Seems to be related: http://www.wired.com/2013/09/building-a-better-stronger-safe...

Also, von Pragenau's obituary (he died a few months before the Wired article was published, apparently): http://www.hamptoncovefuneralhome.com/fh/obituaries/obituary...

Not related per se but for that reason all the more interesting. The Wired article refers to a different 1984 patent grant for another Pragenau invention which, had it been utilized by NASA, would have prevented the Challenger accident. It seems Pragenau is an un[der]sung hero.
