    The inverse problem in electrocardiography is attacked via the development of a model appropriate for the computation of epicardial potentials from a knowledge of heart and torso geometry as well as surface potentials. The model takes the form of an integral equation of the first kind in which the kernel is interpreted as a Green's function. A theoretical investigation of system independence in th...

    The simulation of a system to perform an automated leukocyte differential has been achieved through the measurement of certain features or parameters on the cell image. Using photomicrographs on Kodachrome II-A film of Wright's stained leukocytes, the following four features have successfully separated five normal cell types (neutrophil, eosinophil, basophil, lymphocyte, and monocyte): 1) nucleus ...

    Various types of human injury attributable to nonionizing radiations are presented. Because of the unique combination afforded by the optical qualities of the eye and by the differential diagnostic features of resultant ocular pathology, an ophthalmological examination frequently can provide the signature indicating whether visible or invisible radiations produced the injury. For example, visible ... View full abstract»

    A small, inexpensive, integrated circuit, asymmetric, triangle generator for the calibration of cardiovascular waveform differentiators is described. The calibrator produces a simulated pressure waveform in which the slopes of the leading and trailing edges are precisely and stably set to represent specific values of dP/dt in millimeters of mercury per second. The waveform is clipped to give a zer... View full abstract»
