Abstract: A method for determining spatial coordinates of a source causing a dispersion effect in a domain, the dispersion effect being approximated by a system of partial differential equations, the method including computer-implemented steps, of obtaining measurements each quantifying at a point in space in the domain and at a given time a state variable modeled by the system of partial differential equations at the point and at the time, and of iteratively minimizing differences between the measurements and the computations of the system of equations to locate a position of the source. The system of equations is expressed in terms of finite differences generated by radial basis functions, the system of equations being solved in a least-squares context, using a least-squares solver, the system of equations having been subject to adjoint quadratic solution with radial basis functions chosen from polyharmonic-spline functions, inverse-multiquadric functions, or Gaussian functions.

Abstract: A system for protecting an input device. The system includes a pressurizing device and a printed circuit board having a false key. The pressurizing device includes a tube for receiving a flexible pressurizing element. A spacer of a predetermined length is disposed at a bottom of the tube.

Abstract: A fixed electronic terminal including at least one location intended to reversibly receive an electronic autonomy management system of the terminal.

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: 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.
