Engineering Devices to Treat Epilepsy

Many technologies have been proposed for treating epileptic seizures, with the ultimate goal being implantation of stimulators or drug infusion devices in the brain to abort seizures before clinical onset. Device designs range from “blind” stimulators to “intelligent” devices, which are triggered by...

More-Realistic Digital Modeling of a Human Body

A MATLAB computer program has been written to enable improved (relative to an older program) modeling of a human body for purposes of designing space suits and other hardware with which an astronaut must interact. The older program implements a kinematic model based on traditional anthropometric...
