If you've ever ridden a subway, you've probably experienced a bump in the tracks that could send your coffee onto another rider.

George Lederman, doctoral candidate at Carnegie Mellon University, wants to fix that, though you may never notice his work.

Piezoelectric sensors fixed to train cars with electrical tape are at the heart of Lederman's monitoring equipment. They measure changes in pressure, acceleration, temperature, strain and force by converting these changes into an electrical charge.

Meta Mesh is making one Pittsburgh neighborhood one of the few places in the country with a free community wireless network--called a mesh network. By putting up what are called nodes--routers along with more substantial antennas--Meta Mesh offers Wi-Fi along Warrington Avenue in the Allentown business district.

Adam Longwill got the idea for Meta Mesh a few years ago when he was using a slow DSL connection. As he considered borrowing his neighbor’s Wi-Fi but instead he came up with a better plan.

 

“It got me thinking about, ‘How would I connect to my neighbors?’” Longwill said. “I would need a bigger antenna, a parabolic antenna. And I started looking at how radio frequencies work, and how I could get better range, better speed. And then I thought ‘Wouldn’t it be cool if we could have a whole neighborhood doing this?'”

A Pittsburgh-area doctor is going digital as part of a growing trend of psychiatrists offering their services online.

“Just log in on your phone, get a face-to-face video assessment on a HIPAA- compliant secure platform,” said Dr. Matthew Keener, who created Blackbird Health. “You don’t have to drive all the way across town, you don’t have to wait in a waiting room.”

The American Telemedicine Association says more than half of all U.S. hospitals now use some form of telemedicine.
