1. A method of detecting moisture on a glass substrate, the method comprising:

  • providing a parameterized model (M) for a possible moisture-related disturbance;

    providing background information (I) concerning the model;

    calculating a prior probability of M given I, P(M|I);

    collecting data from at least one sensor (D) connected to the substrate;

    computing a probability of the model given D and I, P(M|D,I);

    repeating the computing of P(M|D,I) as additional data is collected; and

    accepting the model if P(M|D,I) meets and/or exceeds a predetermined threshold,wherein the glass substrate is a part of a vehicle window, building window, or merchandiser window; and

    wherein acceptance of the model triggers an action to be taken relative to the glass substrate, the action being selected from the group consisting of;

    (i) causing a wiper to remove moisture from a vehicle window, (ii) heating the glass substrate, and (iii) defrosting the glass substrate.
