Abstract: A depth camera assembly (DCA) determines depth information for a local area. The DCA includes a plurality of cameras and at least one illuminator. The DCA dynamically determines depth sensing modes (e.g., passive stereo, active stereo, structured stereo) based in part on the surrounding environment and/or user activity. The DCA uses the depth information to update a depth model describing the local area. The DCA may determine that a portion of the depth information associated with some of portion of the local area is not accurate. The DCA may then select a different depth sensing mode for the portion of the local area and update the depth model with the additional depth information. In some embodiments, the DCA may update the depth model by utilizing a machine learning model to generate a refined depth model.

Abstract: A spoiling apparatus for triggering a turbulent transition by autonomous disturbance and spoilers. The spoilers are mounted in multiple grooves in the circumferential direction of a navigating body, when a flow autonomously undergoes a turbulent transition, the spoilers remain in the grooves, the surface of the navigating body is free of protrusion, thus causing no additional flow resistance. A rated critical Reynolds number is set, in a case of a reduced flow speed and reduced density, the flow is a laminar flow, at which time the pressure applied to the spoilers by the flow is reduced, and the spoilers are ejected under the effect of compression springs. When ejected, the spoilers disturb the flowing of the bottom layer of the flow, and trigger the laminar flow into a turbulent flow.

Abstract: Systems and methods can allow for secure cross-device sharing of transient data using direct transient data sharing (“DTDS”). A source destination can share data using local DTDS with an agent on a first device. The agent can send the data to a hub server that runs a security control process and data formatting process.

Then an agent on the destination device can receive the transient data and use local DTDS to send the data to a destination application.
