word is, it's prone to false positives, and each one costs you $75.00.

Do you mean, that it's like airbags - the safety system works ONCE,

Ayup. And they say $150 up front cost (if installed on the assembly line) and a
$75 cartridge replacement cost, but say nothing of the strain on the arbor and
trunnions when the assembly instantly drops below the table and is jammed to a
stop.
