20100253532 | Method of Locating an Emitting Handheld Device and Man/Machine Interface System Implementing Such a Method - A method of locating a handheld device emitting an electric field and/or magnetic field includes defining a reference area, arranging at least one electric field and/or magnetic field probe proximate to or inside the reference area, arranging the handheld device within the reference area, receiving from the probe a detection signal of the electric field and/or magnetic field emitted by the handheld device, and analyzing the detection signal supplied by the probe and determining therefrom the location of the handheld device within the reference area. Embodiments of the invention are applicable to the performance of an interactive action, which is initiated depending upon the location of the handheld device within the reference area. | 10-07-2010 |
20130183897 | APPARATUS COMPRISING INDUCTIVE COUPLING COMMUNICATION MEANS - An apparatus including inductive coupling communication circuitry configured to communicate in peer-to-peer mode with an identical apparatus includes an antenna coil presenting, relative to a longitudinal median or a transversal median axis of the antenna coil, an asymmetry corresponding to a coverage rate less than or equal to 0.6 if the antenna coil comprises 4 or more loops, less than or equal to 0.7 if the antenna coil comprises 3 loops, or less than or equal to 0.8 if the antenna coil comprises 1 or 2 loops. | 07-18-2013 |
20130288599 | METHOD AND DEVICE FOR MODULATING AN ACTIVE LOAD WITH DAMPING OF AUTO OSCILLATION - A method for sending data by inductive coupling includes: extracting an antenna signal from an antenna circuit, extracting from the antenna signal a first periodic signal, producing a second periodic signal by way of a synchronous oscillator, placing the oscillator in a free oscillation mode and applying to the antenna circuit the second periodic signal, modifying the impedance of the antenna circuit, restoring the amplitude of the antenna signal, then resynchronizing the oscillator on the first periodic signal. | 10-31-2013 |
