control and selection circuitry electrically coupled to the
imaging assembly and the illumination assembly to actuate
the imaging assembly and selectively energize the first
illumination source to image and decode the first dataform
and to actuate the imaging assembly and selectively
energize the second illumination source to image and decode
the second dataform.
See Appellants’ independent claims 1, 11, 15 and 25.
As pointed out above, the Examiner relies on Berson for the
teaching of control and selection circuitry electrically coupled
to the imaging assembly and illumination assembly to actuate the
imaging assembly and selectively energize the first illumination
source to image and decode the first dataform and to actuate the
imaging assembly and selectively energize the second illumination
source to image and decode the second dataform. Upon our review
of Berson, we fail to find that Berson teaches this limitation.
Berson discloses two embodiments. The first embodiment is shown
in figure 2. Berson disclose that the information contained in
bar codes 21 and 31 may be read by utilizing light source 40.
Light source 40 comprises: light sources 41 and 42. Light
sources 41 and 42 have different wavelengths. Source 41 is
utilized to illuminate bar code 21 and source 42 is used to
excite bar code 31. Detector 43 comprises detector 44 and a
detector 45. Detector 44 is utilized to sense bar code 21 and
detector 45 is utilized to sense bar code 31. Detector 44 senses
