Abstract
The invention includes a device and a method for recognizing the instantaneous position of a plurality of mechanical parts, the parts being linearly and incrementally movable between a departure position and an arrival position. The device includes a plurality of radiation modifying tags respectively associated and movable with the mechanical parts. There are a plurality of pairs of radiation emitters and receivers located on the opposite sides of the parts at incremental positions, whereby the pressence of a tag between a given pair causes modification of the radiation received by an associated receiver. The device further provides for generating detect signals from the receivers, and for recognizing that corroborating detect signals from the receivers correspond to a specific set of positions of the mechanical parts.
