I'm a bit surprised this hasn't been shared here yet...

Felder introduced it's new "Preventative Contact System" (PCS) at the Ligna trade show in Europe.

This system drops the sawblade in milliseconds using non-destructive electromagnetic repulsion. From what I can tell from info I have found, the detection system is based on proximity or possibly a material behavior algorithm (my phrase) rather than the capacitance method that SawStop uses. This system appears to have two significant improvements over SawStop. 1) non-destructive operation and 2)no actual blade contact required for detection.

Lots of questions remain unanswered.

How does detection work?
Does it infringe on SawStop/Tooltronic (Festool) patents?
Can it be cost effectively applied to less industrial scale equipment ie: cheap tablesaws?
Can it be applied to other equipment such as bandsaws, shapers, jointers, etc?
Will Felder give away their intellectual property to other equipment manufacturers to better mankind?
If the government forces us all to buy Felder tablesaws will we have to speak Austrian?
