A method for monitoring health of a valve is presented. The method includes receiving an acoustic emission signal from a sensing device operatively coupled to the valve, selecting a region of interest signal in the acoustic emission signal, determining a plurality of current parameters based on the region of interest signal, and monitoring the health of the valve based on at least the plurality of current parameters, wherein the region of interest signal comprises acoustic emission data generated from initiation of an opening of the valve until the valve is partially opened.

Systems, methods and apparatuses for inspecting a tank containing a flammable fluid are provided. The system includes a vehicle having a propeller, a latch mechanism, a pressure switch, and an inspection device. The system includes a control unit in communication with the propeller, the latch mechanism, and the inspection device, and electrically connected to the pressure switch. The control unit powers on responsive to the pressure switch detecting an ambient pressure greater than a minimum threshold. The control unit receives, from the latch mechanism, an indication of a state of the latch mechanism. The control unit determines that the cable used to lower the vehicle into the tank containing the flammable fluid is detached from the vehicle. The control unit commands the propeller to move the vehicle through the flammable fluid. The control unit determines a quality metric of a portion of the tank.

A device and method for detecting water leaks in building structures relies on sonic and spectral density analyses of sound distortions caused by a subsurface water leak. Structurally, the device includes a microphone connected with a sound amplifier. Also included is a head set and/or a sound analyzer which are respectively connected with the amplifier. In this combination, the microphone is moved across a surface in the building structure to detect an audio signal that is indicative of a subsurface water leak. This audio signal is then aurally evaluated using the headset to identify a sound distortion relative to white noise, or it is visually evaluated by reference to a spectral density presentation of frequencies on the sound analyzer. Operationally, a location of the water leak is determined by moving the microphone along a search pattern of trace lines over the surface being searched until there is a meaningful response.
