What is a ChampionChip?
A
ChampionChip is a miniature transponder in a specially designed plastic
housing. This device contains a chip in combination with an energizing
coil. These elements are encased in a waterproof glass capsule, meaning
the ChampionChip can be used under all conditions (wet, dry, cold and
hot).
The ChampionChip can be worn in different ways. For
running races, the ChampionChip is attached to the runner’s shoelace. In
triathlons it is attached to an ankle bracelet.
There are no batteries in the ChampionChip. The
transponder is passive until moved into a magnetic field, generated by a
send antenna. Here the energizing coil produces an electric current to
power the chip. The transponder then transmits its unique identification
number to a receive antenna. The whole procedure takes approximately 60
milliseconds and is repeated continuously.
How
does the ChampionChip System work?
The send and receive antennas are cast in thin tartan
mats. These antenna mats are placed at the finish line and other timing
locations. They are connected to a Yellow Box at the side of the road,
containing electronics and batteries. Each time an athlete wearing a
ChampionChip crosses the mats, the chip gets energized and sends out its
ID-number. This number and corresponding time are then stored in the
Yellow Box and transferred to a timing computer for further processing.
