ABSTRACT:
An apparatus for interacting with articles passing through the apparatus. A spacially separate pair of switches are placed along the direction of movement of the articles and are disposed to detect the leading and trailing edges of the article. Output from the switches is received by a control system that produces an activating signal only when the pair of switches are in dissimilar states. The activating signal is received by means that interact with the article upon receipt of the activating signal.
