dcadwell Posted October 19, 2009 Report Share Posted October 19, 2009 The 0.25 and 0.50 second walking window digital filter in the G-Lab will filter out short duration G spikes. They will not effect the reading as long as the duration of the spike is less than 0.25 seconds. The filter does not average the G level in the walking window. Any G level that does not last the time length of the filter will be completely ignored. <O:p</O:p The reason that the G-Lab is worn on the waist in most circumstances is that for an accurate reading for G forces on a human core, the sensor should be as close to the center of mass of the human as possible. It is easy to generate sustained 5 G’s at your hand just swinging it around. It is very difficult to generate sustained 5 G’s at your center of mass un-assisted by a machine. <O:p</O:p G-Lab meters can be used in non-human applications – mounted directly to a snowboard, in a R/C car or airplane, and so on. But, a direct comparison between a board mounted meter and a waist mounted meter would not be fair since the mass of the board (and weak coupling through the legs to the high core mass rider) makes higher G forces on a board much easier. <O:p</O:p Don Quote Link to comment Share on other sites More sharing options...
Fastskiguy Posted October 19, 2009 Report Share Posted October 19, 2009 What are some common forces for things like jumping up or maybe jumping off of a 4' step? This thing is pretty neat :) Quote Link to comment Share on other sites More sharing options...
