00:14mechanism is very sophisticated, but the technology behind it is actually quite simple.
00:21The blade carries a small electrical charge.
00:24This charge is continuously monitored by a digital signal processor.
00:29When contact is made, the human body absorbs some of the charge, causing the voltage to drop.
00:37The drop in voltage triggers a quick-release aluminum break.
00:41A heavy-duty spring forces the break into the teeth of the spinning blade.
00:47The teeth dig into the aluminum, stopping the blade cold.
00:51The blade's momentum forces it to retract below the table, and the motor is automatically shut off.
