Abstract
The disclosure is directed to a method of detecting an object beneath a train. The method may include receiving a first signal indicative of a speed of the train, receiving a second signal indicative of a three generated by impact of the object with an impact element, and selecting a threshold value based on the speed of the train. The method may also include processing the second signal in accordance with a first procedure if the first signal indicates a speed of the train less than the threshold level, and processing the second signal in accordance with a second procedure different from the first procedure if the first signal is equal to or greater than the threshold level.
