Abstract
Abstract An interchip for implantation into a gaming chip or token provides a circular array of light-receiving faces arrayed about the circumference of the chip or token. Light received by one face is conducted to the remainder of the faces by a number of internal fingers which communicate light to and from a central portion. The number of fingers and, hence, faces is selected to reflect the value and, hence, authenticity of the chip or token. Racks of such chips may be scanned or illuminated to detect their value or authenticity.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
73 words
An anticounterfeiting device for implantation within a chip or token comprising: a generally planar central light-conducting portion; and a plurality of light-conducting fingers extending from said central light-conducting portion in a generally planar relation to said central portion, each finger terminating in a respective light-receiving face, such that light received by a face of one of said fingers is transmitted through said central portion to the faces of each of the remaining fingers.
Claim 2
Dependent Claim
73 words
An anticounterfeiting device for implantation within a chip or token comprising: a generally planar central light-conducting portion; and a plurality of light-conducting fingers extending from said central light-conducting portion in a generally planar relation to said central portion, each finger terminating in a respective light-receiving face, such that light received by a face of one of said fingers is transmitted through said central portion to the faces of each of the remaining fingers.
Claim 3
Dependent Claim
78 words
Apparatus comprising: a generally flat token having a peripheral edge; an implant device embedded in said flat token; said implant device including a light-conducting central portion and a plurality of fingers each having a light-receiving end face and extending generally radially from said central portion so as to present a plurality of faces arrayed along said edge, said fingers further being formed of light-conducting material such that light applied to one of said faces illuminates the remainder thereof.
Claim 4
Dependent Claim
78 words
Apparatus comprising: a generally flat token having a peripheral edge; an implant device embedded in said flat token; said implant device including a light-conducting central portion and a plurality of fingers each having a light-receiving end face and extending generally radially from said central portion so as to present a plurality of faces arrayed along said edge, said fingers further being formed of light-conducting material such that light applied to one of said faces illuminates the remainder thereof.
Claim 5
Dependent Claim
17 words
The apparatus of claim 2, wherein said flat token is disc-shaped and wherein said periphery is circular.
Claim 6
Dependent Claim
24 words
The apparatus of claim 3, wherein said central portion is circular and said fingers comprise a plurality of spokes extending from said central portion.
Claim 7
Independent Claim
76 words
A system comprising: a plurality of gaming chips of generally circular configuration, each having a peripheral edge; means embedded in each of said gaming chips for presenting a plurality of light-receiving faces about said peripheral edge of said chip and for conducting light received at one of said faces to illuminate the remainder of said faces; rack means for retaining said chips in a stack; and light source means for illuminating a plurality of said chips.
Claim 8
Independent Claim
76 words
A system comprising: a plurality of gaming chips of generally circular configuration, each having a peripheral edge; means embedded in each of said gaming chips for presenting a plurality of light-receiving faces about said peripheral edge of said chip and for conducting light received at one of said faces to illuminate the remainder of said faces; rack means for retaining said chips in a stack; and light source means for illuminating a plurality of said chips.
Claim 9
Dependent Claim
11 words
The system of claim 5, wherein said peripheral edge is circular.
Claim 10
Dependent Claim
20 words
The system of claim 6, wherein said means presenting a plurality of light-receiving faces comprises a plurality of light-conducting fingers.
Claim 11
Dependent Claim
52 words
Apparatus comprising: a gaming chip having top and bottom surfaces and a peripheral edge; and means embedded in said gaming chip for presenting a plurality of light-receiving faces about said peripheral edge of said chip and for conducting light received at one of said faces to illuminate the remainder of said faces.
Claim 12
Dependent Claim
52 words
Apparatus comprising: a gaming chip having top and bottom surfaces and a peripheral edge; and means embedded in said gaming chip for presenting a plurality of light-receiving faces about said peripheral edge of said chip and for conducting light received at one of said faces to illuminate the remainder of said faces.
Claim 13
Dependent Claim
124 words
Apparatus comprising: a generally flat disc-shaped token having a center and a circular peripheral edge disposed at a selected radius from said center; an implant device embedded in said flat token; said implant device including a light-conducting, disc-shaped central portion of a radius less than the radius of said token, said central portion being located concentrically with said token; and a plurality of fingers extending generally radially from said central portion so as to present a plurality of faces of rectangular cross-section spaced at equal intervals along said edge, said fingers further being formed of light-conducting material such that light applied to one of said faces illuminates the remainder thereof, said fingers and light-conducting central portion further lying in coplanar relationship with one another.
Claim 14
Dependent Claim
124 words
Apparatus comprising: a generally flat disc-shaped token having a center and a circular peripheral edge disposed at a selected radius from said center; an implant device embedded in said flat token; said implant device including a light-conducting, disc-shaped central portion of a radius less than the radius of said token, said central portion being located concentrically with said token; and a plurality of fingers extending generally radially from said central portion so as to present a plurality of faces of rectangular cross-section spaced at equal intervals along said edge, said fingers further being formed of light-conducting material such that light applied to one of said faces illuminates the remainder thereof, said fingers and light-conducting central portion further lying in coplanar relationship with one another.
Claim 15
Dependent Claim
32 words
The apparatus of claim 9, wherein said edge is translucent and said faces each lie beneath said edge such that they are concealed from view unless said edge is exposed to illumination.
Claim 16
Dependent Claim
25 words
The apparatus of claim 9 wherein said implant device is constructed of a material which causes it to take on the color of said token.
