Physiological Signal Processor

We will develop a Physiological Signal Processor (PSP) instrument targeted at the ambulatory measurprocessing, recording, and telemetry of complex physiological signals and parameters; specifically EThis work will be accomplished through application of the Field-Programmable Instrumentation (FPI) mdeveloped by DVP under sponsorship of the National Science Foundation. The PSP development will enabof the class of existing and novel portable biomedical instruments requiring a significant degree ofsignal processing capability. The PSP would not only allow portable realizations of existing stationinstruments, but also would stimulate development of new research techniques and methodologies and wcommercial realization of applications and instruments that are currently deemed uneconomical, infeaA prototype of the PSP, an Advanced Cardiac Monitor, will be constructed during Phase I to prove feathrough the implementation of a novel, portable instrument. This instrument will provide for the capheart-rate variability and ventricular fibrillation analysis using Short Time Fourier Transform.
