Claims:Briefly, the claims are as follows:-
1. The technology to deter suicide bomber comprises of - two gates located at the entry and exit of the wide gate or passage, a x-ray scanning machine located inside the wide gate.
The safety measure according to claim (1) where we will use a wide entry gate and engage a similar X-ray machine that is used in airport, for online luggage X-ray scanning for checked baggage moving in belt conveyor. If any doubtful scan result comes on the screen, the X-ray scanning gate will close. The security personnel sitting at a distance in a separate location will study the scanned picture thoroughly and will decide to open the X-ray scanner gate or will ask the doubtful person to open up his/her clothing for thorough check. This little machine scanner can save disaster happening due to suicide bomb.

2. A dual frequency ultrasonic beam and Colour Doppler ultrasonic beam to detect hidden weapon using the same principle as is being used by ships to survey sea-beds.
The safety measure according to claim (2) is that we will use dual frequency ultrasonic beam to an approaching person from a distance (say 50 ft.). The high frequency will penetrate the clothes and will return from body skin, this low frequency will reflect from any hidden metal or bomb. If we use Colour Doppler ultrasonic beam, the remotely stationed security person can observe the details of arms or bomb that a suicide bomber/terrorist might be carrying from the difference of distance between reflected surfaces. , Description:FIELD OF THE INVENTION
(A) The present invention relates to the safety of people from any suicide bomber/terrorist attack in any crowded place such as-- international airports, VIP events or any other important hotels/market place, crowded political meetings etc. Entry gate where suicide bomber is entering can be monitored from a distant location. Here, we will use a wide entry gate and engage a similar X-ray machine that is used in airport, for online luggage X-ray scanning for checked baggage moving on belt conveyor. If any doubtful scan result comes on the screen, the X-ray scanning gate will close. The security personnel sitting at a distance in a separate location will study the scanned picture thoroughly and will close the entry gate and will decide to open the X-ray scanner gate or will ask the doubtful person to open up his/her clothing for thorough check. This little machine scanner can save disaster happening due to suicide bomber.
(B) We also use dual frequency ultrasonic beam (A dual frequency ultrasonic machine i.e. a dual frequency Eco-Sounder is a standard equipment used by any pilot ship for helping dredging ship. Through this dual frequency ultrasonic beam, the surface of sea-bed and any material lying on sea-bed e.g stone, sludge, metal etc. can be seen/detected separately) to an approaching person from a distance (say 50 ft.). The high frequency will penetrate the body covered with clothes, low frequency will reflect from any hidden metal or bomb. If we use Colour Doppler ultrasonic beam, the remotely stationed security person can observe the details of arms or bomb that a suicide bomber/terrorist might be carrying. It can be used from police van/ from podium where a VIP is sitting/ in a crowded place from standalone equipments etc.
In a crowded road an armed car carrying such dual frequency Colour Doppler ultrasonic beam equipment can scan a wide area and detect any person with hidden suicide bomb jacket/revolver etc. Colour Doppler ultrasonic beam, the remotely stationed security person can observe the details of arms or bomb that a suicide bomber/terrorist might be carrying from the reflection of two frequencies. If no hidden thing is there both beam will reflect from same distance. If some thing hidden is there, reflection will show two distances from the same person. Difference of distance is the width of the hidden weapon/ bomb.
DESCRIPTION OF THE RELATED ART
A number of safety equipments and apparatus have been designed in the past such as Patent Publication Number WO2006071198A1 which was about Remote explosives/bomb detection system with proximity sensors and the Patent Publication Number US20080083320 which was about System, Method, and Apparatus for Countering Improvised Explosive Devices (IED). However, none of these safety equipments and mechanism provide for a wide gate which will detect the person entering any important places from a safe distant locations so that the person carrying weapon cannot harm the security people. This will also ensure the security and safety of the person monitoring the scanning machine. Use of dual frequency ultrasonic beam and Colour Doppler ultrasonic beam to observe the details of arms or bombs that a suicide bomber/terrorist might be carrying hidden beneath his shirt/ jacket will be detected.

BACKGROUND OF THE INVENTION
It is believed that the prior articles consists of the following publications: U.S Pat. No. US6113343 (Goldenberg; Andrew, 5 Sep 2000); U.S Pat. No. US20040232054 (Brown Betty J, 25 Nov 2004); U.S Pat. No. US20040237761 (Gabriel Edwin Z., 2 Dec 2004)
SUMMARY OF THE INVENTIONS
(A) It is one of the prime objective of the present invention to provide a wide entry gate and engage a similar X-ray machine that is used in airport, for online luggage X-ray scanning for checked baggage moving in belt conveyor. If any doubtful scan result comes on the screen, the X-ray scanning gate will close. The security personnel sitting at a distance in a separate location will study the scanned picture thoroughly and will decide to open the X-ray scanner gate or will ask the doubtful person to open up his/her clothing for thorough check. This little machine scanner can save disaster happening due to suicide bomb.
(B) We use dual frequency ultrasonic beam to an approaching person from a distance (say 50 ft.). The high frequency will penetrate the body covered with clothes, low frequency will reflect from any hidden metal or bomb. If we use Colour Doppler ultrasonic beam, the remotely stationed security person can observe the details of arms or bomb that a suicide bomber/terrorist might be carrying from the reflection of two frequencies. If no hidden thing is there both beam will reflect from same distance. If some thing hidden is there, reflection will show two distances from the same person. Difference of distance is the width of the hidden weapon/ bomb.

In a crowded road or an armed car carrying such dual frequency Colour Doppler ultrasonic beam machine can scan a wide area and detect any person with hidden suicide bomb jacket/revolver etc.
BRIEF DESCRIPTION OF THE DRAWING
The invention may be understood upon reading of the following detailed description of non-limiting exemplary embodiments thereof, with reference to the following drawings, in which:
SUGGESTION A :
FIG. 1 is a front-view of the wide entry gate which simply shows the entry gate and the exit gate which can be controlled i.e. opened or closed remotely, a wide body X-ray scanner which is located inside the wide gate to scan the persons entering the gate.
SUGGESTION B :
We are also using dual frequency ultrasonic beam to an approaching person from a distance (say 50 ft.). The high frequency will penetrate the body covered with clothes, low frequency will reflect from any hidden metal or bomb. If we use colour Doppler ultrasonic beam, the remotely stationed security person can observe the details of arms or bomb that a suicide bomber/terrorist might be carrying.
In a crowded road or unknown to public an armed car carrying such dual frequency colour Doppler ultrasonic beam throwing equipment which can scan a wide area and detect any person with hidden suicide bomb jacket/revolver etc.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION
(A) With reference to FIG. 1, which is the front view of the wide entry gate showing the entry gate 1 which can be controlled i.e. opened or closed from a remote location. It also shows the exit gate 2 which can also be controlled i.e. opened or closed from a remote location. Now inside the wide entry gate is located a wide body X-ray scanner 3 which is used by the security person sitting at a distance in a separate location who will study the scanned picture thoroughly and will decide to open the X-ray scanner gate or will ask the doubtful person to open up his/her clothing for thorough check. This little machine scanner can save disaster happening due to suicide bomb.
(B) We can also use the dual frequency ultrasonic beam or colour Doppler ultrasonic beam to an approaching person from a distance (say 50 ft.). The high frequency will penetrate the body covered with clothes, low frequency will reflect from any hidden metal or bomb. Both frequency will reflect back. Difference of distance between two reflection will detect if any hidden bomb/ weapon is being carried. If nothing is hidden, both reflection will show the same distance.
