Claim 0:
1. A method for operating non-stationarily operating machinery, comprising:
acquiring at least a first non-stationary signal generated by at least one machine operating in a non-stationary manner during at least one operational time frame;
acquiring at least a second non-stationary signal different from said first non-stationary signal and generated by said at least one machine during said at least one operational time frame;
applying a wavelet transform to both of said at least first and second different non-stationary signals;
generating a mask of said wavelet transform of one of said first and second non-stationary signals;
multiplying said mask of said wavelet transform of said one of said first and second non-stationary signals by said wavelet transform of the other one of said first and second non-stationary signals;
extracting at least one feature of at least one of said first and second non-stationary signals based on said multiplying;
analyzing said at least one feature to ascertain a condition of said at least one machine; and
performing at least one of a repair operation, maintenance operation and modification of operating parameters of said at least one machine based on said condition.
