Accelerometers to the rescue
April 18th, 2008Neat stuff! A pretty cool solution for making the cyclist more visible in the dark.
An American inventor based in the UK has won an international design competition.
Michael Chen, 28, won a £6,000 prize for his Reactiv cycle jacket, which changes colour as the cyclist brakes.
How it works
The jacket uses an accelerometer to sense movement, changing the colour of LEDs on the back from green when accelerating, then to red when braking.
A tilt switch in the jacket also makes LEDs in the arm flash amber when the wearer lifts their arm to indicate a turn.
