Abstract: Methods and systems are provided for a hinge knee system. A hinge knee system may comprise a femoral component; an insert; a tibial tray configured to be coupled to the insert; a tibial bushing configured to be disposed between the tibial tray and the insert; a poly locking screw configured to secure the tibial tray to the insert; a hinge box configured to be disposed between the femoral component and the insert; one or more cross-pin bushings configured to be disposed within the hinge box; a cross-pin configured to secure the hinge box to the femoral component; a hinge post configured to couple the hinge box to the tibial tray; and a hinge post set screw configured to secure the hinge box to the hinge post.

Abstract: A secured document, in the form of a booklet made up of at least one page that can be folded about a folding axis, includes a transponder provided with an electronic chip including memory for data storage and a transponder antenna. The secured document further includes two amplifier antennas, separate from the antenna of the transponder, arranged on pages of the booklet so that, in the open document position, one of the amplifier antennas amplifies the electromagnetic flux picked up by the antenna of the transponder to allow the document to communicate with a remote reader, and, in the closed document position, the amplifier antennas are configured so that the electromagnetic flux picked up by the antenna of the transponder is below a minimal threshold that allows the electronic chip to communicate with a remote reader.

Abstract: The invention relates to an antenna for a contactless smart card, arranged on an insert intended to be integrated in said smart card having a certain relative vertical or horizontal positioning tolerance T between the insert and the body of the card, said smart card being provided with an embossing area comprising lines of characters embossed in relief, at least one antenna coil being situated opposite the embossing area, wherein said coil comprises at least one pair of paths situated in the embossing area and connected in parallel, said paths being configured in such a way that at least one of same remains at least partially situated outside of the embossed character area whatever the relative position of the insert and the antenna of same allowed by the tolerance T.

Abstract: A contactless chip card intended to communicate with a chip card reader operating at a first resonant frequency includes a booster antenna provided with an inductive main antenna and with an inductive concentrator antenna, which antennae are connected in series or parallel with a capacitor. The inductances of the inductive main antenna and the inductive concentrator antenna and the capacitance of the capacitor are chosen on the one hand to obtain a second resonant frequency that is far enough from the frequency of the signal emitted by the reader to limit radiofrequency communication with the reader, and on the other hand so that the connection in parallel of a predetermined capacitance brings the resonant frequency of the card into the vicinity of said first resonant frequency of the signal emitted by said reader.

Abstract: The invention relates to a contactless chip card intended to communicate with a chip card reader operating at a resonant frequency F0?. The chip card includes a booster antenna provided with an inductive main antenna U and with an inductive concentrator antenna L2, which antennae are connected in series or parallel with a capacitor C, wherein the inductances of L1 and L2 and the capacitance of C are chosen on the one hand to obtain a resonant frequency F0 that is far enough from the frequency of the signal emitted by the reader to limit radiofrequency communication with the reader, and on the other hand so that the connection in parallel of a predetermined capacitance Cd brings the resonant frequency of the card into the vicinity of said frequency F0? of the signal emitted by said reader.

Abstract: An insert for a chip card includes a body provided with a cavity in which is inserted an electronic module provided with a microelectronic chip connected to an inductive or capacitive coupling. The body has a stack of layers at least a first layer of which comprises a first booster antenna and a second layer of which comprises a second booster antenna, the various booster antennas being coupled together inductively and/or capacitively, and at least one of the booster antennas being coupled inductively and/or capacitively with the coupling of the module. The body furthermore comprises at least one metal plate disposed between two layers of ferrite, the first and second booster antennae and the metallic plate being arranged in such a way that at least one of the two booster antennas and the electronic module remain coupled together inductively and/or capacitively, despite the presence of the metal plate.
