  • Helmet Compliance – Case Study

    A weight is dropped on to a motorcycle helmet mounted on a dummy head. The acceleration of the weight and helmet is measured. The DATS Biomechanics software is used to check if the test has met the required profile and to verify whether the helmet meets the necessary standards.

  • Highway Study – Case Study

    The customer uses a Prosig P8004 connected to a custom triaxial accelerometer to study tarmac surfaces. As a car moves over a road it causes a ripple in the road surface. DATS is used to derive displacement from the measured accelerations. The results are used to study different types of surface and changes due to humidity and temperature.
