Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A method of making an optical scanning element, comprising: winding at least one optical fiber onto a cylindrical drum such that a plurality of coils of said optical fiber are formed on the drum; adhering the coils of said fiber together; removing the coils of said fiber from said drum and making at least one cut in the coils of said fiber; positioning the coils of said fiber between V-shaped male and female dies to form them into a V shape; molding a polymeric support around the coils of said fiber; and removing a portion of said polymeric support so as to cut the bottoms of said V-shaped coils of said fiber to separate those coils of said fiber into plural transmitting and receiving fibers.
Claim 2
Independent Claim
125 words
A method of making an optical scanning element, comprising: winding at least one optical fiber onto a cylindrical drum such that a plurality of coils of said optical fiber are formed on the drum; adhering the coils of said fiber together; removing the coils of said fiber from said drum and making at least one cut in the coils of said fiber; positioning the coils of said fiber between V-shaped male and female dies to form them into a V shape; molding a polymeric support around the coils of said fiber; and removing a portion of said polymeric support so as to cut the bottoms of said V-shaped coils of said fiber to separate those coils of said fiber into plural transmitting and receiving fibers.
Claim 3
Dependent Claim
47 words
The method of claim 1 that further includes adhering the coils of said fiber together by adhering a polymeric strip to the coils of said fiber, and positioning said polymeric strip along the bottom of said female die to retain the V shape imparted by said dies.
Claim 4
Dependent Claim
23 words
The method of claim 2 wherein at least one diagonal cut is made to release the coils of said fiber from said drum.
Claim 5
Dependent Claim
13 words
The method of claim 3 where at least two diagonal cuts are made.
Claim 6
Dependent Claim
20 words
The method of claim 1 wherein a translucent layer is applied to the ends of said transmitting and receiving fibers.
Claim 7
Dependent Claim
13 words
The method of claim 5 wherein said translucent layer comprises a glass slide.
