3754223 Intruder detection system, Shmuel Shtrikman (Yeda R&D),Aug 21 1973, 340/551 - magnetic cable RE29019 Intruder detection system, Shmuel Shtrikman (Yeda R&D), Oct 26, 1976, 340/258C; 340/381 - Pathfinder Seismic Intrusion Detection System is specifically optimized for Defense, Border Security, Critical Infrastructure, and Consumer applications. Best Seismic Intrusion Detection System against all threats. [1] An array of radars is developed as a standoff sensor for use in seismic/elastic mine detection systems. The array consists of N radar sensors which operate independently to sense the displacement of the surface of Earth due to elastic waves propagating in Earth.

Seismic detection system based on ZETSENSOR series products has been developed for the prevention of risks relating to the use, maintenance, control and emergency operation of elevators that have been exposed to seismic impacts. The GM760 seismic detector is the all-purpose unit in the Vanderbilt`s GM7xx- series. It is perfectly suited for applications on steel, concrete as well as lightweight synthetic materials. Intelligent signal processing enables the level of detection sensitivity to be custom-set, thereby reducing the risk of false alarms.

7. The seismic detection system deiined in claim 6, wherein said seismic mirror means includes a suitable quantity of liquid mercury. In one preferred embodiment, a seismic detection and control circuit is connected with an external security or fire system capable of activating alarms, releasing doors, initiating emergency calls and other control functions. In the event of seismic activity, the detection circuit determines whether an explosion or earthquake has occurred.
