and 10, and claims 7 to 9, 11 and 15 to 20 dependent thereon, under 35 U.S.C.
§ 102(a) as anticipated by Mizuno is reversed.
The anticipation based on Greer
We will not sustain the rejection of claims 6 to 11 and 15 to 20 under 35 U.S.C.
§ 102(a) as being anticipated by Greer.
Greer discloses a method and apparatus for calibrating a noncontact gauging
sensor with respect to an external coordinate system. A sensor array is positioned at a
vantage point to detect and calibrate its reference frame to the external reference frame
demarcated by light-emitting reference indicia. The sensor array encompasses a wide
view calibration field and provides data indicating the spatial position of light sources
placed within the calibration field. A tetrahedron framework with light-emitting diodes at
the vertices serves as a portable reference target that is placed in front of the feature
sensor to be calibrated. The sensor array reads and calibrates the position of the
light-emitting diodes at the vertices while the structured light of the feature sensor is
projected onto the framework of the reference target. The structured light intersects
with and reflects from the reference target, providing the feature sensor with positional
and orientation data. These data are correlated to map the coordinate system of the
feature sensor to the coordinate system of the external reference frame. A
