A seismic and pressure wave sensor adapted to be buried in the earth to detect disturbances comprises a deformable tube containing an incompressible liquid in which a force-responsive transducer is immersed. The output of the transducer is an alternating signal having spectral components corresponding to both seismic (10-100 Hz) and pressure (< 1 Hz ...

Intrusion Prevention and Detection Systems
2009With the increasing importance of information systems in today’s complex and global economy, it has become mission and business critical to defend those information systems from attack and compromise by any number of adversaries. Intrusion prevention and detection systems are critical components in the defender’s arsenal and take on a number of ...
