A multitool for a firearm provides a frame adapted for storage within a handgrip cavity of a firearm and a plurality of tools rotatably mounted to the frame to move from within the frame to extending from the frame as a result of being rotatably mounted, wherein the plurality of tools are adapted for use to rehabilitate the firearm under predetermined malfunction conditions. The conductive film and a ground electrode on a TFT glass substrate are electrically connected with a conductive tape having adherence. The main controller stores the received status information in its memory and turns off a first relay to thereby interrupt the application of the AC voltage to a second power supply. Bit line pairs to be connected are alternately interchanged above and below, every one horizontally aligned sense amplifier.
