Abstract: The invention relates to an osteosynthesis assembly formed by a plate and at least one screw provided with a head, designed to maintain said plate by crossing through an orifice of said plate to fasten it to a bone, said plate having as many orifices (2) as there are screws, characterized in that: at least one of said orifices of said plate has, over at least a portion of its periphery, a metal, ceramic or polymer collar, at which the nominal diameter of the orifice is reduced to a value below said nominal diameter; said screw designed to cross through said orifice has a conical or curved under-head threading; the collar and the thread bottom of the under-head threading have a tightening of at least 0.01 mm if the collar is made from metal or ceramic and at least 0.05 mm if the collar is made from polymer, so as to create a hard spot toward the end of the placement of the screw, said hard spot remaining after the screw has been placed.

Abstract: The document includes a support (10) provided with at least one first (12) and second (14) parts that can move relative to one another, the support including an electronic microcircuit (3) and contactless coupling members (2) electrically connected to the electronic microcircuit (3), and capable of being coupled to an external reading station (5) for establishing a contactless communications with the latter (5). The support also includes detecting elements (20) capable of detecting the relative proximity of the first and second parts independent of the contactless coupling members (2), and securing elements (30) connected to the detecting elements (20) and capable of inhibiting and/or authorizing the activation of the contactless communication according to the relative proximity of the first and second parts thus detected.

Abstract: The invention relates to a flexible data support, comprising a support with at least first and second sheets (11, 12A, 12B, 12C) which can pivot relative to each other about an axis (P) along the edges of said sheets and a contactless chip housed in said support and comprising an electronic circuit (IC) and coupling elements (A1, A2) connected to said electronic circuit distributed about the first and second sheets which may be electromagnetically coupled to an external reading station. The electronic circuit comprises an information exchange section for exchange of information with the exterior, characterised in that said support is provided with a test device for verification by means of signals emitted by the coupling elements of a geometrical condition of the angular configuration of the first and second sheets and to generate, as function of the result of said test, a signal authorizing or preventing the activation of the exchange section of the electronic circuit.

Abstract: The invention concerns a microcircuit card comprising means (RX) for receiving a command and means for modifying at least one performance of the card capable of being implemented after a step of personalization of the card.

Abstract: The invention relates to a plate (2) with a slot (7), adjacent to at least one hole (4, 6) therein, which traverses the whole of said plate and which extends along said hole (4, 6) on a part of the perimeter of said hole (4, 6). The hole (4, 6) and slot (7) thus define a band of material (8) between them which is flexibly elastic. The band (8) comprises locking means (9) on the edge thereof defining the hole (4, 6), which project towards the interior of the hole (4, 6). The object (3), for placement in said hole (4, 6), comprises complementary locking means (10) which, when said object (3) is engaged in said hole (4, 6) come into engagement with the locking means (9) on the band of material (8) such as to connect said object (3) to the plate (2) or to fix said plate (2) to a bone.

Abstract: A system for securely storing CD-ROM data including a CD-ROM having data encrypted at least in part with a cryptographic algorithm having a decryption key K, a CD-ROM drive for receiving the CD-ROM, an electronic decryption microcircuit embedded in the CD-ROM, means for exchanging information between the CD-ROM drive and the electronic decryption microcircuit embedded in the CD-ROM, and a chip card containing at least a part K1 of the decryption key K, any remaining part K2 of the decryption key K being in the electronic decryption microcircuit embedded in the CD-ROM. Also included is a secure means for securely exchanging information between the chip card and the electronic microcircuit embedded in the CD-ROM. Further, the electronic decryption microcircuit embedded in the CD-ROM includes an antenna which provides, without the presence of contact, both an electrical power supply to the decryption microcircuit from an external source and exchanges of information with the external source.
