Abstract:
1. A predictive warning system for incubator gas sensor failure, comprising: at least one gas sensor disposed in an incubator housing; an embedded controller for analyzing the at least one gas sensor for failure by adjusting a percentage gas sensor lifetime hours measurement for the at least one gas sensor; means for normalizing the adjusted percentage gas sensor lifetime hours measurement of the at least one gas sensor; means for holding a gas concentration and a gas sensor temperature constant over a previous hour prior to performing the normalizing; means for calculating a measurement for the at least one gas sensor of a percentage lifetime hours used for comparison with a respective maximum percentage hours for the at least one gas sensor, wherein the adjusted percentage gas sensor lifetime hours measurement of the at least one gas sensor is normalized, in said embedded controller, to an hour count stored as a percentage measurement of lifetime hours used at a temperature of 20 degrees Celsius; and an interface display for predicting failure of the at least one gas sensor to a user.
