  • Publication number: 20100205342
    Abstract: In a function expansion method for an electronic product and a device thereof, the device includes a circuit board, a microprocessor unit and a storage unit. The circuit board includes an expansion socket, and the expansion socket includes a plurality of plugholes. The microprocessor unit is installed onto the circuit board and electrically coupled to the each plughole. The storage unit is installed onto the circuit board and electrically coupled to the microprocessor unit. The microprocessor unit scans a predetermined plughole group installed on the expansion socket to determine whether or not a functional device is plugged, and then determines what type of functional device is plugged into the plughole group, and finally reads a driver program of the functional device from storage unit, and the functional device is installed or driven.

  • Publication number: 20100161163
    Abstract: An auxiliary apparatus of wheeled luggage, capable of being pulled, includes an electricity-generating unit, a charging unit, a storage unit, a control unit, a driving unit, an actuating unit, a transmission unit and a sensing unit. When the luggage is being pulled, the wheel set of the luggage generates power to bring along the electricity-generating unit to generate electricity. The output electricity is in turn charging the storage unit via the charging unit. In the meantime, the signal sensed by the sensing unit is judged by the control unit. If it is needed to generate an auxiliary power source, then a control signal is output from the control unit to drive the driving unit, making the actuating unit bring along the transmission unit, which in turn brings along the wheel set by using the generated auxiliary electricity. Therefore, the user can pull the wheeled luggage to walk with an easy effort.
