    Abstract: Embodiments of methods and systems for operating a communications device that communicates via inductive coupling are described. In an embodiment, a method for operating a communications device that communicates via inductive coupling involves adjusting a configuration of the communications device in response to a clock signal that is synchronized to a received clock signal, obtaining information that corresponds to transmission current or power generated in response to the adjusted configuration, and quantifying a detuning condition in response to the obtained information. Other embodiments are also described.

    Abstract: Embodiments of methods and systems for operating a communications device are described. In one embodiment, a method for operating a communications device that communicates via inductive coupling involves adjusting a phase configuration of the communications device in response to at least one system or environmental parameter, modulating a carrier signal with the adjusted phase configuration using active load modulation (ALM), and transmitting the modulated carrier signal from the communications device for inductive coupling. In some embodiments, the at least one system or environmental parameter is selected from one or more of the following: a distance information, a geometric information, a system code, a technology code, a transmitter current and/or a transmitter power, a detuning condition, a quality factor and a resonant frequency of a resonant system.
