Abstract
An electronic apparatus includes switch control circuitry configured to determine whether a received signal is for a power receiving operation or a data receiving operation based on a level of a frequency component of the received signal, select the power-reception operation or a data-transmission operation based on the determination, and switch to the power-reception operation or the data-transmission operation based on the selection.
Claims27
An electronic apparatus comprising:
- switch control circuitry configured to:
- determine whether a received signal is for a power receiving operation or a data receiving operation based on a comparison between a voltage of the received signal and a predetermined threshold voltage;
- select the power-reception operation or a data-transmission operation based on the determination;
- and
- switch to the power-reception operation or the data-transmission operation based on the selection.
An electronic apparatus comprising:
- switch control circuitry configured to:
- determine whether a received signal is for a power receiving operation or a data receiving operation;
- and
- select the power-reception operation or the data-transmission operation based on the determination,
- wherein the switch control circuitry includes:
- a first detection circuit configured to determine if a first frequency component of the received signal exceeds a first threshold;
- a second detection circuit configured to determine if a second frequency component of the received signal exceeds a second threshold, and
- wherein the switch control circuitry is configured to determine that the received signal is to be transmitted to:
- a power-reception operation section if the first detection circuit determines that the first frequency component meets the first threshold;
- and
- a data-transmission operation section if the second detection circuit determines that the second frequency component meets the second threshold.
A method of routing a received wireless signal comprising:
- receiving a signal wirelessly;
- routing the received signal to a power-reception operation section if a level of a first frequency component of the received signal meets a first threshold;
- and
- routing the received signal to a data-transmission operation section if a level of a second frequency component of the received signal meets a second threshold.
An electronic system comprising:
- a transmitter configured to wirelessly transmit a signal;
- and
- an electronic device wirelessly communicatively coupled to the transmitter, the electronic device including:
- switch control circuitry configured to:
- determine whether the transmitted signal is for a power receiving operation or a data receiving operation based on a comparison between a voltage of the transmitted signal and a predetermined threshold voltage;
- and
- select the power receiving operation or the data receiving operation based on the determination of the transmitted signal.
