hen created, was the most realistic model to that date. Full movement of the limbs, torso, neck and head allowed the dummy to be placed in any position. Dynamic Dan was created and used for testing ejection seats, vibration tests, parachute opening shock tests and other tests involving aircrafts. The OPAT dummy was created and was very helpful in collecting information about seat belts because of its human like clavicle and floating scapula and a rib cage that is very similar to a humans. This dummy is still commercially available. In 1973 Repeatable Pete was developed. It was designed to provide accurate data from frontal impacts and lateral impacts. Because of the lack of repeatability and reproducibility, this model was never commercially available. The Hybrid III, 50th percentile male, weighs 172.3 pounds was made in 1973. It was made to improve the impact response of the test dummy to be more like a human. This dummy has a variety of optional equipment available. Because of this it is one of the most versatile test dummies available. The Hybrid III, 5th percentile female weighs about 108 pounds and is a smaller scaled version of the Hybrid III 50th percentile male, both of these models are still widely used. The Side Impact Dummy (SID) and the European Side Impact Dummy (EUROSID) were made to collect data on human response during a side impact crash, and are still being used.The test dummies are put through many tests to make sure vehicles are safe. In testing new side air bags, high speed video cameras are place along the sidelines of the testing area. There are also two on board cameras. Red chalk is put on the dummys head and torso to mark the spot where the body hits the steering wheel during the impact. 31 continuous measurements are taken from the dummy during the crash. This information is then analyzed to help produce new and improved automobile designs. In some dummies there are three accelerometers inside the head that me...
