Security barriers with automated reconnaissance
First Claim
1. An intrusion delaying barrier comprising:
- a. a primary structure selected from the group consisting of i) a steel beam supported by cross-bucks standing on top of the ground and ii) a row of concrete blocks sitting on top of the ground, wherein the row of concrete blocks is bound end-against-end by a chain of steel tie-bars; and
b. a secondary structure selected from the group consisting of a chain link fence, a welded mesh fence, and a wire fence;
wherein a majority of weight of the secondary structure is supported by the primary structure; and
wherein neither the primary structure nor the secondary structure is planted into the ground.

Abstract
An intrusion delaying barrier includes primary and secondary physical structures and can be instrumented with multiple sensors incorporated into an electronic monitoring and alarm system. Such an instrumented intrusion delaying barrier may be used as a perimeter intrusion defense and assessment system (PIDAS). Problems with not providing effective delay to breaches by intentional intruders and/or terrorists who would otherwise evade detection are solved by attaching the secondary structures to the primary structure, and attaching at least some of the sensors to the secondary structures. By having multiple sensors of various types physically interconnected serves to enable sensors on different parts of the overall structure to respond to common disturbances and thereby provide effective corroboration that a disturbance is not merely a nuisance or false alarm. Use of a machine learning network such as a neural network exploits such corroboration.

11. An intrusion delaying barrier comprising:
-
a. a contiguous series of interconnected steel beams that help to form a dividing line between a secure area of ground on one side of the beams and a less secure side on the other side of the beams; b. multiple sensors; c. multiple types of mechanical support structures each connecting one of the multiple sensors to the chain of interconnected steel beams; d. an alarm status indicator; and e. a computer in communication with both the multiple sensors and the alarm status indicator; wherein the multiple sensors include at least three different types of sensors based on different transducer principles; and wherein a status of the alarm status indicator is controlled by the computer to be a function of degree of correlation among at least two of the at least three different types of sensors in sensing at least an intrusion attempt. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method of configuring a security barrier, the security barrier comprising both a physical barrier to delay or stop intruders and a system of sensors useful to detect intrusion attempts, the method comprising steps of:
-
a. installing the physical barrier; b. installing the sensors to the physical barrier; c. installing communication media for communication between the sensors and an alarm annunciator; d. installing additional communication media for communication between at least one computer and two or more of the sensors; and e. providing the at least one computer with instructions to execute a machine learning algorithm to transform sensor outputs into alarm outputs for the alarm annunciator; wherein no concrete or steel element of the physical barrier is buried in the ground. - View Dependent Claims (20, 21)
