In 2001, Alan Brownlie began work with a unique force sensor array (FSA) pressure pad.  The pad is like a blanket equipped with numerous sensor points throughout it’s interior that interfaces with a computer.  

Alan used the pad on the backs of horses, underneath the saddle, to measure pressure points caused by a poor fit.  The results were uploaded to the FSA program on a computer, either in real-time, or after being recorded remotely.  The remote capability of the pressure pad allowed Alan to view results of a rider atop a moving horse and see how the pressure points varied while the horse galloped and even jumped.  Using the results of the FSA pad, he could compare a standard saddle pad to a variety of prototypes of aircell pads he was developing.

The visual results were astonishing.  

On a computer, the FSA pad shows the changes in pressure from one point to surrounding areas.  A good reading would be an even distribution of pressure throughout the saddle resulting in a uniform color.  A poor reading would show bright red or orange pressure points.  With the air cell pads underneath the saddle, the weight of the rider was evenly distributed throughout horse’s back.
