Abstract
Abstract A system for composing alphanumeric characters and/or decorative designs from modules containing line segments. The line segments within each module are to be provided with means to make each line segment differentially visible, for example light-emitting diodes, liquid crystal displays, etc. The arrangement of line segments within the modules is the means whereby a variety of typefaces previously unobtainable in illuminated lettering or signage is now made available through the use of the present invention. Two module types, each with a different arrangement of line segments within, are herein specified.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
220 words
A system of modules for constructing alphanumeric characters and decorative and figurative designs by assembling such modules in a coplanar array, comprising: a group of modules, each being shaped so that said modules can be assembled in a coplanar array in an adjacent manner, each module having a major surface circumscribed by a plurality of straight edges, each module having a plurality of line segments thereon, said line segments having the following configuration: (a) a straight line transversing said major surface from a point between the ends of one edge to an opposite edge, (b) a straight line transversing said major surface from a point between the ends of one edge to an opposite edge and intersecting said line of clause (a) at approximately a right angle, (c) four straight lines, each of said straight lines connecting an end of said line of clause (a) to an end of said line of clause (b) by transversing said major surface at approximately a 45 degree angle to the edges thereof, (d) four curved lines, each of said curved lines connecting an end of said line of clause (a) to an end of said line of clause (b) by transversing said major surface in a manner so that each of said curved lines is convex to its adjacent line of clause (c).
Claim 2
Independent Claim
220 words
A system of modules for constructing alphanumeric characters and decorative and figurative designs by assembling such modules in a coplanar array, comprising: a group of modules, each being shaped so that said modules can be assembled in a coplanar array in an adjacent manner, each module having a major surface circumscribed by a plurality of straight edges, each module having a plurality of line segments thereon, said line segments having the following configuration: (a) a straight line transversing said major surface from a point between the ends of one edge to an opposite edge, (b) a straight line transversing said major surface from a point between the ends of one edge to an opposite edge and intersecting said line of clause (a) at approximately a right angle, (c) four straight lines, each of said straight lines connecting an end of said line of clause (a) to an end of said line of clause (b) by transversing said major surface at approximately a 45 degree angle to the edges thereof, (d) four curved lines, each of said curved lines connecting an end of said line of clause (a) to an end of said line of clause (b) by transversing said major surface in a manner so that each of said curved lines is convex to its adjacent line of clause (c).
Claim 3
Dependent Claim
26 words
The system of claim 1 wherein a plurality of said modules are assembled in a coplanar array so as to form a plurality of alphanumeric characters.
Claim 4
Dependent Claim
30 words
The system of claim 2 wherein said line segment patterns on said compound modules are constructed of a material that allows said line segment patterns to be made differentially visible.
Claim 5
Independent Claim
169 words
A system of modules for constructing alphanumeric characters and decorative and figurative designs by assembling such modules in a coplanar array, comprising: a group of modules, each being shaped so that said modules can be assembled in a coplanar array in an adjacent manner, each module having a major surface circumscribed by a plurality of straight edges, each module having a plurality of line segments thereon, said line segments having the following configuration: (a) a straight line tranversing said major surface from a point between the ends of one edge to an opposite edge, (b) a straight line transversing said major surface from a point between the ends of one edge to an opposite edge and intersecting said line of clause (a) at approximately a right angle, (c) four straight lines, each of said straight lines connecting an end of said line of clause (a) to an end of said line of clause (b) by transversing said major surface at approximately a 45 degree angle to the edges thereof,
Claim 6
Independent Claim
169 words
A system of modules for constructing alphanumeric characters and decorative and figurative designs by assembling such modules in a coplanar array, comprising: a group of modules, each being shaped so that said modules can be assembled in a coplanar array in an adjacent manner, each module having a major surface circumscribed by a plurality of straight edges, each module having a plurality of line segments thereon, said line segments having the following configuration: (a) a straight line tranversing said major surface from a point between the ends of one edge to an opposite edge, (b) a straight line transversing said major surface from a point between the ends of one edge to an opposite edge and intersecting said line of clause (a) at approximately a right angle, (c) four straight lines, each of said straight lines connecting an end of said line of clause (a) to an end of said line of clause (b) by transversing said major surface at approximately a 45 degree angle to the edges thereof,
Claim 7
Dependent Claim
