Abstract
Abstract An adaptor bracket for the mounting of a color sensor head and a support pad held in a specific orientation such that the light emitted from the color sensor head strikes the support pad in a manner that the reflected light is directed back towards the color sensor head while the support pad serves as a low friction surface over which a flexible translucent material can be passed for measurement of its color quality.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
169 words
A color sensor assembly for mounting a color sensor head and for supporting a translating flexible translucent material whose color is to be measured comprising: a color sensor head having a light emitting means for generating an emitted light and a receiving means for detecting a reflected light; a support pad having a first side contacting and supporting said translating flexible translucent material, said first side having a relatively low coefficient of friction when said translating flexible translucent material passes thereover and having a high value of reflectivity to said emitted light, said support pad having a second side for mounting; an adaptor bracket having a first flange connected to a second flange where said support pad second side is mounted to said first flange and where said color sensor head is mounted to said second flange such that said emitted light is directed toward said support pad reflecting therefrom to said receiving means with said translating flexible translucent material interposed between said emitted light and said support pad.
Claim 2
Dependent Claim
169 words
A color sensor assembly for mounting a color sensor head and for supporting a translating flexible translucent material whose color is to be measured comprising: a color sensor head having a light emitting means for generating an emitted light and a receiving means for detecting a reflected light; a support pad having a first side contacting and supporting said translating flexible translucent material, said first side having a relatively low coefficient of friction when said translating flexible translucent material passes thereover and having a high value of reflectivity to said emitted light, said support pad having a second side for mounting; an adaptor bracket having a first flange connected to a second flange where said support pad second side is mounted to said first flange and where said color sensor head is mounted to said second flange such that said emitted light is directed toward said support pad reflecting therefrom to said receiving means with said translating flexible translucent material interposed between said emitted light and said support pad.
Claim 3
Dependent Claim
21 words
The color sensor assembly of claim 1, wherein said adaptor bracket first flange opposes and is parallel to said second flange.
Claim 4
Dependent Claim
17 words
The color sensor assembly of claim 1, wherein said support pad is made of a polytetrafluoroethylene material.
Claim 5
Dependent Claim
15 words
The color sensor assembly of claim 1, wherein said support pad is white in color.
Claim 6
Dependent Claim

Claim 10
Independent Claim
225 words
A method of detecting the color of a translating translucent flexible material comprising: providing a color sensing means having a light emitting means for generating and directing an emitted light and a receiving means for detecting a reflected light and a processing means for generating a signal indicative of color based on said reflected light; providing a support pad having a first side contacting and supporting said translating translucent flexible material, said first side having a low coefficient of friction when said translating flexible material passes thereover, said support pad having a high value of reflectivity to said emitted light and said support pad having a second side for mounting; providing an adaptor bracket having a first flange for mounting said light emitting means and said light receiving means, said adaptor bracket having a second flange for mounting said support pad oriented such that said translating translucent flexible material is interposed between said light emitting means, said receiving means and said support pad; emitting a light from said light emitting means to pass through said translating translucent flexible material and to impinge upon said support pad; reflecting said light back through said translating translucent flexible material; receiving said reflected light with said receiving means; processing an output of said receiving means to generate a signal indicative of the color of said translating translucent flexible material.
Claim 11
Independent Claim
225 words
A method of detecting the color of a translating translucent flexible material comprising: providing a color sensing means having a light emitting means for generating and directing an emitted light and a receiving means for detecting a reflected light and a processing means for generating a signal indicative of color based on said reflected light; providing a support pad having a first side contacting and supporting said translating translucent flexible material, said first side having a low coefficient of friction when said translating flexible material passes thereover, said support pad having a high value of reflectivity to said emitted light and said support pad having a second side for mounting; providing an adaptor bracket having a first flange for mounting said light emitting means and said light receiving means, said adaptor bracket having a second flange for mounting said support pad oriented such that said translating translucent flexible material is interposed between said light emitting means, said receiving means and said support pad; emitting a light from said light emitting means to pass through said translating translucent flexible material and to impinge upon said support pad; reflecting said light back through said translating translucent flexible material; receiving said reflected light with said receiving means; processing an output of said receiving means to generate a signal indicative of the color of said translating translucent flexible material.
Claim 12
Dependent Claim
33 words
The method of detecting the color of the translating translucent flexible material of claim 9, wherein said light emitting means consists of at least one LED projecting light into an optical fiber cable.
Claim 13
Dependent Claim
35 words
The method of detecting the color of a translating translucent flexible material of claim 9, wherein said receiving means consists of an optical fiber cable to direct said reflected light to a light sensitive diode.
Claim 14
Dependent Claim
28 words
The method of detecting the color of a translating translucent flexible material of claim 9, further comprising: passing said material over said support pad in a continuous manner.
