Abstract: This disclosure provides systems, methods and apparatus for detecting the presence of an object or living being below a vehicle. In one aspect a wireless charging system for an electric vehicle is provided. The system includes a vehicle charging pad configured to wirelessly receive power from a base charging pad spaced from the vehicle charging pad. The system further includes a detection apparatus on a surface of the vehicle. The detection apparatus is configured to detect existence of a moving object within an exclusion zone underneath the vehicle. The detection apparatus includes at least one antenna assembly configured to transmit radiation and to receive radiation reflected from material within the exclusion zone. The at least one antenna assembly has a radiation pattern for at least one of the transmitted radiation and the received radiation, the radiation pattern having a maximum gain and having a first gain along a first line perpendicular to the surface less than half of the maximum gain on a linear scale.

Abstract: This disclosure provides systems, methods and apparatus for detecting foreign objects. In one aspect an apparatus for detecting a presence of an object is provided. The apparatus includes a resonant circuit having a resonant frequency. The resonant circuit includes a sense circuit including an electrically conductive structure. The apparatus further includes a coupling circuit coupled to the sense circuit. The apparatus further includes a detection circuit coupled to the sense circuit via the coupling circuit. The detection circuit is configured to detect the presence of the object in response to detecting a difference between a measured characteristic that depends on a frequency at which the resonant circuit is resonating and a corresponding characteristic that depends on the resonant frequency of the resonant circuit. The coupling circuit is configured to reduce a variation of the resonant frequency by the detection circuit in the absence of the object.
