A mobile device and a method for sharing a hardware device thereof are provided. The connecting unit separably connects the flat wiper blade to a wiper arm having one of the following: a first coupling element including a top plate and a pair of side plates having a concave portion at a rear end; a second coupling element including a top plate and a pair of side plates; and a third coupling element including a side pin and a clip arm. The anchor further comprises an inner tube disposed inside of the housing along an intermediate portion between the extended portion and the shorted portion. The device also includes a coupling configured to engage the screw and operable to rotate the screw when rotational force is applied to the coupling. A first terminal of the selection transistor is connected to a first terminal of the PCM storage element, and the control terminal of the selection transistor is connected to a respective word-selection line. The second cooling circuit provides a parallel cooling path that enhances the cooling capacity of the cooling system when the engine temperature exceeds the threshold.
