Classification: CPC G  H | IPC G  H

Claim 9:
10. A method of operating an electronic device having a printed circuit, a resistive thermal device (RTD) embedded within the printed circuit, a data acquisition system (DAQ) coupled to the RTD over conductive vias in the printed circuit, an electrical component mounted to the printed circuit, and one or more processors, the method comprising:
measuring, using the DAQ, a resistance of the RTD, the RTD being embedded within stacked layers of the printed circuit;
identifying, using the one or more processors, a temperature within the printed circuit based on the resistance of the RTD measured by the DAQ;
reducing, using the one or more processors, power consumption by the electrical component when the identified temperature exceeds a threshold temperature, wherein the electronic device comprises a strain gauge on the printed circuit;
measuring, using the DAQ, an additional resistance of the strain gauge; and
identifying, using the one or more processors, a strain on the printed circuit based on the additional resistance of the strain gauge measured by the DAQ.
