Test & measurement systems

Live video production

Broadcast equipment




If you have a challenge in a combined area of fields within electronics, software, physics and video, you can ask Rubytech to develop a solution for you. Developed systems include the ones mentioned on the "Video registration" page, and the ones described in the following paragraphs.

Swimming match finish LEDs

In a swimming match it is often difficult to see who touches the wall first when finishing. Spectators need to check the scoreboard to see who is the winner. To make this easier, a system has been built that shows the winner immediately with LEDs above the winning lane. The first swimmer gets a blinking golden light bar, the second a constant silver light bar, the third a constant bronze light bar. When a record has been swom, a "light show" can automatically be shown. This system is operational in Eindhoven, and was developed for the yearly Swim Cup. It has also been used at the European Championships 2008 and at the European Short-Course Championships 2010 held in Eindhoven.

Moving underwater camera

In order to have smooth video of swimmers while swimming, a camera system has been developed which moves along with swimmers. A special hydrodynamical epoxy body covers the stainless steel housing to reduce drag while moving the camera system.

Swim record line

Will the swimmer set a new record? Half-way the race, this is difficult to judge. After each lap, the record’s lap time needs to be compared to the current lap time. This is a rather cumbesome process. However, when a record line is drawn in the video from a camera, it it suddenly very easy to judge. To be able to draw this line at the correct place in the video, a connection to the electronic time keeping system is required, the lap times of all records, and a continuously updated camera pan, tilt and zoom position. Click the video on the right to see what it looks like during a match. This video has not been edited.

The example shown next to this shows whether swimmers would make their qualification time for the Olympic Games of London. Because this was not applicable for all swimmers, the line was not shown on all lanes. Various lines could be enabled during this competition, each with its own colour: World record, European record, Dutch record, limit for Olympic Games and limit for European Youth championships.
