Maryland inventor develops patent for threat detection

A bioengineer at the Edgewood Chemical Biological Center at the Aberdeen Proving Ground recently developed a patent for a tactical chemical biological threat detection system.

Ravinder P. Lall, who studied biochemistry at the University of Chicago, the Indian Institute of Technology and the Illinois Institute of Technology, developed patent number 8,294,102. The patent relates to a threat detection system for enhancing chemical and biological threat detection in atmospheric air, standard air and at atmospheric range at various time intervals.

The patent uses the concept of quantitative monitoring of atmospheric air to detect chemical and biological threats. It also measures the quantitative correlations and ratios in differential air changes to detect active and passive chemical and biological infrared electromagnetic radiation.

The system would use electro-optics and the reference chemical and biological IR EM radiation signatures to detect the absorption, emission and scattering of signatures for comparison.

In the patent application, Lall said that the potential of the threat detection model is demonstrated in its ability to measure the intensity of electromagnetic energy for specific wavelength ranges of biological and chemical agents with natural and artificial sources of light. The system is suited for continuous chemical and biological threat monitoring.

The application notes that Lall has been granted rights in the invention in return for a non-exclusive, royalty-free, irrevocable license to the U.S. government to grant licenses for all governmental purposes.
