Abstract: Methods, apparatus, systems and articles of manufacture for acoustic system noise mitigation are disclosed. An example apparatus includes a sound sensor and one or more electronic components. The apparatus also includes a background noise analyzer to obtain sensor data indicative of background noise in an environment of the apparatus from the sound sensor. The apparatus also includes a system noise analyzer to select a first system noise profile indicative of acoustic noise associated with operating the one or more electronic components according to a first system configuration. The apparatus also includes a system noise controller to operate the one or more electronic components according to the first system configuration of the first system noise profile.

Abstract: In some examples, a voltage protection apparatus includes a circuit to compare an input voltage of a processor to a threshold voltage, and to provide a throttle signal to the processor if the input voltage of the processor droops below the threshold voltage. The processor input voltage can then be set to a lower voltage and the processor power can thus be lowered.

Abstract: Some embodiments include apparatuses and methods having a node to couple to a serial bus, and a controller to provide a control signal to one of a first circuit path and a second circuit path in order to change electrical termination of a signal at the node between a first electrical termination through the first circuit path during a first mode of the controller and a second electrical termination through the second circuit path during a second mode of the controller. The controller can be arranged to provide the control signal to the first and second circuit paths during the first and second modes without providing another control signal from the controller to the first and second circuit paths during the first and second modes.

Abstract: A voltage converter for converting an input voltage to a different output voltage includes an output filter for providing the output voltage and a voltage switch coupled in series between the input voltage and the output filter. A controller compares the output voltage to a reference voltage and in response thereto, provides signals to turn the voltage switch on or off. A level shifter is coupled between the controller and the voltage switch.
