    Abstract: Systems and methods are described herein to accommodate different settings associated with an inverter-based electric power generator for electric power generation within an electric power delivery system. The electric power delivery system may provide electric power generated by a bulk electric system to the loads via distributed substations using a first operating frequency. Moreover, the distributed substations may include inverter-based electric power generators to supply the electric power demand of downstream loads in an islanded configuration. That said, the inverter-based electric power generators may supply the electric power using a second frequency that is higher than the first frequency. Protective systems, positioned downstream from the distributed substations, may use different settings associated with the bulk electric system or the inverter-based electric power generators based on detecting the frequency of the supplied electric power.

    Abstract: A computer-readable medium may include instructions that may cause a processor to perform operations that may include receiving audio data representative of sound waves generated by industrial devices and extracting features from the audio data. The features may be representative of a portion of the audio data. The operations may also include identifying a subset of the features based on distances between each of the plurality of features in an information space. The information space may include known clusters. The operations may then include determining that the subset of the features corresponds to an unknown cluster in the information space, performing a constrained classification operation based on each feature of the subset of the features to identify a new known cluster for the information space, and modifying operations of the industrial devices based on the new known cluster.

    Abstract: A blower mounting assembly of a heating, ventilation, and/or air conditioning (HVAC) system includes a bracket assembly including a base panel, a plurality of mounting flanges extending from the base panel, and an alignment flange extending from and transverse to the base panel. The blower mounting assembly includes a first mounting aperture extending through the base panel in a first direction and includes second mounting apertures extending through the plurality of mounting flanges in a second direction transverse to the first direction. The blower mounting assembly includes a bolt configured to extend through and slidably engage with an aperture of the alignment flange and a blower mounting skid such that the bolt limits movement of the blower mounting skid relative to the bracket assembly. The aperture of the alignment flange extends through the alignment flange in a third direction transverse to the first mounting aperture and the second mounting apertures.

    Abstract: A smart speaker power controller may be configured to receive power conforming to one of a plurality of power modes from an input power source. The power controller may be further configured to communicate the power mode to at least one component of a processing system or at least one component of an audio system for operating the smart speaker according to the received power mode, including determining a current limit of a power converter; determining a shutdown voltage threshold and safely shutting down the smart speaker if the input voltage falls below the threshold, and/or modifying audio operation of the smart speaker in response to the power mode. The smart speaker can further include an audio power supply controller configured to monitor energy required to reproduce an audio signal and to servo a power supply voltage provided to an audio amplifier in response to this energy level.
