Latest Patents
William H Lewis, Jr holds a patent for a detection apparatus designed to identify structural failures in aircraft. The invention utilizes the strain energy released during a structural failure, which is emitted as a broad frequency acoustic emission. This emission is detected by a piezoelectric crystal that is specifically sized for a preselected natural frequency. The piezoelectric crystal converts the acoustic energy into an electronic signal, which is then filtered to allow only predetermined frequencies to pass through. The filtered signals are processed through a device that matches the line impedance, and a differential amplifier amplifies the signals while rejecting noise. The processed signals are passed through a level detector, which is preset to allow only specific signals to trigger a light-emitting diode, indicating that a structural failure has occurred. Additionally, a built-in tester enables periodic checks to ensure the system's operation.
