Abstract: An imitation learning system may learn how to play a video game based on user interactions by a tester or other user of the video game. The imitation learning system may develop an imitation learning model based, at least in part, on the tester's interaction with the video game and the corresponding state of the video game to determine or predict actions that may be performed when interacting with the video game. The imitation learning system may use the imitation learning model to control automated agents that can play additional instances of the video game. Further, as the user continues to interact with the video game during testing, the imitation learning model may continue to be updated. Thus, the interactions by the automated agents with the video game may, over time, almost mimic the interaction by the user enabling multiple tests of the video game to be performed simultaneously.

Abstract: An insulating rotary diaphragm for a vacuum interrupter (VI) electrical switch. The insulating diaphragm is designed for use in underground or pad-mounted VI switches where an external lever is rotated by a line worker to manually open the switch. A torsional insulating rod is coupled between a switch actuator and the external lever, and the diaphragm maintains constant contact with the insulating rod and an outer housing when the lever and rod are rotated, thus ensuring adequate isolation between the actuator and the lever. The diaphragm deforms torsionally when the lever and rod are rotated. This configuration allows the actuator to be at medium voltage, eliminates the need for a translational insulating rod between the medium voltage switch components and the lever, and thereby reduces the overall length of the VI switch.

Abstract: Systems and methods are provided herein for charging an electric vehicle based on the inferred dwell time of a user of the electric vehicle. This may be accomplished by an electric vehicle charging station (EVCS) receiving a request from a user to charge an electric vehicle. The EVCS can use the request to identify a profile associated with the user, wherein the profile comprises user information related to the user. The EVCS then estimates a dwell time for the user using the user information. The EVCS can use the dwell time to estimate a total charge time for the electric vehicle. The EVCS then charges the electric vehicle based on the estimated charge time.

Abstract: Improved assessment of brain injuries, and improved brain injury management, is achieved using a combination of impact-related data derived from instrumented mouthguard devices, human function performance testing, and biomarkers derived from biological fluid (such as saliva and/or blood). The human function performance testing may include brain function performance testing, and/or other forms of human function performance testing. This involves combining a data-driven understanding of a head impact event (based on data collected via an instrumented mouthguard device) with a data-driven understanding of human function performance following that head impact event. The biomarkers may include salivary mRNA and/or ncRNA, and/or blood proteins (for example via a FDA-approved Brain Trauma Indicator test).
