Techniques described herein enable parents to establish a child-protective \u201ckids zone\u201d on a DVR. Embodiments include methods for taking multiple color data readings with a series of sensing elements in one collecting location during a single exposure, associating the collecting location with a pixel, and calculating a color value for the pixel based on the multiple color data readings. A height-adjustable, downwardly foldable ironing board is secured to two of the grooved vertical posts. This may be accomplished without the use of external electric power, and the energy producing and heat transferring components of the water heater are optimally balanced, resulting in a sustained energy level that minimizes heat loss, prevents unwanted increases in water temperature, and enables the use of a damper without external electrical power. Therefore, an external apparatus can easily determine whether or not the semiconductor memory is an unauthorized copy by referring to the status.
