Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
For an electro-optical signal translator that serves as an interface between electrical and optical signals, a method of illuminating mating inner surfaces of at least one translator component and a translator component mounting substrate, comprising the steps of: directing radiation through the thickness of a selected one of a first group that comprises said substrate and said at least one component that has a spectrum that at least overlaps the transparent region of the absorption spectrum for the thickness of said selected one of said group; and monitoring said radiation that is reflected off of at least a portion of said upper surface of said substrate and at least a portion of said adjacent lower surface of said at least one component.
Claim 2
Dependent Claim
122 words
For an electro-optical signal translator that serves as an interface between electrical and optical signals, a method of illuminating mating inner surfaces of at least one translator component and a translator component mounting substrate, comprising the steps of: directing radiation through the thickness of a selected one of a first group that comprises said substrate and said at least one component that has a spectrum that at least overlaps the transparent region of the absorption spectrum for the thickness of said selected one of said group; and monitoring said radiation that is reflected off of at least a portion of said upper surface of said substrate and at least a portion of said adjacent lower surface of said at least one component.
Claim 3
Dependent Claim
54 words
The method as set forth in claim 1, wherein said step of directing said radiation that has a spectrum that at least overlaps the transparent region of the absorption spectrum for the thickness of said selected one of said group further comprises the step of selecting said at least one component from said group.
Claim 4
Dependent Claim
55 words
The method as set forth in claim 2, wherein said step of directing radiation that has a spectrum that at least overlaps the transparent region of the absorption spectrum for the thickness of said at least one component comprises directing said radiation toward said substrate from an upper surface of said at least one component.
Claim 5
Dependent Claim
31 words
The method as set forth in claim 3, wherein said step of monitoring said reflected radiation comprises monitoring said reflected radiation from said upper surface of said at least one component.
Claim 6
Dependent Claim
44 words
The method as set forth in claim 2, wherein said step of directing said radiation that has a spectrum that at least overlaps the transparent region of the absorption spectrum for the thickness of said at least one component comprises directing noncoherent infrared radiation.
Claim 7
Dependent Claim
43 words
The method as set forth in claim 2, wherein said step of directing said radiation that has a spectrum that at least overlaps the transparent region of the absorption spectrum for the thickness of said at least one component comprises directing laser radiation.
