    Analysis of breath sounds (auscultation) is an important part of the diagnosis of pulmonary diseases. An automatic breathsounds classification scheme is suggested. Types of normal and abnormal breath sounds are classified, with the goal of providing the physician with a diagnostic assist device. The classification is performed in two levels. The first level is based on the linear prediction coeffl... View full abstract»

    A new statistical method for heart-sound processing was developed and tested on normal subjects and on patients suffering from various cardiac pathologies. The method is effective in decreasing noise and in separating heart sounds from murmurs, as well as in deriving new physiological parameters. The theory is based on the assumption that heart sounds can be classified into deterministic and nonde... View full abstract»

    Surface EMG was recorded from the biceps with fixed muscle length at S0 percent maximal voluntary contraction. The signal bandpass was 10-230 Hz where most of the surface EMG energy is located. The signal sampled at 500 Hz was found to have a changing spectrum. Stationary segments of 500 ms were subject to linear prediction mathematics to model the system. View full abstract»

    This paper presents a new method of solution for the inverse problem in electrocardiography using the finite element procedure. It is an application of the authors' earlier work which derived a solution method by means of an integral equation under a generalized configuration of geometry and conductivity of the torso. Based on prior geometry information, the human torso region is discretized into ... View full abstract»

    This communication introduces the airflow perturbation device (APD) as a means for measuring airways resistance in humans and animals The APD uses a rotating screen to perturb airflow during spontaneous breathing. The resultant mouth pressure perturbation amplitudes are divided by flow rate perturbation amplitudes to give airways resistance. Data shown for both humans and swine demonstrate values ...

    The quantitative capability of pulsed Doppler ultrasound in clinical practice is limited by the effects of frequency-dependent attenuation of ultrasound in tissue, as well as several other spectral-broadening mechanisms which distort the Doppler spectrum of an ultrasonic echo. In this communication, we present results of in vitro experiments which demonstrate the magnitude of the errors expected i... View full abstract»
