Claim 26:
27. A method of predicting failure of an applicator of a hot melt liquid dispensing system, the applicator configured to dispense hot melt liquid and the hot melt liquid dispensing system further having a hot melt liquid heater associated with the applicator, the method comprising:
providing a plurality of applicator parameter values of a first operating parameter of the applicator, each applicator parameter value of the plurality of applicator parameter values being temporally associated with a time interval of a first block of time;
determining a first subset of applicator parameter values of the plurality of applicator parameter values, each applicator parameter value of the first subset of applicator parameter values indicating no dispensing activity of the applicator for a temporally associated time interval of the first block of time;
determining a second subset of applicator parameter values of the plurality of applicator parameter values, each applicator parameter value of the second subset of applicator parameter values indicating dispensing activity of the applicator for a temporally associated time interval of the first block of time; and
based on the first subset of applicator parameter values and the second subset of applicator parameter values, determining a predicted time of failure of the applicator.
