When light hits Barbara Campbell’s eyes, it triggers no response in her retinas, and no signals flash up her optic nerves to her brain. A genetic disease killed off her retinas’ photoreceptor cells, leaving her completely blind by her 30s. But where her body failed her, technology rescued her. In 2009, at the age of 56, Campbell had an array of electrodes implanted in her left eye, and she now makes her way through the world more confidently, aided by bionic vision.

Her sight isn’t fully restored, not by a long shot, but the darkness has been replaced with rough shapes and patterns of light and dark. “The building where I live has a large light at the entranceway outside,” says Campbell, who lives in New York City. “I hadn’t been able to see that light in 16 years. Now, when I’m walking down the block, I can look up and identify the building.”

The Aftershocks of the EV Transition Could Be Ugly

To avoid unintended consequences, bring realism to the table

The introduction of any new system causes perturbations within the current operating environment, which in turn, create behavioral responses, some predictable, many not. As University of Michigan professor emeritus and student of system-human interactions John Leslie King observes “People find ways to use systems for their own benefit not anticipated by designers and developers. Their behavior might even be contradictory to hoped-for outcomes.”

“Change rides on the rails of what doesn’t change,” King notes, “including people being self-serving.”

When Breathing Sciences Lead to a Mobile Life-Support Device

The compact unit is equipped with an innovative ventilator that recovers oxygen exhaled by the patient

A soldier carrying a MOVES SLC portable life support unit walks over to an injured person on the ground.

Thornhill Medical's mobile life-support device, called MOVES SLC, has been used by military medical teams for five years. The unit can be slung across the shoulder and includes a circle-circuit ventilator and oxygen concentrator that eliminate the need to carry heavy, dangerous high pressure O2 cylinders.

A bomb explodes — medical devices set to action.

It is only in war that both sides of human ingenuity coexist so brutally. On the one side, it innovates to wound and kill, on the other it heals and saves lives. Side by side, but viscerally opposed.

Dr. Joe Fisher is devoted to the light side of human ingenuity, medicine. His research at Toronto’s University Health Network has made major breakthroughs in understanding the absorption and use of oxygen by the body. Then, based on the results, he developed new, highly efficient methods of delivering oxygen to patients.

In 2004, together with other physicians and engineers, he created a company to develop solutions based on his innovations. He named it after the Toronto neighborhood where he still lives — Thornhill Medical.
