An apparatus, system and method of a resonator device with an adjustable capacitor for allowing the resonance frequency of the resonator device to continue to be matched to the Larmor frequency of the MRI system. In an initial state a route of data from a mobile communication terminal M to a CN 8, which is a communication partner, is a route R5. The wireless communication circuitry may be configured to enable communication between the protective case and one or more remote communication devices via a short range network. A locally resolved image signal is determined for each of the intermediate signals, G2) by applying a Fourier transformation to the particular intermediate signal, G2). A comparator receives the reference voltage and the voltage produced by the eFuse cell. In one demonstrative embodiment of the invention, the method may include synchronizing transmission of first and second data frames to be received by first and second wireless stations, respectively, such that the transmissions of the first and second data frames end substantially simultaneously.
