Abstract
Abstract A method and system for detecting stolen articles such as by shoplifting. Articles in a store and the like are sprayed with a non-toxic, humanly undetectable aerosol which is subject, being highly aromatic in nature, to detection by a sensing device. In removing the treated article a detection area or zone from the store must be passed and if unauthorized or unapproved removal of the article is attempted an indicator or alarm is activated by detection of the aerosol, resulting in apprehension of the article carrier. If the article is paid for or removal from the premises is otherwise authorized, then when passing through an authorizing area such as a checkout counter, the sensible odor can be neutralized or rendered passive or an additional neutralizing agent or means can be applied to the article, either method of which will serve to prevent activation of the detection device.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
89 words
A method of detecting attempted unauthorized removal of articles from premises of an establishment including the steps of: A. applying an olfactronic sensible material to the articles; B. establishing an olfactronic detection zone requiring passage therethrough of the so marked articles for removal from the premises; C. discriminately detecting existent olfactronic emissions from the so marked articles during passage through the detection zone; and D. selectively activating indicating means by the presence or absence of selected detected olfactronic emissions to indicate attempted unauthorized removal of articles from the premises.
Claim 2
Independent Claim
89 words
A method of detecting attempted unauthorized removal of articles from premises of an establishment including the steps of: A. applying an olfactronic sensible material to the articles; B. establishing an olfactronic detection zone requiring passage therethrough of the so marked articles for removal from the premises; C. discriminately detecting existent olfactronic emissions from the so marked articles during passage through the detection zone; and D. selectively activating indicating means by the presence or absence of selected detected olfactronic emissions to indicate attempted unauthorized removal of articles from the premises.
Claim 3
Dependent Claim
26 words
A method as claimed in claim 1 wherein said olfactronic material consists of odorifeRous materials normally humanly undetectable and in the nature of non-toxic Freon compounds.
Claim 4
Dependent Claim
26 words
A method as claimed in claim 2 including encapsulating the olfactronic material utilizing a microencapsulation technique adapted for time release subsequent to application to the articles.
Claim 5
Dependent Claim
28 words
A method as claimed in claim 1 including the step of neutralizing the olfactronic sensible material applied to the articles to indicate authorized removal thereof from the premises.
Claim 6
Dependent Claim
36 words
A method as claimed in claim 4, wherein an agent - remove agent is applied to the article at the time of authorized removal whereby any agent detected leaving the building indicates unauthorized article removal attempt.
Claim 7
Dependent Claim
25 words
A method as claimed in claim 4 including applying a masking agent to the first applied olfactronic sensible material for indicating authorization of article removal.
Claim 8
Dependent Claim
60 words
A method as claimed in claim 1 including applying two agents having olfactronic sensible capabilities wherein one is applied to articles as normally stored on the premises and a second is applied at a time of article removal authorization whereby if only a single agent appears on an article at the detection zone an indication of attempted unauthorized removal results.
Claim 9
Dependent Claim
16 words
A method as claimed in claim 5 including removing the agent by application of ultraviolet light.
Claim 10
Dependent Claim
29 words
A method as claimed in claim 5 wherein the detection agent is encapsulated and subsequently removing the agent by means of adhesives, magnetics or by bursting with ultrasonic vibrations.
Claim 11
Dependent Claim
33 words
A method as claimed in claim 7 wherein the secondarily applied agent can consist of a label marked by a short life agent, a stamp or a sales slip attached to the article.
Claim 12
Dependent Claim
23 words
A method as claimed in claim 1 wherein detection of the olfactronic emissions is accomplished by an electron capture type of gas chromatograph.
