Abstract: A device for generating a limited-time 2D barcode symbol is provided. In one embodiment, the device includes a casing; a display on the casing for showing a barcode symbol; a MCU in the casing and electrically connected to the display, the MCU being capable of generating a limited-time 2D barcode symbol and sending same to the display for display, or deleting the 2D barcode symbol after a time limit of the 2D barcode symbol has expired; and a power supply in the casing and electrically connected to both the MCU and the display.

Abstract: An electronic device includes a chassis defining an opening. A motherboard is received in the chassis and a data storage device comprising a circuit board with storage unit can be directly coupled to the motherboard. The data storage device is mounted to the chassis through the opening but is detachable.

Abstract: A carrier includes a frame defining a first space configured to accommodate a first type of hard disk drive, and an adjusting mechanism rotatably coupled to the frame. The adjusting mechanism is transitionable between: (i) a first configuration in which the adjusting mechanism is located outside the first space defined by the frame, and (ii) a second configuration in which the adjusting mechanism is located inside the first space, the adjusting mechanism and the frame cooperatively define a second space configured to accommodate a second type of hard disk drive different from the first type of hard disk drive.

Abstract: A manufacturing method of composite material includes following steps: shaping a stainless steel plate to a stainless structural component; putting the stainless structural component in a female mold; putting a fiber material over a surface of the stainless structural component away from the female mold; and pressing a male mold towards the female mold to make the fiber material attached to the stainless structural component. The present invention is able to make different materials attached to each other to form a composite material in a simple and efficient manufacturing process, and the composite material is light; thin and has advantages of high rigidity and high strength.

Abstract: A manufacturing method of metal-glass composite material is disclosed. The manufacturing method of the metal-glass composite material includes following steps: coating one surface of a glass plate with an adhesive material; placing a metal plate and the glass plate in a press mold, wherein the surface of the glass plate with the adhesive material corresponds to the metal plate; and pressing the glass plate and the metal plate by the hot-press mold to make them attach to each other. A manufacturing system of the metal-glass composite material is also provided.
