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.

A building monitoring computer system for monitoring building integrity may be provided. Various types of sensors may be embedded throughout or within certain portions of different types of building or construction material making up the building, such as within roofing, foundation, or structural materials. The sensors may be in wireless communication with a home controller. The sensors may be water, moisture, temperature, vibration, or other types of sensors, and may detect unexpected or abnormal conditions within the home. The sensors and/or home controller may transmit alerts to a mobile device of the home owner associated with the unexpected condition, and/or that remedial actions may be required to repair the home or mitigate further damage to the home. The sensor data may also be communicated to an insurance provider remote server to facilitate the insurance provider communicating insurance-related recommendations, updating insurance policies, or preparing insurance claims for review for home owners.

A fluid leakage diagnosing device includes: when fluid leakage relating to a pipeline is being diagnosed by employing adaptive signal processing to suppress a component of a disturbance vibration contained in a vibration measured at a prescribed location in the pipeline, an acquiring unit that acquires distribution information that is associated with a characteristic of the pipeline and represents an actual distribution result of a value of a parameter in the adaptive signal processing when performance of suppressing the component of the disturbance vibration satisfies a criterion; an estimating unit that, based on the distribution information, estimates a probability density at which the value of the parameter with which the performance satisfies the criterion exists; and a determining unit that, based on the probability density estimated by the estimating unit, determines a range to search for the value of the parameter in the adaptive signal processing.

A computer-implemented method and system for determining placement of a sensor component on a utility pipe. Data relating to the utility pipe is inputted which is processed to generate one or more variables. One or more models are trained, via the one or more variables, to produce an output indicative of a likelihood of failure variable associated with the utility pipe from each model. The outputs from all models are preferably combined into an ensemble output indicative of a likelihood of failure associated with the utility pipe. A consequence of failure variable associated with the utility pipe is determined preferably utilizing a plurality of weighted variables. A sensor placement determinative variable is then determined contingent upon the ensemble output and the consequence of failure variable associated with the utility pipe. Feedback data is then provided indicative of physical placement of one or more sensor components associated with the utility pipe based at least in part on the sensor placement determinative variable.

The invention relates to a method for leakage detection on an object flown through by a medium, in particular a pipe or a pipeline. According to the invention, a pattern is identified in the determined values for the change of the flow rate and the pressure of the medium and for a temperature change, and a probability for the presence of a leak is determined based on the identified pattern and due to self-learning systems.

Methods, systems, and computer-readable storage media for providing high-resolution assessment of the condition of pipes of a fluid distribution down to the individual pipe stick. An acoustic sensor is placed in acoustical communication with a pipe at one end of a target segment. An acoustical wave is generated in the pipe at a first out-of-bracket excitation location while signal data is recorded from the acoustic sensor. Timing information regarding the arrival at the acoustic sensor of reflections of the acoustic wave from pipe joints in the target segment is extracted from the recorded signal data, and a time delay between reflections from consecutive pipe joints is computed. An acoustic propagation velocity in a pipe stick between the consecutive pipe joints is then computed based on the time delay and a length of the pipe stick. A condition of the pipe stick is determined based on the computed acoustic propagation velocity.
