Abstract: Techniques for a motion-based online interactive platform are described. The platform makes a motion-based online class realistic and allows a teacher to visualize motions performed by a student in a perspective and how close the motion is in view of an authoritative instructor (model). Depending on implementation, the platform may be implemented as an application, a Teacher App or a student App. Each may be executed in a computer or control computer associated with an instructor or teacher or computing devices associated with students. Each of the computing devices is coupled to or includes a camera, where the camera is used by a student to show his presence or poses he performs. Data streams from the computing devices are received in the control computer, where each of the data streams includes a video and a set of sensing data. A 3D avatar of a student is generated from the sensing data in the control computer. The video is not used for generating the avatar.

Abstract: Techniques for capturing motion of a user are described. A plurality of sensor modules corresponding to a set of designated body parts (e.g., arms or legs) of the user generate sensing signals when the user performs a pose. Sensing data including accelerometers and/or gyroscopes data produced from the sensing signals is analyzed to derive various moves made by the user, where an human avatar animation is provided and displayed based on motion attributes derived from the sensing data.

Abstract: Embodiments of the present invention provide fine grain concurrency control for transactions in the presence of database updates. During operations, each transaction is assigned a snapshot version number or SVN. A SVN refers to a historical snapshot of the database that can be created periodically or on demand. Transactions are thus tied to a particular SVN, such as, when the transaction was created. Queries belonging to the transactions can access data that is consistent as of a point in time, for example, corresponding to the latest SVN when the transaction was created. At various times, data from the database stored in a memory can be updated using the snapshot data corresponding to a SVN. When a transaction is committed, a snapshot of the database with a new SVN is created based on the data modified by the transaction and the snapshot is synchronized to the memory.

Abstract: A scalable solution to managing congestion in a network is disclosed. In one implementation, such a solution comprises a means for managing traffic including at least one flow monitor and a plurality of flow control regulators that together manage congestion within a network. Each of the flow control regulators monitor traffic at a corresponding ingress point and determine a state of the ingress point corresponding to the traffic monitored at the ingress point. Each flow control regulators forward the state (or information representative of the state) to the flow monitor. The flow monitor detects congestion based upon the states of the flow control regulators and, in the event of congestion, determines a target bandwidth for the ingress points. The flow monitor provides a control signal to at least one of the flow control regulators, and at least one of the flow control regulators control flows at its corresponding ingress point based upon the control signal received from the flow monitor.

Abstract: A scalable solution to managing fairness in a congested hierarchical switched system is disclosed. The solution comprises a means for managing fairness during congestion in a hierarchical switched system comprising a first level arbitration system and a second level arbitration system of a stage. The first level arbitration system comprises a plurality of arbitration segments that arbitrate between information flows received from at least one ingress point based upon weights associated with those information flows (or the ingress points). Each arbitration segment determines an aggregate weight from each active ingress point providing the information flows to the segment and forwards a selected information flow along with the aggregate weight (in-band or out-of-band) to the second level arbitration system.

Abstract: A processor reduces wasted cycle time resulting from stalling and idling, and increases the proportion of execution time, by supporting and implementing both vertical multithreading and horizontal multithreading. Vertical multithreading permits overlapping or “hiding” of cache miss wait times. In vertical multithreading, multiple hardware threads share the same processor pipeline. A hardware thread is typically a process, a lightweight process, a native thread, or the like in an operating system that supports multithreading. Horizontal multithreading increases parallelism within the processor circuit structure, for example within a single integrated circuit die that makes up a single-chip processor. To further increase system parallelism in some processor embodiments, multiple processor cores are formed in a single die. Advances in on-chip multiprocessor horizontal threading are gained as processor core sizes are reduced through technological advancements.
