INDICATION BOARD Russian patent published in 1997 - IPC

FIELD: automation and computer engineering, in particular, information displaying elements for different information systems, boards and so on. SUBSTANCE: device has indicators which have permanent magnets, electric magnets which are mounted on opposite side of front panel for engagement with permanent magnets. Each electric magnet and corresponding indicator provide n different information channels. Indication board has magnetic circuit layer and two dielectric layers. Electric magnets are flat and are located between dielectric layers. Free surface of one dielectric layer is joined with opposite side of front panel. Another dielectric layer is joined to magnetic circuit layer. Indicators are flat and are mounted for movement with respect to front panel. Front panel and all layers are connected to each other. EFFECT: simplified design, decreased weight and size, simplified manufacturing, increased reliability, decreased cost. 3 dwg
