Development

If you have a challenge in the combined fields of electronics, software, mechanics, underwater technology, sports timing analysis and video direction, 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.
This system is currently undergoing a speed improvement.

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. However, when a record line is drawn in the video from a camera, it it suddenly very easy to judge. A connection to the electronic time keeping system is required, as well as a continuously updated camera pan, tilt and zoom position, to project the line at the correct place in the video.

Electronic underwater swim lap counter

An underwater lap count display system is currently being developed, for use at long distance swim races in a pool. It uses data from the official electronic time keeping system to display the correct lap count, preventing human counting errors. The swimming can simply look down on the pool floor and does not need to rotate his/her body in order to see the lap counter held by an official at the turning side.

Underwater location system

A system is currently being developed to determine the location of a person in the water. Along with the position, other data such as body rotation or heartbeat can be transferred. For swimming this allows detailed rhythmic analysis. For team sports such as underwater hockey and water polo this allows for strategic game analysis. The data can be collected while in training as well as while in competition.
