  • Publication number: 20240054661
    Abstract: A method for determining a trajectory of a vehicle within a physical space based at least on an aligned point cloud may include generating a fused feature map by concatenating a first feature map corresponding to a source point cloud and a second feature map corresponding to a target point cloud. A machine learning model may be applied to determine, based at least on the fused feature map, a relative transform aligning the target point cloud to the source point cloud. An aligned target point cloud may be generated by transforming the target point cloud in accordance with the relative transform. Furthermore, a trajectory of a vehicle within the physical space may be determined based on at least the first relative transform. Related systems and computer program products are also provided.

  • Patent number: 11143745
    Abstract: A radar target simulation device for testing a device under test with respect to at least one radar scenario. The radar target simulation device includes a memory, a radar scenario simulator and at least two antennas. The memory stores the radar scenario(s) with respect to the device under test, and provides the radar scenario(s) to the radar scenario simulator. The radar scenario simulator receives radar signals from the device under test via the antennas to simulate the radar scenario(s) by manipulating the radar signals according to the radar scenario(s), generates resulting manipulated radar signals, and transmits the manipulated radar signals to the device under test via the antennas. The memory contains storage contents including storage cells, wherein each storage cell corresponds to the respective antenna of the at least two antennas.

  • Publication number: 20210064714
    Abstract: Systems and methods for systems and methods for generating the complete set of IC design layout clips, or any part of the complete set, satisfying usefulness criteria and of a prespecified size. A method includes generating an initial set of integrated circuit (IC) design layout clips as a current set of IC design layout clips. The method includes removing any of IC design layout clips from the current set of IC design layout clips that do not meet the one or more usefulness criteria. The method includes, while a size of the IC design layout clips is less than a desired clip size, generating a new set of IC design layout clips from the current set of IC design layout clips according to every combination of pairs of the design layout clips in the current set of IC design layout clips, and repeating the removing process.
