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: A modular chassis-based system may include a high speed backplane and multiple line cards. A connector connects the backplane to each line card for greater performance. The connector may include a stripline with a curved portion that transitions from the line cards to the backplane.

Abstract: A method for displaying base frames during video data decompression. A tuner selects a base frame of a compressed digital video data steam. The tuner decompresses the selected base frame prior to decompressing the remaining frames of the digital video data stream, and provides the decompressed base frame to a display device for display prior to the tuner decompressing the remaining frames of the compressed digital video data stream.
