Abstract

A sensor system comprises a signal sensor configured to receive a plurality of event signals for an event, a processing system coupled to the signal sensor and configured to process the plurality of event signals to determine if the event is a threat and responsive to determining that the event is a threat generate a threat message identifying the event, and an interface system coupled to the processing system and configured to transmit the threat message to a control system.

Claims

1. A security system comprising:

a barrier;

a sensor system mounted on a segment of the barrier and configured to receive an acceleration signal for an event, process an acceleration pattern contained in the acceleration signal to determine if the event is a threat, responsive to determining that the event is a threat generate and transmit a threat message identifying the event; and

a control system coupled to the sensor system by a communication link and configured to receive and process the threat message to determine a response to the event.

2. The security system of claim 1 further comprising a user interface system and wherein the response comprises a threat notification and wherein the control system is configured to transfer the threat notification to the user interface system and wherein the user interface system is configured to display the threat notification.

3. A method of operating a security system, the method comprising:

receiving an acceleration signal for an event into a sensor system coupled to a barrier;

in the sensor system, processing an acceleration pattern contained in the acceleration signal to determine if the event is a threat;

responsive to determining that the event is a threat generating and transmitting a threat message identifying the event from the sensor system to a control system; and

in the control system receiving and processing the threat message to determine a response to the event.

4. The method of claim 3 wherein the response comprises a threat notification and wherein the method further comprises transferring the threat notification from the control system to a user interface system and displaying the threat notification at the user interface system.

5. A sensor system comprising:

a signal sensor configured to receive an acceleration signal for an event;

a processing system coupled to the signal sensor and configured to process an acceleration pattern contained in the acceleration signal to determine if the event is a threat and responsive to determining that the event is a threat generate a threat message identifying the event; and

an interface system coupled to the processing system and configured to transmit the threat message to a control system.

6. The sensor system of claim 5 wherein the control system is remote from the sensor system.

7. A method of operating a sensor system comprising:

receiving an acceleration signal for an event;

processing an acceleration pattern contained in the acceleration signal to determine if the event is a threat;

generating a threat message identifying the event responsive to determining that the event is a threat; and

transmitting the threat message to a control system.

8. The method of claim 7 wherein the control system is remote from the sensor system.
