摘要： Methods and systems for using a MEMS mirror for steering a LiDAR beam and for minimizing statically emitted light from a LiDAR system are disclosed. A LiDAR system includes a light source that emits a light beam directed at a MEMS device. The MEMS device includes a manipulable mirror that reflects the emitted light beam in a scanning pattern. The MEMS device also includes a substrate positioned adjacent to and at least partially surrounding the mirror. An attenuation layer is disposed on a top surface of the substrate and is configured to attenuate light reflected by the substrate.

摘要： A voltage generator supplies a voltage to an electronic device of a Light Detection and Ranging (LiDAR) system. The voltage generator includes a clock source configured to generate a clock signal and a voltage source configured to generate a first voltage signal having a first voltage level. The voltage generator also includes a voltage multiplier coupled to the voltage source and the clock source. The voltage multiplier is configured to generate a second voltage signal having a second voltage level based on the first voltage signal and the clock signal. The second voltage level is higher than the first voltage level.

摘要： Systems and methods are disclosed related to generating interactive user interfaces that enable a user to alter 3D point cloud data and/or associated pose graph data generated from LiDAR scans prior to generation of a high definition map. A user may make selections in a 2D map representation with overlaid graph node indicators in order to alter graph connections, remove nodes, view corresponding 3D point clouds, and otherwise edit intermediate results from LiDAR scans in order to improve the quality of a high definition map subsequently generated from the user-manipulated data.

摘要： Embodiments of the disclosure provide transmitters for light detection and ranging (LiDAR). The transmitter includes a laser source, a light collimator, and a beam shifter. The laser source is configured to provide a native laser beam. The light collimator is configured to collimate the native laser beam to form an input laser beam transmitting along a lateral direction. The beam shifter is configured to shift the input laser beam along a vertical direction perpendicular to the lateral direction by a displacement to form an output laser beam. The output laser beam and the input laser beam are parallel to each other.

摘要： Malicious processes may be tracked by obtaining process history information of a computing device and obtaining an identification of a malicious software on the computing device. An associated process of the malicious software and actions of the associated process may be identified based on the process history information. Related processes of the associated process and actions of the related processes may be iteratively identified based on the process history information. Tracking information for the malicious software may be generated based on the associated process, the actions of the associated process, the related processes, and the actions of the related processes.
