Abstract: The present disclosure relates to the field of resource-oriented utilization technologies for wastewater salt muds and more particular to a resource-oriented utilization method for a high-salt salt mud containing sodium chloride and sodium sulfate. The method includes: performing two stages of oxidation, i.e. Fenton-like treatment and chlorine dioxide treatment, in sequence on a salt mud solution, and then replacing a sodium salt with an ammonium salt to prepare a pure alkali and a mixed ammonium salt. In the method, multi-stage oxidation process is performed to effectively use ingredients such as sodium chloride and sodium sulfate so as to thoroughly eliminate organic matters and heavy metals in the high-salt salt mud, and achieve resource-oriented utilization of the salt mud, thus saving burial treatment costs, and producing good economic benefits as well as good environmental benefits.

Abstract: An augmented reality (AR) device generates hand annotations for an image depicting a user's hand. The device includes a display, a processor, and a memory storing instructions for performing operations. The device performs a calibration operation to generate a 3-D model of the user's hand based on measurements. The calibration operation prompts the user to mimic the hand gesture presented by the animated virtual representation of a hand to obtain optimal images of the hand for hand pose estimation. A 3-D virtual representation of a hand in a hand pose corresponding with a hand gesture is generated based on the 3-D model. The device presents the 3-D virtual representation of the hand in AR via the display. During presentation, the device detects an input and captures an image of the user's hand positioned to correspond with the 3-D virtual representation. The captured image is stored with corresponding hand annotations based on the 3-D model.

Abstract: Software applications often incorporate an embedded browser to perform web-based operations. Not all browsers operate the same way, for example, elements within tabs in Microsoft Edge browsers use messages to communicate through web extensions, while Microsoft Internet Explorer (IE) browsers use the original browsers helper object (BHO). A consequence of the different paradigms is that certain graphical elements may be duplicated in a resource table. A test development may fail to identify the duplication and may produce extraneous or erroneous tests. By launching on a system and monitoring the system's executing processes, a browser application may be determined to be running and, if so, a refresh operation is performed on an application under test (AUT). If the AUT refresh operation results in a browser also performing a refresh, the type of embedded browser may be identified and any duplicates of the same graphical elements identified and merged for subsequent testing.

Abstract: A head-worn device system equipped with cameras, display devices, and processors uses stored instructions to facilitate interactions between an augmented reality (AR) device and an external display system. When executed, these instructions establish a communications link between the AR device and the external display. The system identifies the pose of the external display and receives user inputs from the AR device user, relating to interactions with virtual objects in a real-world setting. It also identifies the positions of viewers watching the external display. Based on the external display's pose and the viewer locations, the system generates display data for the virtual object, ensuring it appears correctly on the external display. This display data is then transmitted to the external display system, completing the interaction loop and enhancing the viewing experience for the audience.
