Abstract: The present application provides a system for unmanned aerial vehicle (UAV) parachute landing. An exemplary system includes a detector configured to detect at least one of a flight speed, a wind speed, a wind direction, a position, a height, and a voltage of a UAV. The system also includes a memory storing instructions and a processor configured to execute the instructions to cause the system to: determine whether to open a parachute of the UAV in accordance with a criterion, responsive to the determination to open the parachute of the UAV, stop a motor of the UAV that spins a propeller of the UAV, and open the parachute of the UAV after stopping the motor of the UAV for a first period.

Abstract: A method includes forming a first package component, which formation process includes forming a first plurality of openings in a first dielectric layer, depositing a first metallic material into the first plurality of openings, performing a planarization process on the first metallic material and the first dielectric layer to form a plurality of metal pads in the first dielectric layer, and selectively depositing a second metallic material on the plurality of metal pads to form a plurality of bond pads. The first plurality of bond pads comprise the plurality of metal pads and corresponding parts of the second metallic material. The first package component is bonded to a second package component.

Abstract: A method for generating a three-dimensional image includes capturing a set of color images of an object, generating a first point cloud according to at least the set of color images, generating a second point cloud by performing a filtering operation to the first point cloud according to the set of color images, selectively performing a pairing operation using the second point cloud and a target point cloud to generate pose information, and combining the first point cloud and the target point cloud according to the pose information to update the target point cloud to generate the three-dimensional image of the object. The set of color images is related to color information of the object. The relativity of the second point cloud and the rigid surface is higher than the relativity of the second point cloud and the non-rigid surface.
