    We review ultrasonic measurement of fluid flow with emphasis on ultrasonic pneumotachometers (UPTM's). For PTM's we discuss specifications such as dynamic range, resistance, and frequency response. We review fluid flow principles and point out the problems of nonultrasonic PTM's For UPTM's we describe transducer construction, attenuation versus frequency, reflection at interfaces, and acoustic fie...

    This paper presents a critical review of the most relevant experimental data obtained from electrophysiological studies of the Pacinian corpuscles. A mathematical model of the mechanoreceptor is proposed and utilized to clarify the relationships between the variables involved in the mechano-to-neural transduction. This model accounts for the two main components of the corpuscle: the lamellated str... View full abstract»

  • Dynamics and Limitations of Blood/Muscle Interface Detection Using Doppler Power Returns

    A new method that relies on backscattered Doppler power from red cells to locate and track blood/muscle interfaces is described. It allows current pulsed Doppler flowmeter systems to yield continuous information on internal vessel diameter and to evenly distribute range gates within the lumen. A smal signal model is fommulated that describes this feedback approach and indicates the relationships b... View full abstract»

  • Automatic Continuous-Time Blood Pressure Control in Dogs by Means of Hypotensive Drug Injection

    An automated drug administration system is proposed to control the decrease in the mean arterial blood pressure of dogs. It is accomplished by identifying a model for the open loop system consisting of a syringe pump and a dog. A linear feedback controller is then determined by solving an inverse optimum control problem. The chosen controller is optimal relative to a quadratic critexion. The contr... View full abstract»

  • Statistical Modeling of Fetal Heart Rate Variability

    The random variability of fetal heart rate (FHR) is of practical importance in obstetric management. The variability is not white, however, and cannot be adequately described by its variance alone. We have modeled FHR variability as the scalar output of a multivariate, nonlinear stochastic process. An adaptation of the Kalman filter algorithm is used as part of an approximate maximum likelihood es... View full abstract»

    Pneumotachometers (PTM's) measure the instantaneous rate of volume flow of respired gas. Currently existing PTM's suffer from a number of limitations. Ultrasonic PTM's are superior in a number of ways to these PTM's, but have not yet achieved acceptance due to instabilities and inaccuracy. We investigated a new design which used cylindrical shell transducers to generate ultrasound and measured pha... View full abstract»

  • Evaluation of a Laser Doppler Flowmeter for Measurement of Tissue Blood Flow

    An instrument for measurement of tissue blood flow based on the laser Doppler principle was evaluated using a fluid model. A unique and linear relationship between flowmeter response and flux of red cells was demonstrated with red cell velocities and volume fractions within the normal physiological range of the microcirculatory network of the skin. Different degrees of oxygenation proved to influe... View full abstract»

  • On the Role of Dynamic Models in Quantitative Posturography

    Conventional approaches to posturography typically make use of force-plate instrumentation to measure the movement of the center of pressure of ground reaction forces during quiet standing. This paper shows that such information can be obtained indirectly by using a four-mass inverted pendulum dynamic model for the body as the basis for processing motion data transmitted directly from television c...

  • Contaminated Renewal Processes and the Serial Correlogram

    Publication Year: 1980 , Page(s): 610 - 613

    We derive the mean and variance of the sample serial correlation coefficients of a finite portion of a renewal process, the realization of which is contaminated by the addition or deletion of one point. This enables us to determine the asymptotic power of a test that the contaminated process is significantly different from a renewal process. In contrast to the signficant changes in serial correlat... View full abstract»

  • Theoretical Validation of the Thermal Dilution Method for Cardiac Output Determination

    The basic formula of the thermal dilution method for the measurement of cardiac output is proven for pulsatile flow, assuming constant stroke rate, equal stroke volumes, and ideal ventricular mixing. Firstly, for an ideal thermistor of negligible response time which presents the temperature of the blood in the pulmonary artery as a step function; then it is shown that the area under the curve of t...
