ONE TIME OPERATING STATE DETECTING METHOD AND APPARATUS
First Claim
Patent Images
1. A one-time operating state detection device comprising:
- a pair of contacts;
a member electrically coupling the pair of contacts, the member adapted to be only once movable to change the electrical coupling between the contacts; and
a detector, wherein the detector is configured to detect the change in the coupling between the pair of contacts when the member is moved.
