Abstract : In order to evaluate impact protection devices, an impact injury model for restrained humans in a crash environment must be developed. Disruption of the functioning of the central nervous system is an important consequence of impact injury involving the head and neck, and is an important consideration in the development of a useful impact-injury model. Ultimately, neurophysiological criteria are desired. Evoked potentials (EPs) are likely to provide appropriate neurophysiological information, but quantitative analysis of EP data presents considerable difficulty. Among the technical problems encountered is efficient digitization of large amounts of EP data presents considerable difficulty. Among the technical problems encountered is efficient digitization of large amounts of EP data. This report presents detailed specifications for a high-performance analog-to-digital conversion subsystem suitable for various aspects of such work. Procedures utilizing various aspects of the design presented have been have been found to be effective. In the future acquisition of A/D conversion hardware, the design presented here should be considered. (Author)
