Claim 36:
37. The method of claim 33, further comprising:
providing a second plurality of applicator parameter values of the first operating parameter of the applicator, each applicator parameter value of the second plurality of applicator parameter values being temporally associated with a time interval of a second block of time;
providing a second plurality of heater parameter values of the second operating parameter of the hot melt liquid heater, each heater parameter value of the plurality of heater parameter values being associated with an applicator parameter value of the second plurality of applicator parameter values;
determining a third subset of applicator parameter values of the second plurality of applicator parameter values, each applicator parameter value of the third subset of applicator parameter values indicating no dispensing activity of the applicator for a temporally associated time interval of the second block of time;
determining a fourth subset of applicator parameter values of the second plurality of applicator parameter values, each applicator parameter value of the fourth subset of applicator parameter values indicating dispensing activity of the applicator for a temporally associated time interval of the second block of time;
determining a third subset of heater parameter values of the second plurality of heater parameter values, each heater parameter value of the third subset of heater parameter values being associated with an applicator parameter value of the third subset of applicator parameter values; and
determining a fourth subset of heater parameter values of the second plurality of heater parameter values, each heater parameter value of the fourth subset of heater parameter values being associated with an applicator parameter value of the fourth subset of applicator parameter values,
wherein the predicted time of failure of the applicator is further based on the third subset of heater parameter values and the fourth subset of heater parameter values.
