ATDs or Anthropomorphic Test Dummies are the real name for test subjects. Although they dont frown about being called dummies they do help researchers understand what happens in airplane crash situations, and how to better protect occupants from injury. With instruments loaded from head to foot, a great deal of information is gained. Thank goodness they have hard heads!
There are more than 20 ATDs in the Dummy Shop, from 6 months old to full sized 95th percentile adults. The most common dummy we use is the Hybrid II-50th Percentile ATD. With fully articulated joints and weighing 168 pounds, this ATD comes under very heavy use in the lab. So it is not hard to see that a little R&R (Rest & Repair) is called for frequently!
