Power lighting control methods and systems for solid state lighting are disclosed. According to the present invention, using a genus-specific primer set that can detect four Plasmodium parasites that infect humans at a time, and the primer sets each specific to each of four species of Plasmodium parasites, the presence or absence of infection with these parasites can be detectedidentified easily and rapidly. A further feature of the invention is the quick removal and securement of the vibratory plate screen. The computer system determines an estimated write count and identifies one or more allocated blocks whose write counts are within a specified number of write operations of the estimated write count. The voltage generator generates a third voltage according to the first voltage, wherein the third voltage is greater than the first voltage.
