ACOUSTICAL AND FIRE RESISTANT PARTICLEBOARD

摘要

An autonomous scanning circuit is realized by an arrangement of magnetically soft elements on the surface of a material in which single wall domains can be moved. Information representative of the conditions of a set of lines is stored in a domain register and compared with that of a previous scan period similarly stored. The expected one of two significant outputs from any given line is controlled by a unique domain circuit which remembers the next preceding output associated with that line.
