Abstract: The present application relates to systems and methods for obtaining real-time abrasion data. An example computer-implemented method could include receiving, at a computing device, sensor data from one or more sensors. The one or more sensors are disposed in proximity to an abrasive product or a workpiece associated with the abrasive product. The one or more sensors are configured to collect abrasion operational data associated with an abrasive operation involving the abrasive product or the workpiece. The computer-implemented method could further include training, based on the sensor data, a machine learning system to determine product specific information of the abrasive product and/or workpiece specific information. The computer-implemented method could also include providing the trained machine learning system using the computing device.

Abstract: A video game with multi-axis multi-extremity control. In some embodiments separate extremity control is provided for two legs of a simulated character and movement of the legs affects motion of an inanimate object, for example a skateboard. In some embodiments multi-access multi-extremity control is provided only during a portion of video game play, and the portion may be experienced in slow motion.
