David Blois manages condominium properties near Toronto, but at any given time he’s usually also working on several inventions—a solar-powered smoke detector, say, or an age-spot-erasing skin cream. In 1998 he was ice skating at his local rink when an idea popped into his head: a hockey skate that used springs to harness a skater’s kinetic energy. “It’s really hard to invent something new,” Blois says. “As I researched patents, I got more excited. No one had ever tried this before.”
The Steadicam was originally developed to take the shake out of Hollywood chase scenes. Now a California company, Equipois, has given it a new purpose: to help line workers and file clerks. The x-Ar arm reimagines a Steadicam’s spring system to make arms and tools feel weightless, diminishing the risk of repetitive-stress injuries without motors, batteries or external power.
