Abstract: The invention concerns an electronic module (11) with double communication interface, in particular for a chip card, the said module comprising firstly a substrate (27) provided with an electrical contact terminal block (17) allowing functioning by contact with the contacts of a reader, and secondly comprising an antenna comprising at least one turn (13) and whose terminals are connected to the terminals of a microelectronic chip situated on one face of the module (11). This module (11) is characterised in that the antenna turns (13) are situated substantially outside the area covered by the electrical contacts (17), so that the electrical contacts of the terminal block do not constitute electromagnetic shielding for the signals intended for the antenna. The invention applies in particular to the production of chip cards with double communication interface with contact and without contact.

Abstract: A secure document, in particular an electronic passport, includes a support equipped, on the one hand, with active security devices having a microcircuit connected to an antenna that can produce an electromagnetic response when it passes through the electromagnetic field of a contactless reader designed to query the identity document. The support is equipped, on the other hand, with passive security devices selected so as to have electrical characteristics, in particular inductive, capacitive and resistive, that are suitable for amplifying the electromagnetic response of the active security devices to make it go beyond a threshold that allows the secure document to be identified when it is placed in the electromagnetic field of a contactless reader. The invention has a useful application in national programs to issue passports with increased security.

Abstract: The invention relates to a method of detecting a fire in a wooded area. Some trees in the area are provided with a fire sensor having a radiofrequency emitter able to emit information for identifying and/or locating each sensor, according to a grid of the area to be monitored. At each fire sensor, the fire absent or fire present state is detected A fire sensor emits an alert signal to a monitoring post if a fire is present in the vicinity of the sensor. The alert signal contains information for identifying and/or locating the sensor. The alert signal is transmitted from the monitoring post to a fire brigade by means of a long-range radiofrequency link.

Abstract: An adapter for a portable integrated circuit device of the chip card variety has a reduced format in comparison with the standard mini-card format. The device with a reduced format includes a body on which a microcircuit defining contact pads is disposed. A support which has a standard mini-card format is provided with a cavity having the dimensions of the device with a reduced format. The device is detachably fixed in the cavity. The cavity is located in the support in such a way that the location of the contact pads of the microcircuit of the device with a reduced format coincides with the standardization location of the contact pads of a microcircuit having a standard format mini-card.

Abstract: A portable integrated circuit device has a supporting body and a detachable mini-card bearing an integrated circuit. The mini-card is disposed on one end of the supporting body which has an elongated shape. The invention can be used for SIM cards in new generation mobile telephones.
