1. A system for determining the occurrence of abnormal motion of a surface, comprising:

  • a wireless motion detector for measuring three-dimensional acceleration motion data of the surface and wireless communications channel link energy data;

    a transmitter for transmitting the measured data;

    a receiver for receiving and storing the data from the wireless motion detector;

    a processor for processing the data to determine whether the surface has experienced abnormal motion by signal averaging, temporally smoothing the received data using dynamically sized moving average convolution filters, and comparing the processed data with stored data; and

    an output device for outputting an indication of the occurrence of abnormal motion of the surface based on the comparison.
