    Abstract: A fault diagnostic apparatus may include an upper case with a bottom having an opening, a lower case coupled to the bottom of the upper case, and a printed circuit board (PCB) substrate module including a substrate supported on an inner side of the upper case or the lower case, and a microphone disposed in the substrate adjacent to the vibration plate to generate a sensing signal of an acoustic wave by the vibration generated from the vibration plate. The lower case may have a vibration plate formed toward the upper case on a lower surface and be configured to vibrate itself in response to an external vibration.

    Abstract: A variable pitch pulley includes a rotary shaft, a fixed sheave fixed to the rotary shaft, and a moving sheave forming a belt groove with the fixed sheave. The moving sheave includes an inner sheave and an outer sheave radially stacked on the inner sheave. The pitch pulley further includes a moving sheave-positing unit determining relative positions of the inner and outer sheaves. The inner and outer sheaves are simultaneously moved in an axial direction of the rotary shaft in a first moving mode, and only the outer sheave is moved in the axial direction in a second moving mode.

    Abstract: Disclosed is a method for supporting a real-time lecture on any subject via telephone, in which if an instructor expresses, via a terminal, an intention to currently provide a lecture to a list of lecture available subjects that have been previously registered: a process of measuring an expected quality of media traffic between anInternet telephone server and an instructor terminal and quantifying and storing the same is added, and if a student who wants a real-time lecture on any subject chooses an instructor from a list of currently lecture available instructors for the subject in accordance with an expected telephone call quality or his/her preferences, and requests a real-time lecture with simple additional information such as a subject or a lecture time, the instructor accepts the lecture after confirming the additional information; before performing an actual telephone connection, an expected quality of the media traffic between the instructor terminal and a student terminal is measured, and when the expected quality is below a predetermined reference value, the instructor and the student are notified, and when the expected quality meets the reference value or the instructor and the student agree, it is supported to connect a telephone for a real-time lecture between the instructor and the student; and in the case of an ordinary telephone, only an actual telephone connection is supported.
