Claim 0:
1. A power transmitter device comprising:
a power transfer circuit,
wherein the power transfer circuit comprises a power transfer coil,
wherein the power transfer coil is arranged to generate a power transfer signal during at least one power transfer interval(s),
wherein the at least one power transfer interval(s) is a portion of at least one repeating frame(s),
wherein the at least one repeating frame(s) comprises the at least one power transfer interval(s), at least one object detection interval(s) and at least one communication interval(s);

a communicator circuit, wherein the communicator circuit is arranged to communicate with a power receiver via a communication signal;
a communication resonance circuit,
wherein the communication resonance circuit comprises a communication antenna,
wherein the communication antenna is arranged to transmit and receive the communication signal,
wherein the communication resonance circuit is arranged to provide a resonance at a first resonance frequency for the communicator circuit; and

a controller circuit,
wherein the controller circuit is arranged to adapt the communication resonance circuit so as to not provide the resonance for the communicator circuit during the at least one object detection interval(s),
wherein the controller circuit is arranged to adapt the communication resonance circuit so as to provide the resonance for the communicator circuit during the at least one communication interval(s).
