Abstract

Electrical activity of the brain and heart of a patrolling guard (2) are continuously transmitted to the monitoring station (5) where the signals are decoded and checked for any descrepancies. An alarm is generated by the monitoring equipment if a guard's life indicating activity exceeds prescribed limits or differs from a built up signature of each guard's bioelectrical activity. The scale of the alarm depends on the type of discrepancy detected - ranging from lack of alertness on the part of the guard to complete cessation of the guard's life indications. <IMAGE>

Description

High security guard monitor The principle of this invention is to monitor patrolling guards' life indicating activity and generate an alarm if the activity becomes unusual.

In situations where high security is required around sensitive areas the current methods are to employ pairs of guards patrolling the perimeter and access points. Regular checks are made and the guards report in regularly. But security is easily jeatkdised by the guards not being up to the required level of alertness, or being incapacitated by intruders before an alarm can be raised. This usually happens if the guards are killed quietly and then replaced by false guards, etc to permit the intruders to penetrate further into the sensitive area.

The possiblity of this happening can be reduced by continuously monitoring the state of the guards' bioelectrical activity and triggering an alarm if this changes. So making it virtually impossible for intruders to gain violent access to an area without being detected. This is provided there are sufficient guards to survey the perimeter and also the installation to prevent undetected access. Additionally, by logging a signature of each guard's bioelectrical activity, any attempt to substitute a false signal for the genuine one would be difficult.

The principle is to transmit the electrical activity of the heart and brain of each guard to a monitor. The monitor processes the electrical activity signal of each guard and generates an alert if it detects that the activity outside the criteria set for each guard. That is, if a guard is knocked unconscious, the brain activity will change from a normal mixture of alpha and beta waves to a predominance of delta waves. Similarly, if the guard is wounded the heart and brain activity will change. Should the guard be killed, the elctrical activity of the brain and heart will change rapidly and then stop.

The monitoring station, consisting of a computer to analyse the signals of each guard and equipment to interface it to the received signals, can be arranged to look for the usual signature within the signal of each guard and generate an alert if any of the signals become unacceptable.

With an adequate number of guards to patrol the area to be protected against intruders, any incursions would be quickly detected. The alarm could also be automatically propAgated to other stations to enable extra help to be summoned.

Figure 1 shows the principle in use. The heart and brain electrical activity of each guard is amplified, encoded, and relayed to the monitoring station. The monitoring station checks that the signal is continuous, is within prescribed limits, etc. The monitoring station would consist of a computer analysing the signals received via a multichannel radio receiver. The computer would log each guard onto duty, and while performing his duties, and then check the guard off duty and the replacement on duty. If the activity of a guard became unusual, the monitor would generate an alarm and indicate the last known position of the guard to other nearby guards. <img class="EMIRef" id="027180022-00020001" />

Claims (3)

  1. <img class="EMIRef" id="027180023-00040001" />
    Claims 1. Electrical activity of the biological entity acting as a guard is built up to form a signature of normal activity and any discrepancies from this are used to generate an alarm.
  2. 2. The above claim in which the guard's bioelectrical activity is relayed to a monitoring station which may be a network of stations specifically for the purpose of detecting unwanted intrusion into a sensitive installation.
  3. 3. The above two claims applied with the condition that some of the monitoring is done on the guard and relayed to the monitoring station or all the analysis is done at the monitoring station or stations.
