Abstract: A detachable headband for a headphone system can incorporate a headband identification circuit that stores or encodes a headband identification parameter value. When the headband becomes attached to an ear cup, the headband can transmit the headband identification parameter value to the ear cup.

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: A thermal management system for an electromagnetic induction-power transfer system. The system may include a charging apparatus including a housing that defines an interface surface. An accessory or induction-power consuming apparatus may be positioned proximate to the interface surface. The housing of the charging apparatus may include a power source and a power-transferring coil coupled to the power source and positioned below the interface surface. A thermal mass may be positioned within the housing and spaced apart from the interface surface. The housing may include a thermal path that is configured to conduct heat from the interface surface to the thermal mass.

Abstract: An electronic device may have control circuitry and input-output components. The input-output components may include audio components, sensors, and other devices. A proximity sensor may supply the control circuitry with proximity sensor data. The control circuitry may adjust the audio components or take other suitable action in response to proximity sensor readings from the proximity sensor. The proximity sensor may have a light source such as an infrared laser diode and a light detector that measures a reflected portion of infrared light pulses emitted by the infrared laser diode. The control circuitry may include circuitry for safely producing pulses of emitted light with the light source. This circuitry may include a signal generator that produces ramped pulses, a differentiator that differentiates the ramped pulses to produce differentiated pulses, and an output driver that produces current pulses for the light source based on the differentiated pulses.

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: 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.

At least four rectification elements are coupled to each other in a diode bridge configuration, where an input of the diode bridge configuration is coupled to the dc input circuit to receive the dc input voltage. At least one of the rectification elements includes a transistor. A decision circuit indicates, as a function of one of collector current and emitter current of the transistor, that the received dc input voltage has normal or reversed polarity.
