Provided are novel interconnecting strips for electrically connecting building integrable photovoltaic modules in a photovoltaic array. The post-processing device is provided with a transformation unit that transforms a voltage of power supplied from a main power supply unit inside the main body device to a voltage required for driving of the post-processing device. First and second electrodes may contact top center and lower center regions of the forehead, respectively, third and fourth electrodes may contact front right and front left regions of the forehead, respectively, fifth and sixth electrodes may contact right side and left side regions of the forehead, respectively, and electrodes included within the securing devices may contact the ear regions. Dipoles are oriented parallel to the coaxial line axis, with opposite \u201chot\u201d elements oppositely oriented. , and layer of polyurethane foam located beneath layer of flexible foam, the layer of polyurethane foam having hardness of at least about 50 N.
