      abstract = {A method and apparatus for monitoring and responding to  conditions of an industrial process. Industrial process  signals, such as repetitive manufacturing, testing and  operational machine signals, are generated by a system.  Sensor signals characteristic of the process are generated  over a time length and compared to reference signals over  the time length. The industrial signals are adjusted over  the time length relative to the reference signals, the  phase shift of the industrial signals is optimized to the  reference signals and the resulting signals output for  analysis by systems such as SPRT.},
