  • Publication number: 20230314172
    Abstract: The present disclosure relates to a device for calibrating a laser level, including a base platform configured to support the laser level that is to be mounted at a first position of the base platform, a laser detector arranged at a second position of the base platform and configured to receive a laser, and an optical path extension device arranged at a third position between the laser level and the laser detector and configured to receive the laser emitted by the laser level and project the laser to the laser detector after the laser is adjusted by the optical path extension device. With the optical path extension device, a physical distance between the laser level and the laser detector can be optically extended. Without changing the physical distance between the laser level and the laser detector, the technical effect that the optical path distance between the laser level and the laser detector is enlarged can be simulated.

  • Patent number: 11775684
    Abstract: A rule-based attribution mechanism analyzes documents having different types of data in different formats through the application of script-based rules that apply a tag to the document identifying the type of sensitive data that is contained in the document. Documents having similar tags are aggregated so that the sensitive data is scrubbed from the document leaving the telemetric data available for downstream processing. The scrubbing entails different actions, such as, eliminating the sensitive data, obfuscating the sensitive data, and converting the sensitive data into a non-sensitive value.

  • Patent number: 11761764
    Abstract: The present disclosure discloses a method for using a laser level to track a detector and a laser tracking system. The method is applied to the laser level, which needs to use a fan-sweep mode or a dot-sweep mode. The method includes emitting a laser beam by the laser level to perform circular scanning, during the circular scanning, when the detector detects the laser beam, sending a detection signal to the laser level by the detector, when the laser level receives the detection signal, using the laser beam emitted by the laser level to perform circular scanning in an opposite direction, and when a frequency of the detection signal received by the laser level is greater than a first threshold, determining that the laser level tracks the detector.

  • Publication number: 20230281317
    Abstract: A false positive vulnerability system detects whether a software vulnerability identified by a static code vulnerability analyzer is a true vulnerability or a false positive. The system utilizes deep learning models to predict whether an identified vulnerability is accurate given the source code context of the identified vulnerability. A neural encoder transformer model is trained to classify a false positive given the method body including the identified vulnerability. A neural decoder transformer model is trained to predict a candidate line-of-code to complete a prompt inserted into the context of the identified vulnerability. The candidate line-of-code that successfully completes the prompt is used as a signal to identify that the identified vulnerability is a false positive.
