Wireless Bicycle Brake

November 3, 2011 | Filed under: Science | Posted by:

Computer scientists at Saarland University developed a wireless bicycle brake and demonstrated its efficiency on a cruiser bike. Furthermore, they confirmed the brake system’s reliability through mathematical calculations that are also used in control systems for aircraft or chemical factories.

NOW YOU ARE WONDERING WHAT A CRUISER BIKE IS?

The cruiser bike is more similar to an Easy Rider motorcycle without an engine block than it is to a traditional bike. However, looking at the straight, elongated stem, it is readily apparent what makes the newly developed system so special. The bicycle has neither a protruding brake lever to control the front brake, nor a brake cable snaking down the frame. However the Saarland scientists should now mathematically verify the correct functining of algorithm.

After examing the brake prototype with algorithms they found out that the brake works with 99.999999999997 percent reliability. This implies that out of a trillion braking attempts, it will have three failures.Researching the wireless bicycle brake was funded within the special research field “Automatic Verification and Analysis of Complex Systems (AVACS)” by the German Research Foundation. Its results are documented in the scientific paper “A Verified Wireless Safety Critical Hard Real-Time Design,” published by the Institute of Electrical and Electronics Engineers (IEEE).(I AM ALSO A MEMBER OF IEEE.):-)
