A system for use in monitoring operation of a rotating device includes at least one first sensor that senses a position of a first component coupled to the rotating device, and at least one second sensor that senses a position of a second component coupled to the rotating device. The image capture device is configured for capturing images, converting the images into a first electronic signal, and transmitting the first electronic signal through a first type transmission interface. Failure analysis to date has focused on physical, randomly distributed defects of devices rather than systematic problems caused by the mask manufacturing or mask application process.
