    Many visual phenomena, in particular, visual discrimination performance as a function of light intensity, have been attributed to a, nonlinearity in the retinal stages of the visual system. A comprehensive analytical quantified derivation of the nonlinearity based upon an optimum processor approach to visual perception is presented. The account follows optimum decision rules described by likelihoo... View full abstract»

    An implantable biotelemetry system is described for multisite temperature measurements with ease of expansion by use of different master circuit boards to accommodate additional channels. Modular construction of the multichannel FM-FM system allows addition or deletion of channels as the experiment requires. The radio frequency carrer osciUlator is tunable to a "quiet" frequency in the 90-105 MHz ... View full abstract»

    A real-time echocardiographic tracking system (ETS) has been designed and implemented to provide continuous real-time information on the position and motion of cardiac structures such as the anterior and posterior left ventricula wall. The ETS is capable of tracking two separate cardiac structures simultaneously and simplifies the task of extracting the dynamic positional information from aln M-mo... View full abstract»

    The reliability of fetal heart rate (FHR) from external abdominal-lead electrocardiographic waveforms depends upon the R-wave detection capability of the monitoring device. Assuming that the maternal component of the ECG is canceiled by techniques described elsewhere [1]-[4], we are left with a fetal electrocardiogm (FECG) which may be conrupted by high noise levels. This paper describes several d... View full abstract»

    A theoretical study of the electrical resistance of open tip glass microelectrodes based on the main physicochemical phenomena occurring at the microtip is described. An analytical expression for the total resistance of a microelectrode is derived from a model which assumes an electrically insulated glass wail. The model takes into account the diffusion process through the open tip, the ionic cond... View full abstract»

    A method of analyzing neuronal spike train stimulus-response data which enhances temporal features and reduces nonstationarities is described. First, a Parzen estimate of the post-stimulus density function is computed by convolving spike events with Gaussian kernels. Second, successive segments of the spike train are correlated to a template, and the temporal relationship between segments is adjus... View full abstract»

    A procedure to obtain the optimal time constant in low-pass filtering of surface EMG has been developed. The performance index which determines the optimality of the time constant considers the sensitivity of the filter and the reproducibility of the filtered output. In our procedure, the optimal time constant can be easily calculated from a nonlinear equation which is characterized by the autocor... View full abstract»
