  • Publication number: 20250020595
    Abstract: The present disclosure relates to a non-destructive in-situ measurement device and method based on Raman analysis. The device comprises: a laser light source that emits a laser beam; a focusing component that focuses the laser beam above a movable sample stage, with the focal plane of the focusing component positioned at an initial position. During measurement, the focal plane is controlled to move from the initial position to the surface, side, or bottom of the structure under test. The movable sample stage holds the sample to be measured and can move in a plane perpendicular and/or parallel to the optical axis. The axis of the structure under test is parallel to the optical axis and located within the laser beam's focal region. A detection module collects specific Raman scattering signals returned from the sample under test, and the structure's planar and three-dimensional parameters are determined based on the collected results.

  • Publication number: 20240361146
    Abstract: Systems and methods are directed to detecting uncontrolled intersections and providing warnings. In response to a navigation request from a user device, the system generates a navigation route using integrated map data, whereby the integrated map data includes indications of uncontrolled intersections that comprise intersections where at least some of the traffic is not required to stop. The system causes presentation of the navigation route in a user interface on the user device and monitors navigation of a vehicle associated with the user device along the navigation route. If the system detects that the vehicle is approaching an uncontrolled intersection based on the monitoring and the integrated map data, the system causes presentation of a warning indicating the uncontrolled intersection in the user interface.

  • Publication number: 20240264935
    Abstract: A method for data storage includes determining an expected expiration time of a new data file based on attribute information of the new data file and recorded attribute information of data files, in response to creation of the new data file in a level of a Log-Structured Merge Tree (LSM-Tree). Additionally, a block set corresponding to the expected expiration time is allocated for the new data file in a storage device. The recorded attribute information of the data files indicates a level where each of the data files is located, key information of each of the data files, and lifetime information of each of the data files. The data files that have been created comprise unexpired data files or both unexpired data files, and expired data files that expired within a preset period before creation time of the new data file.
