Using the iPhone (or any mobile smartphone or tablet device, really) for medical purposes isn’t a new thing, but it’s nice to see the applications people cook up. Just recently at Disrupt we saw Smartheart , and apps like Skin Scan are decentralizing some simple self-monitoring tasks like melanoma detection.

Five mechanical engineering students from the University of Pennsylvania were provided with one year and a significant sponsorship budget and to design and create a next generation bike, the result : The Alpha bike. The new Alpha bike concept drops the traditional gears and chains and replaces them with a drive system integrated into the frame of the bike. The drive is provided by a new SWIFT Drive Technology which is an Integrated Free-Fixed Transmission that uses an electromechanical actuated clutch to switch the bike’s configuration between fixed-gear and free-wheeling modes.
