Abstract: High security seal that can be reused an indefinite number of times because the authenticating part evolves in a chaotic manner each time the seal is opened and then put back into service. This seal is composed of at least two authenticators (1) and (2) at least one of which is movable with respect to the other into the open position. These two authenticators become fixed and stable in the closed position. In each new fixed position, the two authenticators cooperate to generate a new authenticating feature that is stored in a database in order to be compared during a check. This feature will be cancelled and replaced with another one when said seal is fraudulently or deliberately opened and thus will provide proof that it has been opened.

Abstract: The invention relates to a method and device for verification of non-violation of the integrity of a system or the identity of an object. An authentication seal is used, comprising a physical authenticator with bubbles (3) produced by a chaotic process on the production thereof, a characteristic of which is to be always unique and non-reproducible. A representation of said identifier with bubbles is stored in the form of an image and/or digitally in a database local or remote to the address (17), for authentication of the assignment of the identifier in situ or on the object for protection. Said authenticator is provided with a physical connection (16) which permits connection to the site or object for identification. Any attack on the integrity of the seal, whether on the authenticator and/or the connection, irreversibly alters the total seal such as to render the same un-reusable.

Abstract: This invention involves a reading process for three-dimensional means of identification (100) that are unique and non-reproducible (100), containing a mixture of at least two materials (110 and 120) that are distinguishable from one another (110 and 120), remarkable in that it consists of one part to recognize the internal heterogeneous structure of the means of identification (100) in two dimensions, and another part to verify and prove its third dimension to render falsification impossible. This characteristic reduces the amount of storage memory as well as the length of time necessary to perform the operations of reading, acquisition, and comparison usually conducted in such processes. The invention also involves a device that implements said process as well as a means of identification adapted to said process.

Abstract: A method for making transactions secure based upon a card-type medium (2) comprising a number (4) and a remote database (5) connected to a telecommunications network. A unique and non-reproducible identifier (3) in the form of a bubble code is physically affixed to the card (2) comprising a number (4) contained either on a magnetic strip, of a bar code, or in an electronic label.

Abstract: A method and apparatus for carrying out the deposition of a paste like and/or viscous material, such as solder paste, on a substrate through the apertures or openings of a stencil are provided for use, for example, in screen printing in the mounting of components on a printed circuit board. A hollow receptacle for the material is provided with a lower aperture which is orientated towards the stencil. The lower aperture of the receptacle is delimited defined such that its length is adjusted to the dimensions of the substrate and that its width is a function of the speed of execution of the screen printing. This delimitation is implemented by sealing members preferably comprising two wipers on respective sides of the aperture, transverse with respect to the direction of displacement of the receptacle, orientated one towards the other and inclined with respect to the horizontal between the wipers at an angle of between 120° and 180°.

Abstract: A stencil (8) with a tension part combined with an operational device allowing deposition of solder paste to replace constituents on an electronic board. The stencil consists of a flat sheet (1), of rectangular shape, made of synthetic flexible material or metal and outfitted with transfer openings (2) for transferring and distributing a product. Two of the parallel sides of the sheet are connected to rigid and mobile vertical tabs (3) in an affixed position on a tension unit of the sheet. The other two parallel sides of the sheet, orthogonal to the former ones, are extended with flexible walls (6), orthogonal to the sheet. Bead folds (7) separate the perforated sheet and each of the flaps and delimit the sheet. The flaps freely rotate around the folds. The invention also has an operational device consisting of arm (20) with several jointed strands outfitted with a sole means of locking (22) its joints. The stencil may be configured and moved in accordance with 6 degrees of freedom.

Abstract: The present invention concerns a stencil for the depositing and gauging of more or less thick, point-base coats of a viscous product. To remedy the problems found with a serigraphic screen made of polyester or metal cloth and a metal stencil, the present invention proposes use of a solid sheet of uniform composition made of synthetic material and, preferably, polyester without the inclusion of wires. This polyester solid sheet is bored mechanically or thermally at the places desired. Since the polyester cloth is solid, it admits of tension forces greater than those of wire mesh cloths or at least equal to those of metal stencils.
