  • Patent number: 12236661
    Abstract: A method of complementing a map of a scene with 3D reference points including four steps. In a first step, data is collected and recorded based on samples of at least one of an optical sensor, a GNSS, and an IMU. A second step includes initial pose generation by processing of the collected sensor data to provide a track of vehicle poses. A pose is based on a specific data set, on at least one data set recoded before that dataset and on at least one data set recorded after that data set. A third step includes SLAM processing of the initial poses and collected optical sensor data to generate keyframes with feature points. In a fourth step 3D reference points are generated by fusion and optimization of the feature points by using future and past feature points together with a feature point at a point of processing. This second and fourth steps provides significantly better results than SLAM or VIO methods known from prior art, as the second and the fourth steps are based on recorded data.

  • Publication number: 20250054527
    Abstract: Methods, systems, and devices for skipping pages for weak wordlines of a memory device during pre-programming are described. A memory device may be configured to operate in a first mode involving skipping one or more pages (e.g., a lower page (LP)) associated with a set of wordlines. In some examples, a testing system may determine the set of wordlines (e.g., weak wordlines) for which to skip pages according to performance degradation for the wordlines in response to applying a threshold temperature to a test memory device. In the first mode, the memory device may store (e.g., pre-program) data in a subset of pages distinct from the skipped pages. The memory device may switch to a second mode in response to a trigger condition. In the second mode, the memory device may use each page associated with the wordlines and may refrain from skipping the one or more pages.
