  • Intrusion detection system
    Patent number: 4527150
    Abstract: An underground taut wire intrusion detection system includes a sensor wire enclosed within a conduit adapted to be buried in the ground, the conduit being sufficiently rigid so as to be collapse-resistant when buried in the ground, but being sufficiently flexible in its length such that when disturbed by an attempted intruder the disturbance is transferred to the sensor wire to cause it to actuate a detector.
