A method for production of a multi-layer carbon brush including at least two electrically-conducting functional layers made from carbon material and at least one insulation layer made from an electrically-insulating material, running between consecutive functional layers. The system, method and apparatus uses a motion detection means in conjunction with an image processor to alter the native image to one without image tearing or other visual artifacts. This makes it possible for the CPU to automatically recognize the server immediately after the network cable is connected to the cable connecting unit without requiring a user to spend time and labor for the server recognition.
