In an effort to improve nondestructive inspections (NDI), American Science & Technology (AST) is developing wireless capability for specific pieces of NDI equipment in the areas of eddy current and ultrasonic technologies. Traditionally, this equipment requires a cable connection from the host controller to the handheld probe. ASTÂ’s work would develop an attachment for the host controller as well as for the probe which would simulate the communication process achieved through a direct cable connection. This project is unique from other wireless adapters in that it would be specifically engineered to work with NDI equipment. Specific circuitry to drive NDI probes, high-speed wireless communication between controller and host, and integrated impedance-matching hardware would all be incorporated to ensure the most accurate representation of wired communication. The major advantage to this system would be its ability to be incorporated into pre-existing equipment without the need for purchase of new, modified NDI equipment offering a cost-savings aspect over other approaches.
