from the "Inspiration" section:

Don went out with the traffic investigation squad to understand the accidents and to retrieve the helmets. What he discovered was bone fragments, fluid and teeth embedded into the foam but the liners showed little or no evidence of damage. This is where Don’s interest in foam liners started. Don Morgan is a Physicist from Brisbane.

The invention has already been submitted and passed double-impact tests in Europe.
