  • Patent number: 10816985
    Abstract: According to some embodiments, a system operates an ADV. In one embodiment, the system perceives a driving environment surrounding the ADV based on sensor data obtained from a plurality of sensors, including perceiving a moving obstacle that is moving relative to the ADV. The system projects the moving obstacle as a figure onto a station-time (ST) coordinate system, wherein the ST coordinate system indicates a distance between the figure and a reference point at different points in time. And the system, for each of a plurality of predetermined processing time intervals, determines two points of the figure in the ST coordinate system to represent a shape of the figure, wherein the shape of the figure is utilized to plan a trajectory to drive the ADV to avoid colliding with the moving obstacle.

    Abstract: A power supply system includes a wireless power supply end and a wireless receiving end. The wireless receiving end includes a resonant receiving component and a rectifying and voltage-stabilizing component that is connected to the resonant receiving component to output a voltage-stabilized power supply (VCC). A load sudden-change protection circuit includes an overvoltage protection component and an under-voltage protection component that are each respectively connected to the voltage-stabilized power supply and a load. The overvoltage protection component turns on the load when the voltage of the voltage-stabilized power supply is higher than a first preset voltage due to sudden turn-off of the load. The under-voltage protection component turns off the load when the voltage of the voltage-stabilized power supply is lower than a second preset voltage due to sudden turn-on of the load.
