to contrast the markings 12, 14 with the substrate 10, envelope
18, and protective enclosure 20. The detected image is then sent
in electronic form or printed [see Fig. 1 and specification,
¶ 0016].
Gilpatrick relates to marking objects that are later
inspected using x-ray techniques, such as textile substrates,
yarns, or other objects, to locate defects or identify components
that are otherwise difficult or impossible to detect visually
[Gilpatrick, col. 1, lines 4-12]. Gilpatrick notes that
manufactured fabric or yarn is typically wound on rolls and
marked during the inspection process. The marks on all but the
outermost portion of the rolls are hidden from view [Gilpatrick,
col. 3, lines 11-26]. Detection of these otherwise undetectable
marks is made possible by directing x-rays through the object
using a conventional x-ray device and examining the resulting
x-ray images on a video display [id; col. 3, line 55 - col. 4,
line 5].
We conclude that Gilpatrick is in the same field of endeavor
as the invention. Both the claimed invention and Gilpatrick
