    Abstract: A magnetic coil suitable for wireless power transfer comprises a layer of magnetically-permeable material and plural conductors that follow respective convoluted paths relative to the layer of magnetically-permeable material to form respective inductors. In use, the conductors have substantially equalized inductances based on the convoluted paths and interaction with the magnetically-permeable material. One way of achieving this is to place the conductors such that the overall proximity of the conductors to the layer of magnetically-permeable material along their respective lengths is substantially equal. In this way, the conductors are positioned substantially symmetrically with respect to the layer of magnetically-permeable material, such that an average distance of each individual section of the conductors proximate to the permeable layer is equal.

    Abstract: Techniques for providing radio-frequency signals to a region of interest for a living-objection protection (LOP) system are provided. An example base wireless power transfer system includes a power-coupling element and a power transfer circuitry configured to provide energy to the power-coupling element to produce a magnetic field, and a living-object protection subsystem including an antenna configured to transmit a first radio-frequency (RF) signal with a main beam directed away from the power transfer circuitry and to receive a second RF signal, the antenna including a radiating element and a reflector with the reflector being disposed between the radiating element and the power transfer circuitry and comprising a metal sheet disposed over an area, the metal sheet defining at least one opening within the area and between the radiating element and the power transfer circuitry.

    Abstract: Apparatus, system, and method for adaptive charging compliance control are disclosed. A charging station wirelessly charges a vehicle in compliance with emissions regulations. A controller in the charging station obtains information regarding the characteristics of an incoming vehicle and accesses a maximum regulation-compliant power level database based on the vehicle information obtained and determines conditions of the vehicle parked at the charging station. The controller determines and delivers the maximum power level to wirelessly charge the vehicle while maintaining the level of field emissions no greater than the regulatory limit.

    Abstract: This disclosure provides systems, methods and apparatus for detecting a presence of an object. In one aspect an apparatus for detecting a presence of an object is provided. The apparatus includes a sense coil formed from a conductor having a predetermined shape configured to attenuate currents induced in the conductor by an external time-varying magnetic field. The sense coil has an electrical characteristic that varies as a function of the presence of the object. The apparatus comprises a detection circuit coupled to the sense coil and configured to detect the presence of the object in response to detecting a difference between a measured value of the electrical characteristic and a reference value for the electrical characteristic. The reference value for the electrical characteristic is substantially the same as the measured value of the electrical characteristic in the absence of the object over at least a portion of the sense coil.
