4. AL Introducing AVIAN The AVIAN Heartbeat Detector quickly and efficiently detects the presence of persons hidden inside vehicles of any variety Using data from special sensors the AVIAN locates the shock wave generated by a human s beating heart which couples to any surface or object with which the body is in contact The AVIAN collects data and analyzes it using advanced signal processing algorithms to detect a hidden person in less than one minute The system consists of an industrial grade personal computer standard PC operating system custom AVIAN software a touch screen monitor and sensors attached to retractable cables The operator places the sensors on the vehicle then uses the touch screen to initiate a vehicle inspection The processed data provide the operator with a PASS or SEARCH indication The completed test can take as little as 23 seconds after the test is initiated e System Components The hardware system consists of the following ndustrial grade computer Data acquisition signal conditioning software and hardware Geophone sensors Optional sensor cabinet containing reel mounted cables The system requires 90 132 V AC or 180 264 V AC 50 60 Hz and consumes 70 VA of power AVIAN is CE approved Getting Started Starting AVIAN As shipped the system is configured to automatically start with the AVIAN software upon power up To power up the system depress the black button to the ON position top rear I
