Abstract:
A wireless power transfer system that transmits electrical power from an electrical power supply to an electrical load using a source transducer and a capture transducer. The wireless power transfer system may be part of a wireless charging system for an electric vehicle. The source resonator coil in the source transducer and the capture resonator coil in the capture transducer are substantially identical and are interchangeable. The structures that hold the resonators in the transducers and the plates that provide a ground plane for the resonators in the source transducer and the capture transducer are also substantially identical and are interchangeable. Each resonator is formed of a carrier-winder, or bobbin, that has two substantially identical and interchangeable halves enclosing a magnetic core and is wound with a wire coil.
Abstract:
A tool configured to tension an elongate cable tie around a wire cable bundle and sever a portion of a tie tail from the cable tie. This tool includes a pistol-shaped housing having a handle portion and a barrel portion. A slide mechanism disposed within the barrel portion comprises a gripper mechanism configured to grip a tail of the cable tie and a slide configured to move the gripper mechanism in a direction toward an end of the barrel portion and pull the tail of the cable tie through the tie head, thereby tightening the cable tie around the wire cable bundle. The tool also includes a tensioning mechanism that is configured to halt application of the tension to the cable tie when the tension applied by the slide mechanism reaches a predetermined tension threshold and a cutoff mechanism configured to sever the tie tail from the cable tie.
Abstract:
A non-contact charging device for charging a battery in a vehicle includes a source resonator, and a foreign object detector. The source resonator is configured to transfer electrical energy to a capture resonator in a vehicle. The foreign object detector is configured to detect a foreign object proximate to the source resonator. The foreign object detector includes a vertical antenna configured to detect a foreign object above the source resonator, and a horizontal antenna configured to detect a foreign object beside the source resonator.
