A method for automatically determining a fault of a vehicle comprises receiving one or more audio signals from one or more microphones of the vehicle; extracting diagnostic metadata from the received one or more audio signals; extracting a diagnostic feature from the diagnostic metadata, the extracted diagnostic feature corresponding to a feature of a trained machine-learning based model for determining a fault based on a learned association between the extracted diagnostic feature and a fault of the vehicle; and automatically determining the fault based on the extracted diagnostic feature, by using the trained machine-learning based model that was trained based on a first feature extracted from first training metadata regarding previously recorded data and a second feature extracted from metadata regarding a previous fault related to the previously recorded data, based on the learned association between the extracted diagnostic feature and the fault.

Real-time gunshot detection and reporting. A computing device detects, in an audio signal received by an audio receiver that includes a plurality of audio receiving elements, at least one gunshot. The computing device determines, based on the plurality of audio receiving elements, an audio location of the at least one gunshot. The computing device sends control signals to at least two cameras to cause the at least two cameras to capture at least two corresponding images of the audio location. The computing device, based on the at least two corresponding images, identifies a gunshot location and transmits a gunshot location identifier that identifies the gunshot location to a destination.

A system and a method, as well as a positioning and wearable devices for determining the distance and position of devices communicating with each other over a medium, the system, are disclosed. At least one remote device comprises first processing unit, at least one transmitter functionally connected to the first processing unit and adapted to transmit signals over a medium, and at least one receiver functionally connected to the first processing unit and adapted to receive signals over said medium. At least two wearable devices, each comprising a second processing unit and wireless communication means capable of receiving and sending data signals over said medium, are also provided. The remote device is adapted to determine the distance to at least two wearable devices, to determine the direction to said at least two wearable devices based on at least two different bearings taken from said at least one remote device to each wearable device, to calculate the position of said at least two wearable devices relative to the remote device, and to communicate the position of at least one first wearable device to a second wearable device. The wearable devices are adapted to process the position of a first wearable device in their processing unit and to present to the user of a second wearable device an indication of direction and distance to said first wearable device.
