A fast algorithm for detecting contractions in uterine electromyography

Discusses a method of higher-order zero crossings, which was found to be an effective tool for signal analysis. This method mirrors the spectral characteristics of certain Gaussian and non-Gaussian processes. The authors use this method to discriminate between contraction segments interspersed in a uterine EMG recorded from the abdominal surface. They also describe a schematic circuit that can be implemented for fast on-line detection of contraction segments.
