  • Acceleration-based window glass break detection
    Patent number: 10346132
    Abstract: A telematics device located on-board a vehicle or other enclosure assists in detecting a glass break event for a window of the vehicle or enclosure based on acceleration measurements obtained from acceleration sensors of the telematics device. A power spectral density (PSD) for a plurality of packets of acceleration data within a higher frequency band and/or a lower frequency band are determined. A glass break event is detected upon determining that an average PSD for the higher frequency band exceeds an upper PSD threshold. Alternatively or additionally, a glass break event is detected upon determining that a second maximum PSD is greater than a first PSD threshold for the lower frequency band, and that a difference between the second maximum PSD and a minimum PSD is greater than a second PSD threshold for the lower frequency band.
