A magnetic film stack is composed of a synthetic antiferromagnet including a plurality of ferromagnetic layers, adjacent two of which are antiferromagnetically coupled through a non-magnetic layer; and a reversal inducing layer exhibiting ferromagnetism. The inventor device comprises a set of conductive patterns which are distributed over the two contact surfaces and which are separated by insulating zones. The determination unit determines whether or not the telegram which is received by the reception unit includes a command related to a communication path. For each pixel location on each cylindrical surface, a fitness metric is computed for all the pixels projected thereon to provide an indication of how closely a prescribed characteristic of the projected pixels matches. The first belt conductively connected to the drawer and to a first fixed point which forms a conductive path from the drawer to the first fixed point. Upon receipt of search query from a user, the search engine submits a request to the queue manager.
