Excessive mass and poor balance of protective headgear can lead to fatigue and neck muscle strain with potential long-term consequences. Measurement of these parameters relative to the human head has been time consuming and cumbersome.
Biokinetics' helmet Mass Property Instrument (MPI) is a test device that will evaluate the mass moment of inertia and the centre-of-gravity of a helmet system in the three orthogonal directions. This information is extremely useful for assessing the dynamic stability and feel of a helmet worn in a high-movement environment as well as the weight-borne user effects from add-on accessories such as night-vision goggles.
