Reference letter from Areva NP

To whom it may concern,

Recently we evaluated the new ECX technology developed by Crystal Instruments Corporation. We believe that the capability of this embedded platform is innovative, unique and practically useful. The concept that combines the multiple functional measurements into the same handheld unit and the special technology that allows the system taking the measurements in a very wide dynamic range are very powerful. We are particularly confident that the ECX technology can be successfully used in motoring monitoring and testing applications.
