Nevada Patent of the Month – July 2023
Advanced Materials and Devices Inc. was founded to develop, test, evaluate, and commercialize wearable blast sensors and advanced vehicle suspension systems.
Currently, the underwater measurement of blast pressure is limited to laboratory sensors that can be operated by experts in the field. These sensors are bulky, wired and not wearable. For underwater blast pressure exposure, no wearable sensor exists. Advanced Materials and Devices has worked to develop solutions for this unmet need, developing a single sensor capable of measuring both underwater and in-air blast pressures. With its lightweight and wearable design, the wearable universal blast sensor aims to provide accurate data on blast pressure exposure for personnel, animals, structures, and vehicles.
Traditional blast sensors have faced limitations in terms of directional sensitivity, sampling rates, resolution, and ingress protection. Advanced Materials and Devices has addressed these shortcomings by incorporating multiple built-in sensitivities so that the device can accurately measure different amplitudes of blast pressures, both in the air and underwater.
The wearable universal blast sensor employs advanced technology to trigger recording when preset threshold parameters are reached. It utilizes a rolling memory buffer to capture pre- and post-trigger blast data, ensuring comprehensive data collection for analysis. The device also includes indicators such as colored indicator lights, digital displays, sound sources, and tactile feedback sources to provide real-time feedback on blast exposure magnitude.
One of the notable features of the wearable universal blast sensor is its ability to process blast data directly on the device itself. This edge computing capability enables efficient and immediate analysis of blast exposure parameters. Additionally, the sensor can save measured data for download and post-processing, allowing for further in-depth analysis by medical professionals and researchers.
The wearable universal blast sensor is equipped with pressure sensing transducers, blast parameter sensing transducers, analog-to-digital converters, rolling memory buffers, and controllers. These components work together seamlessly to ensure accurate data capture, analysis, and storage.
With the invention of the wearable universal blast sensor, Advanced Materials and Devices aims to provide medical professionals and researchers with a valuable tool for understanding and assessing the effects of blast exposure. By collecting data on blast pressures and other parameters, the device contributes to the creation of a comprehensive medical database, facilitating research on blast-related injuries and their long-term effects.
