My brother has been involved in hockey his whole life. He was a goaltender and has played for a couple of US universities as well as one here in Canada. He played on the Brandon Wheat Kings team and also for the Vancouver Junior Canucks team.
After leaving university he began running his own very successful hockey schools around the world even running them in Japan, Minnesota, & Florida.
He had a couple ground breaking creations he made for his hockey schools, using his background in mechanical engineering.
Here is a newspaper article about his reflex tunnel to measure the abilities and weak points of his goaltending students. They could improve their reaction times without fear of being hit by a real puck. Brilliant. Remember this was before computers were available to regular people.
