    The uterine electromyogram (EMG) has been proven to be an efficient tool for pregnancy and parturition monitoring. Temporal and spectral characteristics of this signal, recorded by means of external electrodes, make it possible to discriminate between efficient and inefficient contractions in terms of electrical command capability. As it is possible to record the uterine electrical activity as ear... View full abstract»

    Acoustic signals are often characterized by pitch, timbre, loudness, forms of modulation, and onset/offset instants. These descriptors of sound quality have a close relationship to the instantaneous spectral properties of the sound waves. The auditory system has developed elegant mechanisms to extract and represent this spectro-temporal information through noise-robust perceptual features. After d... View full abstract»

    A new mutual wavelet packets scheme is proposed for subband adaptive filtering. Its relation to the existing literature on the subject is outlined. The proposed scheme performs a decomposition of the two signals used in the adaptation process onto the same optimal basis. That basis is chosen so that it favors the adaptation performance. A new criterion, based on a functional of the two signals, is... View full abstract»

    The purpose of this study was to investigate the feasibility of using a wavelet transforms (WT) as a preprocessor for an artificial neural network (ANN) based EEG spike detection system. The study aimed at decreasing the input size to the ANN detector, without decreasing the information content of the signal and degrading the detection performance. Since routine clinical EEG requires recordings fr... View full abstract»

    Many of the most powerful and effective algorithms in signal processing start with the assumption of stationarity. In addition, the deterministic portion of the signal is often assumed to be composed of complex exponentials that are the solutions to linear time-invariant (LTI) differential equations. These assumptions are often valid enough to yield good results when the signals and systems involv... View full abstract»

    Spontaneous breathing movements in the fetus tend to occur intermittently, and do not become continuous until after birth. In both the primate and the ovine species, breathing movements have been observed to have a high degree of variability in instantaneous breathing rates. In this study, ewes were surgically instrumented for chronic intrauterine recording of fetal diaphragmatic EMG. The matching... View full abstract»

    Quantitative phonocardiography has been limited by many factors: nonstandard nomenclature and recording techniques, complicated mechanoacoustic generation, propagation and coupling, and inherent heart sound nonstationarity. New nonstationary signal processing techniques provide a powerful tool for phonocardiography, particularly in regard to the first heart sound. Recent work supports the concept ...

    Can a patent owner sue a competitor who is about to bring out an infringing product? That was the question before the court in the recent case of Interdigital Technology Corp. v. OKI America Inc. and Qualcomm Inc. The case involved the burgeoning field of cellular telephones. Interdigital owned patents which it believed gave it control of all cellular telephones that would satisfy two of the indus... View full abstract»

    This study further demonstrates that the wavelet approach to the analysis and characterization of respiratory-related evoked potentials (RREPs) is a more efficient method than traditional ensemble averaging. Wavelet decomposition of the 200 trial ensemble averaged evoked responses results in smoothed signals at scale 4 with characteristics similar to those present in the ensemble averages, indicat...
