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.

Receiver detection system comprising:
- an adjustable receiver,
- a general antenna suitable for emitting a primary wave, and for receiving a secondary wave emitted by the adjustable receiver in response to reception of the primary wave,
- a general controller connected to the general antenna, the general controller being suitable for commanding the emission of the primary wave and for detecting the adjustable receiver by means of the secondary wave received by the general antenna,
- wherein the adjustable receiver further comprises:
- a receiver antenna suitable for emitting the secondary wave;
- a receiver controller connected to the receiver antenna, the receiver controller being suitable for commanding the emission of the secondary wave by the receiver antenna and for detecting the primary wave received by the receiver antenna,
- the adjustable receiver having a modifiable impedance in order to modify the manner in which the primary wave is reflected and/or transmitted by the receiver antenna as a secondary wave,
- the system being configured such that, when the adjustable receiver is detected by the general controller, the general controller commands the receiver controller to switch from a detection mode to an interaction mode,
- in detection mode, the adjustable receiver has a base impedance,
- in interaction mode, 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 interaction mode being of a duration that is an order of magnitude higher than the duration of each alternation of the first and second configuration impedances.
Adjustable receiver comprising:
- an antenna suitable for emitting a secondary wave in response to receiving a primary wave and for receiving a general control wave;
- and
- a controller connected to the antenna, the controller being suitable for commanding the emission of the secondary wave and for detecting the primary wave received and the general control wave,
- the adjustable receiver having a modifiable impedance thus influencing the secondary wave emitted,
- the adjustable receiver having a detection mode and an interaction mode, the adjustable receiver switching from detection mode to interaction mode according to the general control wave received,

- in interaction mode, the impedance of the adjustable receiver is adapted to alternate between a first configuration impedance and a second configuration impedance in order to detect other receivers, the interaction mode being of a duration that is an order of magnitude higher than the duration of each alternation of the first and second configuration impedances.
Method for detecting receivers, by a detection system comprising an adjustable receiver and a general antenna, wherein the general antenna is connected to a general controller, the method comprising:
