A plurality of high capacitance capacitors are coupled to supply or accept large currents. An alert help data file is periodically downloaded at a client computer. A saltwater intrusion barrier subsystem in fluid communication with the retention reservoir is positioned at an interface of the fresh water body and the saltwater body. The chemical composition of the plasma is calculated. A battery or other power source may be provided as well to allow the motorized camera to be portable and operate independent of external power sources or other external devices. In a driving IC 100, bumps 10, 12, 14, 16, 18, 22, 24, 26 and 28 are arrayed in a first row 110 and bumps 11, 13, 15, 17, 21, 23, 25, 27 are arrayed in a second row 120, wherein the respective bumps are disposed so that the shortest distances between forward ends of the respective bumps and a side along the array, become larger gradually from the center outward in the array.
