1. A mobile computing device comprising:

  • an accelerometer configured to measure acceleration of at least one axis of the accelerometer;

    communication circuitry configured to wirelessly communicate with other devices;

    a processor; and

    memory storing computer-executable instructions that, when executed by the processor, cause the processor of the mobile computing device to;

    receive acceleration measurements measured by the accelerometer;

    determine, based on the acceleration measurements measured by the accelerometer, a number of a plurality of acceleration events during a predetermined time window;

    determine whether the number of the plurality of acceleration events during the predetermined time window exceeds a threshold number of acceleration events;

    determine whether each of the plurality of acceleration events exceeding the threshold number of acceleration events has a magnitude exceeding an acceleration magnitude threshold;

    when the number of the plurality of acceleration events during the predetermined time window exceeds the threshold number of acceleration events and each of the plurality of acceleration events exceeding the threshold number of acceleration events has a magnitude exceeding the acceleration magnitude threshold, determine that the mobile computing device is within a vehicle and that the vehicle was involved in a crash; and

    responsive to determining that the vehicle was involved in the crash, send, via the communication circuitry and to a crash detection server, information identifying the mobile computing device and information corresponding to the crash.
