Proposal 31: Long Jump: electronic detection system for jump and landing marker [ Revision 1 ]
Committee: JumpsSubmitted on 2015-03-21
Status: Set-Aside (Reviewed from March 31, 2015 to April 10, 2015)
Background
At Unicon16 first time a electronic Monitoring of the jump and landing marker was used. It worked perfect and gave the judges first time the possibility without risk for him to distinguish between slight touch or not. Therefore following modification in rulebook should be done add of electronic Monitoring
Proposal
Old:
2.19.2.3 Judging
The rider must clear the jump marker and the landing marker without touching them; he also has to clear the finish line to make it a valid jump. Jump distance is measured between the outer edges of the jump and landing marker. There has to be at least one judge (better two) to look at the markers. For national championships and Unicons, two judges are always needed; one to observe each marker.

For national championships and Unicons, two judges are always needed; one to observe each marker.
Aditional it’s recommended especially for Unicons to monitor the touch of the markers with a electronic sensor mounted at each marker. The sensor princip must be clearly able to separate a vibration of ground to the noise for touching the markers.
Body
The electronic Monitoring of the markes allows the judges to get additional informations if the markers were touched or not. Sometimes the judges put their finger on the marker. But it's very dangerous.
The recommended sensor princip is used in all Airbag control units we all have in the vehicles.
Therefore the electronic Monitoring will be a very good additional Option.
Description:
If you touch a Metall part you will generate Sound, the sensors are very sensitive, therefore touching the metal marker you can see a very big Signal, touch the ground (without touch the marker) you only see a very small misuses Signal.
For such sensors tolerances are not relevant, if already a small touch happens you see a huge signal
