Title:
GROUND LEVEL PRESSURE SENSING DEVICE AND SYSTEM FOR ALARM SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2009/018833
Kind Code:
A2
Abstract:
The subject matter of the invention is a pressure-sensing device settled onto or under ground level. The device has a surface large enough for a human being stepping onto and contains an electric switch can be connected to an alarm system as a sensor. The pressure sensing devices can be connected to each other to form a large dimension sensor. Field of usage: police, military and border guard. Camouflage is advantageous e.g: placing under a mat or under a layer of soil.

CLAIMS

- the idea of designing units functioned as a power switch but at large way and put at the surface level and worked when anyone stand on it and connected with a main alarming device. - The idea of designing units functioned as a power switch look like a stair and worked when anyone stand on it and connected with a main alarming device. - The idea of camouflage and conceal of the previous units to be like the surrounding environment. - The idea of making one alarming device and multiplying the power switch even to a distance of about lkm square.- Protecting the previous method of manufacturing or any method or raw that perform the same goal.

Description:

Borders and Important Facilities Guard

Technical Field

Systems of Guarding of the Borders Background Art

Most of borders guard systems depends on the barbed wires and what is like it and that system allows to infiltrate but as for this system close all gaps before the insiders across the borders and I think there are not any previous devise that could perform the same object at this aspect especially this new system is able to protect a whole city from its all sides. The problem of the previous devices

Most of borders guard systems depend on the barbed wires, wall and so on that easing either to make a hole or dig a tunnel under it that make it easy to across it by night and away from the borders guards eyes. The New In the Invention Object

1- Invention of units that functioned as power switch for main alarming device that put in guarding tower on the borders.

These units put on the land surface level next to each other along the borders line and covered with material that look like the surrounding land.

These units work when anyone stands on it and connect the power circle to the alarming device across main wire under the land. - 1 used a cheap price material such as ( wooden board that carries the good on the ships) that makes the invention can be applied with out any financial costs on the burden of the state beside the speed and easing to dismantle, installation and transporting. - Using the mental spiral coil in an inventive way inside these units that make them switch off the power circle after anyone pass on it.

And it installation on a distance of about 500m from the inside to prevent the insiders across the tunnels. - The conceal method of these units by making it at the land surface level and covering it with what looks like the natural land that makes it like a trap for any insiders through that the army can use this system in wars behind the enemies lines, to catch spies, destroyer and capture attacker and the soldier can make it by themselves to protect it privacy. - 1 designed smaller units of the same idea to protect the important facilities from inside that install on the stairs and look like the stairs to help the system of monitoring by camera and it is either mental or wooden according to the surrounding environment.

Disclosure of Invention

We put a small alarming device run of battery beside the guarding soldier on the borders and we pass under the land a wire its length about 500m from the position of that soldier. This wire have been connected every one meter with the inventive power switch that consists of units that units width about 100cm and with length of about 120cm and its height of about 15 cm put next to each other on the land surface level on a distance of about 500m from the borders line to the inside and along the line of the borders.

These units categorically look like the surrounding land where they are covered with a mix of sand, cement and coloring material according to the color of the land. Every unit of the previous units- consists of two components the lower component that fixed on it slice of rectangle iron and on it one of the connecting wire on its back holes that hang down mental spiral coil.

And the upper part of the component works as a cover also with it slices of rectangle mental have twisted edge functioned as pull dawn the mental spiral coil if anyone stands on the unit and with it the second connecting part of the circle. From the other side of the two component of the unit there are hinges that linked them together.

When these units put on the borders we make the side of the mental spiral coil in our direction then put wooden cover (or

mental in case of road) and it also look like the surrounding land and functioned as a bridge that increase the wide of the device that make it impossible to anyone to pass on it without connecting the circle and the alarming device start working. And to protect the important facilities from inside I designed small units that looks like stairs and it works by the same previous idea where we make a stair play as the lower component of the borders guard device and we cover it with another part of the same color of the stair and between the two pieces hinges and mental slices and so on, where anyone stand on this piece s/he actual stands on the power switch in the security manager room. The Using Method

After we prepare the aforementioned power units we put it at a distance of about 500m to cut the road before the insiders even across the tunnels and we connect the wires with the main wire that linked with the alarming device then covering the area of the device and put some real sands and land on it and concealing the device from its sides.

Consequently when the insider comes s/he does not see anything unusual so s/he keep on filtrating and by the time s/he touches the new device the cover descended down because of the lower mental spiral coil and the wires touch each other and connect the circle in the alarming device that sited in the guard position that leads to catch the insider who do not know how s/he was found.

This invention could be used in order to protect the energy, railway and oil pipelines.

By the same idea but in a minimized way we can protect the important facilities as we protect them form inside by installing the units that look like stairs.
