Abstract

A laminated product having a thickness that can be adjusted by chipping, and including alternating sheets and layers of an adhesive material in a stack, each sheet possessing an intrinsic resistance to tearing and each layer of adhesive material connecting adjacent sheets in the stack with a linking force which is weaker than the resistance of the sheets to tearing, enabling each sheet to be detached from the stack without tearing. The product includes a housing which is disposed inside the thickness of the stack, and an electronic identification element which is disposed in the housing.

Claims

1. A laminated product having a thickness adjusted by exfoliation and including:

a stack of alternating sheets and layers of an adhesive material, each sheet having resistance to tearing, and each layer of adhesive material connecting two adjacent sheets of the stack to one another by a bonding force which is less than the resistance of the sheets to tearing, so that each sheet can be detached from the stack without being torn;

a housing within the thickness of the stack; and

an electronic identification component located in the housing.

2. The product according to claim 1, wherein the electronic identification component includes a memory for storage of identification information identifying the product, and transmission device that can be queried at a distance for transmitting the identification information stored in the memory.

3. The product according to claim 2, wherein the identification information stored in the memory includes at least the serial number of the product.

4. The product according to claim 2 wherein the memory has a storage capacity sufficient for storing at least a part of identification information including:

identification of manufacturer of the product, type of product, reference of an order for the product, identification of client, identification of material constituting the product and reference of a material certificate, reference of a standard applicable to manufacturing of the product, reference of technical specifications of the product, reference of certificate of compliance with the standard, manufacturing date, reference of a delivery voucher, and delivery date.

5. The product according to claim 4, wherein the memory has a storage capacity of at least 512 bits.

6. The product according to claim 4, wherein some of the identification information is stored in the memory in coded form.

7. The product according to claim 4, wherein the transmission device receives the identification information at a distance and writes the identification information in the memory.

8. The product according to claim 7, wherein the electronic component can be locked in terms of writing.

9. The product according to claim 4, wherein the electronic component has a cylindrical shape with an exterior diameter of less than 4 mm.

10. The product according to claim 4, wherein the electronic component includes means for measurement of temperature and/or of pressure and/or of vibrations and/or of irradiation, and the transmission device transmits measurements made.

11. The product according to claim 2, wherein the memory has sufficient storage capacity for storing basic identification information, other identification information being stored on an external support.

12. The product according to claim 11, wherein the electronic identification component has a thickness less than 200 μ

m.

13. The product according to claim 11, wherein the electronic identification component has a cross section less than 2.5 mm².

14. The product according to claim 11, wherein the memory has a capacity greater than 64 bits.

15. The product according to claim 11, wherein the electronic component has a read-only mode.

16. The product according to claim 1, wherein the housing is delimited by an interior wall, and including a hardening filling material filling the housing around the electronic component and bonding the electronic component to the interior wall.

17. The product according to claim 15, wherein the filling material is selected from the group consisting of, an epoxy resin, a phenolic resin, vinyl ester resin, and a polyvinyl resin.

18. The product according to claim 1, wherein the sheets consist of a metallic or composite material.

19. The product according to claim 1, wherein the sheets extend parallel to a plane of reference, and the housing also extends parallel to the plane of reference.

20. A system for identification and monitoring of laminated products having thicknesses that can be adjusted by exfoliation,

each of the products including a stock of alternating sheets and layers of an adhesive material, each sheet having a resistance to tearing, and each layer of adhesive material connecting two adjacent sheets of the stack to one another by a bonding force which is less than the resistance of the sheets to tearing, so that each sheet can be detached from the stack without being torn, and

each of the laminated products including an electronic identification component, and a reading unit, the electronic component containing a memory for storage of identification information identifying or characterizing the respective product, and a transmission device for transmitting the identification information stored in the memory, a reading unit communicating with the transmission device of the electronic component and consulting the identification information stored in the memory.

21. The system according to claim 20, wherein the reading unit is portable and communicates at a distance, without a wire link, with the electronic component.

22. The system according to claim 20, including an information processing unit for management of the identification information, and a reading unit for transmitting the information read from the memory to the information processing unit.

23. The system according to claim 22, wherein the reading unit transmits to the electronic component the identification information managed by the information processing unit, for writing in the memory.

24. The system according to claim 22, wherein the information processing unit carries out coding and decoding of certain identification information stored in coded form in the memory.

25. The system according to claim 24, wherein the coding and decoding of the identification information are done using tables putting in correspondence the information to be coded and an alphanumeric code to be stored in the memory.
