Abstract

A method for detecting receivers includes a step of detecting a receiver, in which step a general controller detects an adjustable receiver when a general antenna receives a secondary wave emitted by the adjustable receiver, followed by a reconfiguration step in which the general controller commands a controller of the detected adjustable receiver to switch to an interaction mode in which the impedance of the adjustable receiver is alternated between a first configuration impedance and a second configuration impedance in order to detect other receivers. The reconfiguration step is of a duration that is an order of magnitude higher than the duration of each alternation of the first and second configuration impedances.

Abstract

A method for detecting receivers comprises a step of detecting a receiver, in which step a global controller detects an adjustable receiver when a global antenna receives a secondary wave transmitted by the adjustable receiver, followed by a reconfiguring step in which the global controller commands a controller of the detected adjustable receiver to pass to an interaction mode in which the impedance of the adjustable receiver is alternated between a first configuration impedance and a second configuration impedance in order to detect other receivers. The reconfiguring step is of a duration of an order of magnitude higher than the duration of each alternation of the first and second configuration impedances.
