The disclosure relates to a detection device for detecting movement of a live insect located within a seed or grain. One jaw has two straight bars which project towards the other jaw and extend transversely of the sleeve to make two transverse indentations in the sleeve and the hose when the jaws are moving towards each other. The downstream surface of each plate is etched to provide gaps between plates for lateral fluid flow. Other systems and methods are also provided. The second flip-flop outputs third and fourth output signals. In this embodiment, the new information stored in the second memory can be verified to ensure that it is safe to load the new information into the first memory.
