Will UAVs improve how we monitor the environment?

This week's Question: Last week's TechBriefs.com story from the SPIE Defense + Commercial Sensing 2017 conference in Anaheim revealed new ways of detecting leaks in natural gas pipelines. Panelists from industry, academia, and government demonstrated how miniaturized sensing platforms, and the unmanned aerial vehicles (UAVs) hosting them, can improve the detection of hazardous gas leakage. What do you think? Will UAVs improve how we monitor the environment?

Is Your Data Acquisition System Prepared for Big Data?

Data acquisition systems are producing more analog data than ever before. This opportunity to uncover new insights comes at the risk of spending more time searching for and analyzing multiple data sets. Without proper data management, it is easy for important results to go unnoticed, causing repeated tests due to lost or undocumented data. Learn how proper metadata documentation, custom triggering, and implementing the right analysis technique help to save only the data you need to make informed decisions.

Method of Mapping Anomalies in Homogenous Material

This technology combines the SansEC circuit with a magnetic field reader to produce a spectroscopy readout.This innovation builds off of NASA Langley Research Center’s SansEC sensing system. SansEC is an open-circuit, resonant sensor that needs no electrical connections (thus the name SansEC or “without electrical connection”). This technology combines the SansEC circuit with a magnetic field reader to allow for detection of magnetic or electric field changes to produce a spectroscopy readout.

Controlled Deposition and Alignment of Carbon Nanotubes

CNTs are manipulated into specific orientations to create small, powerful, and flexible sensors.NASA Langley Research Center researchers are experts at producing carbon nanotube (CNT)-based sensors for structural health monitoring (SHM). The sensors can be embedded in structures of all geometries to monitor conditions both inside and at the surface of the structure to continuously sense changes. Having accumulated a body of knowledge on how to deposit and align CNTs, NASA is adept at manipulating the CNTs into specific orientations to create small, powerful, and flexible sensors. One of the sensors created by NASA is a highly flexible sensor for crack growth detection and strain field mapping that features a very dense and highly ordered array of single-walled CNTs. NASA is seeking companies that are interested in licensing technology or engaging NASA in joint research in the area of CNT sensors.

Active Remote Sensing Radiometer

This technology can be used for security screening and security imaging, as well as automotive navigation in dust and fog conditions where machine vision performs poorly.Millimeter-wave (mm-wave) imaging techniques are already a popular solution for imaging through dust and fog. While mm-wave offers excellent penetration to dust when compared with infrared or optical sensing, the longer wavelengths create many problems associated with the specular response of surfaces at mm-wave. Generally, at mm-wave, the geometry and orientation of the target object has a larger influence on captured contrast than material properties by several orders of magnitude. While these effects can be somewhat mitigated with a radar imager, there is still a large contrast dependence on beam-target angle, and images are still entirely derived from geometry instead of material compositions.
