Heating control arrangement for an electronic smoking article and associated system and method

A heating-control apparatus for an aerosol precursor arrangement of an electronic smoking article, comprising:

• a heating device arranged to heat the aerosol precursor arrangement;
• a power source in communication with the heating device;
• and
• a controller in communication with the heating device and the power source, the controller having a processor configured to at least:
• direct the power source to provide power to turn the heating device on and commensurately initiate a heating time period;
• and at a periodic rate until expiration of the beating time period,
• determine a moving window of measurements of instantaneous actual power directed to the heating device, each measurement of the window of measurements being determined as a product of a voltage at the heating device and a current through the heating device;
• calculate a simple moving average power directed to the heating device based on the moving window of measurements of instantaneous actual power;
• compare the simple moving average power to a selected power set point associated with the power source;
• and
• adjust the power directed from the power source to turn the heating device off or on at the periodic rate at each instance in which the simple moving average power is respectively above or below the selected power set point.

At least one non-transitory computer readable storage medium having computer program code stored thereon for controlling heating of an aerosol precursor arrangement of an electronic smoking article, the computer program code comprising:

• program code for directing power from a power source to turn a heating device on to heat the aerosol precursor arrangement and commensurately initiating a heating time period;
• and at a periodic rate until expiration of the heating time period,
• program code for determining a moving window of measurements of instantaneous actual power directed to the heating device, each measurement of the window of measurements being determined as a product of a voltage at the heating device and a current through the heating device;
• program code for calculating a simple moving average power directed to the heating device based on the moving window of measurements of instantaneous actual power;
• program code for comparing the simple moving average power to a selected power set point associated with the power source;
• and
• program code for adjusting the power directed from the power source to turn the heating device off or on at the periodic rate at each instance in which the simple moving average power is respectively above or below the selected power set point.
