When the control module 38 receives the second comparison signal, the control module 38 may control the host 25 so that the host 25 performs the second operation (S88).

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
