Abstract: An electrical stimulation system includes an electrical stimulation circuit and a controller. The electrical stimulation circuit includes a flyback transformer connected to electrical stimulus outputs, and a switch having a control input. In some instances, a controller is connected to the control input, and generates a stimulus signal. The flyback transformer outputs an electrical stimulus event responsive to the stimulus signal onto the electrical stimulus outputs. In some instances, pulses operate to charge the flyback transformer to a saturation mode. In some further instances, a diode and capacitor arrangement electrically connected at a secondary side of the flyback transformer facilitate delivery of the electrical stimulus event at the electrical stimulus outputs.

Abstract: The technology described herein uses local computing resources, rather than remote resources (e.g., server based), to provide a result upon determining that the local resource is capable of providing the result with above a threshold quality. When a local machine-learning model is not capable of providing the result with above the threshold quality, then a remote machine-learning model may be used to provide the result. A goal of the technology is to select the most efficient resource to provide a result without significantly compromising the quality of the result. The technology described herein makes a series of determinations to identify one or more machine-learning model results that may be provided locally with or without hybrid resources. Different machine-learning model results may be provided using different hybrid workflows. In aspects, a remote result and a local result are generated and ranked by the client.

A method of operating such a regeneration system is also provided.

Abstract: For artificial reality (XR) applications that need a guardian, aspects of the present disclosure can automatically determine where boundaries should be set in the real-world environment. Using a machine learning model, the automatic boundary system can detect the floor plane, then generate a height map of the real-world environment with the floor at zero. The height map can include positive heights (e.g., objects on the floor) and negative heights (e.g., downward leading stairs). The automatic boundary system can then generate a boundary for the area based on the detected heights by: applying thresholds to disregard objects at certain heights, applying thresholds to disregard open areas at certain widths, excluding oddly shaped areas that would constantly trigger the boundary if the user were nearby, etc. The user can further manually adjust the generated boundary in both directions (e.g., bringing it closer or further from the user).

Abstract: Independently moving deployment and positioning space vehicles that are configured to deploy and/or position structures are disclosed. The deployment and positioning vehicles may provide a lighter weight, more flexible, and more reliable deployment and positioning system that enables the deployment of space structures that are potentially much larger than currently possible with mechanical components of the structure itself. The deployment and positioning vehicles could be used for removal of failure prone deployment mechanisms for spacecraft. Solar arrays, antennas, panels, instrument booms, etc. could be pulled open and locked into place, and then potentially repositioned and/or reoriented during a mission.

Abstract: Instead of having a constant boundary, artificial reality (XR) applications that can run in boundaryless mode (e.g., in augmented or mixed reality) can be given controls by selective boundary system on an XR system to customize partial boundaries. For example, an application can specify to select particular boundaries when certain object types are in the real-world environment. In another example, an application can transition to different boundary modes when certain application events occur (e.g., when transitioning from virtual reality to mixed reality). On the backend, the selective boundary system can provide the application with an API that exposes boundary information. Based on this information, the application can use the API to create new boundaries or turn on or off certain boundaries based on requests by the application.
