A multi-purpose folding tool including a pair of folding scissors, in which a scissors blade is movable about a pivot shaft, between a stowed position and a deployed position. A request for content is received from a user. Further, the system includes a video receiving system for receiving and seamlessly combining the first and second video sections of different resolutions to form an output video image on a display device, and a control unit for sending one or more video control parameters to the video transmission system to control capturing, transmitting and processing of the video images. After being compared with the reference voltage, the output voltage is output from the reference voltage generation and comparison unit to the drive unit and the M drive unit candidate circuits. The photoelectric conversion layer and the conductive substrate form a working electrode.
