US 10,300,876 B1 · Detection and classification of events

Abstract

Systems and approaches for detecting an event, such as a crash involving a motorized and/or non-motorized vehicle, are described. In one approach, a listening component of a mobile computing device is first activated. This listening component may then monitor the sound proximate thereto (e.g., within the vehicle in which the mobile computing device is disposed). Using one or more processors, an audio source may be detected which was generated by an event (such as, for example, a crash involving the vehicle and/or an alerting triggering phrase) and was sensed by the listening component. Using an audio recognition technique, the detected audio source is processed to determine a severity of the event which generated the audio signal. This detection step may include identifying a type and magnitude of the detected audio signal using audio signal identification data. An information signal based on the severity of the event is then transmitted.

Dependent claims

A method of detecting a crash involving a vehicle, the method comprising:

activating a listening component of a mobile computing device, the listening component including a microphone;
monitoring, at the listening component, sound proximate the vehicle;
detecting, by one or more processors, an audio signal that was generated by a crash involving the vehicle and sensed by the microphone of the listening component of the mobile computing device while monitoring sound proximate the vehicle;
processing, by one or more processors and using an audio recognition technique, the detected audio signal to identify the crash and to determine a severity of the crash that was the source of the audio signal, wherein processing the detected audio signal to determine the severity of the crash that was the source of the audio signal includes identifying a type and magnitude of the detected audio signal using audio signal identification data;
and
transmitting, by one or more processors, an event information signal based on the determined severity of the crash;
wherein detecting the audio signal comprises detecting an alerting verbal phrase, and wherein a decibel level of the alerting verbal phrase is used to determine the severity of the crash.

4 more elements

A non-transitory computer-readable storage medium comprising computer-readable instructions to be executed on one or more processors of a system for detecting a crash involving a vehicle, the instructions when executed causing the one or more processors to:

activate a listening component of a mobile computing device, the listening component including a microphone;
monitor sound proximate the vehicle;
detect an audio signal that was generated by a crash involving the vehicle and sensed by the microphone of the listening component of the mobile computing device while monitoring sound proximate the vehicle, wherein the audio signal is representative of an alert triggering phrase in the form of an alerting verbal phrase;
process the detected audio signal using an audio recognition technique to identify the crash and to determine a severity of the crash that was the source of the audio signal, wherein a decibel level of the alerting verbal phrase is used to determine the severity of the crash;
and cause an event information signal based on the determined severity of the crash to be transmitted.
