  • Publication number: 20260104498
    Abstract: One or more embodiments of the present disclosure relate to generating RADAR (RAdio Detection And Ranging) point clouds based on RADAR data obtained using one or more RADAR sensors disposed on one or more ego-machines. In these or other embodiments, the RADAR point clouds may be communicated to a distributed map system that is configured to generate map data based on the RADAR point clouds. In some embodiments of the present disclosure, certain compression operations may be performed on the RADAR point clouds to reduce the amount of data that is communicated from the ego-machines to the map system.

  • Publication number: 20250199149
    Abstract: One or more embodiments of the present disclosure relate to generation of map data. In these or other embodiments, the generation of the map data may include determining whether objects indicated by the sensor data are static objects or dynamic objects. Additionally or alternatively, sensor data may be removed or included in the map data based on determinations as to whether it corresponds to static objects or dynamic objects.

  • Publication number: 20060175734
    Abstract: An apparatus and process are provided for molding electronic devices in a mold, which apparatus comprises at least one runner in the mold connected to a mold supply pot for channeling a molding compound from the mold supply pot to the electronic devices. A plunger assembly is also provided that comprises a main body, and a supplementary body configured to be movable relative to the main body. The plunger assembly is locatable in the mold supply pot and is drivable in a direction towards the runner for forcing the molding compound into the runner. In order to avoid or reduce cull formation, a width of the runner at an opening connecting the runner to the mold supply pot is smaller than a width of the main body of the plunger assembly.
