Abstract: An online pairing method and a computer-readable storage medium are proposed. The online pairing method may be applied to a signal source device and a display device. The signal source device may output a display signal to the display device for display. The method may include dual-channel connection, transmitter sending identity identification information, receiver entering pairing mode, transmitter entering pairing mode, receiver sending online information, and communication connection. Various embodiments can make online pairing and its usage easy, and can improve user experience.

Abstract: A joystick module includes a casing, a movable component, a circuit board, a base, a swing arm, a joystick and a sensor. The movable component is disposed inside or outside the casing. The base is disposed within the casing. The swing arm is disposed within the casing, pivotally connected to the base and connected to the movable component for driving the movable component to move. The joystick is connected to the swing arm for driving the swing arm to move. The sensor is disposed on the circuit board and opposite to the movable component, and configured to sense a plurality of received signals from the movable component. The received signals are different with the movement of the movable component.

Abstract: A media pick system includes a pick-up rack, a pick-up roller, a separate roller, a swing gear arm, a swing gear lever, and a part of action. While the separate roller and the swing gear arm are driven to rotate, the swing gear lever would be driven to rotate. Therefore, while the torque generated on the pick-up rack by the part of action so that the pick-up rack could be lifted up or pushed down to pick up the media.
