These systems are generally of the wired type, a detector attached to the object being connected by wire connection to a central monitoring.

The invention also relates to an operating method for presentation on the means of presentation of information of a given location of information relating to the object disposed in this location while the objects carrying their own detectors can be placed and moved in any of the locations by functional operations performed by and in the device of the invention.

The present invention, without being limited thereby, will now be exemplified with the following description of embodiments and implementation in relation to:

Figure 1 which shows a display with objects and presentation means in a first relationship,

Figure 2 which shows a display with objects and presentation means in a second relation after the objects have been moved, Figure 3 which is a structural-functional diagram of a particular example of implementation, and

Figure 4 which shows an example of implementation of the invention.

In the context of the invention, the term "central" which is currently used must be understood in a broad manner: it can be both a single housing receiving all the wired links of the detectors a set of housings connected together according to a determined topology of connection to the detectors, for example in tree structure. The term "host computer system" that is currently used must be broadly understood: it may be a single computer / microcomputer as well as a more complex computer system on a local network or across a larger network. In addition, the central unit and the host computer system, if they are preferably distinct entities communicating with each other, in variants they can be grouped together, for example in the case of a microcomputer comprising an expansion card with inputs / outputs connected to wired links and detectors.

In addition, the term detector must be taken in a broad sense since the detectors are used for some detection of theft of objects and others for the detection of consumer interest in objects. These two functions can be physically separated, in separate detectors or grouped together in the same detector element. In addition, as will be seen the detection of the consumer interest can be obtained by any type of detection: movement, contact, capacitive, optical, etc. Preferably, a single physical detector with both functions, flight detection and detection of consumer interest, is connected to each object. In the latter case, the detector or object identifier can be obtained both during the detection of a theft and the consumer's interest for said object, which can simplify the management of associations between objects and means for displaying information.

The same detector is thus capable of transmitting to the central unit a different signal respectively corresponding to:

- a separation of the object from its detector, a classic case of theft,

- disconnection of the wired connection (disconnection on the side of the detector or disconnection on the side of the control panel input), which may correspond to theft or maintenance,

- manipulation of the object or other type of detection of the interest of a consumer on an object.

In the first two cases, the system is configured to trigger an audible and / or visual alarm from the control panel and / or from any other suitable equipment connected to the system. It is understood that it is possible to inhibit the alarm in a maintenance mode of the system in which it is desired to set up, rearrange or remove the items on the display stand. The third case, is the implementation of the dissemination of information about the object on the means of presentation in relation to the object on which the consumer has expressed interest. In the third case, it is also possible to record the data relating to the interest of the consumers, for example the number of manipulations and / or the duration of the manipulations, to analyze the impact of the objects and / or other actions. (advertising ...) in relation to objects, on consumers.

In a general manner, the device of the invention allows a presentation of information on the means of presentation which corresponds to the object under consideration thanks to the associations that it manages between the references of plant inputs and detector identifiers and and / or object identifiers, and information or sources of information and, optionally, according to the implementation methods, the object references and / or the correspondences between the presentation means and the plant entry references in case there is a possibility of moving the wire links and / or presentation means with respect to the different locations of objects of the display. It is therefore understandable that there are various possibilities to manage these associations and in particular the levels of association and the steps to achieve this result. In a particularly simple mode, a reference association of plant with information or information source is available and it is sufficient that the device knows the plant entry reference for the object for which it must disseminate information for obtain the expected result, the restitution means corresponding to the central input reference. In more complex terms, the information or sources of information are associated with object references and it is therefore necessary to have at least one additional step to determine the object reference from the detector reference by use. of an association stored in the device. Other methods are still possible, especially if the device is associated with other functions such as inventory management or billing for which tables containing data related to that used by the device are available.

It should be understood that, according to a variant of the invention, all the data recorded in the control panel and / or the management means, in particular the association tables, can be controlled and modified remotely using a means management information (server for example) to which they are connected. This variant makes it possible to remotely coordinate changes within an object presentation space with the presentation of corresponding information and with the corresponding antitheft alarm management. The changes can be made manually or be the result of an automated process following the detection of object placement, object removal, object movement, data identification (identifiers / references) available (object, plant entry ...) allowing it.

In particular, several different devices according to the invention can be connected to the same management means and thus the reorganization of a space for presentation of objects and information relating to these objects, as well as the protection of objects against theft, can be managed centrally, possibly away from the very place where this presentation is made.

The display shown in Figures 1 and 2 comprises a set of locations 1a, 1b, 1c ... 1 i in which objects P1 to P8 are arranged. Each of these objects has a detector attached to it and each object-detector pair forms a specific duo. The detectors are connected by wire links to independent entries referenced by a central. The detector can be connected or disconnected from the wired link. The detector is coded and has a unique detector identifier for each detector, a detector identifier that can be read by the panel. Thus, each object can be individually identified by means of the identifier of the detector that it is glued.

In addition or alternatively, the object can be identified by a unique object identifier which is stored in the object and which can be read in radiofrequency, for example according to the NFC standard, by the detector. For this purpose, the detector comprises radio frequency reading means according to the NFC standard of data contained in the object and, in this case, the central unit can recover, via the detector and the corresponding wire link, data contained in the object including at least the object identifier but it should be noted that other data can be stored in the object and be read in some implementation variants. The control unit communicates with a microprocessor or microcomputer-type management means which is in the example a host computer system. Optionally, the central and / or the management means communicate with a server (not shown) placed remotely.

The display unit also comprises presentation means 2a, 2b, 2c ... 2i of information, here to type of display screen (Display 1, Display 2 ...) on which information (Medial, Media2 ... ) can be presented. In general, the presentation means can be of any type: audio, video, more generally multimedia. Each object location of the display unit has its own presentation means which is in close relation with it. Thus, each means of presenting information is associated with an object location. It can also be provided that a single means of presenting information is associated with several locations of objects placed in a neighborhood relationship with it.

The invention allows an automatic presentation on the means of presentation of a given object location, the presentation of information about the object that is at this location while the objects with their own detectors can be arranged or moved freely between the various locations of the display. In a simple implementation, at each object location corresponds a presentation means and each presentation means is referenced / identified by the central input reference corresponding to the wired link arriving at the object location in relation. with said presentation means: the wired links are not movable between the inputs of the central unit and the presentation means are not movable in the display.

At each positioning location 1a, 1b ... of an object in the display unit corresponds to a reference input of central unit a, b ... determined the central. In the implementation mode now described, the plant entry reference for a given location of the display is immutable, which simplifies said implementation. Thus, the location 1a corresponds to the central input reference a, 1b to b, 1c to c ... and the location 1i to the central input reference i. Likewise, the presentation means 2a corresponds symbolically to the input reference of the central unit a, 2b to b ... and the presentation means 2i to the input reference of the central unit i. On the other hand, the objects P1, P2 ... with their own detectors can be changed or moved from one location to another of the display stand by disconnecting and reconnecting the detector of the duo of the / to the wired link of the location. Remember that the detector remains stuck to the object and forms a duet with the latter. The means of knowing the object which is at a given location, therefore a given input of the central station, therefore passes by reading the detector identifier or the object identifier as the case may be. We have seen that here, the presentation means is fixed and is referenced by the central input reference of the location with which it is in a neighborhood relationship.

Having for each object information (text or image for example) or a source of information (name and / or address of a file for example) to retrieve the information, specific to the object, for dissemination on the means of presentation of information, thanks to the relation between the detector identifier or the object identifier and the central input reference, it is possible to determine on which means of presentation of information it is necessary to send the information concerning the object considered. For this a number of associations are made between the identifiers, references and information. It is understood that it is possible to obtain this correct information presentation using various kinds / levels of associations.

Associations can be created and managed in a volatile manner when information is needed. In an alternative, the device stores in memory of computer means, in a database, associations in the form of tables.

For example, the device can use the following technique. When an object is manipulated, the detector sends a signal that it transmits to the control unit via of the wired link. The control unit detects it, and creates an association: central input reference with the detector identifier or the object identifier as appropriate for the object being manipulated. For example, the detector stuck on the object may include a motion detector. From there, if the device already has an association table object information (or information source) with detector identification or object identification, the device can send the corresponding information on the means of presentation having the same plant input reference as that of the object being manipulated. Alternatively, if the device already has an object information association table (or information source) with object identification, regardless of whether or not the detector could have read in the object the identification of the object. object, the device can add an association level with an association table: detector identification with object identification. In the latter case, an additional step is therefore necessary to obtain the object identification from the table and the detector identifier read, the object identifier contained in the object could not be read directly by the detector, which ultimately provides the information for the object in question. Note that, alternatively, an object reference can be used. In general, however, the object reference and the object identifier, although from different sources, may be of the same type and value, for example a numerical or alpha numerical value resulting from a standardization concerning the identification of objects.

With this technique, if the objects are moved as shown in Figure 2 with respect to Figure 1, the information returned are always those relating to the object manipulated by the consumer on the means for presenting the location of said object. For example, the object P6 is passed to the location 1b always corresponding to the same wired reference link of the control panel b since the wired links and their inputs on the control panel are not modified. Thus, the device has all the elements to determine that if the object at the location 1b which has the central input reference b is manipulated, it must be restored on the presentation means corresponding to the input reference. central station B information related to an object P6, object whose identity or reference is obtained indirectly or directly by reading the detector identifier or the object identifier of said object.

Figure 3 is a particular example in which the associations are in the form of tables stored in the device, preferably in the host computer system. The associations considered here are relatively numerous since we have:

an object reference association table (object ref) with information or sources of information (INFO MEDIA),

an association table input reference of central (input) with reference of means of presentation (multimedia restitution) - this table which can be omitted if there is fixed correspondence between the central input reference for an object location and its presentation means - a detector identification association table (Id detect) with object reference (Object Ref).

It is understood that in the case where there are communicating detector-object duos, making it possible to generate in the device object identification data, other complementary or alternative association tables of the preceding and comprising the identification of object can be implemented, which can simplify the process of restitution of the information. This possibility of reading the object identifier is represented for the object P1 by symbolization of radiofrequency exchanges for reading and transmission of data contained in the object, including the object identifier (which is here Reft to allow the use of the same tables) and, optionally, information or sources of information (INFOt). The control unit allows the diffusion of these data, as well as, in a general way, the detector identifier and the control unit input reference throughout the device.

The control unit comprises reference inputs a, b ... i connected by wire links to the detectors having respective detector identifications Ida for the object P1, Idb for the object P2, Idj for the object Pi. the object references Reft to the object P1, Refo to the object P2 and Refc to the object Pi. The information presentation means are referenced here / addressed A1 for that of the object location corresponding to the reference for the input of the central input a, A2 for that of the object location corresponding to the input of the control unit b and Ai for that of the object location corresponding to the input reference of the control unit i.

The tables shown in Figure 3 and stored in the device reflect the associations as shown in this Figure. These tables are preferably updated automatically according to the connections and disconnections to the central detectors duets. Note that information or sources of information, for example a file address or page on a computer network, may possibly come from objects in the case of communicating duos. However, most of the time they come from external data sent by the manufacturers of the objects.

At the bottom of Figure 3 is a simplified flowchart implementation of the device shown. As a result of the manipulation of the object Pi, the control unit is informed by the detector of the duo concerned, the detector having for example a motion detector. Following this information, the device determines that it is necessary to carry out a restitution of information concerning the object of the duo concerned of the input input of central input i. For this, the identifier of the detector is read for the input input of central input i, which gives Idj. Then from the appropriate association table: detector identifier (Id detect) with object reference (Ref object), the object reference is determined, that corresponding to Idj being Refc. With the Refc object reference and using the appropriate association table: object reference (object ref) with information or information sources (INFO MEDIA), information or sources of information corresponding to Refc are determined and here are "blah ... blah".

Finally, the address / reference of the information presentation means to be used is determined by using the appropriate association table: central input reference (input) i with presentation means reference (multimedia reproduction) Ai.

We understand that the table structure that is given in this example of the

Figure 3 is indicative. In implementation variants, the tables may be structured in different ways, for example by grouping together within a single data table from several tables of the exemplary embodiment. In addition, other data may be associated with those of the tables of the exemplary embodiment, in the same tables or by creating other tables. Thus, in addition to the reference of the object which may be a simple numerical or alphanumeric reference, it may include the clear name of the object, its manufacturer, its price, and / or any other data related to said object. Regarding the information to be restored, directly or not, there may be several types depending on the capabilities of the playback equipment, we can use an interactive reproduction if the playback equipment allows ... For the table associating the reproduction equipment with the plant input references, it is possible to add data on the capacity of reproduction of said equipment, which can be useful for a choice of information to be rendered. In variants, another table associating the plant input references with the identifiers of their detectors can be stored and is updated regularly by reading the detector identifiers for each input of the plant. This table can be used at the first time means for restitution of the information on the reproduction equipment in relation to the object instead of the direct reading of the detector identifier in order to obtain the latter. In addition, the device can manage other associations such as those relating to the measurement of consumer interest for objects in a manipulation time association table with object reference or object identifier, for example.

In a particular embodiment, a control panel comprising several wired inputs is connected to a computer equipment by a wired computer link, typically USB but may be of the local or remote network type. On each input of the central unit, is connected by a wired connection, a detector housing comprising both a function of detection of theft and detection of consumer interest for the object protected by the detector housing. The separation of the housing detector with the object causes the detection of a flight in case this detection is not inhibited. The manipulation of the object with its detector housing leads to the detection of the interest of the consumer for this object. This last detection can for example be obtained by motion detection of the detector housing or switching of a direct contact (probe finger) or indirect contact (ILS) during the separation of the support case from the display stand on which the object was placed. . The wired connection between an input of the central unit and a detector housing is fixed and arrives at the object side in a determined location which includes in its vicinity means for retrieving information corresponding to this location. It should be noted that the same information retrieval means may be common at several locations and therefore inputs from the central.

In the case where the object identifier is provided by the object itself by radiofrequency transmission, the correspondence between an input of the central unit and a given object is direct, the restitution of information concerning this object will be done on the means of presenting information corresponding to the input of the corresponding central unit. In the case where the detector identifier is transmitted to the central station, the correspondence between an input of the central unit and a given object is indirect, a correspondence table between detector identifier and object being used. However, it is understood that the structure of the correspondences can be managed differently between various implementations or even within the same implementation: the tables used with or without particular matches such as that of detector identifier and identifier object and possibly object reference. Indeed, the table giving the reference information to be broadcast (or even giving information directly) that can have as target data is the central input reference, or the detector identifier, or the object identifier / reference , these data can even be associated in the case of a non-purely relational database. In the latter case we can even provide a single table (for example a spreadsheet) with all potentially useful data (object identifier, detector identifier, possible object reference, plant entry reference, reference of information to be broadcast ...), individual data being possibly absent in certain cases (for example no object identifier if it does not include a radiofrequency identifier or the detector does not include a radio frequency reader).

In Figure 4, a display 3 comprises for example a first object 5 (mobile phone) and a second object 6 (camera). A first detector 4 is in relation with the display 3 and the first object 5. This first detector comprises two detection contacts: a first contact 4 'in relation to the object and whose function is to detect the theft in case of separation of the object with the detector, and a second contact 4 "in relation with the display and whose function is to detect the consumer's interest in separating the detector from the display stand. The second object 6 is monitored by a detector always dual function of detection of theft and consumer interest but this time the contacts or other detection means 7 (theft) and 8 (consumer interest) are deported by wire from a detection box 9. The detectors 4 and 9 are connected to the monitoring station 10 by wire links 14 arriving at specific identified inputs of the central unit 10. At each input of the central unit there is a means for rendering information 12, 13 in neighborhood relation with the end of the wire connection corresponding to the input and on which end will be connected a detector for a given object. The central unit 10 is connected by USB connection 15 to a microcomputer management means 11. The management means January 1 is connected to an alarm generating means 16 for example sound but as an alternative or complement, the central unit 10 is connected to this / another alarm generation means. The control unit transmits by means of data management a function of events occurring in relation to the detectors (theft, consumer interest, for a given central input and / or detector identifier given and / or given object identifier if readable at distance by the detector). In return, the management means can control the operation of the control unit, for example disable certain inputs or types of detection (for example, for a given control panel input, deactivate the detection of interest by keeping the flight detection or deactivate the detection. flight detection). It is understood that if the control unit can directly control the alarm generating means, the deactivation of certain functions of the control unit (in particular alarm) is necessary. On the other hand, if the management of the alarms is done entirely in the management means 11, the deactivations of the central unit are no longer necessary. The management means January 1 is configured to track the positioning of the products and to allow the return of information about each product to the correct location among the information retrieval means 12 and 13 and in the manner views.

Naturally, the present invention is not limited to the particular embodiments which have just been described, but extends to all variants and equivalents in accordance with its spirit. It is thus clear that the invention can be declined according to many other possibilities without departing from the scope defined by the description and the claims. Thus, while for the exemplary embodiments the use of the NFC standard has been indicated for radiofrequency transmission, it is clearly understood that the invention can also operate with other standards or modalities for radio frequency exchanges. In addition, thanks to the management means implemented, a given information presentation means can be associated with one or more given locations of objects, the tracking of the objects with respect to their locations and means of presentation of the information. neighborhood / partner information is performed correctly.
