background of the video and identified instances for simultaneous playback within the fixed field of view. The media detection system may also identify instances of objects in a live video stream and use the identified instances to respond to user questions. The media detection system applies a language model to questions to identify the subject matter of the questions, identifies content within the live video stream associated with the subject matter, and uses the identified content to respond to the user's question.

Abstract: A medicament for dental procedures includes a first component comprising an oxidizing agent, and a second component comprising a calcium complexing agent, wherein when the first component is mixed with the second component, the pH is greater than 6.2. Kits including the medicament and methods of use of the medicament are disclosed.

Abstract: A learner engagement engine provides a unique way to track and measure a learner's engagement across a plurality of different learning resources. In preferred embodiments, the learning engagement engine measures learner's engagement activities at the most detailed level (such as at a paragraph level, instead of a chapter or book level). This allows the learner engagement engine to easily aggregate learner activities, even when a course structure or context are changed during the course.

Abstract: Systems and methods for an oven include a housing, a heating chamber positioned within the housing, an external nesting rack coupled to the housing, the external nesting rack is stationary while coupled to the housing, and a movable cook surface, the movable cook surface movable between a position completely within the heating chamber and a position at least partially external to the heating chamber, such that when the movable cook surface is in the position at least partially external to the heating chamber, the movable cook surface is positioned at least partially recessed below a top surface of the external nesting rack.

Abstract: A clutch assist apparatus that has a casing, a controller, a position sensor that communicates with the controller to identify the position of a hand lever, a motor controlled by the controller and coupled to the casing, a cable pulling lever pivotally coupled to the casing about a rotation axis and configured to be coupled to a clutch cable, the cable pulling lever being movable between a first position and a second position. Wherein, the cable pulling lever selectively transitions a clutch assembly between an engaged position when the cable pulling lever is in the first position and a disengaged position when the cable pulling lever is in the second position. Further wherein, the cable pulling lever is movable between the first position and the second position by either the motor or the hand lever.
