| 20080198078 | Adjusting Resonance Frequency by Adjusting Distributed Inter-Turn Capacity - The invention concerns a method for adjusting frequency tuning of a resonant circuit with turns having a regular spacing generating stray inter-turn capacity. The adjusting of the frequency tuning of the resonant circuit is performed, at the level of the stray inter-turn capacity, by varying the regular spacing of adjacent turns on at least one zone of the antenna. The invention uses this adjusting method for producing an adjusted antenna for a resonant circuit, the resonant circuit and a non-contact product. The invention concerns a device programmed for antenna production and/or definition. | 08-21-2008 |
| 20080297315 | Inductive Coupling Exchange in a Portable Intelligent Object With Central and Peripheral Circuits - A portable intelligent object has first and second communication interfaces with a station. The first communication interface can send and/or receive data by means of inductive coupling with the station. The object also has an integrated peripheral circuit. All of the data exchanged between the peripheral circuit and the central circuit passes through the station. | 12-04-2008 |
| 20090271972 | Method for Producing a Contactless Transponder by Stitching a Contactless Module to an Antenna, and Transponder Obtained - A contactless transponder includes an antenna and an electronic module placed on a substrate and connected to the antenna by a conducting wire passing through the contact pads in the form of at least one stitch. The module is produced as a single block, having at least one integrated circuit and contact pads. The module is transferred to the substrate before connection to the antenna. | 11-05-2009 |
| 20100213261 | METHOD FOR OPTIMIZED READING OF CERTIFICATES HAVING RADIOFREQUENCY TRANSPONDERS, SET OF SUITABLE CERTIFICATES AND DOCUMENT CONTAINING THE SAME - The invention relates to a method for reading electronic certificates positioned in a document, each certificate comprising a support bearing an antenna linked to a microcircuit. The document has sheets of a determined format articulated around a hinge. The antennas are dimensioned to a format less than that of a half-sheet. The certificates are arranged at most in pairs on a sheet so that the antennas are spaced apart along a longitudinal axis of the sheet. The invention also relates to a set of certificates and the document containing the certificates. | 08-26-2010 |
