Acoustic emission intrusion detector (Engineering Materials)

Miscellaneous ·
OSTI ID:5747569

A sensitive acoustic emission device has been developed that will detect forcible entry through block or tile walls, concrete floors, or steel-reinforced concrete vault walls. A small, low-powered processor was designed to convert the output of a transducer into a relay signal for use with a supervised alarm loop. The nuisance alarm rate of the detector was extremely low during its initial eighteen months of use. Power requirements for the processor were minimized through the use of complementary metal oxide semiconductor (CMOS) amplifiers and integrated circuits.
