Abstract
One embodiment of the present patent application is a method of monitoring a rotating part. The method includes providing a shaft, a sensor, a processor, an energy storage device, and a transmitter. The method further includes mounting the sensor directly on the shaft and mounting said processor, said energy storage device, and said transmitter to rotate with said shaft. The method further includes rotating the shaft and waking the processor for a period of time and drawing energy to the processor from the energy storage device to provide the processor in an active mode during the period of time. The method also includes sampling the sensor during the period of time. It also includes returning the processor to sleep mode. The method also includes transmitting data derived from the sensor.
