DETERMINING ENCLOSURE BREACH ELECTROMECHANICALLY
First Claim
1. A method for determining a structure breach, the method comprising:
- driving a sensor, provided in the structure, with a constant frequency signal, the sensor comprising a first conductive element and a second conductive element, the first conductive element being substantially parallel with the second conductive element, a standing wave pattern being induced on the sensor by the constant frequency signal reflecting off a termination point of the sensor;
measuring at least one characteristic of the sensor caused by the voltage standing wave pattern; and
determining that a breach has occurred in the structure when the measured at least one characteristic varies from a previously determined value by a predetermined amount.

Abstract
A structure breach may be determined. A sensor, provided in the structure, may be driven with a constant frequency signal. The sensor may comprise a first conductive element and a second conductive element. The first conductive element may be substantially parallel with the second conductive element. A standing wave pattern may be induced on the sensor by the constant frequency signal reflecting off a termination point of the sensor. A least one characteristic of the sensor caused by the voltage standing wave pattern may be measured. A breach occurrence in the structure may be determined when the measured at least one characteristic varies from a previously determined value by a predetermined amount. The first conductive element and the second conductive element may be sandwiched between two layers comprising the structure. The structure may comprise a shipping container floor. The detected breach may comprise an opening greater than nine square inches.
