SOFTWARE, SOFTWARE MODULES
1. Dynaman occupant simulation software.
2. Airman software to predict level of injury to various parts of the body
from penetrating fragments.
3. WAFAC software to simulate motion of a person wearing a life jacket in
water. The software also estimates the heat loss from the head of the
person in water.
