	[* black] Removing the speed sensor.
	[* black] Aptly named, the speed sensor monitors the speed of the spinning shaft. Should things get out of hand, the sensor will shut off the motor.
-	[* black] The speed sensor most likely uses the [link\|http://en.wikipedia.org/wiki/Hall_effect\|Hall effect] to tell the control circuitry how fast the shaft is spinning.

+	[* black] Blendtec informed us that the Total Blender includes what they call a "hammer-fire" system. The main IC controller will trigger this system if it detects that the blade stopped spinning. The controller will send a series of strong electric pulses with the intent to free the blades from the obstruction. If that fails, the IC will shut off the motor to prevent any damage.
