Abstract: A fortified gate system and locking mechanism is disclosed which utilizes spring loaded locking mechanisms, triggered by the impact of an object such as a vehicle, to interlock a gate, a brace, and fortified anchoring devices. This interconnected structure forms an energy absorbing, impenetrable barrier. Because the gate system functions as a normal gate until an instance of attempted crashing entry, it provides reasonable accessibility while maintaining a high level of security.

Abstract: A security system includes an entry monitoring sensor for detecting movement into a first space, a first area monitoring sensor for detecting occupancy in the first space, at least one area monitoring sensor for detecting occupancy in at least one space adjacent the first space. The system further includes a timing device for measuring a first time period in response to actuation of the entry sensor and for measuring a second time period in response to the actuation of the first area sensor during the first time period. An alarm device indicates any suspicious occupancy at the expiration of the second time period in the absence of detection of occupancy by at least one of the area sensors for detecting occupancy in at least one space adjacent the first space.

Abstract: An anomaly detection system (10) and method including; a plurality of sensor means (12) for providing an output representative of the current operational environment of the subject premises. There are means (14), responsive to the output, for translating the output to a signal, and control means (18) for statistically defining the normal operational parameters of the subject premises.Stochastic means (16), responsive to the output representatives of the current operational environment periodically adjust the definition of the normal operational parameters of the subject premises. There are processor means (20) for comparing the output representative of the current operational environment with the updated definition of the normal operational parameters of the subject premises, and for detecting a deviation therebetween.
