Georgia Tech inventors have created systems and methods for determining structure intrusions. A signal may be received corresponding to a wave propagating in the structure. Next, the received signal may be analyzed. Based on the analysis in a “passive mode”, a breach may be determined to have occurred in the structure when the received signal indicates that at least one aspect of the received signal crosses a predetermined threshold. Furthermore, based on the analysis in an “active mode”, a breach may be determined to have occurred in the structure when comparing the received signal to a baseline waveform indicates that at least one aspect of the received signal varies from the baseline waveform by a predetermined amount.
- Unobtrusive – does not require on-site inspections
- Efficient – efficent process
- Security industry
- Barrier penetration detection device
- Advanced security system for cargo shipment containers
Threats due to terrorism come in many forms. In some situations, containers carrying goods into a country may be tampered with or contain unauthorized or harmful material. Vulnerability to tampering is a shortcoming in conventional container security devices. Moreover, conventional strategies do not provide a number of tamper-resistant features incorporated into one design. In other words, conventional strategies do not address vulnerability to even simplistic tampering methods.
