Moisture sensor and/or defogger with Bayesian improvements, and related methods

摘要

In certain example embodiments, moisture sensors, defoggers, etc., and/or related methods, are provided. More particularly, certain example embodiments relate to moisture sensors and/or defoggers that may be used in various applications such as, for example, refrigerator/freezer merchandisers, vehicle windows, building windows, etc. When condensation or moisture is detected, an appropriate action may be taken (e.g., actuating windshield wipers, turning on a defroster, triggering the heating of a merchandiser door or window, etc.). Bayesian approaches optionally may be implemented in certain example embodiments in an attempt to improve moisture detection accuracy. For instance, models of various types of disturbances may be developed and, based on live data and a priori information known about the model, a probability of the model being accurate is calculated. If a threshold value is met, the model may be considered a match and, optionally, a corresponding appropriate action may be taken.

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, I being known a priori; 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 or exceeds a predetermined threshold, and otherwise rejecting the model, wherein the glass substrate is a part of a vehicle window, building window, or merchandiser; 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.
