SENSOR RECORDING ANALYSIS APPARATUS AND METHOD

Abstract:

Methods and apparatus to analyze sensor recordings are disclosed. An example apparatus includes a sensor to record a plurality of recordings and a memory. The example apparatus also includes a processor to convert one or more of the plurality of recordings to corresponding spectral representations where the at least two recordings are separated by a time gap, calculate a spectral average based, at least in part, on the spectral representations, store the spectral average to the memory, and generate a data packet based, at least in part, on the spectral average. The example apparatus also includes a transceiver to transmit the data packet to another device to compare the spectral average to a baseline spectral average to determine a system condition.
