Abstract
An alert device for a moving device having a variable acceleration includes a sensing unit and a processor. The sensing unit senses the variable acceleration to generate a plurality of acceleration data. The processor determines a first plurality of acceleration data samples and a second plurality of acceleration data samples from the plurality of acceleration data based on two different predetermined sample sizes and a moving average algorithm to correspondingly calculate a first plurality of sample averages and a second plurality of sample averages, obtains a plurality of sample average differences between the first and the second pluralities of sample averages, analyzes the plurality of sample average differences based on a predetermined check algorithm to obtain a derived resultant value, and performs a data comparison between the derived resultant value and a predetermined threshold value to generate a comparison result.
