NHL puck is going high-tech

The hockey puck as it’s been known forever, that humble 6-ounce chunk of hard rubber patented decades ago by Bruins general manager/coach Art Ross, has left the building.
There’s a new kid in NHL rinks, and this is fitted with a tiny embedded battery, a circuit board roughly the size of a half-dollar, and 6-inch-long tubes that emit infrared light at 60 pulses per second — fast, yet still two beats behind Connor McDavid on a breakaway.
“Crazy, isn’t it?” said the NHL’s Dave Lehanski, an executive vice president who has helped steer the puck’s development the last 7-8 years. “It almost has a life of its own.”
