Abstract: A method may include receiving information indicative of an amplitude of an audio output signal, receiving information indicative of a predicted voltage of a power supply of a signal path having an audio input for receiving an audio input signal and an audio output for generating the audio output signal based on the audio input signal, predicting from the information indicative of the amplitude of the audio output signal and the information indicative of the predicted voltage of the power supply whether the audio output signal will exceed an available supply voltage generated by the power supply, and responsive to determining the audio output signal will exceed the available supply voltage generated by the power supply, attenuating the audio input signal or a derivative thereof to reduce the amplitude of the audio output signal such that the audio output signal does not exceed the available supply voltage of the power supply.

Abstract: A predictive brownout prevention system may be configured to prevent brownout of an audio output signal. Particularly, the brownout prevention system may be configured to receive information indicative of adaptive estimates of power supply conditions, wherein the information indicative of adaptive estimates of the power supply conditions comprises information regarding a voltage component and a resistive component received from an adaptive battery model of a battery for providing electrical energy to a power supply for generating the power supply voltage and adapt the adaptive battery model based on a monitored battery voltage output by the battery and loading events of the signal path and excluding loading events of components other than the signal path which are powered from the battery.

Abstract: A distributed network system may include a shared communication bus that operates in accordance with a communication protocol and a plurality of devices coupled to the bus. In accordance with the communication protocol, when one or more of the plurality of devices is actively transmitting data on the bus, each of the plurality of devices receives data via the bus such that bidirectional communication is established among the plurality of devices via the bus, each of the plurality of devices monitors a bus state of the shared communication bus to avoid data contention and to synchronize receipt of encoded symbols and encoded messages comprising encoded symbols via the bus, and each actively transmitting device of the plurality of devices compares the bus state to a desired state of such actively transmitting device to determine a priority among actively transmitting devices of the plurality of devices with respect to the bus.
