Các xuất bản


Air Traffic Analysis System (ATAS) was a patent I was awarded in 2005. It used ground systems that interfaced with all forms of air traffic control, including military, civilian, and ships, to come up with a more comprehensive picture that may not have been realized without several sources. It also had data such as flight plans and was able to identify national emergency trends such as 9/11 style terrorism and immediately notify decision makers at high levels within the government.
