An irrigation control system and method for controlling irrigation based on weather data. The first logic block is configured to operate in at least one of a first functional mode and a first scan mode. Metrology data from the processed semiconductor wafer is acquired. The free form reflector output module is configured for generating a free form reflector according to the optimum free form surface and outputting the free form reflector, in the form of a computer-aided design drawing, to a display andor a printer. The result is a range of write times that do not alter the binary Read Data signal. The MMS subsystem may be part of a wireless mobile communication device.
