X-Change Receives Order for SAW-Based Delay Lines and Temperature Sensors Study.

DALLAS -- X-Change Corporation's (OTCBB:XCHC) wholly owned subsidiary, AirGATE Technologies, Inc., has received from NASA - Johnson Space Center a purchase order for a study of surface acoustic wave ("SAW") delay lines and temperature sensors. E[acute accent]The study is expected to lead to further development of custom SAW delay lines and temperature sensors. Today's news follows an August 3 release announcing AirGATE's sale of a (SAW) development system to NASA - Johnson Space Center. E[acute accent]The basic SAW device is a thin metal film structure deposited on top of a piezoelectric crystal substrate with no power supplies. It reflects radio signal based on the pattern etched onto its surface. These reflections can be de-coded into data. In addition to RFID, SAW devices make very accurate temperature sensors. The devices work well in harsh environments as well as in the presence of liquid and metals. E[acute accent]"We are extremely pleased by this expanding interest in our SAW systems and additional commitment from NASA - Johnson Space Center," stated Mike Sheriff, president and chief executive of X-Change Corporation. E[acute accent]"Currently," added Mr. Sheriff, "X-Change is positioned to ship SAW RFID tags and reader systems in volume, in addition to custom SAW designs and applications." This, he said, is the result of an exclusive national agreement for sale and support of SAW RFID systems signed in January with Carinthian Tech Research, a leading Austria-based developer of SAW RFID devices and technology. E[acute accent]X-Change Corporation, through its wholly owned subsidiary, AirGATE Technologies, Inc. is a leader in unique, vertical market applications utilizing RFID and wireless, intelligent, sensor technology. AirGATE Technologies, a full-solution company, handles business assessment, technology selection, including proprietary AirGATE technology, integration and support.
