A system and method to detect a foreign object proximate to a source resonator that is part of a wireless energy transfer system. The wireless energy transfer system may be one used to wirelessly charge the batteries of an electric vehicle. Data from a visible light camera and a multiple zone temperature sensor are combined or fused to determine whether a foreign object, such a metallic object or an animal, is in the vicinity of, or in close proximity to, a source resonator. The system controls an electric current provided to the source resonator based on whether a foreign object is detected to reduce or inhibit energy emitted by the source resonator. The visible light camera may be a monochrome or color camera and the temperature sensor may be an infrared camera or a thermopile array.

An arrow for use in combination with an archery bow, is provided with airfoil structure on its shaft in the form of a cambered wing section to increase the flight and accuracy of the arrow. A pair of fletches at the trailing end of the shaft are circumferentially spaced from one another 120.degree. in order to provide desired flight stability for the arrow. An improved center shot bow is disclosed, having an oversized sight window and undersupporting arrow rest whereby to accommodate arrows with flight structure of a width greater than the diameter of the arrow shaft.
