New Devices Help Track Olympic Winners

Darren writes "Athletes are going faster, higher and longer and as a result the technology that measures their feats at the Olympics needs to keep up. As a result a number of new devices to help track winners, losers at the Games have been developed, including microchips on marathon runners' shoes, ultrasensitive touch pads in the pool, radar guns at the beach volleyball and cameras that take 1000 images per second."

      You are correct, that is why ChampionChip and other RFID timing systems are not used for high speed races such as the short-distance track events. They are mostly used in road races (5K, 10K, etc) and other events such as triathlons.

      Some RFID manufacturers have developed a chip that is placed in the bib (race number) There are a few problems with this though.

      1. Reads - Champion Chip and other RFID systems usually operate with a pad on the ground and the read height is a factor of outside EMI. On a good day I can get a ChampionChip to read at about waist level, so accurately reading a chest-level tag would be difficult. Of course we could crank up the power on the readers but that may not be the safest environment. There are some European systems that use an exposed antennae but they are not actually approved by the FCC or EU since they emit quite a bit of EMI into the air.

      2. Cost - The chest level (bib) chips need to be an active chip to increase reads. Active chips are more expensive than passive chips (what Champion Chip uses) and have a shelf life since there is a battery in there. So as a race timer/organizer what do you do for a large race such as a marathon? If an active chip in the bib costs say $40 per unit, do you build that into the cost of the race? No. So now you must rely upon the race staff/volunteers to retrieve all the chips, so for each lost chip the race timer is out $40 bucks. Of course you know who lost/kept the chip so you can send them a letter asking for it back, or at least your $40 but the results usually aren't that good.
