  • Publication number: 20190322287
    Abstract: A device receives quantitative data from sensors associated with an autonomous vehicle traveling on a road with other vehicles and from other sensors, and processes the quantitative data, with a first model, to determine distances between the autonomous vehicle and the other vehicles. The device processes the quantitative data, with a second model, to determine relative orientations between the autonomous vehicle and the other vehicles, and generates a conceptual neighborhood graph, based on a third model. The device identifies a subset of the conceptual neighborhood graph, and determines relative trajectories between the autonomous vehicle and the other vehicles based on the distances, the relative orientations, and the subset of the conceptual neighborhood graph.

  • Patent number: 9496727
    Abstract: A rechargeable battery pack is discontinuously charged in multiple discrete charging intervals. Reductions in battery pack voltage that occur during non-charging intervals, each transpiring between a respective pair of the discrete charging intervals, are measured. Multiple resistance values that characterize the internal resistance (DC resistance) of the battery pack are generated based on the reductions in battery pack voltage that occur during the non-charging intervals.
