System indicator board

Claim 2

System indicating apparatus comprising: a board having an array of substantially uniformly arranged slotted openings therein, a surfacing material covering said board and the unused ones of said slotted openings, said surfaces being breakable at said openings, electrical indicator devices with projections designed to project through said slotted openings Located on the viewing side of said board at selected locations corresponding to said slotted openings, with said projections extending through openings at said locations and through surface material broken thereat; such electrical devices being designed to represent the state of components or conditions of said system which are to be dynamically represented; means for cooperating with said projections for removably fastening said devices in place, means on said projections allowing the electrical coupling of electrical connections to said projections, on the rearward side of said board,

Claim 3

A system indicating apparatus as claimed in Claim 1 including: means portraying statically represented components of said system on the viewing side of said board in schematic functional relationship to the electrical devices.

Claim 4

Means for portraying the status of a system wherein the system includes elements whose change of state it is desired to observe and members whose change of state is assumed constant during the observation period, a board having an array of substantially uniformly arranged slotted openings therein; a surface covering said board and the unused ones of said slotted openings, said surface being breakable at said openings, whereby electrical indicator devices provided with projections designed to project through said slotted openings are located on the viewing side of said board at selected locations corresponding to said slotted openings, whereby means for cooperating with said projections are made for removably fastening said device at said selected locations, such devices and projections being designed so the electrical connections for said devices are made by connection to said projection rearwardly of said board, said electrical devices being designed and connectable to portray the state of conditions of said system which are dynamically portrayed, means on the same side of said board as said devices portraying visually the connections between the loci where said conditions exist portrayed by said devices.

Claim 5

Means for portraying the status of a system wherein the system includes elements whose change of state it is desired to observe and members whose change of state is assumed constant during the observation period, a board having an array of substantially uniformly arranged slotted openings therein; a surface covering said board and the unused ones of said slotted openings, said surface being breakable at said openings, whereby electrical indicator devices provided with projections designed to project through said slotted openings are located on the viewing side of said board at selected locations corresponding to said slotted openings, whereby means for cooperating with said projections are made for removably fastening said device at said selected locations, such devices and projections being designed so the electrical connections for said devices are made by connection to said projection rearwardly of said board, said electrical devices being designed and connectable to portray the state of conditions of said system which are dynamically portrayed, means on the same side of said board as said devices portraying visually the connections between the loci where said conditions exist portrayed by said devices.
