Embodiments of the invention are directed toward a novel pressurized vapor cycle for distilling liquids. The system includes a component to determine a foreground value and opacity value for each pixel on the set wherein \u03b1 is determined via a subpixel edge-offset to facilitate a separation the foreground region from background portions of the image. The predetermined requirement is, for example, that a movement speed is equal to or more than a predetermined threshold value, or that an event where a difference in angle between a current movement direction and an immediately preceding movement direction is equal to or more than a predetermined value has been detected a predetermined number of times or more within a given length of time. A system and a method for transmitting radio signals in a broadband structure including a first network, said first network operating on air as a first medium.
