Methods and systems are provided for assigning objects to processing units. The device and member are coupled at their distal ends by a corresponding set of opposing curves. As a result, the user does not have to set the photographing direction to capture a panoramic image using a mobile terminal. In a third novel aspect, transceiving mechanisms over multiple component carriers in DLUL overlapped subframes are proposed. In addition, the front cover is provided with a case cover for preventing the button keys from popping out therefrom. The control device may be electrically connected both to the first drive and to the second drive for the purpose of energization.
