    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: A method and apparatus for mission critical standby of a portable communication device are disclosed. A portable communication device may include a primary processor for a first operating platform, a secondary processor for a second operating platform and communicatively coupled to the primary processor, and a power state manager that may have a first mode and a second mode. The power state manager may be configured to determine whether the primary processor is in a powered off state and sequence supply of power to the secondary processor. The first mode may allow the primary processor to monitor a power state of the secondary processor based on a determination that the primary processor is not in the powered off state and the second mode may enable the power state manager to monitor the power state based on a determination that the primary processor is in the powered off state.

    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: A communication system (100) formed of a portable radio (102) and radio accessory (106) is provided in which the accessory (106) provides emergency strobe and flashlight modes, the flashlight mode further providing a low battery indicator. Strategic control of lighting triggers and patterns allows for a single high intensity LED (132) to be used for both emergency strobe and flashlight modes, with minimized impact on battery life.

    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 camera flash system and method for the same. In one example, the system includes a camera including an image sensor, a plurality of lights, and an electronic processor. The camera is configured to capture an image frame. Each of the lights is configured to illuminate a region within the image frame. The electronic processor is configured to capture via the camera, while modulating an output of the plurality of lights, a first image frame and determine, using the image sensor, an object of interest within the first image frame. The electronic processor is further configured to identify a region of interest in which the object of interest is located based on the first image frame, identify, based on the region of interest, a subset of lights from the plurality of lights, and activate the subset of lights.
