Chip-enabled soccer ball

The chip is a ball of Adidas, the Fraunhofer Institute for Integrated Circuits in Erlangen and the company Cairos Technologies AG developed football with an integrated ASIC chip and an integrated transmitter for sending data.

Technology

The chip is suspended in the middle of the ball crossing the goal line and sends radio signals in less than a second for the referee to a receiver on the wrist.

Initial tests found in the stadium in Nuremberg, where twelve antennas in light masts and on the sidelines in the arena took over the data transmission. The antennas are connected via fiber optic cable with a Linux - based server, which performs the evaluation of the data.

In July 2012, finally, FIFA agreed to the introduction of goal-line technology, so the use of electronic tools for goal - finding to, however, these " smart ball" could not prevail solution and so the choice falls between the systems Hawk-Eye and GoalRef.
