Classification: CPC H  G | IPC G  H

Claim 7:
8. A method comprising:
identifying historical sensor data associated with wafer or display manufacturing equipment; and
identifying historical windows associated with the historical sensor data, wherein:
corresponding data points of the historical sensor data in a normal operation window of the historical windows are substantially stable along a first health index value;
the corresponding data points of the historical sensor data in a pre-failure window of the historical windows increase from the first health index value to a peak at a second health index value; and
the historical sensor data and the historical windows are to be used to determine, based on current sensor data, whether one or more components are within the pre-failure window to cause performance of a corrective action associated with the one or more components.
