Automated Inspection
The Pan-AM Flight 103 tragedy announced the need for improved airport explosives detection technology. The founding team at InVision Technologies, Inc., including Phillip Yeager, responded by developing the first FAA-approved explosives detection system. The CTX system was the most widely used, TSA-certified explosives detection system (EDS) in the world.
The system uses technology derived from medical Computed Tomography (CT) to help locate and identify explosive devices concealed in checked baggage.
When InVision Technologies, Inc. set out to solve the urgent problem of airport luggage inspection, the company required engineers capable of quickly grasping complex technology, optimizing algorithms and cheerfully contributing long hours of effort. Phillip Yeager was a key technical team leader in the startup.
At InVision Technologies, Inc., Yeager performed computer system and software design for the startup industrial Computer Assisted Tomography (CT) scanner manufacturer. He implemented the real-time subsystems (data acquisition, machine control, operator controls) on an embedded RTOS. Yeager also implemented the CT image reconstruction subsystem. The result of this work was an optimized computer system and software that tripled pre-existing CT scanner throughput. Software for these projects was written in C.
