Millimeter wave technology offers 'pat down' security without the pat

SAN DIEGO, CA. July 4,2006- Sago Systems, Inc. has introduced the world’s first hand held millimeter wave imaging system, the aPat. The aPat finds concealed contraband such as guns, knives, drugs and explosives on individuals without compromising personal privacy or dignity.

The aPat uses passive imaging of millimeter waves to find metallic and non-metallic objects through clothes, including thick jackets or multiple heavy layers. The unit is completely safe and does not use x-ray or microwave radiation. Millimeter waves have wavelengths 1,000 times longer than infrared and accurately show scene temperatures. They are naturally emitted from all objects.

The aPat is easy to use and requires no special training or installation. It is battery operated and it works indoors and outdoors, day and night. The aPat provides reliable detection of explosives, metal guns and knives, and ceramic weapons. It is wireless-enabled and automatically stores images to a central server for audit purposes. The aPat’s full color, 800 x 480-pixel, 5” LCD clearly shows possible threats such that they can easily be recognized.

Sago also manufactures the ST-150, a standoff detector that can be deployed at mobile checkpoints or building entrances, as a perimeter security device or as a covert contraband detection system. The ST-150 is user-friendly and designed for mobility. It is lightweight and transportable, rapidly sending data to a local or remote command center.

Sago Systems, Inc., a subsidiary of Trex Enterprises Corporation, is the pioneer of passive millimeter wave imaging technology. Sago is headquartered in San Diego, California. Sago develops, manufactures and sells state-of-the-art passive millimeter-wave imaging systems for security applications.
