Abstract: A method is provided for a device comprising at least one sensor providing sensor data. The method includes receiving, by a computer coupled to the device, the sensor data, providing the sensor data to at least one rule detector, evaluating, by the at least one rule detector, instances of sensor data triggered by the at least one rule detector, and determining, by the computer, that a sampling interval has ended, and in response calculating a data quality index based on the instances of triggered sensor data.

Abstract: A method is provided for a device not having an available history of either failures or degraded performance. The method includes establishing, by a computer coupled to the device, an initial baseline of sensor data from the device, receiving new sensor data after establishing the initial baseline, creating an updated baseline based on the new sensor data, evaluating, by the computer, the new sensor data compared to the updated baseline based on a plurality of different time scales, and determining whether the device is indicating an increased probability of failure or degraded performance based on the evaluated sensor data.
