  • Publication number: 20220103015
    Abstract: A wireless power transfer system can include a wireless power transmitter (PTx) and a wireless power receiver (PRx). The PTx can include a transmit coil driven by an inverter configured to receive an input DC voltage and provide an output AC voltage as a plurality of bursts. The PRx can include a receiver coil magnetically coupled to the transmit coil such that the bursts induce a corresponding AC voltage and a rectifier configured to receive the AC voltage and output a DC voltage to a load. The PRx can also include burst request pulse generation circuitry configured to operate the rectifier so as to deliver a burst request pulse to the PTx via magnetic coupling between coils. The PTx can further include inverter control circuitry configured to sense the burst request pulse and, in response thereto, trigger the inverter to deliver an AC voltage burst.

  • Patent number: 11166106
    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.

  • Patent number: 10879721
    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.

  • Patent number: 10790699
    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.
