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 shared communication bus. The communication protocol may define periods of time and an order by which each of the plurality of devices actively transmit data on the shared communication bus such that only one of the plurality of devices actively transmits data on the shared communication bus at a time to a remaining number of the plurality of devices through the shared communication bus. When the remaining number of the plurality of devices are not actively transmitting data, the remaining number of the plurality of devices may receive data via the shared communication bus so that bi-directional communication is established among the plurality of devices on the shared communication bus.

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 an amplitude of the audio input signal, receive information indicative of a condition of the power supply, determine from the information indicative of an amplitude of the audio input signal and the information indicative of the condition of the power supply whether a brownout condition exists, and responsive to determining the brownout condition exists, generate the selectable attenuation signal to reduce an amplitude of the audio output signal such that the signal path attenuates the audio input signal or a derivative thereof in order to prevent brownout prior to propagation to the audio output of a portion of the audio input signal having the brownout condition.

Abstract: In accordance with embodiments of the present disclosure a control circuit may include at least one input for monitoring a respective signal for each of a plurality of amplifiers, an output for outputting at least one control signal for controlling a power supply level of the single signal-variant power supply configured to deliver electrical energy to the plurality of amplifiers, and decision and control logic. The decision and control logic may be configured to monitor the respective signals for each of the plurality of amplifiers and, based on the respective signals, and a respective requirement associated with each of the plurality of amplifiers, setting a power supply level of the single signal-variant power supply and outputting the at least one control signal to control the power supply level such that the respective requirements are satisfied.

Abstract: Audio amplification may be improved by controlling an audio amplifier based on the audio signal being amplified. For example, when the audio signal level increases or decreases, a boost voltage provided to an audio amplifier by a boost converter may also be increased or decreased. In another example, when the audio signal level decrease below a certain level, the audio amplifier may be switched from amplifying the audio signal with a boost converter input to amplifying the audio signal with a low voltage input. Control of the audio amplifier may be implemented in a digital boost converter controller coupled to the boost converter and/or the audio amplifier.
