Abstract: The present application discloses a double-sided SiP packaging structure and a manufacturing method thereof, wherein the double-sided SiP packaging structure comprises a substrate, a first packaging structure arranged on the substrate, and a second packaging structure arranged below the substrate; the second packaging structure comprises a chip, interposer and a molding material; a conductive structure array is arranged on an upper surface of the interposer; the interposer is arranged below the substrate through the conductive structure array; a space region among a lower surface of the substrate, the chip and the interposer is filled with the molding material; a conductive bonding pad array is arranged on the lower surface of the interposer; and a groove is formed in a part of region between the conductive bonding pad and an edge contour of the interposer.

Abstract: The present disclosure relates to a control scheme for a functional motor vehicle used in a fixed site. The present disclosure provides a motor vehicle control system, including a motor vehicle and a remote-controller. The motor vehicle is provided with at least one vehicle control button. The remote-controller is provided with at least one remote-controller control button. The remote-controller and the motor vehicle can conduct a positioning and ranging. The motor vehicle control system has a first control mode and a second control mode, that is, respectively, an automatic walking mode for ensuring the safety and an easy push mode for ensuring the safety. The present disclosure can improve the vehicle control modes, allowing users to obtain better customer experience.

Abstract: A spiral-wound membrane structure includes a central pipe and a film roll. The central pipe comprises a filter body and end covers separately connected to two ends of the filter body. A passage is formed in the center of the filter body, and two ends of the filter body are embedded in the end covers to be bonded on and sealed by the end covers. The film roll includes a guide cloth, a membrane and a mesh. The film roll is wound on the central pipe. The central pipe is directly made of a filter material, can be used as a pre-filter or post-filter, and can be matched with the film roll in the spiral-wound membrane structure to form a highly-integrated two-in-one composite filter. The composite filter can be mounted on a water purifier.

Abstract: An environmental faucet includes a body, a valve seat, a valve core, an outlet elbow, a water-intake duct, an aerator, a locking cap and a handle. The valve seat and the valve core are mounted in the body. The outlet elbow is connected with a top end of the valve seat and has an outer pipe and an inner pipe, the outer pipe is made from metal, and the inner pipe is made from plastic. The water-intake duct is connected with a bottom end of the valve seat and has an outer pipe and an inner pipe, the outer pipe thereof is made from metal, and the inner pipe is made from plastic. As water entering the environmental faucet in a flow path sequentially through the water-intake duct and the outlet elbow does not flow through the metal portions, excessive heavy metal released in the water can be avoided.
