Abstract:
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.
Abstract:
A method to construct a tape wrapped unshielded twisted pair (UTP) cable is provided. The method includes the step of twisting a first wire and a second wire together to form a twisted pair. The method further includes the step of wrapping tape around the twisted pair with an effective amount of tension on the tape such that a separation distance between the first wire and second wire does not substantially vary along the length of the twisted pair.
