Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
A READOUT DEVICE COMPRISING: A PLURALITY OF GROUPS OF OPTIC FIBERS, EACH FIBER HAVING FIRST AND SECOND ENDS REMOTE FROM EACH OTHER; SAID FIRST ENDS OF EACH GROUP OF SAID FIBERS TERMINATING AT A RESPECTIVE PORTION OF A LIGHT RECEIVING SURFACE; SAID SECOND ENDS OF SAID FIBERS TERMINATING AT A COMMON DISPLAY SURFACE, THE SECOND ENDS OF SAID FIBERS OF EACH OF SAID GROUPS DEFINING A VISUAL CHARACTER AREA AT SAID DISPLAY SURFACE AND THE SECOND ENDS OF A GROUP OF FIBERS DEFINING ONE VISUAL CHARACTER AREA INTERSPERSED WITH THE SECOND ENDS OF ANOTHER GROUP OF FIBERS DEFINING A DIFFERENT VISUAL CHARACTER AREA WHEREBY THE VISUAL CHARACTER AREAS DEFINED BY DIFFERENT ONES OF SAID GROUPS OF FIBERS OVERLAP; AND A PLURALITY OF LIGHT SOURCES EACH ILLUMINATING, WHEN ENERGIZED, A RESPECTIVE PORTION OF SAID LIGHT RECEIVING SURFACE.
Claim 2
Dependent Claim

Claim 3
Independent Claim
131 words
A METHOD FOR PRODUCING A FIBER OPTIC READOUT DEVICE AND WHICH COMPRISES: ESTABLISHING A PLURALITY OF SEPARATOR MEANS FOR DEFINING A PLURALITY OF SEPARATE LIGHT RECEIVING AREAS; REPEATEDLY LAYING A CONTINUOUS OPTIC FIBER STRAND SO THAT FIBER PORTIONS THEREOF LIE IN ROWS OF FIBER PORTIONS WHICH EXTEND THROUGH A DISPLAY SURFACE PLANE SPACED FROM SAID LIGHT RECEIVING AREAS, EACH FIBER PORTION OF SAID ROWS BEING GENERALLY LAID ADJACENT THE NEXT PRECEDING LAID FIBER PORTION; EXTENDING SAID FIBER STRAND SELECTIVELY BETWEEN SAID SEPARATOR MEANS BETWEEN THE LAYING OF EACH OF SAID FIBER PORTIONS AT SAID DISPLAY SURFACE; SEVERING SAID FIBER PORTIONS ACROSS A SURFACE WHICH PASSES THROUGH SAID LIGHT RECEIVING AREAS; SEVERING SAID FIBER PORTIONS ALONG SAID DISPLAY SURFACE PLANE; AND ESTABLISHING LIGHT SOURCES IN ILLUMINATING RELATIONSHIP WITH SAID LIGHT RECEIVING AREAS.
