Abstract: A power mitigation algorithm in a loudspeaker amplification system that includes a loudspeaker driver, an audio amplifier, and a constant output power, power supply. A power requirement for the amplifier to output an audio signal is determined. A gain adjustment signal is then determined based on a difference between the power requirement and a power budget of the amplifier. Gain of the audio signal is adjusted according to the gain adjustment signal, for output through the loudspeaker driver. As a result, a peak level of the power consumption of the amplifier while outputting the gain-adjusted audio signal becomes less than the power budget. Other embodiments are also described and claimed.

Abstract: Methods, systems, and apparatuses for charging a host device from a charging source through an accessory are described. Upon detecting an input power signal from the charging source, an accessory may send an identification request to the host device and authenticate the host device based on the identification information received from the host device. Upon authenticating the host device, the accessory may enable a power path between the charging source and the host device to supply a charging current to charge the host device.

Abstract: A system and method for efficiently transferring data between devices. In various embodiments, a host computing device receives parallel data, encodes the parallel data as a count of pulses as serial data, and conveys the serial data to a peripheral device. The peripheral device decodes the received serial data to determine the parallel data, which is sent to processing logic. The devices send the encoded pluses on a bidirectional line, so the pulses are capable of being sent in both directions. The devices send the encoded pulses on the bidirectional line using a non-zero base voltage level. The devices are capable of using a voltage headroom when conveying encoded pulses between one another. Therefore, a full voltage swing between a ground reference voltage level and a power supply voltage level is not used when conveying the encoded pulses, which reduces power consumption.

Abstract: An electronic device may include a proximity sensor for detecting whether an external object is in the vicinity of the device. The proximity sensor may have a light detector and a light source that can be reused for data communications. The light detector may be coupled to optical receiver circuitry, whereas the light source may be coupled to optical transmitter circuitry. The optical transmitter circuitry may include encoding circuits configured to convert electrical signals to optical signals. The optical receiver circuitry may include decoding circuits configured to convert optical signals to electrical signals. The optical signals can be encoded and decoded using pulse width modulation schemes or amplitude modulation schemes.

Abstract: A method for operating a distributed wireless audio system including several loudspeaker cabinets all of which can communicate with each other as part of a computer network. The method receives temperature data that is indicative of temperature of a first loudspeaker cabinet, which has a network master responsibility of obtaining an audio signal from an audio source and wirelessly transmitting some of the audio signal to a second loudspeaker cabinet of several loudspeaker cabinets, for playback by the second loudspeaker cabinet, while playing back some of the audio signal by the first loudspeaker cabinet. The method determines whether a thermal threshold of the first loudspeaker cabinet has been reached, based on the temperature data. The method, in response to the thermal threshold being reached, gives up the network master responsibility from the first loudspeaker cabinet to the second loudspeaker cabinet, where doing so reduces temperature in the first loudspeaker cabinet.

Abstract: An operating power level for a loudspeaker cabinet and a target power level for the loudspeaker cabinet are determined during output of an audio signal by the loudspeaker cabinet. The target power level is based on temperature data for the loudspeaker cabinet and varies as the temperature data changes. Based on the operating power level and the target power level, values of two or more control parameters for controlling audio output of the loudspeaker cabinet are generated, where at least one of the control parameters controls the gain of a specific audio frequency band. The audio signal is adjusted according to the generated values of the control parameters, where doing so reduces power consumption of the loudspeaker cabinet during the audio output. Other embodiments are also described.

Abstract: A case can communicate with one or more earbuds to obtain information related to the earbuds, such as a battery charge level of the earbud. Due to the interface circuits within the case and the earbuds, the case can obtain the information from a power management unit of the earbud without first communicating with a processor (serving as the central processing unit) of the earbud. As a result, the processor can be powered down, i.e., inactive, and the case can still communicate with the earbud. Examples in which the processor can be powered down include when the earbud is in the case and not in use/service by a user, or when the earbud battery charge level is relatively low.
