Abstract: A transmitter device for an inductive energy transfer system can include a DC-to-AC converter operably connected to a transmitter coil, a first capacitor connected between the transmitter coil and one output terminal of the DC-to-AC converter, and a second capacitor connected between the transmitter coil and another output terminal of the DC-to-AC converter. One or more capacitive shields can be positioned between the transmitter coil and an interface surface of the transmitter device. A receiver device can include a touch sensing device, an AC-to-DC converter operably connected to a receiver coil, a first capacitor connected between the receiver coil and one output terminal of the AC-to-DC converter, and a second capacitor connected between the receiver coil and another output terminal of the AC-to-DC converter. One or more capacitive shields can be positioned between the receiver coil and an interface surface of the receiver device.

Abstract: Circuits, methods, and apparatus that may compensate for an incompatibility between connection detection schemes used by different interface circuits for different connector receptacles. One example may provide an active pull-down that normally provides a pull-down resistor and provides an open circuit for a period of time following a disconnection of an interface from a cable.
