Abstract
Abstract Methods of detecting the presence of concealed weapons and determining the type of weapons with a greater degree of certainty and reliability. The method involves tagging of the weapon with a radioactive marking that produces penetrative radiation, and providing radiation detectors at entrances to commercial and private residences, airlines, vehicles and other places. According to a preferred method, the tagging or marking of the weapon is in a form of a digital coding; and a different common coding is applied to each different kind of weapon. For example, hand guns receive a common code of one type; knives a different code; explosives a third different code, and the like.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
A method of identifying and detecting a weapon that is concealed from view comprising the steps of: incorporating a radioactive marking material in the form of a coding in the weapon in a concealed manner that produces a non-visible code of radiation of sufficient intensity as to be detectable at a distance from the concealed weapon, detecting such code of radiations at each location where it is desired to detect such weapon, such a detector being provided at locations including one of entranceways into rooms, vehicles, places of entertainment, windows, and other entrances and exits.
Claim 2
Independent Claim
95 words
A method of identifying and detecting a weapon that is concealed from view comprising the steps of: incorporating a radioactive marking material in the form of a coding in the weapon in a concealed manner that produces a non-visible code of radiation of sufficient intensity as to be detectable at a distance from the concealed weapon, detecting such code of radiations at each location where it is desired to detect such weapon, such a detector being provided at locations including one of entranceways into rooms, vehicles, places of entertainment, windows, and other entrances and exits.
Claim 3
Dependent Claim
33 words
In the method of claim 1, each different type of weapon being marked with a distinctively different code of radiation to distinguish the type of weapon being detected from weapons of other types.
Claim 4
Dependent Claim
20 words
In the method of claim 1, the additional step of indicating at said detector the type of weapon being detected.
Claim 5
Dependent Claim
54 words
In the method of claim 1, the marking material being incorporated in a manner to produce a digital code of penetrative radiation with weapons of the same type having the same code and weapons of different type having a different code, whereby upon detection, the type of weapon that is concealed may be known.
Claim 6
Dependent Claim
27 words
In the method of claim 1, the step of incorporating the marking material comprising integrally incorporating such marking in the weapon to deter obliteration of the marking.
Claim 7
Dependent Claim
24 words
In the method of claim 1, the step of incorporating the marking material comprising applying the material as a non-visible coating on the weapon.
Claim 8
Dependent Claim
21 words
In the method of claim 1, the coding being provided by applying a plurality of different radio-active materials to the weapon.
Claim 9
Dependent Claim
19 words
In the method of claim 1, the coding being a different digital code for each different kind of weapon.
Claim 10
Dependent Claim
19 words
In the method of claim 1, the coding being a different analog pattern for each different kind of weapon.
Claim 11
Dependent Claim
34 words
In the method of claim 1, the detecting of said code being performed by a portable detector that can be moved relative to the concealed weapon to determine the location of the concealed weapon.
