Wireless bike brake system has the highest GPA ever
Color us a yellow shade of mendacious, but if we designed something that works 99.999999999997 percent of the time, we'd probably round off and give ourselves a big ol' 100 percent A+. We'd probably throw in a smiley faced sticker, too. Computer scientist Holger Hermanns, however, is a much more honest man, which is why he's willing to admit that his new wireless bike brake system is susceptible to outright failure on about three out of every trillion occasions. Hermanns' concept bike, pictured above, may look pretty standard at first glance, but take a closer look at the right handlebar. There, you'll find a rubber grip with a pressure sensor nestled inside. Whenever a rider squeezes this grip, that blue plastic box sitting next to it will send out a signal to a receiver, attached to the bike's fork. From there, the message will be sent on to an actuator that converts the signal into mechanical energy, and activates the brake. Best of all, this entire process happens will take just 250 milliseconds of your life. No wires, no brakes, no mind control. Hermanns and his colleagues at Saarland University are now working on improving their system's traction and are still looking for engineers to turn their concept into a commercial reality, but you can wheel past the break for more information, in the full PR.
