Abstract: The proposed technique relates to cash register implemented by means of a tablet type digital touchpad device (400). The digital touchpad device (400) is fixed to a main module (100) that comprises: a central unit (102); an interchangeable support (107) adapted to maintaining said digital touchpad device (400); a hinged arm (110), of which one of the extremities, called a first extremity, is linked by a first pivot link (111) to said central unit (102), and of which the other extremity, called a second extremity, is linked by a second pivot link (112) to a receiving plate to which said interchangeable support (107) is fixed. The proposed cash register is modular, and it optionally comprises an optical reader module and/or a payment module on which a payment terminal is positioned.

Abstract: A payment device is provided, which is to be paired with a communication device in order to form an electronic payment terminal. The payment device includes an upper half-shell and a lower half-shell, which includes a surface for attaching a modular interface for pairing the communication device and which includes a longitudinally extending slot. The lower half-shell further includes, within the slot, an opening which enables a magnetic reading head to pass therethrough. Beneath the attachment surface, an electronic circuit card is arranged laterally relative to the magnetic reading head such that the electronic circuit card prevents the insertion of a fraudulent device into the payment device.

Abstract: An electronic payment device is provided, which includes a chip card reader. The device has a housing able to receive and hold a portable telephone, a connector for connection with the portable telephone, and a data processor able to receive information relating to a payment and to exchange data with a remote server via a telephone communication implemented by said portable telephone.

Abstract: An axisymmetric, converging-diverging and swiveling exhaust nozzle includes converging flaps (3) driven by an axially displaceable drive ring (7). The diverging flaps (15) are connected by linkrods (20) to a pivoting ring (21). The pivoting ring (21) is mounted in swiveling manner on a spherical segment (30) fixedly joined to the structure (13). In an embodiment variation, the spherical segment (30) is mounted by a sliding connection on the stationary structure. A rotation-blocking system (33) precludes the rotation of the spherical segment (30) about the axis X of the turbojet engine.

Abstract: An axisymmetric, converging-diverging exhaust nozzle swiveled by a guided vectoring ring (20). The guides comprise three axial apertures (44) which are each located in a base firmly joined to relatively fixed structure and of which the center planes intersect along the longitudinal axis of the turbojet-engine. The side walls (45) of the apertures (43) guide three mutually equidistant spherical rollers (41) fastened to radial stubs (40) firmly affixed to the vectoring ring (20).

Abstract: An axisymmetric, converging-diverging turbojet-engine exhaust nozzle for jet deflection. The diverging flaps are connected by linkrods to a vectoring ring (13). The vectoring ring (13) is driven by linear actuators (20) anchored in the stationary structure (2). The linear actuators (20) are connected by a swivel (22) to the vectoring ring (13) and are affixed to the stationary structure (2) to absorb the tangential loads applied by the exhaust gases on the diverging flaps and to allow positioning the vectoring ring (13). Preferably the linear actuator (20) is connected by a sheath (25) to the vectoring ring (13), the sheath (25) slidable on the actuator case (26) and being displaceable in a radial plane passing through the turbojet-engine's axis.

Abstract: The invention relates to a wide-vectoring, axisymmetric turbojet-engine exhaust nozzle including vectoring structure (12) supporting a plurality of converging flaps (21). The vectoring structure is mounted on the downstream end of an exhaust housing (2) by means of an intermediate ring (9) which is pivotable about a first axis relative to the exhaust housing (2) and further about a second axis perpendicular to the first axis and relative to the vectoring structure (12). The converging flaps (21) hinge on the downstream end of the vectoring structure (12). A single drive ring (27) controlled by three linear actuators (28) and linked by linkrods (24) to the converging flaps (21) controls the tipping of the vectoring structure (12) and the kinematics of the flaps (21).

Abstract: The invention relates to a regulation system for an asynchroNOus motor by field oriented control, reacting to a torque set value (T) and a flux set value (&phgr;). The flux set value is supplied from the torque set value by an operator carrying out first order low pass filtering (40) and calculating the square root (42) of the result of the filtering.
