Abstract
Sensor modules () including accelerometers () are placed on a physical structure () and tri-axial accelerometer data is converted to mechanical power (P) data () which then processed to provide a forewarning () of a critical event concerning the physical structure (). The forewarning is based on a number of occurrences of a composite measure of dissimilarity (C) exceeding a forewarning threshold over a defined sampling time; and a forewarning signal () is provided to a human observer through a visual, audible or tangible signal. A forewarning of a structural failure can also be provided based on a number of occurrences of (C) above a failure value threshold.
