1. A method comprising:
- transmitting inductively, by an inductive power supply to at least one device, a poll signal;
receiving inductively, by the inductive power supply, a signal received from the at least one device in response to the poll signal;
determining whether the inductively received signal comprises a modulated data signal; and
adjusting a power of a transmission signal produced by the inductive power supply on the basis of the modulated data signal,wherein the inductive power supply transmits inductively, on the basis of the modulated data signal, a transmission signal with a power higher, lower, or a combination thereof than the poll signal.

Abstract
There is provided a method comprising transmitting inductively a first signal, receiving inductively a second signal in response to the first signal, determining whether the inductively received signal comprises a modulation, and adjusting a power of the transmitted signal on the basis of a modulation of the received signal.

6. An apparatus comprising:
-
a transmitter configured to transmit inductively a poll signal; a receiver configured to inductively receive a modulated data signal in response to the poll signal; a controller configured to determine whether a received signal comprises a modulation; and a controller configured to adjust a power of the transmitted signal on the basis of a modulation of the received signal, wherein the transmitter is configured to inductively transmit a third signal, on the basis of the received signal comprising a modulation, wherein the third signal has a power higher than the poll signal. - View Dependent Claims (7, 8, 9, 10, 11)
