Title (EN) POWER MANAGEMENT IN AN ELECTROMAGNETIC TRANSPONDER
(FR) GESTION DE PUISSANCE DANS UN TRANSPONDEUR ELECTROMAGNETIQUE
Abstract: front page image
(EN)The invention relates to a method for controlling the power in an electromagnetic transponder in the field of a terminal, said method comprising the following steps: the consumption of the circuits of the transponder is evaluated; if this consumption is lower than a certain threshold, the current coupling factor (k) between the transponder and the terminal is evaluated; and the consumption of the transponder is increased (52) or a discordance of an oscillating circuit of the transponder is generated, depending on the current coupling.
(FR)L'invention concerne un procédé de gestion de la puissance dans un transpondeur électromagnétique dans le champ d'un terminal, comportant les étapes suivantes : évaluer (40) la consommation des circuits du transpondeur; et si cette consommation est inférieure à un seuil, évaluer le facteur de couplage courant (k) entre le transpondeur et le terminal et, en fonction du couplage courant : provoquer (52) une augmentation de la consommation du transpondeur ou provoquer (50) un désaccord d'un circuit oscillant du transpondeur.
