Publication number: 20220103015Abstract: 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.Type: ApplicationFiled: July 28, 2021Publication date: March 31, 2022Inventors: Michael B. Nussbaum, Katherine I. Pregler, Liang Chen, Todd K. Moyer, Bingyao Sun

Patent number: 11166106Abstract: 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.Type: GrantFiled: June 1, 2020Date of Patent: November 2, 2021Assignee: APPLE INC.Inventors: Michael B. Nussbaum, Roderick B. Hogan, Todd K. Moyer
