Sensor for detecting human intruders, and security system
First Claim
1. A dual-modality sensor for detecting human intruders to a secure setting, comprising:
- a seismic sensor for detecting and measuring seismic disturbances;
an active acoustic sensor for acquiring an acoustic signature relating to a detected seismic disturbance; and
a processor for processing and correlating the measured seismic disturbance and the active acoustic signature to verify a presence of a human characteristic therein, and for generating a human intruder alarm signal where said human characteristic presence is verified.

Abstract
A dual-modality sensor for detecting a presence of a human intruder within a secure setting includes a seismic sensor for acquiring a seismic signature of a disturbance, and includes an active acoustic sensor to acquire an acoustic signature of the disturbance. A system processor is electrically connected to the seismic and active acoustic sensors to receive and process the seismic and acoustic signatures, and generate an alarm signal when the disturbance is determined to come from a human intruder. Also included is an antenna and/or hard-wire connection arranged for communicating the alarm signal. The dual-modality sensor is arranged in a sensor housing constructed to contact a surface of the secure setting. The sensor may include a battery or other means for providing electrical power.

18. A security system for protecting a secure setting, comprising:
-
a command center including a command center processor; at least one dual-modality sensor in communication with the command center for detecting a presence of a human intruder within the secure setting, comprising; a seismic sensor for detecting and measuring a seismic disturbance; an active acoustic sensor for acquiring an acoustic signature of the detected seismic disturbance; and a sensor processor for processing and correlating the measured seismic disturbance and acoustic signature and generating an alarm signal if a correlation is found by said processing indicative of a human gait; and means for communicating with the at least one dual-modality sensor. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
