    To identify characteristics of a sensory feedback path of a posture control system without external disturbances, the maximum likelihood identification method was applied to data of an antero-posterior sway during quiet stance. A subject stood on a force plate and the sway angle of a body (input) was measured by a position sensor camera and the ankle joint moment (output) was measured by the force... View full abstract»

    We present an adaptive filtering (AF) technique for rapid processing of evoked potentials (EP). The AF algorithm minimizes the mean-square error (MSE) between successive ensembles. We demonstrate theoretically that the filter output converges to the least square estimate of the underlying signal. Computer simulations with known signal and added noise show that AF produces lower MSE than ensemble a... View full abstract»

    This paper discusses the design and performance of an optimum linear multielectrode filter for estimating the evoked potential contained in a single scalp-recorded brain response to a visual stimulus. The filter is derived under the criterion of minimum mean-square error and is time varying to allow for the nonstationarity of the brain response. Single-and two-channel filters are designed for simu... View full abstract»

  • A New Quantitative Indicator of Visual Fatigue

    Ocular-motor correlates of visual fatigue have remained elusive. Performance of ocular-motor tracking with a wide-band white noise input and the response of the dual-mode, smooth pursuit-saccadic eye movement system as output was used to test visual fatigue. A new visual fatigue indicator, VFI, was defined as the nonlinear remnant after subtracting an identified impulse response contribution to th... View full abstract»

    A noninvasive technique to monitor gastric electrical activity (GEA) and mechanical activity as an aid in assessing gastric motor function is presented. The GEA is measured with ordinary ECG electrodes located on the torso in the region above the stomach. The mechanical activity is recorded through an electrical impedance monitoring device. A study of a mathematical model of the electrically activ... View full abstract»

  • A Method for Quantitative Ultrasonic Backscatter Estimates in the Presence of Phase Distortion

    Publication Year: 1987, Page(s):37 - 42
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1997 KB)

    A method has been developed which can predict the backscatter properties of biological tissues from single amplitude spectra. Backscatter analysis from single spectra, based on the ratio of the Fourier transforms, is strongly influenced by the amplitude fluctuations, due to the inhomogeneous nature of biological tissues. The theoretical basis for the developed method is that the tissue produces an... View full abstract»

    A new theory describing the time-optimal control of saccadic eye movements is proposed based on Pontryagin's minimum principle and physiological considerations. The lateral and medial rectus muscle of each eye is assumed to be a parallel combination of an active state tension generator with a viscosity and elastic element, connected to a series elastic element. The eyeball is modeled as a sphere c... View full abstract»

    A theoretical and experimental study of the electrical resistance and the tip potential of open tip glass microelectrodes is presented. The main physico-chemica1l factors considered are the diffusion process of ions through the open tip, the ionic conduction in the bulk solutions, and the ionic conduction in the electrochemical double layers at the glass-electrolyte interface. In order to take int... View full abstract»

    Dielectric properties of the inflated and deflated fceline lung in vivo were investigated at frequencies from 10 kHz to 100 MHz. A computer-controlled network analyzer and a multiring capacitive sensor were employed. It was found that in the frequency range investigated, both the dielectric constant and the conductivity of the deflated lung were higher than those of the inflated one. The analysis ...

    In biomedical measurement systems, periodical disturbances like power line interferences often are a severe limitation. To evaluate small signals under such conditions, a new technique for the compensation of these disturbances has been developed. The operation principle is based on the measurement of some Fourier coefficients of the interference superimposed to the signal to be detected. These me... View full abstract»

    An open two-compartment model with a double site of drug absorption along the gastrointestinal tract is proposed to describe the pharmacokinetics of a new drug, veralipride. We give the analytical expression of the amount of drug, at any time, in the central compartment after successive oral solution administrations. By computer simulations, plasma level profiles are obtained, which show rebounds ... View full abstract»

    Recently in this TRANSACTIONS, a paper was published1, dealing with the electric potential problem in a circular conducting cylinder. The authors criticize the approach to the same problem as proposed by Okada in 1956. Obviously, an important motive for preparing the paper was the existence of contradictory results from different solution methods found in literature. We want to rehabilitate Okada'...

    This paper describes the design and initial evaluation of a device to transduce opening magnitude and movement of a valve used to separate the oral and nasal cavities. Miniature optoelectric components have been used to construct a device which meets a number of a priori design objectives. Usefulness of the device and direction for future research are discussed.
