    The development of an auditory cochlear prosthesis which works by direct electrical stimulation of the auditory nerve creates the need for a multielectrode stimulation array which is small in size, rugged, resistant to electrolysis, and stable and reproducible in its electrical and mechanical properties. This paper describes the fabrication of such microelectrode arrays using planar lithographic t... View full abstract»

    During strong voluntary effort it is rarely possible to identify the action potentials from single motor units. In large muscles the most selective recordings are obtained with bipolar wire electrodes. To elucidate this experimental finding we have calculated the extracellular field around a single muscle fiber from an intracellular muscle action potential. This model showed that the selectivity o... View full abstract»

    After preliminary experiments that pointed out the extreme cleverness with which perceptive individuals unintentionally used subtle auxiliary clues to develop impressive records of apparent magnetic field detection, we developed a heavy, tightly sealed subject chamber to provide extreme isolation against such false detection. A large number of individuals were tested in this isolation system with ... View full abstract»

    A flow-system instrument is described in which the light scattered by a biological cell is detected simultaneously at 32 angles in the forward direction as the cell passes through a focused laser beam at 10 m/s. Cluster analysis is applied to the scatter pattern data to enable discrimination among cell types. View full abstract»

    Over the last few years methods have been developed for recording chronically from mammalian nerves with implanted electrodes contained in silastic cuffs. The impedance of the electrodes and the changes that take place over time were studied. Platinum-iridium electrodes remain stable over long periods of time, whereas the impedance of silver wire electrodes increases and eventually the silver frac... View full abstract»

    Single bubbles ranging down in size to under 1 ¿m (less than capillary size) can be noticed, localized, and measured in ultrasonic images of intact subjects using 7.5 MHz ultrasound for which the wavelength is 200 ¿m. Subjects included humans, fish, and guinea pigs. A combined brightness modulation and deflection display was most effective. Bubble reality during decompression and association wit...

    This paper deals with the basic problems of biped gait control. The mechanical structure of the biped body has been reduced to the simple mathematical inverted pendulum. Due to the assumption that the entire mass of a body is concentrated in one point, the control reduces to the proper choice of supporting points, obtained by setting the legs on the ground surface. The process of a gait is conside... View full abstract»

    A single stimulation is applied at the desired time during a breathing cycle. The interval (TR) between the onset of the stimulation and that of the subsequent inspiration varies with the time (ts) when the stimulation is applied. The relationship between ts and TR is piecewise linear. Further experiment shows that this relationship holds for the case of a double stimulation as well. A theory of s... View full abstract»

    An electronic differentiator specifically for low-frequency signals is described. The difference between a signal and its staircase approximation is computed; the peaks of this function approximate the time derivative of the input signal. By regulating the width of the steps in the staircase function, very slow signals can be differentiated. View full abstract»

    A computer-linked instrumentation system for studies of blind mobility is described. The system uses mechanical position sensing, and is capable of monitoring the position of a moving subject to within approximately 2.5 cm over a large area (80 m2). This enables the computation of quantitative performance indices based on body trajectory through the environment. Head-mounted mobility aids with aud... View full abstract»

    The design of a unity-gain buffer amplifier in which an extremely low input capacity is achieved by bootstrapping the entire input stage, including the power sources, which was published in 1973 and further discussed in 1976, needs redesigning in order to make it less critical with respect to the choice of components. The new design is stili very simple and based on commercially available operatio... View full abstract»

    It is noted that a meaningful method of extracting information from the EEG must take into account the current understanding of the origin of scalp-recorded brain electrical activity, as well as many application-specific details. In previous studies which considered these points, useful information has been derived from EEG recordings. View full abstract»
