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.

Abstract: Aspects of the present disclosure are directed to providing assisted scene capture for an artificial reality (XR) environment.

Abstract: The present application introduces a membrane fouling warning methodology grounded in machine learning. It utilizes a machine learning-based membrane fouling prediction model to automatically forecast and generate electrochemical information values, which characterize the extent of membrane fouling at various time points, based on influent water quality parameters. It then acquires the electrochemical information values Zt at a moment t and Zt+?t at a moment t+?t. Subsequently, it computes and assesses the respective fouling levels using the electrochemical information values derived from the membrane fouling prediction model. Finally, it issues an early warning signal contingent upon the determined warning level. This methodology facilitates proactive understanding and management of membrane fouling, thereby sustaining the normal operation of the membrane fouling treatment system, mitigating the propensity for membrane assembly fouling, and prolonging the operational lifespan of the membrane assembly.
