A computer system according to the present invention, comprises a light emitting diode indicating unit for indicating a power management system state such as an Advanced Power Management mode and an Advanced Configuration and Power Interface mode, and a microcomputer for controlling the indicate unit in response to the power management system state. After a pattern is printed on a substrate, an inkjet module is enabled to perform first transparent ink spraying on an entire pattern region with UV lights on, so as to form a first transparent color layer on the pattern, and then perform second transparent ink spraying on an entire region of the first transparent color layer with the UV lights off. The parameters are further tailored, typically by a master computer, to allow for the total contribution of side effects from electrical processing at each station, to optimise the quality of meat taken from the carcass. In one embodiment, the programmer is presented with numerical data pertaining to an improvement ratio associated with application of the source code optimization. The first end is disposed at a first radius from the longitudinal axis and spaced at a first distance from the metering disc. Reset circuitry cooperates with the reset switch to connect and disconnect the reset capacitor in a manner which provides for resetting the transformer and which allows a current having a non-zero average value to flow in the reset switch.
