FR2700617A1 - Compound to assist detection and identification of articles - Google Patents

Abstract

The compound, such as a varnish, ink, paint or other coating material is designed to be magnetisable and applied to an article by silk screen printing or other means. The compound can be applied, for example, in the form of printed symbols adjacent to a bar code, in or under a label or in some other location on an article, and is designed to be detected by a fixed or portable device. The compound can, if necessary, be demagnetised, e.g. when it is used on articles of clothing or other wares on sale in a show and is used as proof of purchase, preventing a person from taking something out of the shop which has not been paid for.

Description

DESCRIPTION:
The state of the art in terms of anti-theft for objects placed within reach of the public at points of sale, shows that thieves easily turn devices and it is therefore important to find a mode, method and device making it possible to remedy to this state of affairs. This is what the present invention proposes which innovates in this sense, by modifying the composition of varnishes, inks and magnetic paints studied to memorize the various messages of bank cards and other neighboring devices and methods, to render said varnishes, ink or paint. , applicable in texts, shapes, impregnations of fabrics and others, leathers7 corks and neighboring supports, as well as in mixture with the ink or paint used, for example, for bar codes, or else arranged around them ci, by tempography, serigraphy or any known or to be discovered means of printing.

Thus, it is the whole of the object to be stolen which will trigger, by passing for example to the detector gate or any other device provided for this purpose, the alarm signal caused by the magnetic field and its waves picked up by said device at gate or similar, as soon as the intensities and fields are compatible.

In extension to the process described by the present invention, a second detector, of metals for example (as in anti-terrorism checks at airports), will optionally be added, to signal the passage of a thief who has wrapped his petty theft in metallic paper. aluminum type, creating a "Faraday cage".

Let us give some examples, which it will have been understood that they are claimed by the present invention, that they are illustrative of the latter, but that they are in no way limiting, but extendable to all that is neighboring, that is to say to say object that one can
steal by suppressing the desired magnetization and deterrent.

1) Compact discs and all of their audio-visual neighbors: two methods are used, generally simultaneously: -painting -Ink (and its color) and its text, even its logos and designs.

Of course, the process of ink, varnish and / or magnetic paint is applied to the product to prevent theft, where it is appropriate.

 There is no point in affixing a pastille or the like on the packaging or even placed in it, because the thief will remove the disc from the latter and put it in his pocket before re-disposing said packaging "on the shelf" (or linear), thus hiding, apparently, the reality of the larceny. The same is true for all audio, visual and audio-visual reproduction methods and devices.

The present invention innovates by using on the audio, or visual or audio-visual support itself, there where the magnetization once demagnetized, does not interfere with the reproduction of sound and / or image (by transparency of the support) , the magnetic composition mixed with (or replacing) the ink, varnish or paint, or any other text or image support known or to be discovered, in order to place them there. If a field is used in the magnetic layer, for example H / S, or if short lengths of said magnetic layers are added with appropriate fields of different values (H1, H2, H3, Hn,
etc ...), we will produce information retrievable for reading by the appropriate reader (s).

Because the variations of remanent fields arranged in the magnetic layer (s) by magnetization, will appear in "reading", for example a mark, an identification number, a code, etc ... which will be erased by demagnetization, for example at the cash register, leaving the demagnetized product, henceforth not detectable by excitation, at the exit control gate.

Of course, it is possible to demagnetize in part, thus erasing certain information, while re-magnetizing another part (bands, fractions of bands, different fields) now at saturation, preferably.

We have seen that, for example, on a compact disc, it is possible to paint, ink or varnish flat (colors) or texts, or ink the external or internal edges, with a magnetizable ink, varnish or paint. and demagnetizable or, again, magnetizable and demagnetizable then partially re-magnetizable.

The slices are provided to make the operation possibly two-sided.

We have also seen that it is possible to complicate the process by adding to the composition of the ink, varnish or paint and other supports known or to be discovered, a support for magnetic fields.
H1, H2, H3, Hn, ... whose property is to make audio and / or visual playback impossible due to image and / or sound interference, as long as the appropriate demagnetization has not been carried out .

It will be added that the other methods and spaces of application of the magnetic layer (s), with their appropriate fields taking into account the recording medium and its variation and density (high, medium, low ... ) can be combined with the above, for example: a- surrounding the bar code by a frame of appropriate shape which will have the properties of being demagnetized when the object passes to reading (laser) said code with bars (or at the cash register), because the reader device will be completed by a demagnetizer device corresponding to the fields used, either to remain magnetized and, thus, to be demagnetized taking place elsewhere, instead of simultaneously.

b- impregnation of any part of the packaging (s). On this subject, the process described and claimed here, authorizes a permanent storage of a code, for example, not audible but detectable when we know it, by appropriate reading, allowing to know if what we are looking at and (or ) listening, is an unauthorized reproduction as stipulated, by law, on the original medium. Indeed, said original medium includes a visible trace of its original state, by the composition that is the subject of this text. If on reading, we find the code that was recorded there and which is only noticeable to those who know where and and how (and what) to listen and (or) see, we will have proof of pirate duplication. terms, the simultaneous detection of the residual code after demagnetization and the secret code recorded on the audio and / or visual medium, makes it possible to prove fraud, legally.

2) Bottles containing a valuable liquid product.

Four methods can be used, separately or
concomitantly: -on the bottom of the bottle.

-on the cap (center or edge).

-on or under the main or secondary label.

-on or under the capsule with fiscal legal seal.

By keeping an accounting record of sales, when, to whom, where, it will be possible to prove by discovering a bottle, a concealment, theft or possible complicity, by reading the memory located in the composition (even after demagnetization, for example during the purchase) arranged on the bottom, the seal, the label, in and on the edge of the stopper and it will be understood that these examples are illustrative and not limiting.

We will take care, during the demagnetization of certain elements, to re-magnetize what we want to leave or keep in memory, in the composition: code, numbers,
dates, provenance, brand 3) Miscellaneous clothing:
Four processes can be, mainly but not limited to, it will be understood, used - arrangement of the coating, ink, varnish, painting
-on, around (edge) and under the buttons.

 -on, in and under the zippers called "zipper".

-and preferably arranged on a support, preferably flexible:
- sewn in a hem, lining or any space
provided for this purpose, on a flexible magnetic support,
undetectable, preferably identical in form, to
the magnetic strip of a bank card.

-on, in or under the leather of a coat, jacket,
garment, boot, shoe, glove or any garment
(or by acting), known or to be discovered.

-Extension to all that is used for a sport or a playful game: under the leather of a ball, a racket handle, golf club, and it will be understood that the present invention claims the places of disposal of the process, especially when you can impregnate, print, paint or arrange a layer or coating such as
described here, with or without support, as shown above.

4) Vehicles of all toroids.

two methods are claimed in the context of the present invention -painting, varnish, inking, coatings arranged on, in or under
everything that is part of the vehicle and which does not pose any problem of a possible magnetic barrier of the "Faraday cage" type bumpers, hubcaps, glasses, plastics, leathers, fabrics, natural or synthetic rubbers ... all of which are detectable by an appropriate device, fixed or portable, by proximity during the control.

- same elements as above, but produced with a sufficiently strong magnetic layer with saturation at the magnetic level of the chosen field or fields, so that a detector device at medium distance, for example coupled to radars and other detectors of the police or the gendarmerie, can detect and signal the passage of the vehicle "equipped with its transmitter field", that is to say that it will not have been "cut" voluntarily by the user (authorized), before setting while the vehicle is running.

The glasses of the windows, various lights or headlights, bumpers and hubcaps or protective strip (for example lateral) in their thickness or below, we seem to be the best supports for the device, but not limited to, in
having H1 fields in the coating, ink, paint or varnish,
H2, H3, Hn ... different and, of course, by adapting to said vehicle a magnetizer device (in whole or in part, according to the will of the user), and demagnetizer at will (and close to the support (s) , we will have the opportunity to let identify, for example in the parking lot, certain detection elements (unstolen car, simply in the parking lot, system cut off and indicating it to detection), but not others (stolen car and indicating it The constabulary or the guards or any attendant equipped with an appropriate magnetic information reader, then being informed as appropriate.

5) Other uses for information only.

In 1) paragraph a-, the principle of surrounding the bar code, cited as a non-limiting example, has been explained, it will be understood.

Two classes and means of using the process of magnetization then demagnetization, total or partial, followed or not by a total or partial re-magnetization, are claimed within the framework of the present invention.

a- Any item sold and which, therefore, is presented to the public who can steal it, has a mark, a text, accompanied by a user manual, in short an impression made using a varnish, ink , painting or coating: the aforementioned will be carried out using a magnetisable composition such as described within the framework of the present invention, to be detected there, when and where it is appropriate, bar code included.

b- Any item sold in a package that can be removed in order to remove the detectable magnetic medium, falls into two categories: -which is eaten and drunk.

- what is not eaten or drunk.

The previous text describes the process, device, composition and methods of application and use claimed, for everything that is not eaten or drunk.

Let us add to the claims, subject possibly to appropriate medical or ministerial authorizations, that the composition of the magnetizable and demagnetizable support will make it possible, preferably after demagnetization, the ingestion of said composition.

Two scenarios then arise: bi - The product has not been consumed by the potential thief and, not demagnetized, it triggers the warning system during the fraudulent exit of said thief, if the stolen goods are stored on him ( without "Faraday cage").

b2- The product has been ingested by the potential thief and it is a product - known or to be discovered - authorized by the appropriate medical authorities. It is then an equally suitable detector, the sensitivity of which to weak magnetic fields is calculated accordingly, as well as "the proximity detection means", which will detect theft, when the potential thief passes.

Claims (9)

 CLAIMS:  1- Composition of varnish type, ink 7 paint, coating and application processes, characterized in that they are magnetizable in whole or in part and applicable by tempography, screen printing, magnetography and any other printing or impregnation process, anything that can be stolen. This allows, except for total or partial demagnetization, the magnetic detection of the object or device that may have been stolen. 2- magnetized zones formed of a possible set of magnetic domains according to claim 1, characterized in that said zones take the form, the arrangement, the location corresponding to those of the characters which are printed, impregnated or arranged, for example around a barcode, between two sheets of glass, on or under any surface or hidden in a hem, in a so-called "zipper", on, in or under a label, a bottle cap or bottom, on the surface or in a stopper, a capsule and anything used to close a product. 3- magnetized zones according to claims 1 and 2, characterized in that they are first coated with a magnetizable and demagnetizable composition regardless of the process used, known or to be discovered, then they are magnetized by any process suitable, known or to be discovered, in order to produce waves born from the induced magnetic field H / S, or from several fields of different values, H1, H2, H3, Hn ... During total or partial demagnetization, before possible re -partial magnetization, we will remove using a suitable device, the field (s) desired (s). When the thief comes into the field of the control-detector device, it will be excited by the non-demagnetized field and the alarm will sound. 4- magnetizable zones according to claims 1, 2 and 3, characterized in that they take the form including typographic of the printed, screen-printed, painted or coated elements, in short arranged on the support by its manufacturer, even if it is not there was no magnetization against theft: everything flat, image, logotype, text, form and function or only part of the said, will be made magnetizable then demagnetizable in whole or in part, due to the use to do this, of the composition claimed, magnetizable, demagnetizable, used as it is or mixed with a coating, varnish, ink, paint or any other graphic or packaging or even handling medium. 5- Appropriate distribution of the magnetizable zones according to any one of the preceding claims, characterized in that certain magnetic fields and their supports, do not interfere with audio and (or) visual reproduction, even on a transparent support: therefore, the distribution can be done anywhere, including on the internal or external slices, in order to make the process efficient front and back, but also characterized, in the case where the process, magnetized, interferes with the audio and / or visual reproduction , by the fact that efficiency will be added, by distributing said magnetizable zones on the location of the readings, for example "laser" (optical reading), even though said locations, demagnetized zones, will not interfere with said  reading. 6- A method of printing or impregnating the magnetic layers according to claim 1, characterized in that it suffices to paint or impregnate the composition on the support, in a place absent from "Faraday cage" (or similar ), but also characterized by the fact that a magnetographic printer with one or more heads will also be used, where appropriate. 7- Additional regulator device according to claim 1, characterized in that, on a vehicle, this example being non-limiting, it will be necessary to magnetize then demagnetize, in whole or in part, so as not to be detected when it is not necessary . It is a magnetizing device, adjacent to each zone to be magnetized, activated by electricity with a breaker, usable repeatedly and at will. A magnetographic printer with several heads, will create the fields H1, H2, H3, Hn ... desired, or else, we will use a device to paint, to coat, to ink or to varnish. 8- Mixture of the magnetic composition with a support approved by the competent authorities, characterized in that it can be ingested, that is to say eaten or drunk, without damage to the body and that its presence, as is done by radiography but, here, by magnetographic reading. 9- Permanent storage of a code in the composition, according to claim 1, characterized in that it allows to identify even after demagnetization, the information contained in the magnetic composition: which has the effect, giving in illustrative example an audio "compact disc", to be able to insert in and during the recording of the sound, a signal apparently inaudible but detectable when one knows how to look for it. It will suffice to compare said signal with the information contained in the magnetic composition, to define for sure and legally exploitable as evidence, the possibly fraudulent duplication of the work (protected); 10- Various locations of the magnetic zones according to any one of the preceding claims, characterized in that, hidden under a visible and useful part of the object to be protected, they will be out of the sight of the thief: for example, under leather racket or club or ball, on the edge or under a button, under or in leather or plastic or the fabric of the strap of a watch, the lining of a garment, impregnated or placed in or on a suitcase, packaging, in short, everywhere where nothing is visible, but where the detection penetrates and reads. Mention will also be made of glasses, plastics or various rubbers, located on vehicles, or even painting of the bodywork or bumpers (preferably in non-metallic materials) and other hubcaps.
