Described embodiments generate tasks corresponding to each packet received by a network processor. According to an embodiment, the display driving chip comprises, inputoutput pads each electrically connected to a lower interconnection on an active area, the IO pads forming a perimeter on an inner peripheral surface of the active area, and dummy pads formed on the active area within the perimeter of IO pads. The entire frame is made of high strength sheet steel. The collector modules may be rotatable so as to reflect incident sunlight onto a target receiver mounted on a tower, and substantially all of the collector modules for a given tower may be located in a rectangular area that extends polewards from the tower by a distance of approximately three times the height h of the target receiver and that is approximately h wide. The system generates an influence ranking of site’s that influence a particular conversation.
