Zusammenfassung:A method is disclosed. The method includes providing power to a device including a housing, determining an initial impedance at a first time between a first location of the housing and a second location of the housing, measuring a measured impedance at a second time following the first time between the first location of the housing and the second location of the housing, comparing the measured impedance to the initial impedance, and initiating a breach action if the measured impedance is not substantially equal to the initial impedance. A power interruption to the device occurs between the first time and the second time. Measuring the measured impedance includes using a swept voltage or a swept current source.
