The whole thing is very amateurish.
Firstly, you'd need a whole paper on tests carried out to establish the accuracy of the equipment using known variables.
Secondly, was their methodology valid? We'd need a second paper to prove that the reactions they found can be compared to real life situations, and thirdly, there was no mention of a control group.
And that's just off the top of my head. I'm sure someone currently involved in this sort of research would tear this to pieces.
