- at least one microprocessor;
a micro-ingredient subsystem;
a control logic subsystem for converting control signals provided by the at least one microprocessor into a form usable by the micro-ingredient subsystem, wherein the control logic subsystem configured to;
define a PWM drive signal having a defined voltage potential, wherein the PWM drive signal has a plurality of “
on”
portions and a plurality of “
off”
portions that define a first duty cycle for regulating, at least in part, a first flow rate of the at least one pump assembly; and
pulse width modulate at least a portion of the “
on”
portions of the PWM drive signal to define a second duty cycle for the at least a portion of the “
on”
portions of the PWM drive signal, wherein the second duty cycle regulates, at least in part, a percentage of the defined voltage potential applied to the at least one pump assembly; and

Abstract
A method and computer program product for defining a PWM drive signal having a defined voltage potential. The PWM drive signal has a plurality of “on” portions and a plurality of “off” portions that define a first duty cycle for regulating, at least in part, a flow rate of a pump assembly. At least a portion of the “on” portions of the PWM drive signal are pulse width modulated to define a second duty cycle for the at least a portion of the “on” portions of the PWM drive signal. The second duty cycle regulates, at least in part, the percentage of the defined voltage potential applied to the pump assembly.
