  • Sensor service prediction
    Patent number: 11221616
    Abstract: A sensor service prediction system and method are provided for a sensor. The system monitors sensor operations of the sensor, and provides a calendar age odometer which increments a calendar age of the sensor by a first time interval as the sensor operates. The system further provides an accelerated age odometer which increments an accelerated age of the sensor by a second time interval according to the increment of the calendar age and a sensor temperature or other measurable environmental condition associated therewith. The system obtains a value of a sensor property at different calendar ages or accelerated ages of the sensor over time, and predicts and outputs when the sensor property of the sensor is anticipated to reach a sensor property threshold based on the values of the sensor property in relations to the accelerated age.
