  • Patent number: 11904712
    Abstract: Foreign objects impinging on a ground transceiver assembly (GTA) of a wireless power transfer (WPT) station are detected using a two-stage foreign object detection system. In a first stage, at least one camera is positioned to observe a charging position of the GTA and an area surrounding the charging position. In a second stage, an impedance measurement circuit measures an impedance of a wireless power transfer coil of the GTA. An imaging processor analyzes images from the at least one camera to identify changes or features indicative of introduction of a foreign object onto an exposed surface of the GTA or in the area surrounding the charging position. A foreign object detection (FOD) controller triggers an impedance inspection of the GTA by the impedance measurement circuit and initiates a failsafe operation when movement of an object crossing into or over the charging position is detected.

  • Patent number: 11784511
    Abstract: A personal electronic device (e.g., a tablet computer) may be configured to wirelessly charge an accessory (e.g., a stylus) through a display face of the device. At least a portion of the display face may be transparent to facilitate display viewing. A wireless charging assembly disposed within the enclosure may include a core having one or more windings disposed thereon, which may be configured to generate a magnetic flux above the display face to couple to the accessory. The core may be a pot core, a modified pot core, or may have another shape, such as a PQ core. The one or more windings may be disposed on one or more posts of a pot core, or additionally or alternatively, may be disposed on another portion of the core. A metallic shield may be disposed about the wireless charging assembly, thereby surrounding multiple sides of the wireless charging assembly.

  • Patent number: 11780438
    Abstract: A motor vehicle having a combustion engine for vehicle propulsion can be automatically stopped when engine propulsion is not needed, such as during a gliding condition when the vehicle is coasting down to a slower speed (e.g., stopping) or down an incline. The engine is automatically restarted as needed. To ensure a capacity of a battery or other electrical storage device to support nominal operation of electrical loads (including a starter motor for restarting the engine) during an Auto Stop event, predicted future states of a vehicle battery are determined using a battery state of function (SOF) in response to load transients that may need to be supported.
