Application No. 09/270,688
places his/her foot directly thereon. In operation, the customer
places his/her foot in channel 26 such that the bottom of the
foot is scanned by the laser unit which traverses safety glass
114. The system is independent of actual foot position due to
the operation of the scanners. The scanners will accurately scan
the distances of the bottom surface of the foot regardless if the
foot position is askew on the glass. See page 10 of Appellants'
specification.
Independent claim 1 is representative of Appellants' claimed
invention and is reproduced as follows:
1. A method of forming a custom-made insole comprising the
steps of:
randomly positioning a foot to be measured on a laser
scanning station;
passing at least one laser scanning unit along an
undersurface of the foot;
scanning the undersurface of the foot with the at least one
laser scanning unit by directing at least one line of laser light
along the undersurface;
measuring surface coordinates of the undersurface detected
by the at least one laser scanning unit;
processing the measured surface coordinates;
transmitting the processed measured surface coordinates to a
data processing unit; and
milling a custom-made insole based on the transmitted
surface coordinates.
