|Embedor Technologies' Xnode Smart Sensor is a powerful and versatile wireless sensor platform designed specifically for SHM applications. The Xnode's capabilities have recently been expanded with the addition of a trigger accelerometer and a high-fidelity, 32-bit 3-axis accelerometer. The former allows for for event-triggered data acquisition, necessary for applications such as seismic monitoring and rare event detection. The latter makes the Xnode capable of measuring the structural response from low-amplitude ambient vibrations, e.g. in very stiff structures. In this demonstration, we will showcase the combination of these capabilities for high-fidelity rare event monitoring without losing any data from the event, which is common with other wireless sensor platforms. As excitation is applied to a model structure, the Xnode will autonomously detect the vibration and seamlessly stitch the data from the two accelerometers, starting seconds before the triggering event. This demo highlights the utility of the Xnode for applications like impact detection and rapid condition assessment. Click here to access Embedor Technologies Website.|
|We are an innovative and disruptive start up focused on advancing the capabilities of IoT sensors by providing them power wirelessly.

|Data visualization is an important aspect of the SHM process. The ability to communicate effectively between various involved parties working on an SHM project is frequently the key to success in long-term SHM applications. Our work presents a method for integrating SHM data and meta-data into an informational modelling (IM) and virtual reality (VR) environment. By presenting SHM data and meta-data in an intuitive and interactive manner enabled through IM/VR, communication during projects, an understanding of the SHM system, and an understanding of SHM data will be fostered. As a case study, the method implementation on Streicker Bridge is presented. click Here for SHM lab at Princeton; click Here for HS lab at Princeton.|
|In this video demonstration, we have implemented a practical capability to automatically perform region-of-interest (ROI) localization and classification using UAV images. A large volume of images from a full-scale highway sign truss is collected using a drone. A selected target inspection region (welded connection in our demo) on each image is automatically localized, and less useful ROIs, such as those corrupted by occlusions, are further filtered using a robust image classification technique, called convolution neural network algorithms. We will also demonstrate, with thousands of images collected from the structure, our in-house software implementing these techniques. click Here for Intelligent Infrastructure Systems Laboratory (IISL), Purdue University.|
|One of the issues with current manual structural inspections is that there tends to be variance across inspectors with regards to the current structural integrity of infrastructure. This problem is going to be exacerbated as we move towards building structures with design lives on the order of hundreds of years. Over these time frames even language can change so it is becoming increasingly necessary to develop tools that capture high-resolution structural inspection information in an unambiguous manner. Emerging augmented reality headsets offer a promising solution to the problem of collecting high-resolution, 3D structural information in an on-the-fly manner and we will demonstrate our current work in this area. click Here for Los Alamos National Laboratory.|
|Real time damage detection and classification via a simple Power Spectral Density (PSD) based statistical time series method is demonstrated on a laboratory-scale ship hull structure. The hull structure consists of a number of vertical and horizontal aluminum plates and beams jointed together via bolts and rivets. The detection and classification of damages, each corresponding to a loosened bolt, is achieved based on a single 10 seconds long vibration acceleration signal within the 0-850 Hz frequency range. The method automatically detects and classifies each considered damage, and is also capable of identifying the healthy state following proper structural repair (bolt re-tightening).

|The ARMOR Lab at UC San Diego aims to derive innovative solutions for safeguarding our structural/human assets using multifunctional materials with performance accentuated by tomographic methods. We will showcase a system that enables noncontact and subsurface damage quantification and localization. Like computed tomography, this system generates cross-sectional images of a structure; however, it uses electric fields to interrogate the system to generate electrical permittivity images, where locations and magnitudes of permittivity changes can be directly visualized. Embedded nanocomposites sensors further enhances damage selectivity. Its applicability for monitoring corrosion, strain, and pH will be demonstrated. Click here for the ARMOR Lab.|
|The University of Nebraska-Lincoln (UNL) team has developed an automated acoustic scanning system for rapid evaluation of concrete bridge decks. Multi-channel MEMs microphones are used to continuously collect acoustic signals generated ball chains, and a RTK GPS system provides real-time positions of the testing system. The system is able to scan a typical bridge lane in less than 3 minutes and generate a defect map immediately after the scanning. Click here for the NDTCE Lab.|
|We will introduce fully non-contact mobile pulse-echo ultrasonic propagation imager (PE UPI) based on laser ultrasound as an in-situ nondestructive evaluation tool. The mobile PE UPI provides an excellent solution for visualizing through-the-thickness damage and defect in composite structure, which is commonly used in real world structures. This system consists of compact scanning laser head, two-axis translation scanner and UPI controller and is able to inspect the structure by using the compact scanning laser head which combines generation and sensing laser beams to scan the structure in high speed and high spatial resolution. Inspection result can be represented in real-time not as a two-dimensional image but as a three-dimensional video which shows the propagation of through-the-thickness ultrasound as bulk wave based on pulse-echo ultrasonic wave propagation imaging (PE UWPI) technique. The system also provides post processor for damage visualization such as multi-time frame amplitude mapping, defect pointing function, and polygon defect area calculation. In a 5 minute video live, we will show the principle and practical operation of mobile PE UPI as well as practical applications in real world structures using mobile PE UPI.
