Each month, NTB highlights tech briefs related to a particular area of technology in a special section called Technology Focus. Here are some of the technologies featured in the December issue focus on Data Acquisition.

- Monitoring By Use of Clusters of Sensor-Data Vectors

NASA's Ames Research Center developed the inductive monitoring system (IMS) of computer hardware and software for automated monitoring of the performance, operational condition, physical integrity, and other aspects of the "health" of an engineering system such as an industrial process line. The system has a smaller computational burden than previous systems, and there is no need for abnormal-condition sensor data in order to train the IMS to recognize abnormal conditions. (Page 25)

- Processing Satellite Imagery to Detect Waste Tire Piles

NASA Ames has also developed a method for processing commercially available satellite spectral imagery to identify and map waste tire piles in California. It uses image-processing and georeferencing software to develop a model that distinguishes between tire piles and other objects. It reduces the time necessary to survey a region for tire sites, enabling more time for site remediation. (Page 26)
