First Claim
Patent Images
1. A method for monitoring the temperature of an element comprising:
- powering a circuit attached to the element to inject charges into a charge storage element of this circuit;
removing the power from the circuit;
causing an evacuation of the charges from the charge storage element if the temperature exceeds a temperature threshold;
powering the circuit; and
reading an amount of charge present in the charge storage element.
