Abstract: A portable electronic device including a battery coupled to an accessory circuit, a battery monitoring circuit coupled to the battery, and a processor connected to the battery monitoring circuit and the accessory circuit. The battery monitoring circuit determines an output current of the battery, and the processor receives an indication of the output current. The processor determines, based on the indication of the output current of the battery, a power characteristic of the accessory circuit, and control a power that is to be provided to the accessory circuit based on the power characteristic of the accessory circuit.

Abstract: Methods and devices for connecting an accessory device to a connector port of a mobile communication device and automatically detecting an operational mode of the connector port are provided. The method includes implementing a USB Type-C device detection at an electronic processor of the mobile communication device and monitoring a first and second pin of the connector port for pull-up and pull-down signals from a connected accessory. The method also includes interrupting the USB Type-C device detection when a pull-down signal is detected and determining whether an accessory signal is detected at a third pin of the connector port. The method also includes implementing a LMR accessory detection when the accessory signal is detected and completing the USB Type-C device detection when the accessory signal is not detected.

Abstract: Systems and methods for beamforming audio signals received from a microphone array. One example embodiment provides an electronic device. The electronic device includes a microphone array and an electronic processor communicatively coupled to the microphone array. The electronic processor is configured to estimate an ambient noise level. The electronic processor is configured to compare the ambient noise level to a first threshold and a second threshold, the second threshold being lower than the first threshold. The electronic processor is configured to determine a beam pattern for the microphone array based on the comparison of the ambient noise level to the first threshold and the second threshold. The electronic processor is configured to apply the beam pattern to an audio signal received by the microphone array.

Abstract: A grille configured for shielding a microphone cavity. The grille includes a first side. The first side includes a first plurality of parallel slats defining a first plurality of channels extending along a first direction. The grille includes a second side opposite the first side. The second side includes a second plurality of parallel slats defining a second plurality of channels extending along a second direction at a first angle relative to the first direction. The first plurality of parallel slats and the second plurality of parallel slats define a lattice having a plurality of openings extending through the grille. The openings are configured to diffuse air moving across the lattice. The channels and slats are configured to induce capillary action on water coming in contact with the lattice to drain water from the openings and the microphone cavity.

Abstract: Systems and methods for validating the operation of a transducer and an audio signal path to the transducer. An example method includes switching, with an audio switch, the audio signal path between an audio power amplifier and an analog-to-digital converter. The method includes routing an audio signal received from the transducer to the analog-to-digital converter when the audio power amplifier is not enabled. The method includes, upon receiving a button signal, processing, with an electronic processor, a digital version of the audio signal received from the analog-to-digital converter to generate a sample. The method includes comparing the sample to a reference audio sample. The method includes generating an alert when the sample does not match the reference audio sample.
