Patent Description:
The RF chip(s) include(s) one or several Near Field Communication (or NFC) type chips, as a Secure Element(s) (or SE), that are incorporated in a security document, such as an electronic passport or termed e-passport.

Within the present description, an SE is a smart object that, on one hand, protects access to data that the smart object stores or processes and, on another hand, is intended to communicate with a reader, like e.g., a gate, a Personal Computer (or PC), a tablet or a mobile (tele)phone.

Furthermore, the invention pertains to a method for making an assembly for shielding at least one RF chip.

<CIT> describes a shield that allows shielding an RF chip. The shield includes a flexible non-metallic substrate that has a metallic coating. The shield may be incorporated in or adhesively adhered to an article with an RF chip.

Further shields for shielding an RF chip are described in <CIT> which represents the basis for the preamble of claim <NUM> and in <CIT>.

However, such a shield is not efficient enough in terms of blocking an RF signal(s) that is(are) sent to the RF chip or that originate(s) from the RF chip.

There is a need for a solution that allows improving a provided RF shielding efficiency.

The invention proposes a solution for satisfying the just herein above specified need by providing an assembly including a shield.

According to the invention, an assembly includes a shield as defined in claim <NUM>.

The principle of the invention consists in a shield with two shield parts, namely a first shield part and a second shield part. The first shield part can be folded on the second shield part. Each of the first and second shield parts incorporate(s) or is(are) attached (or connected) to one or several closure elements. To obtain an electrical continuity between the shield parts and thus create a Faraday shield, the first and second shield parts are folded onto each other so that each of the closure element(s) associated with one shield part get(s) in (electrical) contact with a corresponding closure element(s) that is(are) associated with another shield part.

Once the closure elements are in a closed position, the shield is electrically closed through the first shield part, the second shield part and the closure elements.

The invention assembly allows securing RF access from and/or to an RF chip(s) included between the first and second shield parts (once brought together). The RF chip(s) is(are) included in a product or an article that includes or is bound to the assembly.

Once the shield parts are brought together, one or several RF chips that are sandwiched between the closed shield parts are thus electromagnetically isolated from the outside.

The invention assembly allows, thanks to an electrical closure between the shield parts, preventing from any passage of any RF signal between the inside and the outside of a resulting (electrically) closed assembly.

The invention assembly is technically simple and efficient against a passage of any RF signal between the inside and the outside of the resulting closed assembly.

Contrary to the aforementioned prior art solution, the invention assembly allows blocking an RF signal(s) that is(are) sent to and/or that originate(s) from an RF chip(s) that is(are) located within a space walled or surrounded at least in part by the shield parts (once brought together).

The invention assembly allows thus improving a provided RF shielding efficiency.

According to a further aspect of the invention, the invention is a method for making an assembly as defined by claim <NUM>.

Additional features and advantages of the invention will be apparent from a detailed description of a plurality of invention embodiments, given as indicative and non-limitative examples, in conjunction with the following drawings:.

Herein under is considered a case in which the invention assembly is used for shielding a single RF chip that is included in a product or an article.

However, the invention assembly is also valid for shielding a plurality of RF chips that are included in a product or an article.

The invention assembly may be used in any type of product or article, such as a security document, like e.g., an e-passport, an electronic driving license or an electronic identity card.

Naturally, the herein below described embodiments are only for exemplifying purposes and are not considered to reduce the scope of the invention.

The same references that are present in different figures refer to the same features.

The chip memory(ies) store(s) one or several Contact-Less (or CL) applications, as executable data to be executed by a chip CPU and/or (micro)processor(s), so as to provide a corresponding CL service(s).

Within the present description, the used adjective "CL" within notably the expression "CL applications" means notably that the application(s) is(are) accessible via a Short Range (or SR) RF link(s) by using, for example, International Standardization Organization/ International Electro-technical Commission (or ISO/IEC) <NUM><NUM> specifications, a Ultra High Frequency RF IDentification (or UHF RFID) technology or the like.

In a transponder mode, i.e. when the chip <NUM> is powered at least in part by an external CL reader, the chip <NUM> receives power from the CL reader and provides power to its internal components, so as to operate.

Alternately or additionally, the chip <NUM> is powered by a battery (not represented) that is connected to the chip <NUM>. The battery is included in or attached to e.g., the first cover part <NUM> or the second cover part <NUM>.

The wires or stripes <NUM> and <NUM> are electrically conductive.

The wires or stripes <NUM> and <NUM> may be positioned at the fold line <NUM> possibly at the opposite edges of the first shield part <NUM> and the second shield part <NUM>.

The first shield part <NUM> is preferably foldable onto the second shield part <NUM>.

The first shield part <NUM> and the second shield part <NUM> are presented, in the <FIG>, on one and the same plane (and are therefore not folded onto each other).

Each of the first shield part <NUM> and the second shield part <NUM> is preferably provided with one or several (electrical) closure elements <NUM> and <NUM>.

Additionally and/or instead of being incorporated in the first shield part <NUM> and/or the second shield part <NUM>, the closure elements are at least in part separate from the first shield part <NUM> and/or the second shield part <NUM> while being electrically connected to the first shield part <NUM> and the second shield part <NUM> respectively in a closed position. For example, a first closure element is included in the second cover part <NUM> (possibly in a strip that extends from the second cover part <NUM>) while being electrically connected, possibly through an electrical wire or stripe, to the second shield part <NUM> and/or a second closure element is included in the first cover part <NUM> while being electrically connected, possibly through an electrical wire or stripe, to the first shield part <NUM>. The first closure element and the second closure element cooperate with each other in an electrically closed position, so as to close a circuit including the first and second shield parts.

One example of corresponding female and male mechanical elements are a snap button, as known per se. The mechanical elements are electrically conductive. The mechanical elements constitute closure elements and are intended to cooperate or interact mechanically with each other, so as to close and maintain a corresponding Faraday shield in a closed position.

The magnetized element <NUM> and the metallic element <NUM> do not cooperate magnetically on <FIG> in a position that is opened.

The magnetized element <NUM> and the metallic element <NUM> are intended to cooperate magnetically with each other, so as to close and maintain a corresponding Faraday shield in such a closed position.

The shield, more exactly the first shield part <NUM> and/or the second shield part <NUM>, includes preferably one or several apertures <NUM>, <NUM>, <NUM>, <NUM>, <NUM> and <NUM>.

Each aperture <NUM>, <NUM>, <NUM>, <NUM>, <NUM> or <NUM> is deprived of any material and constitutes a through hole.

Each aperture <NUM>, <NUM>, <NUM>, <NUM>, <NUM> or <NUM> allows reducing the quantity of the material(s) that is(are) used to constitute the shield. Each aperture <NUM>, <NUM>, <NUM>, <NUM>, <NUM> or <NUM> allow(s) reducing the cost for the corresponding shield without impacting the shielding efficiency of the assembly <NUM>.

The aperture(s) may include one or several apertures <NUM>, <NUM>, <NUM>, <NUM> and <NUM> that face(s) at least in part a folding area, namely the folding area represented between dashed lines <NUM> and <NUM> around the fold line <NUM>, between the first shield part <NUM> and the second shield part <NUM>.

It is to be noted that the count and the shape of the aperture(s) that is(are) present at the folding area have no significant impact on the shielding efficiency of the assembly <NUM>.

The assembly <NUM> for shielding the RF chip <NUM> is presented in a position that is electrically opened.

<FIG> shows schematically the assembly <NUM> for shielding the RF chip <NUM> and the article cover <NUM>.

The assembly <NUM> for shielding the RF chip <NUM> is presented in a position that is electrically closed.

The user has closed the article folding the second shield part <NUM> onto the first shield part <NUM> while possibly handling the strip <NUM> and bringing together the magnetized element <NUM> and the metallic element <NUM>, as first and second closure elements.

The strip <NUM> that extends from the second shield part <NUM> is folded or bent to the cover <NUM> front side, as the other side of the first cover part <NUM>.

The first shield part <NUM> is folded, preferably along the fold line <NUM>, onto the second shield part <NUM>. The first shield part <NUM> is thus not electrically in contact with the second shield part <NUM>.

The antenna <NUM> and the chip <NUM> are sandwiched between the first shield part <NUM> and the second shield part <NUM>.

The first and second closure elements <NUM> and <NUM> are electrically conductive.

The metallic element <NUM> (hidden on <FIG>) faces the magnetized element <NUM> when the user has brought together the first shield part <NUM> and the second shield part <NUM> (and therefore the first cover part <NUM> and the second cover part <NUM>).

When the magnetized element <NUM> and the metallic element <NUM> are sufficiently close to each other, the magnetized element <NUM> exerts a magnetic and attractive force onto the metallic element <NUM>.

The magnetized element <NUM> and the metallic element <NUM> cooperate with each other in a magnetic fashion.

The magnetized element <NUM> and the metallic element <NUM>, as a magnetically attractable element, are closed in an electric fashion, i.e. are in an electrical contact.

The electrical contact between the first <NUM> and second <NUM> closure elements allows ensuring an electrical continuity between the first shield part <NUM> and the second shield part <NUM> and generating a Faraday cage or shield. The Faraday shield allows thus blocking any RF signal that is(are) sent to the chip <NUM> and blocking any RF signal that originate(s) from the chip <NUM>.

The magnetized element <NUM> and the metallic element <NUM>, as closure elements, close electrically the thus formed Faraday shield. The Faraday shield allows blocking incoming and outgoing electromagnetic fields.

A conductance of the shield, namely the first shield part <NUM> and the second shield part <NUM> electrically closed together thanks to the magnetized element <NUM> and the metallic element <NUM>, as closure elements, is greater than a conductance of the antenna <NUM>.

The shield allows, when the shield is electrically closed, shielding against an RF signal transmitted to the antenna <NUM> with an electromagnetic field strength that is included in a range between about <NUM>,<NUM> A/m and about <NUM>,<NUM> A/m. In such an electrically closed position, the shield prevents the RF chip <NUM> from communicating with any external CL reader.

Maintaining, in a closed position, the article allows generating a Faraday shield by electrically closing, based on the closure elements <NUM> and <NUM> provided on the first <NUM> and second <NUM> shield parts, the first <NUM> and second <NUM> shield parts.

Maintaining, in a closed position, the article allows preserving a flatness of its cover, its inner sheet(s) and/or its data page and therefore reducing a warpage issue or a risk to deform its cover, its inner sheet(s) and/or its data page.

The user of the article using the invention assembly may select to either authorize by opening the article or deny by closing the article access to the RF chip <NUM>.

<FIG> presents schematically the assembly <NUM> for shielding the RF chip <NUM> and an e-passport <NUM>, as a particular article, that is represented in a simplified manner.

Each sheet <NUM> is made in e.g., paper. Each sheet <NUM> is not electrically conductive. Each sheet <NUM> is attached to the e-passport <NUM> through a hinge (not visible on <FIG>).

The hinge allows attaching one or several sheets <NUM> and a data page that are included in the e-passport <NUM>.

The hinge may include e.g., filaments that cross each other to form a grid. The hinge is not electrically conductive. The hinge faces typically a folding area of the e-passport <NUM>.

The first shield part <NUM> and the second shield part <NUM> include, e.g., eight apertures <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM> and <NUM>, at the folding area between the first shield part <NUM> and the second shield part <NUM>.

A count of aperture(s) at the folding area between the first shield part <NUM> and the second shield part <NUM> may be greater than one without impacting the shielding efficiency in a closed position. Each aperture <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM> or <NUM> is bordered by at least one wire and/or at least one stripe. The wire(s) and/or the stripe(s) which border each aperture <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM> or <NUM> is(are) electrically conductive.

The second shield part <NUM> includes the aperture <NUM>. The aperture <NUM> faces at least <NUM>% of an area covered by the antenna <NUM>.

The strip <NUM> is preferably flexible, so as to be bent or curved onto the front side of the e-passport <NUM>.

The magnetized element <NUM> that is associated, through the strip <NUM>, with the second shield part <NUM> is electrically connectable to the corresponding metallic element <NUM>.

The magnetic and attractive force that is exerted by the magnetized element <NUM> may be equivalent to a weight of at least about <NUM> for the e-passport <NUM>, so as to close and maintain the e-passport <NUM> in an electrically closed position.

The e-passport <NUM> includes further, in the foreground, a hole <NUM>, the chip (not visible on <FIG>) and a plurality of wires <NUM> which are included in the antenna <NUM>.

The hole <NUM> allows accommodating the chip <NUM>. The chip <NUM> is connected, through two wires that are e.g., soldered to the module that is internally connected to the chip.
