Patent Images
1. For use on power equipment having at least one dangerous portion, a method of detecting dangerous proximity between a person and the dangerous portion, the method comprising:
- generating a high voltage;
applying the high voltage to the dangerous portion, where the high voltage is sufficient to cause an electrical discharge arc between the dangerous portion and the person'"'"'s body when a portion of the person'"'"'s body comes within a predetermined distance from the dangerous portion;
providing an electronic circuit adapted to detect when an electrical discharge arc between the dangerous portion and the person'"'"'s body occurs;
detecting through the electronic circuit when an electrical discharge arc between the dangerous portion and the person'"'"'s body occurs; and
triggering an action to mitigate potential injury when the electronic circuit detects the occurrence of the electrical discharge arc.
