Abstract: An electronic device includes a housing coupled to a display window, a battery and a plurality of inductive charging transmit coils coupled to the battery. The plurality of inductive charging coils are positioned within the enclosure to generate an inductive charging region that extends through the display window and across at least a portion of an exterior of the display window. Sensing circuitry is configured to sense a position of a stylus at the display window and a processor is configured to selectively engage and disengage one or more of the plurality of inductive charging transmit coils based on the sensed position of the stylus. The stylus receives power when it is positioned within the inductive charging window.

Abstract: A hearable has an audio amplifier circuit coupled to a speaker as a load. The amplifier circuit has current source drive, which attenuates electromagnetically coupled noise of the speaker. In other instances, the amplifier circuit has a first amplifier mode and a second amplifier mode, wherein in the first amplifier mode the amplifier circuit becomes configured to drive the speaker as a voltage source, and in the second amplifier mode the amplifier circuit becomes configured to drive the speaker as a current source. Control logic varies the amplifier circuit between i) the first amplifier mode for larger amplitudes of the audio signal, and ii) the second amplifier mode for smaller amplitudes of the audio signal. Other aspects are also described and claimed.

Abstract: An inductive charging system can include a transmitter device and a receiver device. The transmitter device may be adapted to detect when a receiver coil in the receiver device is coupled to a transmitter coil in the transmitter device. For example, the current input into a DC-to-AC converter in the transmitter device can be measured and coil coupling detected when the current equals or exceeds a threshold value.

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: Power management and power transfer systems within the transmit and receive portions of an inductive charging system. An inductive charging system may include an inductive charging station to transmit power and a portable electronic device to receive power. Embodiments may take the form of power transfer systems within an inductive charging station including load-based transmit frequency adjustments. Embodiments may also take the form of power management systems within portable electronic devices which conserve power by disconnecting circuits from ground when those circuits are in an idle state.

Abstract: A wireless transmitter device is configurable and operable to transfer energy to multiple receiver devices at the same time. The transmitter device is configured to enable one or more sections of a charging surface to transfer energy by selectively choosing one or more conductive traces in the transmitter device based on the position of the receiver device on the charging surface. The size and shape of each section of the charging surface that is used to transfer energy to a receiver device can change dynamically based on each receiver device. Additionally, the process of transferring energy to each receiver device may be adjusted during energy transfer based on conditions specific to each receiver device.
