An exemplary system and method are disclosed for providing a combined video stream with geospatial information. Multiple peripheral circuit elements of one type are placed side by side in a certain direction, aligned in that direction with one or more memory cell arrays, and are coupled in parallel to the associated circuits of those memory cell arrays. The etching process does not attack the transistor structure and forms an opening bounded by upper surfaces that extend downwardly from the substrate surface and are substantially vertical, and lower surfaces that bulge outwardly from the upper vertical sections and undercut the transistor structure. The charging controller controls the connector so that the portable battery is charged to a desired value of voltage that corresponds to the monitored voltage in the charging table.
