PROTECTING MILITARY PERIMETERS FROM APPROACHING HUMAN AND VEHICLE USING BIOLOGICALLY REALISTIC NEURAL NETWORK
First Claim
1. A security system for protecting perimeters from an approaching human or vehicle comprising:
- a seismic sensor system configured to sense ground vibration caused by human footsteps, a vehicle, quadrupedal animal footsteps, and other activity; and
a trained biologically realistic neural network system configured to receive information indicative of the ground vibration sensed by the sensor system and to discriminate between ground vibration caused by each of the following based on this information;
human footsteps;
a vehicle;
quadrupedal animal footsteps; and
other activity.

Abstract
An approaching human threat or vehicle, such as a suicide bomber nearing a secured zone such as a military base, may be detected and classified. A vibration recognition system may detect a systematic vibration event. The entity might be a medium, human, animal, or a passenger vehicle. The system may discriminate between such an event and a background or other vibration event, such as a falling tree limb. A seismic sensor may be employed to detect vibrations generated by footsteps and a vehicle. Seismic waves may be processed locally where the sensor is located. The system may wirelessly communicate with a remote command center. Temporal features of the vibration signals may be modeled by a Dynamic Synapse Neural Network (DSNN) with good false recognition rates. The models may reject quadrupedal animal footsteps.
