Aprica, Inc, a Japanese manufacturer of child safety and comfort products funded the development of the 3.4 Kg infant dummy. This biofidelic infant dummy is well instrumented and has been used by Aprica to design and evaluate child seats. The dummy has also been used in "Shaken Baby" tests.
An innovative abdominal load and abdominal penetration measurement system has also been developed by GESAC. Information about these measurement systems are available in the page titled "Literature". Links to some papers on these sensors are also available on the same page as are links to documents detailing response of the dummy to calibration tests.
