One of the Canadian company's developments was the flip-disc display, which creates a large display out of a grid of small disks, painted black on one side and some bright color (typically yellow) on the other. A small magnet glued to the disk responded to a magnetic pulse from a coil which surrounded the disk. The direction of current through the coil determined the side to display. A display system was sold to the Montreal and Canadian stock exchanges in 1964. The UK headquarters gave the invention little note, but it became somewhat successful in spite of this, and HQ eventually used it as a way to try to sell off the Canadian division in the 1970s. In addition Air Canada commenced use at all its baggage claims, but also used for Flight information displays, starting with its new terminal at the Kennedy Terminal in New York. Today, these displays can commonly be found in outdoor use, notably on highway signage and in the automotive application of destination signs for public service vehicles.
