Abstract: An approach for preventing unauthorized card transactions is presented. An authorization record including an authorized geographic location and an authorized period of time is received from a travel reservation system (TRS) and stored to dynamically update a profile table that stores other authorization records. The authorization record identifies an itinerary specified by travel booking(s) purchased via the TRS using a debit or credit card. The itinerary specifies that the cardholder is scheduled to be in the authorized geographic location for the authorized period of time. In response to receiving a request for an authorization of a card transaction, a location and date associated with the card transaction are retrieved from the request. The card transaction is rejected based on a determination that the retrieved location is not within authorized geographic locations included in the stored authorization records that have authorized time periods that include the retrieved date.

Abstract: A method and system of position determination using image deformation is provided. One implementation involves storing an actual tag in a reference data module, receiving an image of a visual tag, the image captured by an image capturing device, comparing properties of the visual tag with properties of the actual tag; and based the comparison, determining a position of the image capturing device relative to the visual tag.

Abstract: An antenna (3) charged by a diode (4) is arranged at each of the points of a surface (30). The source (1) and a collecting antenna (5) are arranged on the same side of this surface, in the vicinity of each other. A layer (32) of absorbent material is provided, one face of which fits the shape of the surface (30) and is arranged on the side of said surface (30) opposite that of the source (1) and of the collecting antenna (5). An addressing circuit (33) of the diodes (4) which fits the shape of the other face of the absorbent layer (32) is connected, via connections which pass through said layer (32) perpendicular to the surface (30), to each of the diodes (4). The use of the modulated diffusion method permits the measurement of the near field radiated by a transmission antenna or diffracted by an object illuminated by a microwave radiation.

Abstract: A transmitting antenna radiates a micro-wave field through an opening in the form of a rectangular wave-guide applied against the separation surface between a first medium, in which it is located, and a second medium, in which an object is buried. The micro-wave radiation reflected by the object is collected through the opening of a receiving antenna, also in the form of a rectangular wave-guide, applied against the radiating opening of the transmitting antenna. The collected radiation is measured at a series of points by means of pinpoint antennae located in the collecting opening. Thanks to the antennae arrangement, the collected radiation can be used as such, without having to subtract therefrom the result of a reference measurement. The invention can be used particularly to obtain, non destructively, images of metal bars buried in reinforced concrete.
