Abstract:
Apparatus, system and method to provide switchable coils in a computing device, comprising: a plurality of electrically conductive coils to transfer electromagnetic energy; a sensor coupled to a processor, to select a coil from among the plurality of electrically conductive coils; a switch to energize the selected coil; and a switch controller coupled to the switch and to the processor. In some embodiments, the plurality of coils may comprise an inductive charging interface. Some embodiments may further include a communication interface between the processor to the plurality of electrically conductive coils, the plurality of coils comprising an interface for near-field communications (NFC). The antenna coils may be arranged to provide improved NFC coverage when the computing device is in a respective predetermined physical configuration. Sensors may be used to detect the configuration and switch NFC communications to use a preferred antenna coil for the detected configuration.
