Abstract: Methods that identify local motions in point cloud data that are generated by one or more rounds of LIDAR scans are disclosed. The point cloud data describes an environment with points with each point having a scanned time and scanned coordinates. From the point cloud data, a subset of points is selected. A surface is reconstructed at a common reference time using the subset of points. The reconstructed surface includes points that are moved from the scanned coordinates of the points in the subset. The moved points are derived from a projected movement under a projected motion parameter in duration between the scanned time and the common reference time. The surface quality of the reconstructed surface is determined. If the surface has a high quality, the projected motion parameter is determined to be the final motion parameter that is used as an indication whether an object is moving.

Abstract: A surge current suppression circuit includes a switch, a bypass resistor, a detection resistor, and a comparator. The switch is coupled to a first end of an energy storage capacitor in series, wherein a second end of the energy storage capacitor is coupled to a load and receives an input power source. The bypass resistor is coupled to the switch in parallel. The detection resistor is coupled to the switch in series to generate a detection voltage according to a capacitor current flowing through the energy storage capacitor. The comparator compares the detection voltage with a reference voltage to generate a control signal. When the detection voltage is greater than the reference voltage, the control signal controls the switch to be turned off. When the detection voltage is less than the reference voltage, the control signal controls the main switch to be turned on.
