    Attraction between a pair of rare earth-cobalt magnets is very useful for retention of dental prosthetic appliances. In these applications, the space available for embedding magnets is very narrow. Therefore, the magnets must have those optimum dimensions which cause the mximum attraction. The optimum dimensions are calculated for a rectangular or disk magnet pair utilizing the axial or radial att... View full abstract»

    A new Doppler frequency estimator operating in the discrete time domain is derived from an analysis of the Doppler signal statistics. It is shown that the estimator gives a nearly unbiased estimate of the mean frequency of the signal spectrum, regardless of the spectrum shape. The discrete time implementation gives the advantage that, under specified conditions, the range-velocity product of a pul... View full abstract»

  • A Low-Noise Low Input Impedance Amplifier for Magnetic Measurements of Nerve Action Currents

    We have developed a low-noise solid-state current-to-voltage amplifier to measure the magnetic fields produced by nerve action currents. The amplifier senses the EMF induced in a toroidal, ferrite-core pickup coil surrounding the nerve by the circumferential magnetic field associated with the axial nerve action currents which propagate past the toroid. In order to obtain low input voltage noise, t... View full abstract»

    The relation between the electric and magnetic fields of the heart outside the body is considered on the assumption that the primary bioelectric generators impressed membrane currents may be represented as geometrically curvilinear thread-like flows. An approach based substantially upon the multipole expansion of scalar potentials is developed for distinguishing between two parts of a measured tot... View full abstract»

    Red blood cells lyse when subjected repeatedly to osmotic swelling and shrinking. The number of osmotic cycles causing 50 percent of the cells to lyse increases exponentially as the magnitude of swelling decreases. An extrapolation of this relationship to the osmotic volume changes cells experience in vivo gives the survival halflife of red cells in circulation. View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (996 KB)

    A system is described which uses scattered laser light to study the kinetics of cellular suspensions. The scattered light is collected by optical fibers placed at 10├é┬░increments around the cuvette. With a novel normalization scheme all outputs are made proportional to the percentage changes relative to the values measured upon insertion of the sample. The system includes a noise level detector to ... View full abstract»

  • EEG Measurement During Electrical Stimulation

    When the EEG is recorded during electrical stimulation, large artifacts will appear in the EEG signal as a result of the stimulation pulses. The circuit presented suppresses these artifacts before the signal enters the amplifier. This way, saturation of the amplifier and filtering of the artifacts, which otherwise would disturb the EEG measurement, are prevented. View full abstract»

  • A Learning Filter for Removing Noise Interference

    We have developed a microcomputer-based filter that removes line induced electrical interference from biopotential signals by learning one period of the noise waveform and subtracting it from the signal. Since it uses a noise template, the filter can remove noise waveforms containing several harmonics of the 60 Hz line frequency. View full abstract»

    The correlation among three nerve cells may be plotted as a three-dimensional graph. On the graph's base all possible sequences of three spikes (one from each spike train) may be represented. The relative abundance of each possible sequence is plotted vertically above this base. The correlation may be estimated by dividing the base into triangular bins and counting the number of occurrences of a p... View full abstract»

    Pulsatile flow waveforms in the dog femoral artery and abdominal aorta were derived from measurements of pressure before and after a brief vessel occlusion. Derived flows compared favorably with directly measured flows in the abdominal aorta, less so in the femoral artery. Possible sources of deviations are discussed. View full abstract»

    Objective measurement of the human vertical fusional response to asymmetric disparity presentation was carried out. Ramp disparities evoked mostly monocular eye movements. Step disparities evoked binocular eye movements which began with conjugate saccades followed by slower vergence movements. The two saccade amplitudes were approximately equal, and each was greater than half of the disparity. Mot... View full abstract»

    We have developed an iterative computer-based algorithm which determines Pso while avoiding direct inversion of the relationship between blood oxygen partial pressure and oxyhemoglobin saturation. Blood sample measurements and the value of P50 are used, together with carboxyhemoglobin data, as necessary, to calculate blood oxyhemoglobin saturation and oxygen content. View full abstract»
