    摘要: Techniques are disclosed involving reconfigurable coils. Such coils may be used in applications, including (but not limited to) wireless charging and near field communications (NFC). For instance, a reconfigurable coil may include a first conductive portion and a second conductive portion. Two or more configurations may be established. These configurations may correspond to particular current paths. For example, in a circular configuration, a path is provided having the same rotational sense in both first and second conductive portions. However, in a figure eight configuration, a path is provided having a first rotational sense in the first conductive portion and a second rotational sense in the second conductive portion. A switch coupled between these portions may set the coil's configuration. Configurations may be selected based on one or more operating conditions involving the coil.

    摘要: 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.
